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.

q2 i2 Across 62 courses and N = 6542 students, interactive engagement courses' average normalized gains were about two standard deviations greater than traditional courses', and the correlation of average gains with pretest scores was +0.02. → Lei Bao 2007

The article reports (Introduction) Hake's large multi-course survey as background: 48 interactive-engagement courses versus 14 traditional courses, with the IE courses' average normalized gains 'about two-standard deviations greater' and a +0.02 correlation of gains with pretest scores across all courses.

"In his experiment with 62 courses and N = 6542 students [1c], Hake observed that, on average, 48 courses employing “interactive engagement” types of instruction achieved average normalized gains about two-standard deviations greater than 14 courses subjected to “traditional” instruction."
