Conceptual understanding and mathematical disposition of college student through Concrete-Representational-Abstract approach (CRA)

Abstract

The purpose of this study is to examine whether the improvement of mathematical conceptual understanding of students whose learning using Concrete-Representational-Abstract (CRA) approach is better than direct learning, and to know the relationship of mathematical conceptual understanding with mathematical disposition of students. The method used in this research is quantitative. The population in this study is the students of the Department of Mathematics at the second level in Cimahi, the sample is two classes of students who contract Mathematics Statistics courses. The instrument used in this research is a mathematical conceptual understanding test, as well as a questionnaire of mathematical disposition. Data analysis using Mann-Whitney and correlation with the help of SPSS software. The conclusion gained is the improvement of conceptual understanding ability of students who learn to use CRA approach better than students with direct learning, and also there is relationship between conceptual understanding with mathematical disposition of student.
