The Effect Of The Use Of Online Geogebra Learning Media And Learning Style Categories On The Mathematical Communication Skills Of Junior High School Students

Abstract

This research aimed at testing, 1) whether there was a difference in mathematical communication skills of students in classes using Online GeoGebra and those not using Online GeoGebra; 2) whether there were differences in mathematical communication skills in terms of learning styles; 3) whether there was an interaction effect on students using Online GeoGebra and those not using Online GeoGebra and learning styles This research used a quasi-experimental design research method with a post-test only research design.  The population of this research consisted of 8^th-grade students with a total of 4 classes from of one of the Integrated Islamic Junior High Schools in Bekasi City. There were two groups for this research-the experimental group and the control group. The sample used consisted of two classes: one as The control class consisted 23 students and the other as the experimental class consisted 27 students. This research used two instruments: a questionnaire on learning styles and a test related to mathematical communication skills. Data analysis test using two-way ANOVA and Scheffe's multiple comparison test. The results of the research showed that, 1) there was a difference in mathematical communication abilities in classes using Online GeoGebra and those not using Online GeoGebra; 2) there were no differences in mathematical communication abilities in terms of learning styles; 3) there was an interaction between treatment and learning style on mathematical communication skills.
