The aim of this research is to  describe the profile of junior high school student high order thinking in resolving mathematics problem based on reflective cognitive style and impulsive.  The research steps started by choosing class which is done deliberately, continued by giving MFFT cognitive style in order to choose research subject. The chosen research subjects two junior high school student at grade eighth with impulsive and reflective cognitive style. Both of the subjects fulfill the criteria which is having the equal mathematic capability and same gender also the capability to communicate well. The chosen students as research subjects were given problem resolving test in order to know the high order thinking profile. Then the interview done toward the research subjects. Meanwhile the validity data checking was done using time triangulation. In conducting this study, two eighth-grade students from Junior High School were involved. Thus, the students’ activities during the research process were recorder so that they can be analyzed. The retrospective analysis of the research process showed that a student who have reflective and impulsive cognitive style have different high order thinking in mathematics problem solving
