Analyzing theeffect of students' habits of mind to mathematical critical thinking skill

Abstract

Critical thinking is an essential skill to enhance students' capability in Mathematics. One of factor that can affect this skill is Habits of Mind, because the implementation the Habits of Mind in mathematics learning can help the ability to think logically, systematically, accurately, and even critically. This research aims to analyze the effect of students' Habits of Mind to mathematical critical thinking skill. The sampel of this study were 30 students of senior high school from 11th grade (aged 15 - 16 years) in one of the public schools in Medan, North Sumatra, Indonesia selected by using purposive sampling technique. As a quantitative research, this research uses a linear regression statistic. The data is collected through a series of test, observation and interview. The results show that the students' Habits of Mind affect the students' mathematical critical thinking skill significantly, in which Habits of Mind has the effect of contribution as much 51.4% to mathematical critical thinking skill. It describes that Habits of Mind give a positive effect to the mathematical critical thinking skill. It is obtaided by applying the regression linear test toward the students' score in mathematical critical thinking skill and Habits of Mind.
