Abstract

Mathematical reasoning skills are an important aspect of mathematics learning that needs to be developed from an early age. This study aims to analyze the mathematical reasoning ability of grade VII junior high school students in set materials with a qualitative descriptive approach. The research subjects were selected purposively based on varying levels of mathematical ability (high, medium, and low). Data was collected through mathematical reasoning tests and semi-structured interviews to dig into students' thought processes. The test instruments are arranged based on mathematical reasoning indicators. The results showed that 43.75% of students were in the good category, 43.75% in the fair category, and 12.5% in the low category. These findings indicate that most students have been able to display adequate mathematical reasoning, although there are still weaknesses in drawing conclusions and making mathematical guesses. The implications of this study emphasize the importance of designing adaptive and contextual learning strategies, as well as the need for the integration of cognitive and affective approaches to improve the quality of students' reasoning in mathematics learning.

Abstract

This study aims to produce a product in the form of a Canva-based teaching e-module to facilitate creative thinking skills in algebraic form material. This study uses a Research and Development (R&D) approach with stages, namely potential and problems, data collection, product design, design validation, design revision, product testing, product revision, and final product. In the data collection process, researchers used several instruments in the form of validation sheets addressed to experts, as well as practicality questionnaires intended for teachers and students. The objects of this study were eighth grade students at the junior high school level. Based on the development results, it was obtained that the learning media in the form of teaching e-modules designed by using the Canva platform showed validation results with an average percentage value of 85.47% with valid criteria. Meanwhile, the practicality value obtained from the teacher's practicality questionnaire was with an average percentage of 87.5% with very practical criteria, and the student's practicality questionnaire with an average percentage value of 88.89% with very practical criteria. Thus, the results of the research and development of Canva-based teaching e-modules for creative thinking skills in algebraic form material for junior high school students can be concluded that from the validation results by experts and responses from teachers and students, the developed learning media is declared suitable for use in the learning process. Keywords : e-learning module, Canva, creative thinking.
