Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? Problem solving was superior to example study on one-week delayed posttest performance, but not on immediate performance, supporting a desirable-difficulties approach. → Katharina Scheiter 2026
Evidence¶
Katharina Scheiter 2026¶
Katharina Scheiter, Alexander Renkl. (2026). On the challenges of investigating lasting learning: A commentary. Learning and Instruction 105 (2026) 102417. https://doi.org/10.1016/j.learninstruc.2026.102417
q2 · i? · theoretical · r3
The commentary reports a study comparing problem solving with example study after initial acquisition; the delayed advantage held "regarding one-week delayed posttest performance, but not for performance assessed immediately after learning". No effect size is printed in this passage.
"Ruitenburg et al. (2025) showed that problem solving was superior to example study regarding one-week delayed posttest performance, but not for performance assessed immediately after learning, thereby again supporting a desirable-difficulties approach (E.L. Bjork & R.A. Bjork & Bjork, 2011)."
Discussion¶
Related Claims¶
- Retrieval practice improves delayed but not immediate performance, consistent with a desirable-difficulties explanation — related
- Micro productive failure (problem solving before instruction) improved sixth-graders' isomorphic algebraic procedural problem solving, with the advantage stable across one-day and one-week delays — related
