The Effectiveness of the Application of Learning Models Creative Problem Solving and Problem Based Instruction: The Impact on Students Mathematics Learning Interest

Abstract

This study aimed to find out the effectiveness of the learning model implementation in the interest in mathematics learning of 5th-grade elementary school students, between the class using CPS (Creative Problem Solving) learning model and the class using PBI (Problem Based Instruction) learning model. The type of this study was quasiexperimental research using post-test only no treatment control design. The population of this study was all 5th-grade elementary school students at the Jenderal Sudirman cluster in South Denpasar in the academic year 2019/2020. The sample was determined using a random sampling technique. The data obtained was the interest in learning mathematics using a questionnaire. The result of this study showed that there was a difference in the interest of students learning between the two classes, seen from the result of the t-test, namely tcount>ttable. The result of the effect size test was 0,74, with moderate criteria. This is in accordance with the theory and previous research that has been carried out which states that interest in learning is one of the intrinsic factors that affect learning outcomes, this interest in learning is strongly influenced by various factors including the application of learning models. According to the results of research conducted, the CPS learning model is more effectively applied than PBI to increase students' interest in learning
