Subclaims¶

q3 i? An ANOVA on total coverage showed a main effect of condition, F(2,62) = 6.49, p = 0.003; the 2-demo tutorial's total coverage was lower than the control's (p = 0.001) and the review tutorial's (p = 0.041), while control and review did not differ (p = 0.149). → Hans van der Meij 2018

q3 · i? · causal · r2

ANOVA on log-based total coverage (mean 70.2%) across the three conditions of 65 elementary students. Post hoc Tukey LSD contrasts showed the 2-demo tutorial had lower total coverage than both the control and review tutorials; control and review did not differ.

"An ANOVA showed a main effect of condition, F(2,62) = 6.49, p = 0.003. Post hoc analyses revealed that total coverage for the 2-demo tutorial was lower than for the control ( p = 0.001), and the review tutorial (p = 0.041)."

Discussion¶

Related Claims¶

• Video coverage declined significantly after the preview, and reviews were viewed more fully than second demonstrations — related
• Video tutorials produced large learning gains from pre-test to training test, with significant decline at later post-tests and no condition effect — related
• Adding reviews or a second demonstration did not significantly improve self-efficacy or learning over the control condition — related
