Abstract

The aim of the research is to describe the profile of problem solving ability of secondary student with high mathematical ability in learning based on realistic mathematics supported by ethnomathematics. The study is a descriptive qualitative research. The subject is a 7th grade student in a public secondary school at Semarang regency, Central Java. The data was collected by test and interview. The student’s problem solving ability was analyzed by using Polya Steps. The results showed that the profile of student’s problem solving ability with high mathematical ability was very good. In the beginning, the student started by understanding the problem completely. Then, they was making good planning to solve the problem, applying the correct process, and producing the right answer. In addition, they could look back the process but incomplete yet. This finding, hopefully, helped teachers in choosing the appropriate strategies or instructional approaches in order to improve the students problem solving ability.
