Abstract
One of the evaluation standards given by the National Council of Teachers of Mathematics (NCTM) is mathematical disposition. Disposition refers not simply to attitudes but to a tendency to think and to act in positive ways. Creative thinking disposition is the tendency to thinking and acting creativ e ly in mathematics. The aims of this research is to determine the effect of mathematical habits of mind learning based on problems toward the students’ mathematical creative thinking disposition . This research was conducted at one of SMPN (Junior High School) Padang Ratu, Indonesia. The method used in this research is quasi experiment with posttest only control group research design. The population of this research is 2 14 students . The sample of this study is 70 students at grade VII which consists of 36 students in experimental group and 34 students in control group. The experimental group was taught by mathematical habists of mind learning strategy based on problem and the control group was taught by conventional learning strategy ( teacher centered ). The sampling technique used is cluster random sampling . The instrument used to collect data in this research is questionaire checklist to determine students’ mathematical creative thinking disposition . Data analysis used in this research is t-test. The results showed that students’ mathematical creative thinking disposition which is taught by mathematical habits of mind learning strategy base d on problem are better than the students which taught by conventional learning strategy . In future research, we recommend to use the mathematical habits of mind learning strategy base d on problem in learning process to increase student’s creative thinking disposition.
