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? An ANOVA on evaluation scores showed a main effect of problem type and a significant interaction between time of assessment and problem type. → Eva Erdosne Toth 2000

Eva Erdosne Toth, David Klahr, and Zhe Chen. (2000). Bridging Research and Practice: A Cognitively Based Classroom Intervention for Teaching Experimentation Skills to Elementary School Children. Cognition and Instruction, 18(4), 423–459. https://doi.org/10.1207/s1532690xci1804_1

q3 · i? · causal · r1

Repeated-measures ANOVA on the experiment evaluation test (pre and post mean scores on four problem types, N = 71+): main effect of problem type F(3, 210) = 15.2 and time × problem type interaction F(3, 210) = 10.3, both p < .0001; the time main effect was F(1, 70) = 76.5, p < .0001.

"there was also a main effect of problem type, F(3, 210) = 15.2, p < .0001, as well as a significant interaction between time of assessment and problem type, F(3, 210) = 10.3, p < .0001."
