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? Coherence showed no significant main effect and linking was marginal (p=.053) on low-level idea-unit recall; the tandem version improved means but not significantly. → Vidal-Abarca 1998
Evidence¶
Vidal-Abarca 1998¶
Vidal-Abarca, E., & Sanjosé, V. (1998). Levels of comprehension of scientific prose: The role of text variables. Learning and Instruction, 8(3), 215-233. https://www.sciencedirect.com/science/article/abs/pii/S0959475297000200
q2 · i? · causal · r2
ANCOVA on recall of the 48 low-level idea units in the same experiment. Means improved only slightly (original 3.36; coherence-plus-linking 5.71) and "differenceswerenotsignificant". No effect size printed, so impact is null.
"Coherence didnotyieldasignificantmaineffect,andlinkingprocedureswereveryclosetotheusual acceptablelevel, F(1,62)=3.902, MSE=7.568, p=.053."
