Abstract

In the era of globalization, the 21st century requires learning integrated with technological developments and innovation. This study aims to analyze the implementation of the Connecting, Organizing, Reflecting, Extending (CORE) learning model based on the Geogebra Applet on students' critical thinking ability regarding learning styles. The design of this study is quasi-experimental. The samples in this study were students of class XI MIPA 1 and XI MIPA 2 SMA Negeri 2 Magelang who were selected by the cluster random sampling technique. The instruments used in this study were critical thinking ability tests and learning style questionnaires. Based on the results of the hypothesis test conducted with the ANOVA test of two unequal cell paths and the LSD (Least Significance Difference) follow-up test, results were obtained:  (i) The Core learning model based on the Geogebra Applet produces students' critical thinking ability better than the direct learning model; (ii) There are differences in critical thinking ability between students and the learning styles of divergers, convergers, assimilators and accommodators; (iii) There is no interaction between the Geogebra Applet-based CORE learning model and the direct learning model with the student's learning style.

Abstract

This study examines the effectiveness of the Connected Mathematics Project (CMP) learning model in improving students' mathematical communication skills at MA Madarijul Huda Pati. Because of 46.15% of students demonstrating very low skills and 23.07% falling into the low category, the study aims to: (1) analyze the impact of CMP on mathematical communication skills, (2) compare skills among students with high, moderate, and low self esteem, and (3) explore the interaction between CMP and self esteem. Employing a quantitative quasi-experimental approach, the study involves class XI students selected through cluster random sampling. Results indicate a significant improvement in mathematical communication skills through CMP. Students with high self esteem outperform those with moderate self esteem, while those with moderate self esteem fare better than those with low self esteem. Additionally, students with high self esteem exhibit superior mathematical communication skills compared to students with low self esteem. Notably, an interaction between the learning model and self esteem was observed, influencing mathematical communication skills.
