Mathematical critical thinking skills profile of high school students in solving linear program word problems

Abstract

Critical thinking is one of the most important skills of the 21st century. Students' mathematical critical thinking can develop their concept and knowledge to solve a problem. This research aims to determine the profile and provide information about students' mathematical critical thinking in solving linear program problems. This study was descriptive-qualitative. The data was collected by a test and followed by an interview. The testwas developed based on mathematical critical thinking's indicators, namely:formulating the problem, analyzing and solving the problem, evaluating, and drawing conclusion.The subjects of this study were thirty two students of senior high school in Jepara.The result shows thatamong 32 students, those who can formulate the problem are 12.70%,analyze and solve the problem are 12.17%, evaluate are 11.91%, and draw conclusion are 10.16%.
