Analisis kemampuan berpikir kritis dan kreatif dalam pemecahan masalah matematika berdasarkan kemampuan matematika siswa

Abstract

The study is descriptive qualitative, which aimed at describing critical thinking ability and creative thinking in solving problems based on Mathematics ability of students. The research subjects were the entire students of grade XII at SMAN 10 Bone of the first semester academic year 2019/2020 which consisted of 2 students who have high Mathematics ability and 2 students who have low Mathematics ability. Data were collected by using test of Mathematics ability, test of critical thinking to measure critical thinking ability, test of creative thinking to measure students' creative thinking and interview. The results of the study reveal that students who have high Mathematics ability can meet four indicators of critical thinking ability in solving problems, namely able to formulate main issues and reveal facts, able to detect bias and determine the concept to solve the questions, able to work on the questions based on the plan, able to recheck the answers, able to utilize other methods, and draw conclusion. Students who have low Mathematics ability can meet three indicators of critical thinking ability in solving problems, namely able to formulate main issues and reveal facts, able to detect bias and determine the concept to solve the questions, and able to work on questions based on the plan. Students who have high Mathematics ability can meet three indicators of creative thinking ability in solving problems, namely fluency, flexibility, and originality. Students who have low Mathematics ability cannot meet flexibility criteria, namely giving more than one answers (various) in counting process and the results are correct; similar to the originality criteria, namely the students' ability to answer the problems using their own mind in a unique way.
