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? In the clutch study, both groups reached similar performance levels despite the GCL difference. → Melina Klepsch 2020
q2 i? In the time-zones study, task performance did not differ between fluent and disfluent conditions. → Melina Klepsch 2020 (2)
Evidence¶
Melina Klepsch 2020¶
Melina Klepsch, Tina Seufert. (2020). Understanding instructional design effects by differentiated measurement of intrinsic, extraneous, and germane cognitive load. Instructional Science (2020) 48:45–77. https://doi.org/10.1007/s11251-020-09502-9
q2 · i? · causal · r1
Post-test performance in the clutch study (N = 31), measured with 14 questions worth at most 39 points, analyzed with prior knowledge and FAM subscales as covariates. No significant main effect of the imagination instruction was found.
"For task performance, we found no main effect (F < 1, n.s.): Both groups reached similar performance levels."

q2 · i? · causal · r2
Post-test performance in the time-zones study (N = 36), a 17-question test worth at most 34 points, with prior knowledge as covariate. No significant difference between fluent and disfluent conditions; equivalence was not tested.
"For task performance, we found no main effect (F (1,33) = 1.65, p = 0.21, η2 = 0.05): Both groups reached similar performance levels."
