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 year-long 1993–94 quasi-experiment, students in experimental Algebra Cognitive Tutor classes outperformed comparison classes by 15% on standardized tests and 100% on tests targeting the course objectives. → Kenneth R. Koedinger & Vincent Aleven 2016

The interview restates the headline result of the 1997 year-long quasi-experiment in three Pittsburgh city schools: “the 470 students in experimental classes outperformed students in comparison classes” by 15% on standardized tests and 100% on course-objective tests. No effect size is printed, so impact is null.
"On average the 470 students in experimental classes outperformed students in comparison classes by 15 % on standardized tests and 100 % on tests targeting the [course] objectives."
