Improving Student’s Mathematical Problem-Solving Skills Through Relating-Experiencing-Applying-Cooperating-Transferring Learning Strategy and Graphic Organizer

This study aimed to (1) improve student's mathematical problem-solving skills and (2) know student's responses of the implementation of Relating-Experiencing-Applying-Cooperating-Transferring (REACT) learning strategy with graphic organizer. This type of research is a classroom action research (CAR) which conducted in three cycles. The subjects of this study were 38 students of VIII-14 class SMP Negeri 2 Singaraja. Student's problem-solving skills data were collected by using problem-solving tests and student’s responses were collected by using questionnaires. The data that have been collected was analysed descriptively. The results showed that the stages of REACT learning strategy and a graphic organizer that used during the learning process can improve student's mathematical problem-solving skills. The improvement can be seen from the increased average score of student's mathematical problem-solving skills from 29.1 in the initial reflection and continued to increase to 69.5 in the last cycle, learning completeness also increased from 5.26% on initial reflection and increased to 81.58% in the last cycle as well as average score of student’s responses that were collected through questionnaires was in positive category.
