Figure 2. The relationship between the subjective knowledge gain (“Gained important knowledge”) and the items relating to didactics in the traditional and the reformed curriculum HeiCuMed. The scatter plots represent the bivariate distribution of the evaluation means of the specified items in the traditional curriculum (20 points, red) and HeiCuMed modules (50 points, black). The corresponding extrapolated regression lines, regression coefficients (a) and adjusted correlation coefficients (r) for the traditional curriculum (old) and HeiCuMed (new) are given in the corresponding colours.
