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 i2 Students who participated in Cignition virtual group tutoring scored 9 percentage points higher on the Cignition fractions assessment than control group students, an effect size of 0.44 standard deviations. → Catherine Pratt 2023

q3 · i2 · causal · r?
A randomized controlled trial of Cignition group tutoring (groups of up to four students) with 157 5th-grade students with complete math achievement data. Tutored students "scored 9 percentage points higher on the Cignition fractions assessment than control group students," an effect size of 0.44 standard deviations.
"Students who participated in Cignition virtual group tutoring scored 9 percentage points higher on the Cignition fractions assessment than control group students, after accounting for baseline differences, which translates to an effect size of 0.44 standard deviations."
Discussion¶
Related Claims¶
- Cignition group tutoring produced slightly higher math confidence and enjoyment than control in an RCT — related
- Tutored students reported positive relationships with Cignition tutors, with little variation in relationship quality across tutors — related
- High-quality tutoring produces large learning gains cost-effectively, in person and virtually — a broader claim this one bears on
- 4th and 5th grade students learning fractions with an ITS show significant learning gains in individual, collaborative, and combined conditions
