Subclaims¶

q2 i? Posttest differences favoring the experimental group reached significance for measuring, inferencing, controlling variables and generalization (each p <.05). → Kang and Noh 2017 q2 i? Observing, classifying and predicting showed no statistically significant group differences at posttest. → Kang and Noh 2017 (2)

Evidence¶

Kang and Noh 2017¶

Houn Tae Kang, Suk Goo Noh. (2017). The Effect on Elementary Science Education Based on Student's Pre-inquiry. Universal Journal of Educational Research 5(9). https://doi.org/10.13189/ujer.2017.050908

q2 · i? · causal · r1

Posttest t-tests on the Test of Science Process Skills subareas in the same two-class quasi-experiment. The measuring subskill favored the experimental group (2.39 vs 2.13, "significant difference (p <.05)"); the article likewise reports significant differences for inferencing, controlling variables and generalization.

"When we look at the difference of scientific process skills by group in the case of the measuring, 2.13 points in the controlled group and 2.39 points in the experimental group showed a significant difference (p <.05)."

Table 3 posttest t-test row for observing: experimental 1.73 (0.876) vs control 1.97 (0.809), t = 1.124, p = 0.066 — no significant difference; classifying and predicting likewise showed non-significant differences (p = 0.502, p = 0.462).

Discussion¶

Learner Variables¶

• Inferencing — outcome: instruction changes it

Related Claims¶

• Science lessons built on students' meaningful pre-inquiries produce higher total science process skills than traditional textbook lessons in 6th-grade classes — a broader claim this one bears on
• Inquiry-based instruction significantly improved pre-service science teachers' scientific process skills from pretest to post-test in a university biology laboratory — a broader claim this one bears on
• Visuospatial inferencing relates to hypothesis validation and experimentation but not to generating conclusions when linguistic abilities are controlled — related
• Within the eco-hunt group, all six science process skill dimensions improved significantly, with classifying improving most (39.3%) and predicting least (9.2%) — related
