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? The VCR tutor, a complete ITS for programming video cassette recorders, was demonstrated to provide learners with statistically significant performance gains. → Gord McCalla · Julita Vassileva 2021

The introduction reports, describing Mark and Greer's VCR tutor project, statistically significant performance gains in using the VCR, which the editors call "a rare result for ITSs in those days". No effect size is printed.
"This tutor was also highly effective, and was demonstrated to provide its learners with statistically significant performance gains in using the VCR, a rare result for ITSs in those days."
Discussion¶
Related Claims¶
- ITSs as core or supplementary components of instruction show positive learning gains in individual studies, including ALEKS, Writing Pal, and eDia platform deployments — a broader claim this one bears on
- Ma et al. (2014) meta-analysis: step-based ITSs outperformed no tutoring and large-group teacher-led instruction, but showed no differences against small-group or one-to-one human tutoring — a broader claim this one bears on
- Most ITS-versus-teacher studies in K-12 report a positive effect of ITSs on student performance, with medium-to-large effect sizes — a broader claim this one bears on
- Effects of ITSs are mitigated when compared to non-intelligent tutoring systems: three of four comparisons found no significant difference in learning gains — related
