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? Phonological skills, grammatical ability, and working memory showed significant indirect effects on geometric skills through arithmetic skills in fifth graders. → Kleemans 2018
Evidence¶
Kleemans 2018¶
Kleemans, T., Segers, E., & Verhoeven, L. (2018). Role of linguistic skills in fifth-grade mathematics. Journal of Experimental Child Psychology, 167, 404-413. https://doi.org/10.1016/j.jecp.2017.11.012
q3 · i? · associational · r2
Mediation analysis (Process add-on in SPSS, bootstrapping set at 5000 cycles) with 167 fifth graders, arithmetic skills as mediator and geometric skills as outcome, controlling for SES, age, and gender. The article reports "significant" indirect effects and an overall R2 of .40 (p < .001); no standardized effect sizes are printed.
"the total indirect effects of phonological skills ( ab = .390, 95% CI [0.091, 0.813]), grammatical ability (ab = .408, 95% CI [0.101, 0.876]), and working memory ( ab = .473, 95% CI [0.191, 0.889]) via arithmetic skills were significant. The overall R2 of the model was .40 ( p < .001)."
Discussion¶
Learner Variables¶
- Geometric Reasoning — outcome: instruction changes it
