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? Mean test performance did not significantly differ between text-with-image and text-only conditions in Study 1a or Study 2. → Jaeger 2024 q3 i? Test relative accuracy did not significantly differ between conditions in either study; explain relative accuracy showed only a marginal difference favouring text-only in Study 1a (p = 0.06) and none in Study 2. Non-significant differences do not show that visuals had no effect. → Jaeger 2024 (2)

q3 · i? · causal · r2

Study 1a online experiment with 163 undergraduates reading biology texts. Test performance did not significantly differ between conditions (non-significant tests, not a test of equivalence): "t(161) = 0.07, p = 0.95, d = 0.01". Study 2 similarly found no difference, t(46) = 0.21, p = 0.84, d = 0.06.

"mean test performance did not significantly differ between the text-with-image and text-only conditions, t(161) = 0.07, p = 0.95, d = 0.01."

q3 · i? · causal · r2

Study 1a: test relative accuracy did not differ between conditions; explain relative accuracy showed only a marginal difference with text-only tending higher. Study 2 found no differences for either test or explain relative accuracy (all p > 0.6).

"there was no difference in test relative accuracy between the two groups, t(139) = 1.59, p = 0.12, d = 0.27. There was a marginal difference in explain relative accuracy, t(156) = 1.87, p = 0.06, d = 0.30."
