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 8th-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.

Abstract

Mathematics teaching needs to be carefully designed to promote complex cognitive skills, especially critical thinking skills, as an essential competence. However, the lecture and question-and-answer models that are still widely used are often unable to develop these skills optimally. This circumstance highlights the need for innovative learning models that actively engage students and utilize technology, in line with the Merdeka curriculum. The purpose of this study is to investigate the effectiveness of the flipbook-based model of PBL in improving students' mathematical critical thinking skills. Flipbooks in PBL provide a contextualized, visual, and student-centered approach that encourages collaboration, exploration, and reflection. The results of the Mann-Whitney hypothesis tests, as the data were not normally distributed and did not meet the requirements for a t-test, showed that students in the flipbook-based PBL group achieved a higher mean score than the lecture and question-answer model groups. The effect size (d) value of 1.01 is in the high category, indicating that this model has a positive impact on improving critical mathematical thinking skills and supports contextualized and collaborative learning.
