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 i3 On the 27 items children originally performed at chance, there was a significant Test × Condition interaction (ηp2=.19) favoring symbols-only training. → Mix 2014

q3 · i3 · causal · r1

Experiment 3 assigned 24 kindergarteners to symbols-only or base-10 blocks training (five lessons over 2 weeks). On difficult numerals items, a Test × Condition interaction, F(1, 22) = 5.03, p = .01, ηp2=.19, favored symbols-only training; "there was a significant increase from pre- to posttest for the symbols-only group."

"there was a significant increase from pre- to posttest for the symbols-only group, t(11) = 4.24, p = .001, but not for those who received training with blocks (Mpretest = .50, SD = .10; Mposttest = .51, SD = .13), t(11) = .32, p = .75"
