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? Students in single-discipline courses scored typically three or four points higher on average on fall math, reading, and science assessments. → Naomi Duran and Susan Kowalski 2026

Descriptive comparison of fall 2023 RIT scores by course type, shown in Figure 4. The article reports "students in single-discipline courses scored typically three or four points higher on average on all subjects," equivalent to about a full year of growth in reading and science.
"students in single-discipline courses scored typically three or four points higher on average on all subjects. Three or four points is equivalent to approximately a full year of growth in reading and science, and half a year’s growth in mathematics."
