Effects of mastery learning programs on student attitudes.

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.

q4 i2 Students rated the instruction more positively in 16 of 18 studies (mean ES 0.63) and held more positive attitudes toward the subject in 12 of 14 (mean ES 0.40). → Kulik et al. 1990

Evidence

Kulik et al. 1990

Kulik, C.-L. C., Kulik, J. A., & Bangert-Drowns, R. L. (1990). Effectiveness of Mastery Learning Programs: A Meta-Analysis. Review of Educational Research, 60(2), 265–299. doi:10.3102/00346543060002265

q4 · meta-analysis (18 and 14 studies of attitudes) · i2 · medium effect, ES = 0.63 toward instruction, 0.40 toward subject · n=18 studies · quant-synthesis · r?

Eighteen evaluations measured students' ratings of the instructional method: 16 favoured the mastery class, with a mean effect of 0.63 SD. Fourteen measured attitudes toward the subject being taught: 12 favoured the mastery class, with a mean effect of 0.40 SD.

"Overall, the average effect size in the 18 studies was 0.63, t(17) = 4.50, p < .001."

Studies bearing on this claim

How do students and teachers respond to it? This table gathers the studies behind this claim and the 2 narrower claims that bear on it: 2 distinct studies (2 quant-synthesis), q3–q4, 2 of 2 with an effect size coded. One row per study, codes as each entry records them; no effect is averaged and no verdict is drawn. Built by scripts/synthesize_claim.py from eval/synthesis/; a row that looks wrong is fixed on the claim it comes from.

Discussion

Attitude scales were self-report and the studies were mostly college PSI courses, so this says students like the method, not that it raises motivation more broadly. It sits alongside a small cost in instructional time: in six of eight studies mastery students needed more, a median 4% more.
