q2 i? Pre-test NOSS (t = .446) and SKS (t = .931) differences between groups were not statistically significant (p > 0.05). → 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? · causal · r2

Independent samples t-test on pre-test scores in the quasi-experimental study (n = 66 total); NOSS showed no significant difference (t = .446; p > 0.05), and the article likewise reports the SKS pre-test difference (t = .931; p > 0.05) as not significant.

"While pre-test mean of experimental group is higher than the control group’s (x̄Experimental = 87.09; x̄Control = 86.53;) in NOSS, there is not statistically a significant difference between pre-test means of experimental and control groups (t = .446; p > 0.05)."

Related Claims¶

• Both instructional conditions produced statistically significant pre-test to post-test gains in NOS and SK views, with larger effect sizes in the experimental group — related
• In one nonequivalent-groups study of pre-school prospective teachers, the group taught with formative assessment embedded in explicit-reflective instruction scored higher on post-test NOS and SK than the group taught with explicit-reflective instruction alone — related
• The formative-assessment-embedded group retained higher NOS and SK scores than the control group on a retention test four weeks after the intervention — related
• Neither group showed a significant decline from post-test to retention test on NOS or SK measures — related
• Baseline pre-assessment scores showed no statistical differences between treatment and control groups in either the matched or baseline sample. — a broader claim this one bears on
• Chatbot and search engine classes showed no significant baseline differences in science learning ability and knowledge before the intervention — related
• Pupils in all three conditions gained significantly from pre-test to post-test and retention test, with no prior-knowledge differences between conditions — related
• No significant interaction between condition and pre-test knowledge on learning outcomes in either topic — related
• No significant pre-test difference existed between the two groups' entry listening knowledge — related
• High and low CT groups showed comparable prior coding knowledge before the AICA intervention — related
• Model-estimated mixture weights show no detectable difference between control and experimental groups in Study 2 — related
