A study shows that there is hardly any difference in correctly answered questions when students were divided into two groups that used either live lecture or video lecture. But there were some differences in subjective evaluation: 48% of students preferred live lessons, 27% preferred video lessons and 25% stated ‘neutral’.

On average, the effects are small (about +2 marks) but consistently favour videos. Effects are much larger when videos replace books (+7 marks), or when videos are used to teach skills (+6 marks) instead of knowledge.
