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? The 2008 cohort (n = 10) evidenced a statistically significant improvement in literacy knowledge from pretest to posttest. → Pufpaff 2010

q2 · i? · causal · r1

Pretest-posttest study of the 2008 cohort (n = 10) in the co-taught literacy unit. The mean pretest was 12.70 (SD = 3.16) and the mean posttest was 18.10 (SD = 3.11) of a maximum possible score of 26, with "positive gain scores ranged from 1 to 11 with a mean of 5.4 points."

"In 2008 ( n= 10), the mean score for the pretest was 12.70 (standard deviation [SD] = 3.16; range = 9 - 17) whereas the mean score for the posttest was 18.10 ( SD = 3.11; range = 15 - 23) of a maximum possible score of 26."

q2 · i? · causal · r1

Paired samples t test on the 2008 cohort's pretest-posttest scores showed "a signi Þcant improvement (t(9) = 4.32, p = .002)". No effect size is printed, so no magnitude is reported.

"A paired samples t test was computed comparing the pretest scores to the posttest scores. Participants evidenced a signi Þcant improvement (t(9) = 4.32, p = .002)."
