Durability of the achievement effect of mastery learning programs (PSI and LFM), measured on follow-up examinations.

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 In the 11 studies with follow-up examinations, given on average about 8 weeks after instruction, the mean effect was 0.71 SD, against 0.60 at the end of instruction in the same studies; the increase is not significant. → 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 (11 studies with follow-up examinations) · i2 · medium-to-large effect, mean ES = 0.71 SD at follow-up · n=11 studies · quant-synthesis · r?

Eleven of the 108 evaluations in this meta-analysis gave a follow-up or retention examination, on average about eight weeks after instruction ended. Mastery students' advantage was 0.71 SD at follow-up, against 0.60 SD at the end of instruction in the same 11 studies; the authors note the increase is not significant. They conclude the benefits are relatively enduring rather than short-term.

"The average follow-up interval was about 8 weeks in these studies, and the average effect size was 0.71, a strong positive effect."

Studies bearing on this claim

Do the gains last after the course ends? This table gathers the studies behind this claim and the 1 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

Eight weeks is a short horizon for a course-level design, and only 11 of 108 studies measured it. The finding rules out a quick fade, not decay over a year or more.
