Problem-based learning and ethnomathematics on mathematical understanding

Abstract Mathematical understanding is very important aspect for students in elementary school. However, the mathematical understanding is still low. Innovative learning mathematics is chosen as a solution to improve mathematical understanding by using problem-based learning and ethnomathematics. The purpose of this research is to know how the effect of problem-based learning approach with ethnomathematics on mathematical understanding. The method used in this research was Four-D models which consists of: Defining, Designing, Developing, and Disseminating. The subjects of this research consisted of 83 students from fourth grade elementary school. The selected samples of research will be divided into experimental class and control class. The instruments used were the mathematical understanding test, and student response questionnaire. The result of the research showed problem-based learning and ethnomathematics have a positive effect on mathematical understanding. Problem-based learning and ethnomathematics is better than conventional learning to improve mathematical understanding. The new finding in this research from the questionnaire result was students prefer modern culture rather than local culture.
