PENGGUNAAN ALAT PERAGA KARTU POSITIF DAN NEGATIF UNTUK MENINGKATKAN HASIL BELAJAR PENJUMLAHAN DAN PENGURANGAN BILANGAN BULAT DI SEKOLAH DASAR
The purpose of this study was to determine the improvement of the process and learning outcomes of addition and subtraction of integers using positive and negative card props for elementary school students. The type of research used is Classroom Action Research (PTK). The subjects in this study were students of grade IV Elementary School, totaling 21 student. The data collection techniques used were tests and direct observation. The mastery criterion used in this study is that if students' completeness classically reaches 80% with an average value ≥ 65, then the research cycle can be stopped and considered successful. The results of the research in the first cycle showed an increase in the percentage of 76.19% with an average value of 68.65. In the second cycle it increased to 90.48% with an average value of 80.55. This means that the completeness of learning in the class has reached the target set. Thus, it can be concluded that the use of positive and negative cards can improve learning outcomes for addition and subtraction of integers.
