Problem based MHM-Strategy to enhance junior high school students mathematical creative problem solving ability and mathematical disposition

Abstract

This article presents the results of research on the development of mathematics learning with problem based Mathematical Habits of Mind (MHM) strategy to enhance mathematical creative problem solving (MCPS) ability and mathematical disposition. Quasi experimental research with posttest control group design involved 146 eighth grade students from two State Junior High Schools in Subang regency, each consisting of two classes. The instruments used were tests MCPS ability and mathematical disposition. Research data of students pretest, posttes, and normalized gain scores for MCPS ability were analyzed using two-way ANOVA and Mann Whitney. Based on data analysis results, it is found that there is a significant difference in the enhancement of students MCPS ability and mathematical disposition of students between the experimental and control groups at the high and medium school levels. On the other hand, there is a difference in mathematical disposition in terms of school level. Meanwhile, there is an interaction effect between problem-based MHM strategies and school-levels on the student’s mathematical disposition. Conclusion, that the enhancement of MCPS ability of students who were taught with problem-based MHM strategy is significantly greater compared conventional learning in terms of school level.
