Note: Within-group d for skills used raw data with paired correlations; for knowledge and confidence, approximate d values used pooled SDs due to unavailable raw data correlations. Between-group d used post-test scores. Effect sizes are interpreted as small (d = .20), medium (d = .50), or large (d = .80), per Cohen (1988). *p < .05, **p < .01.
