The study of the implementation of research-based learning model to improve the students’ proving skills in dealing with the resolving efficient dominating set problem

Abstract

Abstract Research-based learning (RBL) is one of a student-centered learning (SCL) method that involves research in the learning process. One of skills that can be developed through RBL model is proving skill. The student’s mathematics proving skill needs to be trained and developed because mathematics is a science that includes definitions and statements that need to be proved. This research was conducted to determine the effect of RBL implementation to improve the student’s proving skill in dealing with resolving efficient dominating set problems. The research was used mixed methods by combining qualitative and quantitative methods. The subjects of the study were divided into two classes, namely 23 students in the control class and 20 students in the experimental class. The homogeneity test of the pretest results for two classes showed p - value of 0.43 09, so that the variants of the classes was homogeneous. The independent t-test on the posttest results of two classes showes p - value of 0.00861 5 (p ≤ 0.05 ). It can be concluded that there is an effect of RBL implementation to improve the students’ proving skills in dealing with resolving efficient dominating set problems.
