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? Moderator analysis across disciplines shows no significant heterogeneity (p = .554); Biology (1.262), Chemistry (1.022), and Physics (.768) obtained large effect sizes, Environmental Science (.605) medium, and Science and Technology (.304) small. → Funa 2021

q3 · i? · quant-synthesis · r1
Moderator analysis of the 11 pooled studies by scientific discipline. The article reports large effect sizes for Biology (1.262), Chemistry (1.022), and Physics (.768), a medium effect for Environmental Science (.605), a small effect for Science and Technology (.304), and an overall discipline ES of .855 with between-group p = .554.
"The heterogeneity between scientific fields (p > .05) showed no significant effects signifying that PBL as applied to different scientific disciplines may share common effect sizes."
Discussion¶
Related Claims¶
- PBL effect sizes on science achievement do not differ significantly across physics, chemistry, and biology — a narrower finding that bears on this claim
- Science-related subject areas (mathematics, science, medical science) show larger effects than programming technology and other fields — related
- Grade level (JHS vs SHS) does not significantly moderate PBL’s effect on science achievement, though the SHS effect size is descriptively larger — related
- Stratified teaching positively affects all seven studied subjects, with larger effects in English, physics, and geography than in chemistry, biology, and mathematics — related
