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.

q1 i? Reducing cognitive load does not always enhance learning; it can sometimes impair it. → Schnotz 2007

Evidence¶

Schnotz 2007¶

Schnotz, W., Kürschner, C. (2007). A Reconsideration of Cognitive Load Theory. Educational Psychology Review 19, 469–508. https://doi.org/10.1007/s10648-007-9053-4

q1 · i? · theoretical · r2

Theoretical argument in the article's abstract: the authors analyze the conceptual distinctions between kinds of cognitive load and conclude that "reduction of cognitive load can sometimes impair learning rather than enhancing it". No empirical data are reported in the available text.

"It emphasizes that reduction of cognitive load can sometimes impair learning rather than enhancing it."

Discussion¶

Learner Variables¶

Working Memory — predictor: learners who differ on it differ in outcomes

Instructional guidance that helps novices can become redundant or counterproductive as expertise grows. — the general claim this finding bears on, with the studies behind it
Cognitive Load Reduction Improves Learning — reports the opposite
Redundant on-screen text impairs learning when it competes with a visualization, though written text duplicating narration alone can help — related
Interesting but irrelevant details can impair comprehension and transfer, with effects that vary with the material and the learner — related
Split Attention Effect Degrades Learning — reports the opposite
Germane cognitive load is reformulated as redistributing working memory resources from extraneous to intrinsic processing rather than adding to total load — related
Effective intervention timing in AI-based instruction does not always mean immediate response; the interval between student difficulty and teacher intervention can allow independent problem solving — related
Oral non-interactive teaching can enhance learning more than written teaching for complex materials — related
Instruction based on cognitive load theory can compensate for age-related cognitive declines — related
