q4 i? An ancillary longitudinal analysis of PPS data showed the SBI group demonstrated significantly more growth in proportional problem solving than controls. → Jitendra 2015

Evidence¶

Jitendra 2015¶

Jitendra, A. K., Harwell, M. R., Dupuis, D. N., Karl, S. R., Lein, A. E., Simonson, G., & Slater, S. C. (2015). Effects of a research-based intervention to improve seventh-grade students’ proportional problem solving: A cluster randomized trial.

q4 · i? · causal · r3

An ancillary analysis of PPS longitudinal data explored "student change over time and whether such change was impacted by the treatment", finding the SBI group "showed significantly more growth in proportional problem solving" than the control group.

"also showed significantly more growth in proportional problem solving"

Discussion¶

Learner Variables¶

• Problem Solving — outcome: instruction changes it
