Explanation for dropouts
weakness
One source of weakness in this study is the relatively large number of dropouts with small sampling size. The rigid timetable may have contributed to participants dropping out. Presumptively, a larger number of students fell behind the schedule than those who contacted the supervision. It is conceivable that the withdrawal from the study and the minimal time commitment share a common cause. We hypothesise that MC-Duell did not intrinsically motivate students in the long term to engage with the learning programme.
