q3 i2 The four knowledge items correlated significantly with self-assessed knowledge at pretest (r = 0.238) and posttest (r = 0.343). → Mulders 2025

Evidence¶

Mulders 2025¶

Mulders, M., Träg, K. H., & Kirner, L. (2025). Go green: evaluating an XR application on biodiversity in German secondary school classrooms. Instructional Science. https://doi.org/10.1007/s11251-024-09697-1

q3 · i2 · associational · r1

Correlational analysis in the experimental condition linking the four-item knowledge test to the single self-appraisal item, with printed correlations "r = 0.238" (pretest) and "r = 0.343" (posttest); the article uses this to argue self-assessments were "at least somewhat accurate".

"For the total sample, scores on the knowledge test correlated significantly with the self-assessed knowledge item in both the pretest (t(106) = 2.52; p = 0.013; r = 0.238) and the posttest (t(104) = 3.72; p < 0.001; r = 0.343)."
