ANALISIS KEMAMPUAN KOMUNIKASI MATEMATIS BERDASARKAN GAYA BELAJAR VISUAL

Abstract

This study aims to investigate the effect of the problem-based learning model and students' worksheets on the ability to understand mathematical concepts of learners. This is a quantitative study using a quasi-experimental with the nonequivalent type posttest only control group design. The population are all students of class VII SMP 174 Jakarta in the 2018/2019 school year. The samples are 71 students from classes VII-D and VII-G. The sampling technique is a cluster random sampling. Data collected using instruments of understanding mathematical concepts. The distribution of experimental and the control class are normal. Hypothesis testing produces a t-test of 1.9521, which is rejected H0 at a significance level of 5% with an effect size of 0.5343 which is classified as moderate. The results of this study indicate that there is an effect of the problem-based learning model based on student worksheets on the ability to understand mathematical concepts with moderate criteria.
