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 i? Challenge based lessons scored significantly higher than typical lessons on real-world engagement, self-direction, science and engineering practice, critical research, collaboration, and communication opportunity dimensions. → Iwatani 2020

q2 · i? · design · r3

Rubric-based scoring of 71 lesson samples by independent scorers who were blind to lesson type. Challenge based lessons outperformed typical lessons on all six deeper learning opportunity dimensions, though no effect sizes are printed in the available text.

"On average, relative to typical lessons, challenge based science lessons substantially provided more opportunities for: real-world engagement, self-direction, practice of science and engineering skills, conducting critical research, substantive collaboration, and effective communication."
