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? Experiment group expressive language posttest standard scores were significantly higher than the control group's (z=-2.016, p=0.044). → Okyay 2017 q3 i? Experiment and control groups did not differ significantly on receptive language posttest scores (z=-1.589, p=0.112). → Okyay 2017 (2)

Evidence¶

Okyay 2017¶

Okyay, O. & Kandir, A. (2017). Impact of the Interactive Story Reading Method on Receptive and Expressive Language Vocabulary of Children. European Journal of Educational Research, 6(3), 395-406. https://eric.ed.gov/?id=EJ1149725

q3 · i? · causal · r1

Mann-Whitney U comparison of TIFALDI posttest scores for 26 experiment versus 26 control children; expressive means 130.1 versus 124.5, with the experiment group significantly higher (z= -2.016, p= 0.044). No effect size is printed.

"In the case of the standard scores the experiment and control groups achieved in the expressive language post -test, however (z= -2.016, p= 0.044) there is a statistically significant difference (p<0.05)"

Okyay 2017 (2)¶

q3 · i? · causal · r1

Mann-Whitney U comparison of receptive posttest scores: experiment mean 133.8 versus control mean 130.1, not statistically significant (z=-1.589, p=0.112). The article notes the experiment mean was still higher; equivalence was not tested.

"the standard scores the experiment and control groups achieved in Turkish Expressive and Receptive Language Test (T IFALDI), Receptive Language Sub -Test does not exhibit a statistically significant difference (z=-1.589, p=0.112)"
