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 i? Experimental students taught with the direct instruction strategy scored significantly higher on the mathematics post-test than control students taught traditionally, after controlling for pre-test scores. → Al-Makahleh 2011

Evidence

Ahmad Abdulhameed Aufan Al-Makahleh. (2011). The Effect of Direct Instruction Strategy on Math Achievement of Primary 4th and 5th Grade Students with Learning Difficulties. International Education Studies, 4(4). https://doi.org/10.5539/ies.v4n4p199

q3 · i? · causal · r2

Randomized experimental study: 60 students with mathematics learning difficulties randomly assigned to experimental (N=30) and control (N=30) groups; ANCOVA on post-test controlling for pre-test found "statistically significant differences (F=120.51, α<0.05)" favoring direct instruction.

"Table 2 indicate statistically significant differences (F=120.51, α<0.05) among achievements of the experimental and control subjects on mathematics post-test. In addition, as shown in the table, experimental subjects scored higher (M=36.33) than the control subjects (M=18.30)."
