Abstract
The study aimed to assess the effectiveness of the Predict-Explain-Enact-Observe–Reflect (PEEOR) instructional strategy on general science students’ conceptual understanding and motivation in the topic of motion and force. The research employed a pre-test post-test quasi-experimental design. The sample consisted of 107 general science summer, year II students from Woldia College of Teacher Education. Data collection involved a conceptual understanding test (comprising 15 questions) and a post-motivation questionnaire. The KR-20 reliability value for the conceptual understanding test was 0.75. The Cronbach Alpha (α) reliability coefficient for the scale was determined to be 0.84. Descriptive statistics and ANCOVA revealed the following: The PEEOR group (adjusted mean = 6.787) significantly outperformed the traditional group (adjusted mean = 5.134). The POE group (adjusted mean = 6.472) did not differ significantly from either PEEOR or the traditional group. Regarding student motivation: There was a statistically significant difference (p < 0.05) in post-test motivational questionnaire (PMQ) scores among the three groups. The F-statistic for this difference was 4.753. The study recommends that college physics teachers adopt the PEEOR instruction strategy. Additionally, the college and department heads of natural science should promote the potential benefits of this novel strategy among science educators.
