Analysis of students' mathematical creative thinking ability in three variable linear equation system materials with posing problems.

This study aims to describe the ability to think creatively mathematically in class XI SMA Negeri 1 Singosari in the Three Variable Linear Equation System (SPLTV) material with the Problem Posing model. This research uses a descriptive qualitative approach. The research subjects were six students of class XI SMA Negeri 1 Singosari. Subject selection is carried out by selecting candidate subjects who most meet the indicators of creative thinking. The instruments used were in the form of essay test questions, as many as two items about the Three-Variable Linear Equation System with the Problem Posing model, and interview guide instruments used to confirm the results of student answers on the description questions that had been worked on and to find out more about how students' ideas can arise when working on essay questions which are given. Validators from the Department of Mathematics lecturers validated the instruments used during the research. The results of the job description question and the results of the interviews were identified and then described in the form of a description. This research describes the achievement of students' mathematical creative thinking indicators. Based on the study's results, students can think creatively on fluency indicators seen from students not experiencing difficulties when developing problems and being able to convey the information in the questions smoothly during the interview session. The flexibility indicator is owned by students seen from students being able to develop various problems and solve problems using more than one solution method. Originality indicators can be seen in the work of students who use their language when developing problems. Furthermore, elaboration seen from the students can describe or describe the information provided into a problem and detail every solution. Based on the results obtained, it can be said that students have fulfilled all the indicators of mathematical creative thinking. [ABSTRACT FROM AUTHOR]
