Subclaims¶

q3 i2 Math self-concept change scores correlated positively with temporal comparison-related belief change scores directly after the intervention in both groups (r = .30 and r = .28). → Hörsch 2026

Long-Term Effects of an Intervention Targeting Dimensional and Temporal Comparisons on Students' Math and English Academic Self-Concepts: A Waiting-List Replication and Extension Study.

q3 · i2 · causal · r2

Within the same models, "the math self-concept change scores correlated positively with the change scores of the temporal comparison-related belief directly" after the intervention in both groups, with printed correlations r = .30 (Group A) and r = .28 (Group B), supporting Hypothesis 5; correlations at follow-ups were also positive.

"the math self-concept change scores correlated positively with the change scores of the temporal comparison-related belief directly (Group A: rDiff2_1 = .30, p <.001; Group B: rDiff3_2 = .28, p <.001)"

Discussion¶

Learner Variables¶

• Academic Self-Concept — outcome: instruction changes it

Related Claims¶

• The COMPASS intervention significantly increases students' belief in the positive interdependence of mathematical and verbal abilities immediately and at follow-ups in both groups — related
• The COMPASS intervention significantly increases students' math self-concept immediately after participation in both an intervention group and a waiting-list control group — related
• The COMPASS intervention significantly increases students' belief in the changeability of abilities immediately and at follow-ups in both groups — related
• Math self-concept gains from the COMPASS intervention are sustained at three- and six-month follow-ups in Group A, but the three-month gain in waiting-list Group B was not statistically significant — related
