Subclaims¶

q2 i? Treatment scored higher than control on posttest searching exercise multiple choice (t(132) = 3.35, p = .001), but the measure had low internal consistency (α = .37). → Goetz 2015 q2 i? On question 1 about keyword selection, 86% of treatment versus 54% of control responded correctly (χ2(1) = 13.04, p < .001). → Goetz 2015 (2)

q2 · i? · causal · r2

Independent-groups t test on the six-item posttest multiple-choice measure in the quasi-experimental study; means were 3.83 (treatment, N=42) vs 2.93 (control, N=92). The article notes the measure's low reliability made it "an unstable estimate of student performance".

"Independent t tests revealed a significant difference between treatment and control groups in terms of their posttest searching exercise multiple choice scores, t (132) = 3.35, p = .001 (see Table 1). However, as noted above, the low internal consistency of this measure made it an unstable estimate of student performance."

q2 · i? · causal · r2

Chi-square item analyses of the posttest multiple choice in the same study; only the keyword-selection question differentiated the groups, with treatment at 86% correct versus control at 54% correct.

"of six chi -square analyses comparing the percentages of correct responses, only the analysis of question 1 (about keyword selection) showed a significant difference between the treatment group (86% correct) and the control group (54% correct): χ2(1) = 13.04, p < .001."
