First, the characteristics of the sample are described. The total number of students investigated was 93 in the intervention group and 396 in the baseline group. The students’ mean age in the intervention group was M = 13.8 years (SD = 0.571) and M = 13.99 years (SD = 0.585) in the baseline group. The groups were also compared according to their last marks in physics. The Austrian system uses marks from 1 to 5, 1 stands for excellent and 5 for fail. The average mark in physics was M = 2.15 (SD = 0.988) in the intervention group and M = 2.23 (SD = 1.077) in the baseline group. A Mann-Whintey U-Test was performed which shows no significant difference (sig = 0.618) between the groups at a 0.05 significance level.

At first, the hypothesis was tested whether the intervention group could improve their conceptual understanding of key-ideas of geometrical optics (Research Question I). Results of the pre- post-gains of the intervention group are displayed in Fig. 1.
