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 i2 Posttest performance was significantly higher than pretest performance (d = 0.42), indicating learning happened. → Hu 2024
Evidence¶
Hu 2024¶
Hu, Y., Wouters, P., van der Schaaf, M., & Kester, L. (2024). The effects of achievement goal instructions in game-based learning on students' achievement goals, performance, and achievement emotions. Learning and Instruction, 93, 101943. https://doi.org/10.1016/j.learninstruc.2024.101943
q3 · i2 · causal · r2
Paired t-test across all 450 participants comparing pretest and posttest knowledge scores in the CosmiClean chemistry game session showed a significant gain, "t = 8.19, df = 449, p < 0.001, d = 0.42".
"A paired t-test shows that there was a statistically significant difference between pretest performance and posttest performance (t = 8.19, df = 449, p < 0.001, d = 0.42), so, learning happened."
Discussion¶
Related Claims¶
- Students showed significant content-knowledge gains from pre-test to post-test after the Digital World level — possibly the same claim (merge candidate)
- Non-traditional letter writing improved 9th graders' conceptual understanding of a chemistry mixture unit more than traditional writing, with a small effect — related
