Effects of COVID-19 Pandemic on Progress Test Performance in German-Speaking Countries

Figure 2

Results of the linear mixed model described in the article for each of the three PT pairs considered. Every PT shares a considerable number of questions with the PT that took place five semesters before; tests were conducted at nine different German and Austrian faculties. In these graphics, test modalities are fixed by their weighted estimates. The x-axis represents the semesters, while the achieved relative scores are shown on the y-axis. The dashed line represents the most recent test in each pair (41 = winter semester 2019/20, 42 = summer semester 2020, and 43 = winter semester 2020/21); the gray areas are the respective 95% confidence intervals. The difference in mean scores for students in earlier semesters (36 = summer semester 2017; 37 = winter semester 2017/18; 38 = summer semester 2018) increases with every successive pair, while the results of the pair PT37-PT42 seem to equally improve throughout all semesters; the scores of the other two pairs converge with increasing semesters.
