Contributions of Self-Regulated Learning, Disposition Mathematically and Habits of Mind Against Mathematical Problem Solving Ability Students

Abstract

This research aims to 1) analyze the effect of self-regulated learning (KB), mathematical disposition (DP) and habit of mind (HoM) on mathematical problem-solving ability (KMP); 2) Contribution value has given by KB, DP, HoM on KMP; and 3) identify the dominant factors to affect KMP. This research was conducted of grade 8 in one of the private junior high schools in North Sumatera, the academic year of 2018/2019 with 32 participating students which were taken with cluster random sampling technique. The research instruments used in this included mathematical problem-solving ability tests and questionnaires. Data were analyzed by Multiple Linear Regression Analysis. The result of this research is 1) KB, DP, and HoM give a positive and significant effect on KMP; 2) Contribution value has given by KB, DP, HoM respectively are 24.26%, 5.8% and 13.32%; and 3) Factor which dominant to affect the mathematical problem-solving ability is self-regulated Learning.
