Abstract

Various evaluation results indicate that students' mathematical critical thinking skills are still relatively low. This study aims to determine the effectiveness of using E-Worksheets based on Ethno-Modeling and Tri-N in improving the students’ mathematical critical thinking skills. This study uses a quantitative approach with a quasi-experimental method and a time series design. The research subjects consisted of 20 students selected using a purposive sampling technique. Data were collected through essay tests at each meeting and analyzed using descriptive statistical analysis, trend analysis, and data stability analysis. The results showed a gradual increase in the average value of students' mathematical critical thinking skills from the first to the last meeting with a tendency for an increasing and stable trend. The trend analysis showed a positive trend, while the stability analysis showed a data stability percentage of 88.9%, which is considered stable. These results indicate that the use of Ethno-Modeling and Tri-N-based E-Worksheets is effective in improving students' critical mathematical thinking skills.
