Evaluation results
During the pilot phase, students voluntarily attending a bPbL group appeared to be significantly less sceptical about CbL compared to students who did not choose the bPbL approach (not shown). In the randomised main study, however, we found no difference between students having attended bPbL or cPbL groups with respect to the evaluation of CbL scepticism, familiarity with the Internet platform ILIAS, and satisfaction with the course (Fig. Evaluation data of the scales “sceptical about computer-based learning” (CbL), “familiar with the online platform ILIAS” and “satisfied with the course”. For every item, a Likert scale from 1 (= true) to 5 (= not true) was used. Items underlying a respective scale were averaged. Resulting scores from students attending conventional or blended problem-based learning (cPbL or bPbL) are shown as boxplots depicting median, 25th and 75th percentiles.
