q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? In four edX MOOCs analyzed across 6.9 million video-watching sessions, median engagement was near 100% for videos under 6 minutes, about 50% for 9- to 12-minute videos, and about 20% for 12- to 40-minute videos. → Brame Cynthia J 2016

The essay reports, citing Guo et al. (2014), an observational analysis of video-watching sessions in four edX MOOCs. "the median engagement time for videos less than 6 minutes long was close to 100%". The essay adds that median engagement was ~50% for 9- to 12-minute videos and ~20% for 12- to 40-minute videos.
"They observed that the median engagement time for videos less than 6 minutes long was close to 100%–that is, students tended to watch the whole video (although there are significant outliers; see the paper for more complete information)."
Discussion¶
Related Claims¶
- Segmenting video into short pieces or click-forward pauses supports student engagement and learning from video — the general claim this finding bears on, with the studies behind it
- No dose-response effect: video benefits do not systematically increase with intervention length — related
- MOOC video engagement declines with video length, with median engagement under half the duration for videos longer than nine minutes — possibly the same claim (merge candidate)
- A University of Pennsylvania study found only about half of MOOC registrants viewed a lecture and only about four percent finished a course entirely — related
- Guo et al. found engagement depends on video production style: short videos, talking heads on slides, Khan-style drawing more engaging than slides or coding, classroom recording weak online — related
- A review of music education asserts that MOOC completion is typically under 10% and that embodied musical learning resists short video lectures and self-graded quizzes — related
- mLearning students prefer video-based materials with each video under 5 minutes — related
- Students pause the video after a few sequences to consult a segment menu and judge workload by segment count — related
- Viewing of the personalized AI videos declined sharply across the quarter, with views of the first week-9 video set suggesting fewer than 10% of the course population was watching voluntarily by the end of the course — related
