Abstract


This study aims to examine the differences in the patterns of Conservational Reasoning (CR) between students who learn with E-MI and those who learn with MI, as well as the effect of E-MI on students' CR abilities in the context of Newton's laws. This research used quasi-experimental method with a Pretest-Posttest Control Group Design across two classes at SMA Negeri 1 Rogojampi. The test instrument used in this study consists of 2 CR pattern items from the development of the Modified Lawson Classroom Test Scientific Reasoning (MLCTSR), in the form of multiple-choice questions with reasoning (α = 0.828). The data analysis technique used analysis of variance (ANOVA) using IBM SPSS Statistics v.26 for Windows and effect size analysis through an effect size calculator. The results indicate that, statistically, the average CR ability scores of the experimental group were higher compared to the control group. The ANOVA results also showed a significant difference between the CR patterns of the experimental and control groups after the intervention. E-MI had a high impact on students' CR abilities, with an effect size of 94%, and the majority of the experimental group students' CR patterns were at the SEF category level for all items. This suggests that E-MI has a positive impact and significantly improves students' CR abilities on the topic of Newton's laws compared to MI.
