Abstract

 ABSTRAK This study aim to describe the students’ thinking process of 9th grade of Junior High School has a high mathematics capability in solving the mathematics problem based on Polya rule.This study is qualitative descriptive research. The criteria of subject selection included the students’ has a high mathematics capability and communication fluency both spoken and written. The data collection was done using written test and task-based interview techniques. Data analysis done based on written test data and task-based interview techniques data. And then it has been done the method triangulation to get valid subject data. Finally, the result of description thinking process as follows: students with high mathematics capability, in understanding problem using assimilation thinking process, make a plan using assimilation and accommodation thinking process. Assimilation thinking process can be identified when the students can mention the prerequisite material, can directly relate the sides kite (BF = FG) and can directly develop problem solving plan. Meanwhile, accommodation thinking process can be seen when the students drew an auxiliary line from E to the right thereby intersecting with CD line (the intersection was labeled H point), so devided trapezoid AEDG become right triangle EHG and rectangle AEHD. In carrying out a plan and in looking back at the completed solution, the students used assimilation thinking process. Keywords: thinking process, mathematics problem, and problem solving.
