Increasing Interest and Learning Outcomes in Mathematics using PBL with Cards in Grade 3 Elementary School

Abstract

 One of the subjects in education is mathematics. Mathematics is the science of reasoning that underlies almost all aspects of human life and the universe. In studying mathematics, one of the things that cannot be missed is interest in learning. Interest in learning will affect math learning outcomes. In addition to interest, methods and models also affect the success of learning. This study aims to determine the increase in interest and learning outcomes in mathematics by applying the problem-based learning model assisted by card media. The subjects of this study were third grade students with a total of 22 students. This research is classified as collaborative classroom action research with the design of the Kemmis and Mc. Tagart model. The research stages consist of four stages, namely planning, action, observation, and reflection. Data collection techniques using questionnaires, learning outcomes, and documentation. The results showed an increase in student interest and learning outcomes. In the pre-action learning interest category very high 2, high 5, medium 10, low 5. Learning outcomes show there are still 64% of students who need to learn, only 36% have passed the minimum completeness criteria. In cycle I, learning interest was very high 4, high 9, medium 9. Learning outcomes in cycle I showed that 73% had passed and 27% still needed to study again. At the second cycle stage, the learning interest showed very high 8, high 9, and medium 5. The learning outcomes in cycle II showed 14% needed to study again and 86% had passed. From the above research, it is concluded that students' interest and learning outcomes have increased from pre-action to cycle I and increased again in cycle II. This research is expected to add scientific insight for teachers, schools, and other researchers in implementing the PBL model assisted by cards to increase student interest and learning outcomes.
