Using Open-ended Problem-solving Tests to Identify Students’ Mathematical Creative Thinking Ability

This study aimed to examine an open-ended problem-solving assessment tool that can be used measure the profile of students’ mathematical creativity based on type creativity. The consists sheets and interview guidelines students' One hundred five students were asked solve problems. From each group, one student was selected interviewed with aim obtaining a more detailed explanation these types. two types explained as follows. “very creative” those who could perform cognitive flexibility fluency in solving other creative able think flexibly (cognitive flexibility) when Cognitive includes ability describe various solutions provide than answer problem. interpret smoothly accurately without any constraints. It may also refer correct wrong even though there mistake during operating process. analysis results showed effective terms (products) processes. In (products), it determine ability, namely very creative, while processes, differences
