Subclaims¶

q3 i? In Study 1, neither the heterogeneity text condition nor the control condition showed a significant pretest-posttest change in school-heterogeneity beliefs. → Baier-Mosch 2026 q1 i? The authors interpret the pattern as showing that experiencing heterogeneity, not merely reading about it, is crucial for changing beliefs. → Baier-Mosch 2026 (2)

Evidence¶

Baier-Mosch 2026¶

Baier-Mosch, Franziska; Dignath, Charlotte; Kunter, Mareike (2026). Effects of heterogeneity simulations on beliefs. Learning and Instruction 101, Art. 102258. https://doi.org/10.1016/j.learninstruc.2025.102258

q3 · i? · causal · r2

Study 1 simple main effects for the comparison conditions: no significant time effect in the "heterogeneity text condition: F (1, 52) =0.012, p =.914, partial η2 =.000" nor in the control condition; no effect sizes were reported for these null findings.

"No other simple main effects were found on the within subjects factor, heterogeneity text condition: F (1, 52) =0.012, p =.914, partial η2 =.000, control condition: F(1, 51) =2.797, p =.101, partial η2 =.052."

q1 · i? · causal · r2

Authors' interpretation in the general discussion of the descriptive and inferential pattern across both studies; empathy was not directly measured as an explanatory mechanism.

"These results indicate that simply reading about heterogeneity is not enough to trigger the process of empathy described, but that the experience of heterogeneity (what it is like) seems to be crucial."
