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 experimental group's pre-to-post gains had effect sizes rNOSS = .83 and rSKS = .61. → Mustafa Metin 2022
q2 i? The control group's pre-to-post gains had effect sizes rNOSS = .41 and rSKS = .24. → Mustafa Metin 2022 (2)
Evidence¶
Mustafa Metin 2022¶
Mustafa Metin. (2022). Comparing Effects of Two Different Explicit–Reflective Instructions on Pre-School Prospective Teachers' View about Nature of Science and Scientific Knowledge. Journal of Science Learning, 5(1), 165-175. https://doi.org/10.17509/jsl.v5i1.33190
q2 · i? · within-group pre-post r only, no between-condition effect size · causal · r2
Paired samples t-tests within the experimental group (n = 33) comparing pre-test and post-test means on NOSS and SKS; the article reports "the effect sizes (r NOSS = .83; r SKS = .61) of this increase are in high level."
"It has been found that experimental group has a significant increase in post -test results (t NOSS = 12.036; p < 0.05; t SKS = 6.396; p < 0.05) and the effect sizes (r NOSS = .83; r SKS = .61) of this increase are in high level."

Mustafa Metin. (2022). Comparing Effects of Two Different Explicit–Reflective Instructions on Pre-School Prospective Teachers' View about Nature of Science and Scientific Knowledge. Journal of Science Learning, 5(1), 165-175. https://doi.org/10.17509/jsl.v5i1.33190
q2 · i? · within-group pre-post r only, no between-condition effect size · causal · r2
Paired samples t-tests within the control group (n = 33) comparing pre-test and post-test means; the article reports "the effect sizes (r NOSS = .41; r SKS = .24)" and labels them high level, though by its own Cohen thresholds r = .24 is small.
"It has been found that control group has a significant increase in post -test results (t NOSS = 4.196; p < 0.05; t SKS = 2.009; p < 0.05) and the effect sizes (r NOSS = .41; r SKS = .24) of this increase are in high level."
Studies bearing on this claim¶
Can instruction shift learners' views of how scientific knowledge is made and judged, and do the shifts last? This table gathers the studies behind this claim and the 7 narrower claims that bear on it: 5 distinct studies (3 design, 1 causal, 1 qualitative), q1–q3, 0 of 5 with an effect size coded. One row per study, codes as each entry records them; no effect is averaged and no verdict is drawn. Built by scripts/synthesize_claim.py from eval/synthesis/; a row that looks wrong is fixed on the claim it comes from.
