THE ABILITY OF MATHEMATICAL REPRESENTATION AND STUDENT RESPONSE THROUGH PROBLEM-BASED LEARNING MODEL BASED ON MATHMAGIC IN ALGEBRA MATERIAL IN GRADE VII OF JUNIOR HIGH SCHOOL

Abstract

The purpose of this research is to demonstrate the mathematical representation abilities between students who participate in learning using a mathmagic-based problem-based learning model and the mathematical representation abilities of students who use the conventional lecture method. The research subjects involved 36 students from SMP Negeri 4 Sungai Raya, consisting of class VII B as the control class and class VII F as the experimental class. The research method used is quantitative, with instruments in the form of short answer questions packaged in a math magic format. The data was analyzed using normality tests, homogeneity tests, and hypothesis testing through independent sample t-Test and Pearson Product Moment correlation tests. The results of the study indicate that the problem-based learning model based on mathmagic is more effective in enhancing mathematical representation skills compared to the conventional lecture method, with a significance value of 0.035 indicating a difference in average ability between the two classes. In addition, the results of the Pearson correlation test showed an r value of 0.228, indicating a positive relationship between students' mathematical representation skills and their responses, where students with higher representation skills tend to provide positive responses.
