【 摘 要 】

This research is experimental quantitative about quasi experiment that emphasize on improve mathematical understanding and problem solving for Junior High School students by inductive-deductive implementation. The population of this research are all of students at IX degree students in Subang 2012/2013. Two of nine classes were chosen as sample for this research. The topic which used is probability including random occurrence, basics of chance, relative frequency, calculation of probability, determining the value of probability, the expected frequency and the combined odds of two events. The instrument that was used are test and non-test. Mathematical understanding and problem solving were used as a test methods. Meanwhile questionnaire, and observation sheet were used as non-test methods. The data was analyzed by Mann-Whitney and t-test. According to whole analyze in this research, can be concluded: 1) the student improvement of mathematical understanding by using inductive-deductive approach is in middle quality, 2) there is no significant difference at improvement mathematical understanding between experimental class and control class, 3) the improvement of student's ability in mathematical problem solving that use inductive-deductive approach has a low quality, 4) there is no significant difference at mathematical problem solving between experimental class and control class, 5) most of students has positive responses to mathematic learning by inductive-deductive approach, although the students have many problems when learning takes place.
