Analysis of Students Critical Thinking Skills in Terms of Self-Efficacy in Realistic Mathematics Education Assisted Learning Android-Based Media

Learning is conducted using the Realistic Mathematics Education model supported by Android-based media, which can assist students in enhancing critical thinking skills. The objective of this study was to evaluate students' critical thinking abilities concerning self-efficacy within Realistic Mathematics Education learning, aided by Android-based media. This research employed a mixed method design with a sequential explanatory model that integrates both quantitative and qualitative research. The subjects in this study consisted of grade VI students from elementary schools in the Halmahera cluster. The selection of research subjects was performed through purposive sampling, specifically grade VI SDN 3 Kamolan as the experimental group and grade VI SDN 1 Kamolan as the control class. Data collection methods included tests for critical thinking skills, self-efficacy questionnaires, interviews, observations, and documentation. From the experimental class, six students were selected two from the high self-efficacy category, two from the medium category, and two from the low category for qualitative analysis using the interview method. The findings revealed that learning through the Realistic Mathematics Education model, supported by Android-based media, is effective, indicating that quantitatively, RME learning with Android-based media is of high quality. More than 75% of students achieved proficiency in critical thinking abilities, the average critical thinking skills of students met the actual KKM, the average critical thinking skills in the experimental class surpassed that of the control class, the proportion of students’ critical thinking skills in the experimental class was greater than that in the control class, there was an improvement in students’ critical thinking abilities following RME learning with Android-based media, and there was an influence of self-efficacy on students’ critical thinking skills within RME learning backed by Android-based media. Students demonstrating high self-efficacy possess critical thinking skills across all indicators, students with moderate self-efficacy do not fully exhibit critical thinking skills across all indicators, while students with low self-efficacy nearly fail to meet all indicators.
