Subclaims¶

q2 i? Challenge based lessons scored significantly higher than NGSS practices-aligned lessons on real-world engagement, critical secondary research, and effective communication, with score differences the report prints as between 0.81 and 1.75 standard deviation units. → Iwatani 2020 q2 i? Challenge based lessons were rated equivalent to NGSS practices-aligned lessons on self-direction, practicing science and engineering, and substantive collaboration. → Iwatani 2020 (2)

Evidence¶

Iwatani 2020¶

Iwatani, E., Means, B., Romero, M. R., & Vang, M. C. (2020). Deepening Science Engagement with Challenge Based Learning: Research Report. San Mateo, CA: Digital Promise. https://digitalpromise.dspacedirect.org/items/f928a607-e645-49d6-abbf-3d9b42cf7383 doi:10.51388/20.500.12265/93

q2 · i? · design · r3

Independent rubric scoring compared challenge based lessons to NGSS practices-aligned lessons collected at baseline. Where challenge based lessons scored higher, the report prints differences "between 0.81 to 1.75 standard deviation units", a large difference in this rubric-scored comparison.

"Where challenge based lessons scored higher, they score higher by quite a lot (between 0.81 to 1.75 standard deviation units)."

q2 · i? · design · r2

Independent rubric scoring of lessons by scorers blind to lesson type. Challenge based lessons were rated "significantly higher in three of the six deeper learning dimensions" and equivalent on the remaining three; no effect size is printed for the equivalence finding.

"Relative to NGSS practices-aligned lessons, the challenge based lesson scores were rated significantly higher in three of the six deeper learning dimensions (real-world engagement, critical secondary research, and effective communication) and equivalent in the remaining three areas."
