Subclaims¶

q2 i? Immediate drop curves showed higher accuracy on unique problems than immediate peak, close multiple spikes and separated multiple spikes curves. → Inge Molenaar 2021 q2 i? All curve forms differed significantly from each other in accuracy on problem solving attempts, with accuracy declining as curve complexity increased. → Inge Molenaar 2021 (2)

Evidence¶

Inge Molenaar 2021¶

Inge Molenaar, Anne Horvers, Ryan S. Baker. (2021). What can moment-by-moment learning curves tell about students' self-regulated learning? Learning and Instruction, 72, 101206. https://doi.org/10.1016/j.learninstruc.2019.05.003

q2 · i? · associational · r2

Linear mixed model on accuracy of unique problems (Table 8, N = 265 graphs, 92 students) with post-hoc pairwise comparisons. The intercept for immediate drop was 0.92, and the article reports "Immediate drop showed higher accuracy than the other curves" with the printed t statistics above.

"Immediate drop showed higher accuracy than the other curves (immediate peak t(209.15) = 5.03, p < 0.001, close multiple spikes t(193.66) = 5.73, p < 0.001, separate multiple spikes t(205.05) = 4.94, p < 0.001)."

q2 · i? · associational · r2

Second linear mixed model on accuracy of problem solving attempts (Table 9) with all pairwise contrasts significant (Table 10, e.g. immediate drop versus separated multiple spike t(239.75) = 7.06). The article describes "a downward trend in accuracy as curve complexity increased".

"All curves differed significantly from each other with respect to accuracy on problem solving attempts, with a downward trend in accuracy as curve complexity increased, see Table 10."

Discussion¶

Related Claims¶

• Close multiple spikes suggest students unable to regulate accuracy on their own learned better once the ALT took over part of the regulation. — related
• Four visual patterns of moment-by-moment learning curves occur in grade-five arithmetic practice with an ALT, with immediate peaks most frequent and single spikes absent. — related
• Transfer score was significantly predicted by the count of moment-by-moment learning curve forms, with separated multiple spikes negatively impacting transfer. — related
• Students learned significantly over the four lessons, and learning outcomes differed by curve form: immediate drop reflected high prior knowledge with low gain, while immediate peak showed the highest gain. — related
• The form of moment-by-moment learning curves depends on problem difficulty: immediate drops concentrate on easy problems, while spike forms become more frequent as difficulty increases. — related
• Effort (unique problems and problem-solving attempts) does not differ between moment-by-moment learning curve forms. — related
