Which features of a mastery learning program, and of the evaluation, go with larger achievement effects.

Subclaims¶

q4 i? In a multiple regression over 103 studies, larger effects went with group-based rather than self-paced programs, higher unit mastery standards, locally developed rather than standardized criterion tests, and comparison groups that received less quiz feedback; social-science courses showed larger effects than mathematics and natural science. → Kulik et al. 1990

Evidence¶

Kulik et al. 1990¶

The authors regressed study effect sizes on program and design features. Group-based programs produced larger effects than self-paced ones; programs with a high unit mastery standard (the percentage correct required before moving on) beat programs with lower standards; effects measured on locally developed tests were larger than on standardized commercial tests (in four studies with both, standardized effects were near zero, from -0.05 to 0.09, against local effects up to 0.64); and effects were smaller where the comparison group received as much quiz feedback as the mastery group. Group-based social-science courses with a high standard averaged 0.89 SD on local tests and 0.76 on standardized ones.

"First, group-based programs produced larger effects than did self-paced ones. Second, programs with a high mastery standard were more effective than programs with lower standards. Third, programs whose effects were measured on locally developed tests produced larger effects than did programs whose effects were measured on standardized, commercial tests. Fourth, effects were larger in studies in which control groups received less quiz feedback than did experimental groups."

Studies bearing on this claim¶

Self-paced or group-paced progression through small units, at what criterion, measured how? This table gathers the studies behind this claim and the 4 narrower claims that bear on it: 6 distinct studies (5 quant-synthesis, 1 causal), q2–q4, 4 of 6 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¶

For design: set a high unit standard and keep the class moving together where possible. For reading the evidence: part of the headline 0.52 SD is the extra quiz feedback mastery students receive, and part is tests written to the course; effects on standardized tests are much smaller.
