Subclaims¶

q3 i0 For noncognitive effects of multigrade classes, the weighted average d-index was near zero once outliers were excluded, with the confidence interval including zero. → Simon Veenman 1996

Meta-analysis of noncognitive effects of multigrade classes (Table 2): with outliers excluded and zeros included, d = -.003 (k = 13, N = 14,556, CI -.04 to .03, Q = 17.25, homogeneous). The overall all-studies estimate was d = +.07 with CI including zero.

Discussion¶

Related Claims¶

• Multi-age classes show no significant cognitive or noncognitive differences from single-age classes — possibly the same claim (merge candidate)
• Meta-analysis shows no significant difference in cognitive outcomes between multigrade and single-grade classes — related
• Country of publication moderates multigrade cognitive effects, with a small negative effect only for European studies — related
• Multigrade classes show negative weighted effects for science and social studies but not English as a foreign language — related
• Grade level moderates multigrade cognitive effects, with a diminishing positive effect from lower to higher grades — related
• Staff development for multigrade teachers improved time-on-task and teaching skills but did not raise achievement relative to untrained single-grade classes — related
• Evidence for a selection bias favoring multigrade classes is limited, found explicitly in only 4 of 51 studies — related
