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.

q3 i2 Teachers using mastery learning felt better about teaching (effect size = .61) and accepted greater responsibility (effect size = 1.29), but expressed somewhat less confidence in their teaching abilities (effect size = -.59). → Guskey 1985

Evidence

Guskey 1985

q3 · i2 · quant-synthesis · r2

Large-scale study by Guskey (1984) involving 117 junior and high school level teachers; the printed effect sizes of .61, 1.29, and -.59 are each a printed effect size with its value, showing mixed effects including the reduced confidence the authors call a "humbling effect."

"Guskey-(1984) found that teachers who use -mastery learning and see improvement in. 'student learning outcomes begin to feel much betterabout' teaching and their roles as teachers (effect size = .61), accept far greater personal responsibility for their students' learning successes and failures (effect size = 1,29), but express somewhat less confidence in their teaching abilities (effect size = -.59)."
