UPAYA MENINGKATKAN PRESTASI BELAJAR HITUNG PECAHAN DENGAN PENDEKATAN MODEL PEMBELAJARAN JIGSAW

The problems of the research are: (1) How is the effect of Jigsaw model in mathematic learning of fraction material? (2) Can the implementation of Jigsaw model in learning mathematics of fraction material improve the students‟ achievement? The objectives of the research are: (1) to know the effect of Jigsaw model in learning to mathemathics achievement of fraction material, (2) to know that the implementation of Jigsaw model can improve the students‟ achievement in fraction material.The research uses action research in two cycles. Each cycle consists of four stages. They are planning, implementing and observing, reflecting and revising. The subjects of the study are sixth grade students of SDN 1 Bogoran, Kampak, Trenggalek. It consists of 25 students. The data is obtained from the result of formatif test and observation sheet during the teaching and learning activity. The result of analysis shows that the students‟ achievement improves from cycle 1 to cycle 2. On cycle 1, the mean score was 6.4, and on cycle 2 was 7.0. So it can be concluded that Jigsaw model as one of Contextual Teaching and Learning component is good to be used in learning process and can be applied for all subjects, not only for mathematics.
