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? Across 17 single-case design experiments in the writing achievement domain, 15 (88%) documented a positive effect and 0 documented a negative effect, yielding a WWC rating of potentially positive effects. → Self-Regulated Strategy Development: WWC Intervention Report 2017

q2 · i? · review · r3

The WWC's systematic review of single-case design studies of SRSD for students with specific learning disabilities. Ten studies met pilot single-case design standards with reservations, nine of which have findings in the writing achievement domain; the review's visual analysis found "15 experiments (88%) documented a positive effect, and 0 experiments documented a negative effect." No effect size is printed.

"Across the 17 single-case design experiments for the writing achievement domain, 15 experiments (88%) documented a positive effect, and 0 experiments documented a negative effect."

Discussion¶

Learner Variables¶

Learning Disabilities and Developmental Differences — moderator: an instructional effect differs with it

Outcomes of students with disabilities improve when they receive specially designed instruction responsive to assessment data — the general claim this finding bears on, with the studies behind it
Self-regulated learning improves achievement — the general claim this finding bears on, with the studies behind it
No SRSD study met WWC group design standards; 10 of 14 eligible single-case design studies met pilot standards with reservations — related
Single-case design evidence for SRSD on math achievement does not reach the WWC threshold for inclusion in effectiveness ratings — related
