q2 · i? · causal · r1

Extreme-groups comparison of high versus low CPC students in the retention study class on the delayed posttest. The article reports a significant difference favoring high CPC students with means of 8.38 and 7.76, on the delayed posttest only.

"The performances of the high CPC students were found to be superior to those of the low CPC students on thee delayed posttest only, t (85) = 1.7,3, P < .05, with mean scores of 8.38 and 7.76, respectively."

Discussion¶

Related Claims¶

• 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
• Retention after learning with the chunking method is high, with 85% to 95% of original learning retained over three months — related
• The correlation between cognitive processing capacity and test performance is non-significant when using the chunking method — reports the opposite
• CBI subjects outperform print subjects on the delayed posttest only
