Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i3 The no support and global support conditions produced significantly more accurate drawings than the local support condition (partial η2 = 0.35), and no support and global support did not differ. → Steffen P. Schmidgall 2020

q3 · i3 · causal · r3
ANOVA on drawing quality across the three drawing conditions, F(2,114) = 31.26, partial η2 = 0.35. The global support condition (M = 33.05%, SD = 13.83) also significantly outperformed local support; no support and global support did not differ (p = 0.77).
"It revealed that drawing quality differed significantly between conditions, F(2,114) = 31.26, MSE = 131.49, p < 0.001, partial η2 = 0.35. Bonferroni adjusted multiple comparisons revealed that the no support condition (M = 36.00%, SD = 11.80) constructed statistically significantly more accurate drawings than the local support condition (M = 16.93%, SD = 8.00, SE = 2.60 p < 0.001)."
Discussion¶
Related Claims¶
- All three drawing conditions scored better than the control condition on the drawing test and performed equally well — reports the opposite
- Drawing support increased rather than decreased perceived difficulty, indicating cognitive overload — related
- Drawing conditions that were compared to control outperformed the read-only control condition on transfer performance — related
- Drawing provided no benefit for lower-order recognition knowledge, and the local support condition scored significantly lower than control — related
- Instructional drawing support does not significantly improve students' comprehension or transfer compared with unsupported drawing overall — related
