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? At pretest the control group's mean was significantly higher than the experimental group's, but after the CLIL strategy the experimental group improved and became statistically similar to the control group. → Carolina Salamanca & Sara I Montoya 2018

q2 · i? · causal · r1
Quasi-experimental non-equivalent control group study with 33 experimental and 30 control Nursing-program students. Independent t-tests gave pretest sig 0.024 (control mean 48.6 vs 41.48) and posttest sig 0.142 (means 69.07 vs 63.58), so "becoming statistically the same as the mean of the control group".
"the mean of the control group was significantly higher than the mean of the experimental group, and after applying the CLIL strategy, it was observed an improvement of the experimental group, becoming statistically the same as the mean of the control group."
Discussion¶
Related Claims¶
- Item-level gains differed by group: the experimental group improved significantly on items E and F while the control group did not, and vice versa for items A and C — related
- Both experimental and control groups improved significantly from pretest to posttest over the four-month period — related
- Experimental-group students received 610 more minutes of English exposure than control-group students through the CLIL applications — related
- Before implementation, treatment students performed significantly below control students on the standardized reading test — a narrower finding that bears on this claim
