Abstract

The mathematical communication skills of students in elementary schools are still deficient. This happens because students' mathematical communication skills are not developed in elementary schools. In this study, the problem-based learning model (PBL) is applied with the help of interactive worksheets. The PBL model improves students' communication skills in elementary schools. The research objective was to determine the effect of applying the PBL model assisted by interactive worksheets on students' mathematical communication abilities. This research is a quantitative research using quasi-experimental with a post-test-only design. The population of this study was all elementary school students. The sampling technique used non-probability, namely purposive sampling, in which two class IV samples were divided into two groups. The experimental group had 30 students treated by PBL model assisted by interactive worksheets, and the control group was not treated with 30 students. The instrument in this study was a test of mathematical communication skills on fractions. Before using the research instrument, it was tested through validation and reliability processes, then data analysis techniques were carried out to test the hypothesis by previously carrying out the requirements analysis test, namely the normality and homogeneity tests. The data obtained was calculated using the Levene Test with the SPSS 23.0 application with normal and homogeneous distribution results. The results of this study show the influence of the application of PBL models assisted by interactive worksheets on the students’ mathematical communication abilities in elementary schools.
