Veritasium Science Videos: Khan Academy and the Effectiveness of Science Videos
"common view "if only someone could break this down & explain it clearly enough, more students would understand." Khan Academy is great example of this approach w/ clear, concise videos on science. However it is debatable whether they really work. Research has shown these types of videos may be positively received by students. They feel like they are learning & become more confident in answers, but tests reveal they haven't learned anything…apparent reason for discrepancy is misconceptions. Students have existing ideas about scientific phenomena before viewing…If video presents scientific concepts in clear, well illustrated way, students believe they are learning but they do not engage w/ media on deep enough level to realize that what was is presented differs from prior knowledge…hope, however. Presenting students' common misconceptions in video alongside scientific concepts has shown to increase learning by increasing amount of mental effort students expend while watching"
