Subclaims¶

q3 i? A MANOVA on the 12 attitude items revealed a significant overall difference among the six treatment groups. → Martin 2003 q3 i? The lean program group had the most negative attitudes (21 significant negative comparisons) and the no-practice group the next most (10). → Martin 2003

q3 · i? · causal · r2

MANOVA on the 12-item Likert attitude survey administered after the lesson and posttest showed "F (60, 1188.48) = 12.98, p <.01"; univariate tests were significant on 11 of 12 items. Scheffe summaries showed the lean group with 21 significant negative comparisons and no-practice with 10.

"A MANOVA conducted on the overall attitude data revealed a significant overall difference on the 12 attitude questions, F (60, 1188.48) = 12.98, p <.01. Follow-up univariate analyses indicated significant differences on 11 of the 12 attitude survey items at the p<.01 level."

Discussion¶

Related Claims¶

• Students may be unaware of the absence of objectives: the no-objectives group gave the highest ratings on objective-related attitude items — related
• In one experiment with 256 undergraduates, computer-based lesson versions that included practice produced significantly higher posttest scores than versions without practice — related
• Linguist review of draft items revealed communication problems with terminology and imprecisely reasoned attitude statements — related
• Students notice the absence of practice and examples: attitude items about those events are rated lower when the events are missing — a narrower finding that bears on this claim
