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.
q4 i2 In Wills et al. (2018), the percentage of time on-task was 80.00 in CW-FIT classes versus 58.80 in comparison classes (effect size 1.38, improvement index +42, p<0.01). → wills-2018-ontask

Multisite randomized replication trial rated Meets WWC Group Design Standards Without Reservations, with 324 students in K to 6 across 21 schools in Missouri, Tennessee, and Utah, measured at multiple time points in late fall to early spring. On-task percentage averaged 80.00 (17.50) versus 58.80 (15.61), effect size 1.38, improvement index +42, statistically significant (p<0.01).

Related Claims¶
- In a cluster randomized trial, CW-FIT classes showed a lower percentage of time displaying disruptive behaviors than comparison classes over six months — related
- CW-FIT has positive effects on student behavior, with strong WWC evidence across six studies in kindergarten through grade 10 — a broader claim this one bears on
- CW-FIT has positive effects on teacher practice, with promising WWC evidence across five studies in prekindergarten through grade 7 — related
- CW-FIT substantially increases teacher praise statements but shows no statistically significant effect on some reprimand measures — related
