Figure 4: The relationship between the subjective knowledge gain or the overall evaluated quality of courses and participation-related items in theoretical and practical teaching in the traditional curriculum and the reformed curriculum HeiCuMed. The scatter plots represent the bivariate distribution of the evaluation means of the specified item in the module seminars (purple rings) and practical sessions (green rings) under HeiCuMed and in the lectures (purple dots) and practical sessions (green dots) of the traditional curriculum. The means and standard deviations of the predictor evaluations (Ø) and the corresponding regression line, regression coefficients (a) and adjusted correlation coefficients (r) are given in the corresponding colours. The predictors (x-axis) and their average values in Ba and Bb, Ca and Cb are the same. (Sem) Seminar, (Pract) practical session, (Lect) lecture, (***) p≤0.001.
