Subclaims¶

q2 i? SBI students with MD-PS rated diagrams (M = 3.16) and the problem-solving procedure (M = 2.59) favorably on the TARF-R. → Jitendra 2017 q2 i? Treatment teachers reported high satisfaction with the SBI intervention overall (total M = 3.34) and with the diagrams in particular (M = 3.54). → Jitendra 2017 (2)

Evidence¶

Jitendra 2017¶

Jitendra, A. K., Harwell, M. R., Dupuis, D. N., & Karl, S. R. (2017). A randomized trial of the effects of schema-based instruction on proportional problem solving for students with mathematics problem-solving difficulties. Journal of Learning Disabilities. https://doi.org/10.1177/0022219416629646

q2 · i? · causal · r2

Descriptive acceptability results from a modified TARF-R completed by SBI students at the end of the study (coefficient alpha 0.83), rated on a 1-to-4 scale. These are descriptive means with no significance test or effect size reported.

"The mean score for SBI students with MD-PS was 3.16 (SD = 0.66) on diagrams and 2.59 (SD = 0.58) on the problem-solving procedure. On the multiple solution strategies item, the mean score was 2.95 (SD = 0.98)"

q2 · i? · associational · r1

Descriptive results from the 22-item Teacher Satisfaction Survey completed by treatment teachers at the end of the study (coefficient alpha 0.92), on a 0-to-4 scale. Descriptive means only; no significance test or effect size was reported.

"The mean scores were 3.34 (SD = 0.35) for the total score, 3.41 (SD = 0.42) for the overall benefits of the SBI intervention, 3.54 (SD = 0.42) for diagrams, and 3.12 (SD = 0.47) for problem solving procedures."
