Subclaims¶

q3 i? No significant fixed effect of the duration of the longest interval between interactions was found on the probability of success in CPS (estimate = -0.05, p = 0.639). → Eichmann 2019 q3 i? A significant random effect for the duration indicator was found, with a correlation between task easiness and the random effect of r = -0.04, indicating the effect varies between tasks but is unrelated to task difficulty. → Eichmann 2019

q3 · i? · associational · r2

GLMM analysis of log data from N = 1346 German students on 21 interactive PISA 2012 CPS tasks found no significant fixed effect for the duration indicator (estimate = -0.05, p = 0.639) but a significant random effect with correlation r = -0.04 with task easiness, showing the effect "varies between tasks but is not related to task di fficulty."

"The correlation between task easiness and the random e ffect of the indicator was r = −0.04. The random e ffect shows that the duration of the longest interval varies between tasks but is not related to task di fficulty."

Discussion¶

Related Claims¶

• 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
• Models including task-dependent random effects fit CPS log data better than models with only fixed effects for all three planning indicators — a broader claim this one bears on
• Early planning in complex problem solving is generally beneficial, with a significant negative fixed effect of the delay indicator — related
