Efforts to Improve Student Learning Outcomes By Using Phet Colorado Learning Media in Fractional Material for Class 5a in Min 1 Boalemo

Abstract

This study aims to improve students' learning outcomes in understanding the concept of fractions through the use of PhET Colorado interactive learning media. Mathematics learning, especially in fractional materials, is often a challenge for students because of its abstract nature. Therefore, learning media is needed that can help students understand the concept of fractions more visually and interactively. This study uses the Kemmis & McTaggart model Classroom Action Research (PTK) method which consists of two cycles. Each cycle includes stages of planning, action, observation, and reflection. The subject of this study is a student of class 5A MIN 1 Boalemo. Data was collected through learning outcome tests, observations, and student questionnaires. The results showed that the use of Colorado PhET in fractional learning was able to improve student learning outcomes. This can be seen from the increase in the average score of the learning outcome test from pre-cycle to cycle 2. In addition, students become more active and enthusiastic in learning. Thus, the use of PhET Colorado as an interactive learning medium can be an effective alternative in improving the understanding of the concept of fractions in elementary schools.
