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.

Related Claims¶
- Visualizing support—provided diagrams or learner-generated drawings—facilitates higher-quality explanations and better comprehension than explaining text alone — related
- Drawing can underperform the generative strategy of explaining, particularly on verbally aligned tests — related
- Visualizer–Verbalizer Questionnaire scores did not predict modality-specific free recall; visual presentation aided recall overall — related
- Diagramming scaffold also improves absolute metacomprehension accuracy for causal relations, extending the effect beyond relative accuracy — related
- Modified film commentaries were consistently superior to the original commentary although differences were not statistically significant at a high level of confidence — related
