Subclaims¶

q3 i? Regressing scores by Bloom-taxonomy level, the video-group coefficient was significant for Level-2 understanding (9.06, p < 0.05) and Level-4 analyzing (16.58, p < 0.1), but not for Level-1 remembering or Level-3 applying. → Jose J. Vazquez & Eric P. Chiang 2016

q3 · i? · causal · r2

OLS regressions by cognitive domain level (n = 82), classifying all assessment questions using Anderson and Krathwohl's updated Bloom taxonomy. Group coefficients: Level-1 5.73 (ns), Level-2 9.06** (p < 0.05), Level-3 1.60 (ns), Level-4 16.58* (p < 0.1).

"The results suggest that the marginal benefit from multimedia lectures was highest, and most statistically significant, for levels 2 and 4; understanding and analyzing, respectively. In fact, students in the video group scored 16 points higher on questions in level 4."

Related Claims¶

• Students given multimedia pre-lectures scored almost 6 points higher than textbook-only students on an immediate assessment of economics concepts — a broader claim this one bears on
• The video-group advantage grew to almost 8 points on a retention assessment taken two weeks later — related
• Most student–AI interactions occur at the understand and apply Bloom levels, with analyze appearing rarely — related
• Questions interpolated between video lecture segments improve subsequent test performance and reduce mind wandering — related
