Identification of critical thinking skills in mathematics students of class VIII SMPN 61 West Jakarta

Abstract

Critical thinking skill is one of the highest levels of cognitive abilities. This competence is needed to support students in thinking and resolving problems in daily life. Initial identification requires students' critical thinking ability to be a guide in designing a model or strategy of learning. The purpose of this study is to know and describe students' critical thinking ability to solve mathematical problems in the circular matter, with a qualitative approach. The data-gathering technique uses a critical thinking skill test for as many as three problems with a circle matter. Further interviews are conducted to strengthen students' critical thinking abilities. Research instruments are praised on 34 students living in the viii class 61 Jakarta. The selection of the subject of research is based on the results of researchers' observations on the issues in the field that were discussed with the teacher of the subject. The results of the student's work are studied by pointing to critical thinking ability indicators that researchers have established - interpretation, analysis, evaluation, and inference. Research shows that students' critical mathematical thinking ability is at low criteria, where an interpretation attainment indicator is 38.24%; Analysis of 49.02%; evaluation of 47.3%; And inference at 26.47%.
