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.
q2 i? In the fourth design iteration, CALI showed strong pre-post unit test effects (d = .86) with no significant CXI interactions. → Dombek 2017

q2 · i? · causal · r?
Fourth design iteration (pre-post correlational design, no control group) found "strong pre-post unit test effects (d = .86)" and "no significant CXI interactions" after switching to all small-group instruction with leveled materials.
"In the fourth iteration, a review of the data revealed strong pre-post unit test effects (d = .86) and there were no significant CXI interactions."
Discussion¶
Learner Variables¶
- Academic and Critical Literacy — moderator: an instructional effect differs with it
