Participation, motivation, and emotional states in the course of VET teacher training: results of an 18-months longitudinal study

Background: Our study aims to investigate inter-and intraindividual effects of trainee teachers’ perceived opportunities of participation in vocational education and training teacher training on their emotional states. Additionally, it is examined whether the subjective reason for action as in intrinsic and extrinsic motivation affects the relationship between perceived participation and emotional states. In this respect, control-value theory constitutes the guiding conceptual framework in our study. Methods: On the basis of a longitudinal design with a total of 75 trainee teachers in Germany and a maximum of 58 survey time points during 18-months of teacher training (in total 1790 individual measurements), we traced the perception of participatory opportunities, intrinsic and extrinsic motivation as well as weekly emotional states. Multilevel modeling allowed us to examine both between-as well as within-person effects of perceived participation. Results: The results of our multilevel models indicate, among other findings, statistically significant within-and between-person effects of perceived participation opportunities on enjoyment, hope, pride, as well as anger, anxiety, shame, and hopelessness. Furthermore, the attributed subjective reason for action, i.e., the intrinsic or extrinsic motivation, moderates the relationship between perceived opportunities to participate and emotional states. Discussion: The findings, which are consistent across different emotions of the same valence and for the two different types of motivation, indicate that those trainee teachers who report low values for intrinsic motivation (or high values for extrinsic motivation) in a given week react more responsively to changes with regard to opportunities for participatory influence.


Introduction
Self-determined participation holds exceptional significance, not only for individuals but also within social practices.It is particularly valued in the educational context as it supports the cultivation of autonomous judgment and action competence 1 (Heid et al. 2023;Kärner et al. 2023).Given the clear and largely predefined formal structures and procedures characterizing teacher training 2 (in Germany), it is crucial to grant trainee teachers sufficient freedom within this framework, emphasizing the importance of providing opportunities for their involvement and co-determination in educational decisions pertinent to their training.As postulated by relevant training regulations, teacher training is intended to enable prospective teachers to fulfill their educational and teaching responsibilities independently and responsibly (e.g., BSPO 2015).This includes, among other things, the expectation that teachers are encouraged to support their students in developing self-determined, reflective, and responsible judgment and actions (KMK 2022) and therefore facilitate active participation among their students (Bergmark and Westman 2018).Thus, the same educational goal is required and addressed in a dual manner.To achieve this goal, it is consequently necessary to promote the development of autonomous rational judgment and action competence among trainee teachers within the context of teacher training, as it is a prerequisite for being able to decide and act independently and autonomously in a certain system.This involves fostering the ability for self-determined participation and influence on decisions by implementing corresponding opportunities during their training.However, the demand for independence and personal responsibility only makes sense if it is not a question of instrumentalizing self-determination for externally determined purposes (Heid 1991a;1991b;2005).
To be able to participate in decisions, trainee teachers need to possess the capability to exert substantial influence on the external characteristics that constitute their learning and working environment.The degree of influence of trainee teachers therefore ranges between perceived heteronomy (trainee teachers believe that decisions relevant to their training are made by others) and autonomy (trainee teachers believe that decisions relevant to their training are made by themselves) (Heid et al. 2023).The differentiation between the categories "autonomy" and "heteronomy" is reflected in the internal perspective of learning and working in different types or qualities of motivation.Possible reasons for the initiation, execution and maintenance of intentional behavior can thus be located on a continuum between intrinsic and various forms of extrinsic regulation (Ryan and Deci 2020).Also, the development of motivation based on self-determination is particularly promoted through the experience of being able to freely choose one's own actions (Deci and Ryan 1993).In principle, learners find motivation when granted opportunities for participation, for instance through offering them considerable choice 1 Following Heid (2001), we understand this to mean the competence not only to solve problems, but also to critically evaluate, define and rationally justify them.Since the solution of work-related problems, as particularly experienced daily by prospective teachers, is not merely a product of applied knowledge and skills, but also an outcome of emotional and motivational processes during the application of such knowledge and skills, so-called non-cognitive facets of competence (especially motivational and emotional dispositions and states) must be taken into account within the context of work-related action regulation (Sembill et al. 2013). 2 With the term teacher training we refer to the second phase of teacher education, the practical in-service training (see Sect. 2.1).
in how they deal with the learning activities in regard to teaching and its organization, collaboration among colleagues, thematic focus, and performance assessment (Aelterman et al. 2018;Kärner et al. 2023;Weiß et al. 2023).
External conditions of learning and control over them as well as internal qualities of action regulation determine emotional responses (Sembill 2010).As emphasized by Pekrun and Perry (2014), a person's inclination towards future learning and engagement with tasks can be significantly shaped by their emotional states.Control-value theory (CVT) postulates that the occurrence of learning and performance emotions depends on whether a person feels that he or she has (or does not have) control over activities and outcomes (e.g., through participation), especially if these have an attributed value (extrinsic and/or intrinsic origin), i.e., are of personal significance (Pekrun et al. 2011;Warwas and Helm 2017).Pekrun (2021) points out that previous research on the processual interplay of emotional states and motivation in teachers has too often focused on interindividual differences (between-person level) in experience and behavior and calls for broadening the perspective to examine intraindividual processes (within-person level) in order to obtain more meaningful research findings.While recent studies in educational research have delved into various emotion-related within-person aspects such as teachers' appraisal-emotions (Frenzel et al. 2020), teachers' emotional experiences (Ruiter et al. 2020), the dynamic between student engagement and teacher emotions (Li et al. 2024) or student emotions (Mainhard et al. 2018), as far as we know, there has been no within-person study on the emotional experiences of trainee teachers within teacher training programs.Yet, within-person analyses, focusing on individual fluctuations of emotional states, offer a deeper understanding of how individual perceptions or responses vary across time.
The aim of this study is therefore to investigate to what extent perceived possibilities of influence on decisive aspects of teacher training cause changes in the emotional state of trainee teachers.In addition, the question arises whether internal regulatory conditions, such as the type of motivation and, in particular, the subjective reasons for initiating and maintaining actions, have an influence on the relationship between perceived opportunities of participation and the resulting emotional states.One focal point of our study involves exploring the differentiation between internal and external values of learning activities and results, an aspect that deserves further exploration within the current literature on CVT.A more nuanced examination of the value component, specifically delving into the distinctions between intrinsic and extrinsic motivation, has the potential to offer new perspectives in regard to the emotional experiences of individuals.We introduce CVT as the guiding conceptual framework in our study, considering participation as an external condition (in terms of CVT as control), while motivation constitutes an internal condition of learning actions (in terms of CVT as value) in teacher training, forming the basis for emotional responses.By examining the teacher training program over a full 18-month duration, our focus extends beyond just between-person analyses identifying distinctions among trainee teachers.Specifically, we are also interested in investigating effects within trainee teachers.The two different analytical perspectives allow us to provide a comprehensive evaluation of participation in teacher training by examining both individual differences and variations within trainee teachers across time in regard to emotional states.On the basis of a longitudinal design with a total of 75 trainee teachers in Germany and a maximum of 58 survey time points during teacher training (in total 1790 individual measurements), we traced the weekly perception of participatory opportunities, intrinsic and extrinsic motivation as well as emotional states.Through multilevel analyses, inter-as well as intraindividual effects of perceived participation will be examined.
The article is structured as follows: Following the description and contextualization of vocational education and training (VET) teacher training, we provide an overview of theoretical approaches and empirical findings on perceived participation opportunities, subjective motivational values and emotional states.Ultimately, corresponding hypotheses are derived.Subsequently, the methodological approach is presented, encompassing the study design, description of measures, the empirical model and data analysis.The next section presents our empirical findings, followed by a comprehensive discussion of the results.

The context of VET teacher training in Germany and the tension between autonomy and heteronomy
According to the OECD (2021, p. 91), "initial teacher education and training (ITET) for the VET sector is highly variable", meaning that not only the entry requirements differ among countries, but also the provision regarding the formal organization (e.g., the institutions in charge).However, they all have in common to equip prospective teachers with sufficient pedagogical as well as subject-specific expertise to adequately prepare their students for professional practice.In Germany, where the present study was conducted, teacher education is divided into two parts: a more theoretical phase at a university or college of education (including several weeks of a teaching internship in a vocational school) and a practical in-service phase (lasting 1-2 years, depending on the federal state), often referred to as the "second phase" of teacher education or "preparatory service".This second phase is characterized by two learning sites, the training school3 and the college of didactics and teacher education (see also Weiß et al. 2023).As part of the teacher training program, performance is assessed over the entire duration and with regard to various examinations, starting with numerous feedback sessions, oral examinations, a written paper on a comprehensive teaching unit held, principal evaluations and teaching demonstrations, assessed with grades by seminar teachers who observe these lessons.During this second phase, trainee teachers must frequently interact with their mentors (experienced teachers) in the training school as well as with their seminar teachers who are responsible for training in didactics and subject-related competencies at the college of didactics and teacher education.At this point, the question arises of how much prospective teachers can (and/or want to) participate in the decisions made by their training instructors.While many aspects of the training are externally predetermined (timetable, curriculum, assessments, etc.) it is precisely the situations and interactions with the training mentors and seminar teachers that inherently provide opportunities for participation and co-determination.It is important to emphasize that the key objective of teacher education and training is to prepare and empower prospective teachers to work and learn independently in their (future) profession (BSPO 2015;Messner and Reusser 2000).For this reason, the external conditions during training should be designed in such a way that individuals can act and make decisions (at least to some extent) independently.As pointed out by Valenčič and Vogrinc (2007) in this context, mentors in particular are often faced with the dilemma of when help and support becomes an interference in the trainee's work.The question therefore arises as to how autonomy can be realized within a training framework that is sometimes relatively rigidly structured.According to Helsper (2016) professional action is characterized by more or less clear asymmetries between instructors and their learners or trainees and thus by more or less unequal distribution of power.This structural power imbalance renders professional actions inherently vulnerable to various forms of power abuse.In this context, participation provides an opportunity for learners to actively engage in their own development process and enhance their autonomy, precisely in order to address and mitigate existing power imbalances or to counteract the prevailing structural inequity.Helsper (2016) describes the paradoxical relationship between autonomy and heteronomy in professional practice as follows: When professionals, such as seminar teachers or mentors, intervene in a supportive and facilitative manner to promote autonomy-for example, by providing ample opportunities for participation-the result may paradoxically be that dependency is increased, any autonomy that may already exist is decreased, and consequently heteronomy is promoted.For instance, extensively involving the trainee teacher in collaborative lesson planning could unintentionally foster dependency if the trainee teacher relies heavily on the mentor for guidance, leading to heteronomy.

Participation, motivation and emotional states within the framework of control-value theory
By incorporating CVT as the guiding conceptual framework in our study, we regard participation as an external condition (within the context of CVT referred to as control), while motivation is seen as an internal condition influencing learning actions (within the framework of CVT referred to as value) in teacher training.CVT suggests that emotions related to learning and performance are influenced by an individual's perception of control over activities and outcomes.This perception, particularly when activities hold personal significance due to the attributed value, can determine the occurrence of emotions (Pekrun et al. 2011).Against this background, the following sections will provide a closer examination of the three central concepts mentioned and their interplay.

Perceived participation opportunities in teacher training
If one considers possible fields according to which external learning opportunities in teacher training can be described in more detail in terms of content and process, then the learning objectives and learning content, aspects of social and didactic-methodical design, structuring and organization of the learning opportunities as well as applied forms of examination and assessment criteria can be identified as essential dimensions (e.g., Hauk and Gröschner 2022;Kärner et al. 2023).In determining the content of these very decision fields, trainee teachers in principle have the possibility of influencing the corresponding decisions.In this context, we understand participation as the involvement of trainee teachers in "decision-making and will-forming processes" (Reichenbach 2007, p. 54), which includes a dialogue between the learners and other decision-makers (e.g., seminar teachers or mentors) (Mager and Nowak 2012).In order to achieve participation, trainee teachers must be able to exert a significant influence on decisions relevant to their training, i.e., they must be able to choose actions from a defined set of options for action.This also includes the possibility to decide against something, which in turn presupposes corresponding freedom of action and decision-making with regard to the external conditions of their will and action (e.g., Habermas 1974;Heid 1991a;Oser and Biedermann 2007).At this point, it becomes clear that the learner's freedom of action and decision-making can be more or less pronounced in the training context (e.g., due to organizational and procedural restrictions or opportunities).The degrees of trainee teacher influence therefore range between perceived and/or actual external control (relevant decisions are made externally from the trainees' points of view) and autonomy (trainees make the relevant decisions independently) (summarized and described in more detail in Heid et al. 2023 andKärner et al. 2023).
Depending on the specific context, perceived control in CVT can mean, for example, that there are opportunities to participate in shaping the (learning) environment and outcome.The perception of sufficient internal control over activities and their outcomes is the central prerequisite for the expectation that success can be achieved or failure prevented (Pekrun et al. 2007).Also, assuming that learner development is largely determined by complex interactions between the learner with his/her individual learning prerequisites and the characteristics of the learning environment (Kärner and Kögler 2016), it could be postulated that institutionalized educational processes should make it possible to do justice to the individual differences between learners in terms of their development opportunities.One possible way to ensure this is for learners themselves to influence the momentous decisions that underlie the design of such educational processes and thus to provide them with a certain degree of control over learning situations.Learners would therefore have to be given opportunities to constructively participate in determining the spectrum of assessment characteristics that require justification or ways of achieving goals (Heid 1992;Heid et al. 2023;Kärner et al. 2023).The basis of justification aimed at the interaction between the person and the (learning) environment refers, in the sense of self-organization processes, to the assumption of a self-determined emergence of order, which represents an action-regulated process within the person, but also between persons and in the person-environment interaction (Sembill 1999).

Intrinsic and extrinsic motivation of trainee teachers
The differentiation between the categories of autonomy and heteronomy is reflected in the internal perspective of learning in different types or qualities of motivation, which are described in more detail in the context of the self-determination theory (SDT) of motivation (Ryan and Deci 2020).Possible reasons for initiating, executing, and maintaining intentional behavior can thus be located on a continuum of relative self-determination whereby the perceived location of action execution shifts between intrinsic and extrinsic motivation: In the case of intrinsic motivation learning actions are initiated, executed and maintained due to their own will and out of pure object-related interest, without a need for consequences that can be separated from the action to maintain the learning action; in the case of extrinsic motivation, an action is carried out due to its factual or anticipated external consequences and not of one's own volition, which can be expressed, for example, in carrying out an activity in order to meet the specified requirements.The learning and working environment plays a special role in the genesis of the above-mentioned motivational qualities by supporting or thwarting the satisfaction of basic psychological needs, e.g., for autonomy (see Weiß et al. 2023) in the sense of the above-mentioned freedom of action and decision-making, since, for example, the satisfaction of the need for autonomy promotes the development of intrinsic motivation (Ryan and Deci 2020;Scheja 2009;Sembill and Scheja 2008;Kärner et al. 2023).
The subjective value attributed to activities and outcomes within CVT can be intrinsic or extrinsic in origin, i.e., they are of personal significance (Pekrun et al. 2011;Warwas and Helm 2017).Intrinsic values are defined as activities that are valued per se or are enjoyable and do not necessarily produce an outcome (Pekrun et al. 2007).In contrast, extrinsic values encompass the instrumental use of activities in generating desired outcomes and the ability of these outcomes to potentially trigger further consequences (Heckhausen 1991).In our theoretical model, we refer to intrinsic and extrinsic importance of activities in teacher training and distinguish between intrinsic and extrinsic motivation, as motivated behavior ultimately affects emotional states (Seifried and Sembill 2005).Several studies utilize a single dimension approach of value.Yet, we differentiate between intrinsic and extrinsic value appraisals, following Simonton and Garn (2020) and recommendations from Pekrun and Perry (2013), who advocate for this due to their conceptual differences.Additionally, Frenzel et al. (2007) underscore the importance of considering the dual dimensions of value appraisals.Götz et al. (2010) have derived from appraisal theories that a higher degree of personal relevance or attributed value with regard to an activity or outcome is associated with higher levels of positive emotional experiences.Specifically, CVT implies that subjective values influence both the type of emotion experienced and its intensity.The intensity of the experienced emotion is suggested to depend on the degree of subjective value, including one's interest level or motivation in specific learning material or the perceived significance of success and failure in an exam (Pekrun et al. 2007).

Emotional states of trainee teachers
The conception of emotional states is understood as an emotionally motivationally characterized, subjective and situation-specific experience of a mental state.In contrast to stable, person-related emotional traits, these emotional states can take on different as well as continuously varying characteristics within and between individuals during the course of the teacher training program (Sembill 1992;2010).They can occur as a trigger, concomitant and/or consequence of cognitive (i.e., information-processing) processes and represents an essential component of action regulation processes (Achtenhagen et al. 1988;Schumacher 2002;Sembill 1992).Sembill (1992) emphasizes the need to constructively include the emotional states and needs of learners in didactic efforts and to understand them as a constitutive element for the acquisition and change of knowledge.
In the context of the CVT, Pekrun et al. (2007) describe achievement emotions as emotions that are directly related to achievement activities or outcomes.In the context of teacher training, emotional states affecting learning and performance can be considered as achievement emotions, as trainee teachers in particular are subject to continuous assessments.On the one hand, they engage in self-evaluation and reflection of their own performance and practice.This assessment encompasses various dimensions, such as the overall effectiveness and success of the lesson they have conducted, the extent to which students have acquired knowledge during class, an evaluation of their pedagogical competencies beyond the scope of subject expertise, and their ability to integrate and execute recommendations provided by their instructors.On the other hand, they are implicitly evaluated by students (e.g., through facial expressions, gestures and body language as well as expressed satisfaction), whereas they are explicitly evaluated for their performance by colleagues, mentors, seminar teachers, or the school principal via feedback and grades.
Emotional states play a particularly important role in the teaching profession, as teaching is associated with high demands and low control, which often results in emotional exhaustion and increased teacher turnover (Shackleton et al. 2019).In this context, Aprea et al. (2023), for example, report from a broad-based longitudinal study that teachers at vocational schools work noticeably longer hours than the specified weekly working hours.In turn, weekly working hours correlate positively with the perception of stress and the risk of burnout and negatively with well-being and job satisfaction.Especially against the background of the shortage of teachers in many countries (e.g., UNESCO 2023), an adequate understanding of the underlying processes linked to emotional states seems to be indispensable in teacher training (Sembill and Kärner 2020).Accordingly, it has been acknowledged by, for example, Schutz et al. (2007) and Sutton and Wheatley (2003) that gaining a deeper insight into the emotions and emotional processes of (trainee) teachers holds promise for enhancing pre-service teacher education programs.

Interdependencies between participation opportunities and motivation with regard to emotional states
A crucial aspect of CVT lies not solely in assuming a direct effect between control or subjective value and resultant emotional states.Rather, it posits that both assessments of control and value appraisals impact achievement emotions in a multiplicative manner (Pekrun 2006).Emotions with positive valence (e.g.enjoyment, hope, or pride) arise when control and subjective value are high, while emotions with negative valence (e.g.anger, anxiety, shame, hopelessness, or boredom) occur when both factors are low.In this context, Pekrun et al. (2007) argue that the impact of perceived control on achievement emotions is moderated by the subjective value (of intrinsic or extrinsic nature).CVT emphasizes the mutual reinforcement of control and value: if both factors are present to a sufficient degree, they reinforce each other in their effect and the emotional reaction becomes more intense (Götz et al. 2010;Pekrun 2006;Pekrun et al. 2007; for an application of CVT in the VET context, see Kögler and Göllner 2018).From a statistical point of view, the sign of the regression weight of the interaction between control and value would be positive in this case.In addition to the assumption of mutual reinforcement, as postulated by the CVT, the assumption of mutual compensation is also conceivable and plausible.In terms of content, this would mean that a lack of perceived control could be compensated for by a higher subjective value.From a statistical point of view, the sign of the regression weight of the interaction between control and value would be negative in this case.

Hypotheses
Against the background of the theoretical assumptions and relationships between perceived participation opportunities, motivation in the sense of subjective reasons for action, and emotional states described above, we formulate the following hypotheses, which are tested in our empirical study.
-H1: Greater perceived participation, in the sense of being able to influence the (learning) environment, corresponds positively with the emotional states of enjoyment, hope, and pride, and negatively with the emotional states of anger, anxiety, shame, hopelessness, and boredom.-H2: The attributed subjective reason for action, i.e., the intrinsic or extrinsic motivation, is positively associated with the emotional states of enjoyment, hope, and pride, and negatively with the emotional states of anger, anxiety, shame, hopelessness, and boredom.-H3: The attributed subjective reason for action, i.e., the intrinsic or extrinsic motivation, moderates the relationship between perceived opportunities to participate and emotional states.

Study design
Based on a longitudinal design, weekly short questionnaires were conducted at a total of 58 data collection points (weeks) over the 18-month period of teacher training, resulting in 1790 individual measurements from 75 trainee teachers. 4We chose the experience sampling method in a weekly diary format as the survey method.In view of the total duration of teacher training (18 months), the weekly survey frequency enabled us to achieve a relatively high measurement density and an interval-contingent survey plan.
A major advantage of such a survey method is that diary data is generally more valid (e.g., ecological validity) than data obtained from retrospective measurements (for an overview of the experience sampling and diary method see Rausch et al. 2022 and Seifried and Rausch 2022).As not all trainee teachers provided information for every week in the questionnaire, the average response rate was around 24 surveys per person with Bottling et al. Empirical Res Voc Ed Train (2024) 16:7 a standard deviation of around 21 surveys.In order to keep the effort for participants as low as possible, no data was collected during school vacations.Our data collection began in January 2022 and ended in July 2023.Participants were invited to take part in the questionnaire by email at the end of the working week (Friday), for which they had time to complete it over the weekend.
The sample is a full census conducted at one of four teacher training institutions for vocational schools in the federal state of Baden-Württemberg (BW), Germany.This sample is representative for the training cohort in terms of socio-demographic characteristics that began their training in the same year in the aforementioned federal state.Our sample includes 54 females (62.79%), which closely mirrors the gender distribution of female trainee teachers in BW (60.05%).A chi-square analysis revealed that the ratio of males to females in our sample did not show a statistically significant deviation from the other VET training institutions in BW with respect to the observed gender distribution [χ 2 (1, n = 388) = 0.346, p = 0.557].Additionally, the average age of participants in our sample is 29.63 years, which matches the average age of the population at 29.70 years.A t-test further indicated that there is no significant difference in the average age of our participants compared to other VET training institutions in BW [t(380) = 0.140, p = 0.889].
The study received approval from the relevant government authority, and all trainee teachers willingly consented to their involvement in the study and the use of their data.As an incentive for regular study participation, a total of €1000 was raffled off among all participants.In order to take part in the prize draw, at least 50% (29) of all 58 questionnaires had to be completed.A higher participation rate increased the chances of receiving a higher expense allowance.5

Perceived participation opportunities
The subjective experience of being able to influence one's environment can sometimes deviate from the actual (objective) situationally given opportunities for influence or autonomy (cf.e.g., Meyer-Ahrens et al. 2010).In the course of operationalizing perceived participation opportunities, we deliberately decided to ask study participants about their subjective experience as a phenomenally-conscious and articulable state, i.e., their sense of opportunities to exert influence.The reason for this is that the trainees are our only source of information and we therefore assumed that they would be able to provide more valid information about their subjective experience of participation opportunities than about the factual objective conditions.When examining external learning opportunities, various dimensions can be identified that allow for considerable learner influence (summarizing Kärner et al. 2023): the consideration of aspects of social interaction, the structuring and organization of learning opportunities, the definition of learning objectives and content as well as aspects related to the forms of examination or assessment criteria used (e.g., Hauk and Gröschner 2022;Reisenauer 2020;Weinert 1982).Our self-developed items for assessing perceived participation opportunities are based on these theoretical considerations on possible dimensions of participation as well as on the empirical work by Kärner and Jüttler (2024) capturing perceived participation in educational settings in terms of collaboration, organization of work, content definition, and performance evaluation.Participants were asked how strongly they agreed with each of the four items for the respective week, measured on a six-point Likert-type scale ranging from (1) do not agree to (6) totally agree.The exact wording of the items can be found in Table 1.
A two-level confirmatory factor analysis (CFA; Chou et al. 2000) was conducted to test whether our four perceived participation items reliably measure the facets of a joint perceived participation construct in teacher training and thus load on one common factor, both within and across individuals.For the evaluation of model fit in structural equation modeling, we followed recommended cut-off values for the fit indices (see Homburg and Baumgartner 1995;Marsh et al. 2004;Homburg et al. 2008).With respect to reliability, we refer to McDonald's coefficient omega (hierarchical; ω h ) as an estimate of the general factor saturation of a test.ω h offers a quantitative estimation indicating the extent to which the scale measures its overarching factor (Zinbarg et al. 2006).The multilevel confirmatory factor analysis provides sufficient evidence to adopt a common factor (χ 2 (4) = 15.592,p = 0.004; CFI = 0.986; RMSEA = 0.040; SRMR within = 0.021; SRMR between = 0.020) with reliabilities ω within = 0.611 and ω between = 0.907.All model fit indices are within the recommended cut-off values, indicating that the model fit can be considered as good.Whereas reliability on the within-person level was acceptable (Yang et al. 2022), it was excellent on the between-person level.With regard to the factor loadings, these were moderate at the within-person level and moderate to high at the between-person level (see Fig. 1).As all factor loadings were statistically significant, it underscored the presence of systematic common variance among the items and, as a result, provided sufficient support for the calculation of one participation scale across all items.

Intrinsic and extrinsic motivation
To assess the extrinsic and intrinsic subjective reason for action attributed to the activities during teacher training, one single item for each type of motivation was used, aiming to reflect extrinsic and intrinsic motivation.In this context, we deliberately opted for the utilization of single items due to our sort of weekly experience sampling method, which involved the administration of brief, user-friendly surveys.This decision is grounded in a thorough consideration of scientific recommendations regarding the use of single items (e.g., Allen et al. 2022;Matthews et al. 2022).
The items were self-constructed, but in accordance with SDT and inspired by existing instruments such as the Academic Motivation Scale (AMS-C 28) College Version (Vallerand et al. 1993) or the scales of Prenzel et al. (1996).Both items were measured on a six-point Likert-type scale ranging from (1) never to (6) always.Again, the exact wording of the items is listed in Table 2.

Emotional states
In order to evaluate the emotional responses in each week of teacher training we implemented in total eight items, which are intended to capture the emotional states of trainee teachers.According to Keller et al. (2014, p. 69), who refers to Lazarus (1991) in his explanations, almost all emotion theories assume that emotions are extremely variable and have subtle differences, and many emotion researchers believe "that broad dimensions such as positive vs. negative affect are not sufficient to accurately describe the occurrence of emotions".As we share this view, we consider our individual emotional states in a very differentiated way and refrain from creating a common scale for emotional states with positive vs. negative valence.One distinct item was assigned to each emotional state, encompassing enjoyment, hope, pride, anger, anxiety, shame, hopelessness, and boredom.The formulation of the items was conducted based on the Achievement Emotion Questionnaire (AEQ) (Short) and adapted to our survey context (Bieleke et al. 2021;Pekrun et al. 2011).All items were assessed utilizing a six-point Likert-type scale, spanning from (1) never to (6) always.Table 3 sets forth the precise wording of these items.

Statistical modeling and data analysis
As outlined in the previous sections, the aim of our empirical study is to investigate the relationship between perceived opportunities to influence aspects relevant to training and changes in the emotional state of trainee teachers.In addition, the question arises whether internal regulatory conditions, such as the type of motivation and in particular the subjective reasons to initiate and maintain actions, affect the emotional states directly as well as the aforementioned relationship between perceived participation opportunities and the resulting emotional states.In the following, we transfer the ideas of underlying psychological mechanisms regarding the effect of weekly6 perceived participation opportunities and weekly motivation on weekly emotional states of trainee teachers to our empirical model and describe the applied empirical approach accordingly.The emotional state of trainee teacher j during week w (emot_states wj ) is predicted (a) based on the trainee's weekly perceived participation (perc_part wj ) and the trainee's weekly motivation (mot wj ), which were centered on trainee j's person-mean of perceived participation opportunities and trainee j's person-mean of motivation, respectively, thus isolating a solely within-person effect (e.g., Kramer et al. 2021;Raudenbush and Bryk 2002) and (b) based on trainee j's mean of all perceived participation (perc_part_pmean j ) and motivation reports (mot_pmean j ), centered on their respective grand-means, representing the between-person effect.The model also incorporated random effects for both the intercept and the slope of perceived participation opportunities as well as motivation.The following equations describe our model.
Level 1 (within trainee teachers): Level 2 (between trainee teachers): Moreover, for the assessment of intraindividual differences in intraindividual effects, we carried out a within-level (level 1 × level 1) moderation analysis, which tends to be rarely used in scientific studies due to the fact that experience sampling or extensive longitudinal data is required, and many studies are still conducted cross-sectionally.In this way, more detailed information can be derived at the person level, which improves the understanding of processes that take place within individuals.This was implemented by adding the interaction term (perc_part wj × mot wj ) to our model, constituting a fixed effect. 7The equation on level 1 is therefore extended as follows.
(1) to (5): -β 0j is the mean of the emotional state of trainee teacher j; -β 1j represents the randomly varying slope parameter for perceived participation; -β 2j represents the randomly varying slope parameter for motivation; (1) The effect was not randomly estimated in order to avoid convergence problems.
-β 3 represents the fixed slope parameter for the interaction term; -γ 00 is the average emotional state across all trainee teachers and measurement times (weeks), i.e., the grand mean; -γ 10 represents the average slope parameter for perceived participation; -γ 20 represents the average slope parameter for motivation; -γ 01, γ 02 and γ 11 are the parameters to be estimated; -υ 0j , υ 2j are the deviations of the mean value of trainee teacher j from the mean value across all trainee teachers and measurements (weeks), i.e., the level 2 random effect (level 2 residual variance); and -ε wj is the deviation of the measurement at week w from the average emotional state of trainee teacher j (level 1 residual variance).
The following Fig. 2 graphically illustrates the analysis model on both levels.
In order to test the empirical model described above on the basis of the collected data, we estimated in total 16 two-level models.Multilevel models split the residual variance of the dependent variable, i.e., the emotional states, into two (statistically orthogonal, i.e., independent) variance components: -Variance within level 2 units (intra-individual variability): Var(ε wj ) -Variance between level 2 units (inter-individual variability): Var(υ 0j ) The ratio of the level 2 variance to the total variance is the intraclass correlation coefficient (ICC), which is reported in Table 4.The respective ICC across all variables falls within the range of 0.30-0.57,indicating that there is both variance within trainee teachers (observations of an individual vary) and variance between trainee teachers (there are differences between individuals), which justifies the analysis of both levels.Multilevel models were employed to address the nested hierarchical structure within the data.Likelihood ratio tests were employed to assess the significance of random effects by comparing the model's fit with and without the corresponding random variance.If Fig. 2 Hypothetical models for analysis.perc_part perceived participation opportunities, mot motivation, emot_states emotional states random variances are not estimated, despite the presence of random variances in the parameters, "Type I error rates can be badly inflated" (Baird and Maxwell 2016, p. 187).
Starting with a null model to estimate the variability of trainee teachers' reports of their experienced emotional states, we subsequently included predictors as in perceived participation opportunities and intrinsic or extrinsic motivation to test main effects at each level.Following this, we analyzed interactions while controlling for the direct effects.In order to determine both inter-and intraindividual differences in intraindividual effects, we conducted cross-level (level 1 × level 2) and within-level (level 1 × level 1) moderation analyses.However, for the former, we did not find significant differences with respect to gender and age in the intraindividual effect of perceived weekly participation on emotional states of a trainee teacher.For the latter, we first conducted eight models incorporating perceived participation and intrinsic motivation as the potential moderator, each utilizing one of the following weekly emotional states as a dependent variable: enjoyment, hope, pride, anger, anxiety, hopelessness, shame, and boredom.Similarly, we have added eight additional models that consider the potential moderator of extrinsic motivation.8All statistical analyses were performed in R (version 4.2.1 using the nlme package from Pinheiro et al. (2018) for estimating the multilevel models; the model parameters are based on restricted maximum likelihood estimations).In each of our analyses, we applied the standard α-level of 0.05 (two-tailed).

Descriptive data and correlations
Table 4 contains descriptive data (mean, standard deviation and ICC) as well as Pearson correlation coefficients on the within-person level (below the diagonal) and on the between-person level (above the diagonal).
With regard to the descriptive values, it can be seen that, on average, an above-average number of opportunities for participatory influence are reported (M = 4.21; 4 = often and 5 = very often).Extrinsically motivated reasons for action (M = 4.23) tend to reach higher approval ratings than intrinsic ones (M = 3.75; 3 = sometimes and 4 = often).Emotions with positive valence (enjoyment: M = 4.17, hope: M = 3.91, pride: M = 3.45) each achieve higher approval ratings on average than emotions with negative valence (shame: M = 1.72 to anxiety: M = 3.13; 1 = never, 2 = rarely, and 3 = sometimes).
Pearson correlations at the within-person level show positive correlations of medium strength9 of perceived participation with the emotional states of enjoyment, hope, and pride, and negative correlations of medium strength with the emotional states of anger, anxiety, shame, and hopelessness.In addition, perceived participation corresponds positively with intrinsic motivation.Pearson correlations at the between-person level show strong positive correlations of perceived participation with the emotional states of enjoyment and hope, and negative correlations of medium strength with the emotional states of anger, anxiety, shame, hopelessness, and boredom.Moreover, perceived participation corresponds positively with intrinsic (strong effect) and extrinsic (small effect) motivation.Intrinsic motivation at the within-person level shows medium to strong positive correlations with all emotional states having a positive valence as well as negative small to medium correlations with all emotional states having a negative valence except for boredom (not statistically significant).At the between-person level intrinsic motivation is significantly correlated with all emotional states-again showing medium to strong positive (negative) associations with the emotional states that have a positive (negative) valence.Extrinsic motivation at the within-person level is negatively correlated with hope and boredom as well as positively correlated with pride, anxiety, and hopelessness.All these Pearson correlations are small in effect size.Also, we found that extrinsic motivation corresponds positively with enjoyment, hope and pride (medium effects) and negatively with shame and boredom (medium effects) at the between-person level.

Table 4 Descriptive data and Pearson correlations
To assess the development of the analyzed variables over time, we have depicted the development of all variables on a weekly average in Fig. 5 in the Appendix section.It is particularly noticeable that there is no clearly recognizable monotonic trend in the data,10 intrinsic motivation reached permanently lower average values than extrinsic motivation, and positive emotions have permanently higher average values over time than negative emotions, with the exception of anxiety.Moreover, it can be seen that the mean value curves for intrinsic motivation and participation develop quite similarly, whereas extrinsic motivation tends to move in the opposite direction.Finally, when emotions with positive valence rise, those emotions with negative valence tend to fall.The graph also contains some central occurrences during teacher training.

Likelihood ratio tests: fixed vs. random slope models
As we assume that the effects of perceived participation opportunities on emotional states vary across individuals, we compared our random slope models to the less complex fixed slope models and conducted likelihood ratio tests to test whether the integration of random effects improves the model fit.

Effects of perceived participation opportunities on emotional states
First, we refer to the intra-as well as interindividual effects of perceived participation opportunities on emotional states of trainee teachers (see Tables 5, 6, 7 and 8 As expected, this can be seen both in the model that simultaneously considers intrinsic motivation (Models 1a-g) and in the model that at the same time includes extrinsic motivation (Models 2a-g).The findings indicate that trainee teachers report more enjoyment, hope, and pride as well as less anger, anxiety, shame, and hopelessness in weeks in which they perceive more opportunities to influence decisions   For pride and boredom, however, the effect is only statistically significant in the model that incorporates extrinsic motivation (Model 2c and 2h).

Effects of motivation on emotional states
Next, we address the direct intra-and interindividual effects of the subjective reason for action, i.e., motivation, again on emotional states of trainee teachers.In regard to the within-person effects of intrinsic motivation, the multilevel models reveal statistically significant effects on all emotional states except for shame and boredom, meaning that trainee teachers experience emotions with positive valence stronger (Model 1a: b = 0.331, p < 0. For extrinsic motivation we found fewer statistically significant direct effects compared to intrinsic motivation.On the within-person level extrinsic motivation has a positive effect on pride (Model 2c: b = 0.090, p = 0.012) as well as on anxiety (Model 2e: b = 0.228, p < 0.001) and a negative effect on boredom (Model 2h: b = −0.104,p = 0.001).This means that trainee teachers experience more pride but also more anxiety and less boredom in weeks in which they are more extrinsically motivated.Finally, and on the between-person level our models show statistically significant effects of extrinsic motivation on enjoyment (Model 2a: b = 0.344, p < 0.001), pride (Model 2c: b = 0.375, p = 0.003), and boredom (Model 2h: b = −0.305,p = 0.009).Thus, trainee teachers who are more extrinsically motivated on average, feel generally more enjoyment and pride and less boredom.Bottling et al.

Effects of the interaction between perceived participation opportunities and motivation on emotional states
Overall, we found six significant interaction effects on the within-person level in our 16 models, with intrinsic motivation serving as a moderator in a total of four cases and extrinsic motivation in two cases.5, 6, 7, and 8 Bottling et al. Empirical Res Voc Ed Train (2024) 16:7

Summary of findings in the light of our hypotheses
In this concluding section, we will discuss our results against the background of our presented in Hypotheses section.In support of hypothesis H1, on the within-person level our results reveal a significant positive effect of perceived participation opportunities, characterized by the weekly capacity to influence the learning and working environment, on the weekly experienced emotional states of enjoyment, hope, and pride.Conversely, a notable inverse (negative) effect is observed on the emotional states of anger, anxiety, shame, and hopelessness.Overall, this corroborates the notion that during weeks of increased sense of agency and influence within the learning and working context more positive emotional experiences are induced, while diminished perceived participation opportunities correspond with negative emotional states.As for the emotional state of boredom, there is insufficient evidence to substantiate H1.The results on the betweenperson level also provide evidence supporting the validity of H1.Trainee teachers who, on average, indicate a higher frequency of perceived participation tend to experience increased levels of enjoyment, hope, and pride.This aligns with the study of Götz et al. (2010), who obtained similar results regarding H1 and the emotions of enjoyment and pride for university students.The authors, in this context, define "control" as the subjective perception that, according to individual assessment, the situation is under one's own management or influence.Similarly, Jenßen et al. (2021) found that control appraisals of pre-service teachers have a large effect on their enjoyment.Additionally, we found that trainee teachers reported lower levels of anxiety, shame, hopelessness, and boredom.Notably, no significant effect was observed for the emotional state of anger on this between-person level.
In regard to hypothesis H2, which posits hat the subjectively attributed value, encompassing both intrinsic and extrinsic aspects of an activity, has a positive effect on the emotional states of enjoyment, hope, and pride, which can be confirmed for intrinsic motivation on the within person-level as well as on the between-person level.These findings collectively underscore the robustness of the association between perceived value and positive emotional outcomes, contributing valuable insights to our understanding of the motivational dynamics involved in emotional experiences of trainee teachers.For extrinsic motivation, however, the assumption can only be partially supported, as on the within-person level we only find a positive effect on pride and on the between-person level our models reveal positive effects again on pride and also on enjoyment.For the emotional states with negative valence, we found that in weeks with higher levels of intrinsic motivation, anger, anxiety, and hopelessness are less pronounced (within-person level) while more intrinsically motivated trainee teachers also experience less anger and boredom on average (between-person level).Only for intraindividual reported shame and boredom as well as interindividual experienced anxiety, hopelessness and shame we did not find evidence to support H2.Other research correspondingly discovered that the attributed value is positively linked to enjoyment and pride (Götz et al. 2010;Jenßen et al. 2021) and negatively associated with boredom (Kögler and Göller 2018).
Moreover, it is particularly interesting that the only within-person effect that changes its direction with respect to the two predictors, intrinsic vs. extrinsic motivation, is related to the emotional state of anxiety.While intrinsic motivation leads to trainee teachers being less anxious, extrinsic motivation is associated with a higher level of anxiety.This can be justified by considering that intrinsic motivation, emanating from within the individual based on their own will and/or genuine interest, fosters a positive emotional state that acts as a protective factor against anxiety.Conversely, extrinsic motivation, driven by external rewards or pressure, can introduce stressors that contribute to an elevated emotional state of anxiety among trainee teachers.These findings are consistent with previous research (e.g., Ahmetović et al. 2020;Gkonou 2013).
Our analysis also revealed intraindividual differences in intraindividual effects, i.e., significant interaction effects between perceived opportunities of participation and the types of motivation.Hypothesis H3, suggesting a multiplicative influence of the interaction between perceived participation opportunities and subjective intrinsic value (i.e., intrinsic motivation) on the emotional states of trainee teachers, is supported by our empirical findings.For trainee teachers who report above-average intrinsic motivation in a given week, the influence of participation on enjoyment as well as hope is diminished.In essence, for trainee teachers experiencing increased intrinsic motivation in specific weeks, perceived participation no longer exerts as pronounced an impact on these two emotional states with positive valence.In summary, the actually positive correlation between perceived participation and emotional states becomes weaker.Conversely, this also applies to the emotions with negative valence, as the actually negative relationship is also weakened.In other words, it can be stated that in weeks in which trainee teachers perceive fewer opportunities for participation, above-average intrinsic motivation compensates for the perception of anxiety and hopelessness.For the emotional state of anger this is also true yet only for a significance level of 10% (Model 1d: b = 0.055, p = 0.074).Thus, our findings show, that the joint impact of perceived participation opportunities and intrinsic motivation contributes significantly to influencing the emotional states, highlighting the combined effect on trainee teachers.
Ultimately, we also found evidence for H3 with respect to extrinsic motivation: In contrast to the aforementioned results, for trainee teachers who report above-average extrinsic motivation in a given week, the negative effect of perceived participation on anger as well as hopelessness is greater and thus amplified, meaning that trainee teachers are less angry or hopeless.Therefore, the empirical evidence affirms the hypothesized multiplicative impact of the interaction between perceived participation opportunities and the subjective extrinsic value (i.e., extrinsic motivation) on the emotional states of trainee teachers, namely anger and hopelessness.In this respect, Weiß et al. (2023) found that a participation-friendly or autonomy-promoting environment can already contribute to a positive experience among trainee teachers during teacher training.
Overall, our analyses indicate that within the framework of CVT, it is pertinent to view the subjective value as a dual dimension.This is evident because models considering intrinsic motivation differ from those focusing on extrinsic motivation.For instance, a significant within-level effect of intrinsic motivation on enjoyment and anger is observed, whereas such an effect is absent in relation to extrinsic motivation.The findings in this case are consistent with the assumptions of CVT, which suggests that intrinsic values correspond with emotions linked to learning and activity (this category also encompasses enjoyment and anger), whereas extrinsic values are likely to align with emotions associated with outcomes and achievements, such as pride or anxiety (Pekrun et al. 2007).The significant interaction effects of the within-level moderations also differ depending on the type of motivation (extrinsic vs. intrinsic) and call for a differentiated consideration.These results are in line with Simonton and Garn (2020), who also identified an effect of (only) intrinsic value on enjoyment and argued for a separate treatment of subjective value.
Apart from our hypotheses, another intriguing observation arises from the data: trainee teachers exhibit notably higher levels of extrinsic motivation on average over time compared to intrinsic motivation, a trend clearly depicted in Fig. 5 (in the Appendix section), where, in certain instances, a difference of more than one scale unit between the two motivational types is evident.Possible explanations for this phenomenon include the fact that trainee teachers' performance is evaluated through "external reinforcers" (Morris et al. 2022(Morris et al. , p. 1802) such as grades, which, according to research, tends to promote extrinsic motivation (Lin et al. 2003;Morris et al. 2022).Given that performance assessments are conducted by individuals within the training environment (seminar teachers, principals, etc.), trainee teachers naturally strive to meet their expectations and fulfill their requirements.Moreover, the potential for earlier civil servant status, contingent upon performance during teacher training, presents an added incentive for securing a more stable job position.

Limitations of the study
Despite the valuable insights gained from this study, there are several limitations that must be taken into account when evaluating our results.Firstly, due to organizational constraints, we were only able to collect data from one of the four VET teacher training locations in the state of BW.However, the sample is representative for the training cohort in terms of the socio-demographic characteristics gender and age that began their training in the same year in the aforementioned federal state.In addition, our sample is comparable to trainee teachers in other federal states in terms of age and gender.In Bavaria, for example, roughly two-thirds of all trainee teachers at vocational schools were between 27 and 32 years old in 2022, with a proportion of men in this group being below 40% (Bavarian State Office for Statistics 2022).In Hamburg, for example, the average age of trainee teachers at all school types in 2024 was 29.8 years with a male proportion of 29.5% (Zeller 2024).While a larger sample would have been desirable and the results may only be transferable to other contexts with restrictions in this respect, our chosen study design made it possible to collect a total of 1790 individual measurements, which provided remarkable insights, particularly on the within-person level.
Secondly, we asked about the subjectively perceived opportunities for participation in teacher training, which may of course differ from the opportunities for influence actually granted.Future studies could, for example, also include the perspective of other people involved in teacher training, such as mentors or instructors.This would at least provide the opportunity to incorporate another perspective and triangulate situational perceptions.Valid information about what actually takes place in teacher training would probably require observational methods, which, however, given the length and complexity of the training (e.g., various training locations), is rather unrealistic in research practice.
Thirdly, it is important to address the reliability values of the CFA for perceived participation opportunities at the within-person level.While the reliability coefficient omega (ω within = 0.61) may not reach optimal levels, literature provides support for the acceptability of moderate reliability.For example, Yang et al. (2022) suggest that reliability values ranging from 0.50 to 0.70 may be acceptable in specific contexts, such as scales with fewer items or studies focusing on within-and between-person variations (e.g., Fisher et al. 2016;Fleeson 2001), which reflects our specific study context.Similarly, Shrout (1998) proposed a range of 0.61-0.80 to indicate moderate reliability.The author implies that moderately reliable measures may introduce some bias when used as explanatory variables in regression analyses; however, the adverse effects are relatively limited.To assess the robustness of the results in the face of this alteration of the models, we conducted additional analyses by using the four individual items of perceived participation separately, resulting in a total of 64 models.Overall, there are no major changes compared to the original 16 models that include the aggregated participation scale.With respect to intraindividual differences in intraindividual effects (within-level moderation) the same applies as significant interaction effects are observed predominantly for the same emotions, with only minor deviations in two specific effects: (1) In weeks in which trainee teachers perceive fewer opportunities for participation in regard to organization of work, above-average intrinsic motivation compensates for the perception of anger and (2) trainee teachers who report aboveaverage extrinsic motivation in a given week, the positive effect of perceived participation in regard to content definition on pride is weaker, meaning that trainee teachers are less proud.However, as the overall representation remained largely consistent and the reliability coefficient omega at the between-person level was good (ω between = 0.91), we sticked to our perceived participation scale.
Finally, it must be acknowledged that the sample might be selective due to the voluntary nature of the survey.It cannot be ruled out that, for instance, trainee teachers might feel particularly positive during a specific week or may wish to express frustrations.Challenges associated with potential sample selection biases (person-related confounders) and potential context-related confounders, however, are more or less normal and acceptable in field studies like ours when prioritizing realistic field conditions.Another approach would involve conducting controlled experimental studies, which, although they may help mitigate person-related and context-related confounders under specific conditions, often sacrifice external validity.

Conclusions
Even though our study has some limitations as described, empirical evidence emerges supporting our formulated hypotheses.Our models have shown that the within-person perspective plays a central and non-negligible role in finding empirical evidence for CVT.We therefore also encourage future researchers to extend their analyses beyond the between-person perspective and include the within-person level in order to achieve more meaningful results with regard to emotional-motivational aspects (see also Pekrun 2021).Summing up and given the assumption that emotional states can be interpreted as an essential parameter for assessing the fit between the person and the environment (Sembill et al. 2007), the interaction effects found can be

On the one hand, intrinsic motivation moderates the relationship of perceived participation and four emotional states, namely enjoyment (Model 1a: b = −0.050,p = 0.043), hope (Model 1b: b = −0.068,p = 0.014), anxiety (Model 1e: b = 0.084, p = 0.023) and hopelessness (Model 1g: b = 0.123, p < 0.001).In regard to the former two emotional states, representing positive emotional experiences, the effect is negative.Whereas for the latter two (negative) emotional states the effects are positive.On the other hand, extrinsic motivation represents a moderator on the within-person level in the relationship of perceived participation and anger (Model 2d: b = −0.076,p = 0.036) as well as perceived participation and hopelessness (Model 2g: b = −0.111,p = 0.006).Both effects are negative.All significant interaction effects identified are depicted in Fig.4.The linear growth trajectories of weekly intrinsic motivation, which were person-mean centered (refer to Fig.4, models 1a, 1b, 1e and 1g) and their respective deviations of plus/minus one (scale) unit, as well as the person-mean centered weekly extrinsic motivation (refer to Fig.4, models 2d and 2g) with corresponding deviations of plus/minus one (scale) unit, are illustrated in the graphical representations.
