q3 i? The direct effect of worked examples on post-test knowledge or learning gains was not moderated by prior knowledge or WMC, and no interaction with self-explanation quality was significant. → Bichler 2022

Evidence¶

Bichler 2022¶

Bichler, S., Stadler, M., Bühner, M., Greiff, S., & Fischer, F. (2022). Learning to solve ill-defined statistics problems: does self-explanation quality mediate the worked example effect? Instructional Science. https://doi.org/10.1007/s11251-022-09579-4

q3 · i? · causal · r2

In the conditional process model with prior knowledge as moderator (N = 74), the treatment × prior knowledge interaction was non-significant. Likewise, in the WMC model the direct effect was not moderated by WMC (b = −0.35, p = .428). The article reports no evidence for prior knowledge and WMC moderating the worked example effect.

"The direct effect of worked examples on post-test knowledge was not moderated by prior knowledge b = −0.02, pone-tailed = .473, 95% CIboot [−0.62, 0.43]."
