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.
q3 i? A significant negative treatment × pretest proportional reasoning interaction indicated treatment students with poorer pretest proportional reasoning benefited more, gaining more probabilistic reasoning at posttest. → Begolli 2021
Evidence¶
Begolli 2021¶
Begolli, K. N., Dai, T., McGinn, K. M., & Booth, J. L. (2021). Could probability be out of proportion? Self-explanation and example-based practice help students with lower proportional reasoning skills learn probability. Instructional Science. https://doi.org/10.1007/s11251-021-09550-9
q3 · i? · causal · r2
Regression interaction from the same cluster-randomized classroom experiment (Model 4, N = 220). The printed coefficient was "bTreatment x PR Pretest = − 0.34, SE = 0.15, t = − 2.34, p = 0.044", plotted in Fig. 4 with 95% confidence interval bars.
"the significant interaction between treatment and pretest Proportional Reasoning scores (bTreatment x PR Pretest = − 0.34, SE = 0.15, t = − 2.34, p = 0.044) had a small negative influence on posttest Probabilistic Reasoning scores, indicating that the treatment participants with poorer pretest Proportional Reasoning scores actually benefited more from the treatment"
Discussion¶
Related Claims¶
- Prior proportional reasoning knowledge predicts later probabilistic knowledge even after controlling for prior probability knowledge
- Students using a worked-example revised probability textbook improved more in probabilistic reasoning than students using the standard textbook — related
