Subclaims¶

q2 i1 Students using short CSOs scored significantly higher on 40-item multiple-choice posttests than students using long CSOs, with means separated by 1.50 points. → Furukawa 1978

Evidence¶

Furukawa 1978¶

Furukawa, J. M., Sumpter, K., & Cohen, N. (1978). Chunking Method of Teaching and Studying: II. Paper presented at a meeting of the American Psychological Association, Toronto. https://eric.ed.gov/?id=ED165097

q2 · i1 · causal · r1

Quasi-experimental comparison across two general psychology classes given short versus long CSOs for three chapters each, with counterbalanced order and a 40-item multiple-choice immediate posttest. The article reports a statistically significant difference favoring the short CSO, with mean scores "separated by 1.50 pointé".

"The result, showed a statistically significant difference favoring the short CSO, t (51) = 2.73, E< .01.. The mean scores were separated by 1.50 pointé."

• Chunking reduces working memory load by grouping information into fewer, more meaningful units. — the general claim this finding bears on, with the studies behind it
• In one experiment with 256 undergraduates, computer-based lesson versions that included practice produced significantly higher posttest scores than versions without practice — related
