Table 7 Empirical results for Swiss anchor task (1.1) processing a customer order (% correct)

From: Challenges of a cross-national computer-based test adaptation

  Step 5: Think-alouds with apprentices (N = 9)a Step 6: Pilot study with apprentices (N = 54) Time 1 main study (ALUSIM test) (N = 1756)b Time 2 main study (LINCA test) (N = 1365)c
Identify correct customer ID (item 1) 100 63.0 83.8 76.2
Identify correct amount of product/item (item 3) 100 85.2 90.8 91.4
Identify correct article number (item 4) 100 81.5 89.3 91.8
Identify correct customer specific price per item (item 5) 33.3 25.9 52.7 No equivalent item in LINCA
  1. aFour apprentices worked alone; the remaining apprentices worked in groups of two or three
  2. bAfter the adaptation study the three adapted anchor-tasks of ALUSIM were implemented in 85 classes in the E-profile and M-profile from November to December 2012 in Switzerland. Although we do not discuss the findings in detail, we present the results as a reference
  3. cAfter finishing the adaptation study LINCA developed and implemented tasks that were similar to ALUSIM but structured for Swiss conditions and embedded in Swiss work-life situations, e.g., ‘processing a customer order’. Nevertheless, we can only compare some items and have to be careful with the interpretation. Chi2 tests for item 1, 3 and 4 between t1 and t2 showed no statistically significant differences. Although we do not discuss the findings in detail, we present the results as a reference
