Subclaims¶
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 i? Post-policy below-norm students reported much more frequent interactive pedagogy than pre-policy below-norm students, a .55 SD difference versus above-norm students' change (P<.001). → Takako Nomi 2010

q3 · i? · causal · r2
Survey-based Rasch measures of interactive pedagogy in the cross-cohort discontinuity analysis. The article attributes this to professional development, curricular resources, and added instructional time; compositional controls did not change the coefficients.
"Post-policy, below-norm students reported much more frequent use of interactive pedagogy than below-norm students pre-policy, the difference in the post-policy changes between below- and above-norm students was .55 SD (P<.001)."
Discussion¶
Learner Variables¶
- Algebraic Thinking — moderator: an instructional effect differs with it
Related Claims¶
- Double-dose algebra policy increased academic demand for both high- and low-skill students, with below-norm students' gains not attributable to peer ability changes — related
- Interactive pedagogy increased nearly half a standard deviation for below-norm students in homogeneous double-dose algebra classes — possibly the same claim (merge candidate)
- Below-norm students' algebra test scores improved despite having lower-skill peers post-policy, consistent with additional supports offsetting compositional decline — related
- Interactive instruction is more common in classrooms with higher prior achievement; didactic and review are more common in lower-achieving classrooms — related
- Teachers with more professional preparation use interactive instruction more often — related
- Algebra failure rates rose post-policy for above-norm students (~3 percentage points) but fell for below-norm students (~4 points); classroom environment and peer ability explained most of the above-norm rise but not the below-norm fall — related
- Chicago's double-dose algebra policy raised algebra test scores for both low-skill and high-skill students — related
