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.
q3 i? Participants in the Diagram condition reported higher extraneous load than participants in the Arithmetic, Text + Arithmetic, and Diagram + Arithmetic conditions. → Bas Kolloffel 2009

q3 · i? · causal · r2
Self-report cognitive load questionnaire (9-point Likert scales, six items) administered after each section in the five-condition experiment. The article reports "higher levels of extraneous load" in the Diagram condition; no effect size was printed.
"Differences between conditions with regard to extraneous load were observed as well, F(4,118) = 2.89, P\ .05. Participants in the Diagram condition experienced higher levels of extraneous load compared to participants in the Arithmetic condition ( P\ .01), the Text + Arithmetic condition ( P\ .01), and the Diagram + Arithmetic condition (P\ .01)."
Discussion¶
Learner Variables¶
- Working Memory — outcome: instruction changes it
Related Claims¶
- Adding equations to tree diagrams reduced cognitive load but did not improve learning outcomes — related
- Learners working with tree diagrams performed fewer manipulations in the simulations than learners in other conditions — related
- In inquiry learning of combinatorics, learners given a Text + Arithmetic representation outperformed learners given tree diagrams on total post-test scores — related
- Reducing extraneous load can also remove affordances for germane processes — related
