Subclaims¶

q3 i? A significant negative fixed effect of the delay indicator (estimate -0.13, p = 0.005) indicates that early planning in complex problem solving is more beneficial than late planning. → Eichmann 2019 q3 i3 The effect of the delay indicator varies by task difficulty (random effect correlation with task easiness r = -0.51): the benefit of early planning is strong in easy tasks and near zero in difficult tasks. → Eichmann 2019 (2)

q3 · i? · associational · r2

GLMM analysis of log data from N = 1346 German students on 21 interactive PISA 2012 CPS tasks found a significant negative fixed effect for the delay indicator (estimate = -0.13, p = 0.005), "indicating that in general it is bene ficial to plan early during the process."

"Research question 2: For the delay indicator, a signi ficant fixed effect and a signi ficant random e ffect was found. The fixed effect of −0.13 indicates that in general it is bene ficial to plan early during the process."

q3 · i3 · associational · r2

Task-dependent random effects in the same GLMM analysis showed the delay effect varied across tasks, with a correlation of r = -0.51 between task easiness and the random effect, "near zero for difficult tasks and negative for easy tasks."

"The correlation between task easiness and the random e ffect of the indicator was r = −0.51. The random e ffect shows that the e ffect of the delay indicator was near zero for difficult tasks and negative for easy tasks."

• The variance of planning time shows no significant fixed effect on CPS performance but a significant task-dependent random effect correlated with task difficulty — related
• Significant interaction effects among duration, delay, and variance indicators show that the effects of planning behaviors on CPS performance are highly intertwined — related
• The duration of the longest planning interval shows no significant fixed effect on CPS performance but a significant task-dependent random effect — related
• Models including task-dependent random effects fit CPS log data better than models with only fixed effects for all three planning indicators — related
