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.

q2 i? After controlling for pre-test scores, the experimental group scored significantly higher than the control group on the Scientific Attitude Scale (F = 5.660, p < .05). → Lai 2016

Lai 2016

Lai, C. (2016). Third graders' understanding of air concepts facilitated by the iPod inquiry teaching method. International Journal of Research in Education and Science (IJRES), 2(1), 1-9. https://eric.ed.gov/?id=EJ1105183

q2 · i? · causal · r2

ANCOVA on the same quasi-experiment (53 vs 53 students), pre-test as covariance, on a 40-item four-point Likert Scientific Attitude Scale (total Cronbach's α = .93). Post-test means were 143.89 (SD 12.04) versus 139.55 (SD 21.88).

"the performance of the students in the experimental group in the Scientific Attitude Scale was significantly higher than that of the control group ( F=5.660, p<.05)"
