Subclaims¶

q3 i2 On distal whole-number computation measures, the treatment group significantly outperformed the comparison group on TEMI-O Mathematics Computation (p = .001; g* = .44); the SAT-10 Mathematics Procedures difference (p = .05; g* = .23) was not statistically significant after Benjamini-Hochberg adjustment. → Bryant 2011

q3 · i2 · causal · r2

ANCOVA of distal outcome measures in the same randomized design (139 treatment, 65 comparison). The article reports TEMI-O Computation as significant with printed effect size g* = .44, and SAT-10 Mathematics Procedures as p = .05 with g* = .23 but not significant after Type I error adjustment.

"there were statistically significant differences on TEMI-O Computation {p = .001; g* = .44) and on SAT-10 Mathematics Procedures {p = .05; g* = .23), though this latter difference was not statistically significant after Benjamini-Hochberg adjustment"

Discussion¶

Related Claims¶

• The intervention produced no significant group differences on distal problem-solving measures, as the authors predicted because problem solving was not directly taught — related
• First-graders with mathematics difficulties receiving the Tier 2 early numeracy intervention outperformed comparison students on the aligned TEMI-PM Total Score progress-monitoring measure (g* = .50) — related
• The intervention produced significant effects on the Addition/Subtraction Combinations, Place Value, and Number Sequences subtests but not on Magnitude Comparisons — related
