ABSTRACT

This purpose of this research is to describe students’ algebraic thinking processed in mathematic problem solving based on mathematic ability with cluster studied. This research was conducted by using quantitative approach with descriptive method. Elements of algebraic  thinking used Kieran (2013:) like as problem solving ability, representation ability, and quantitative reasoning ability which had modified by importan researched. Tis research used algebraic thinking test paper and transcript of interview to support the result. The results showed that algebraic thinking proocessed by advance mathematic ability get GOOD performance, algebraic thinking processed by intermediate mathematic ability get GOOD performance, and algebraic thinking processed by low mathematic ability get LESS performance
