Analysis of Students' Mathematical Reasoning Ability with the Constructivism Approach through Mobile Learning System

Abstract

Aims: To analyze the mathematical reasoning ability of mathematics education students. Study Design: Qualitative research with a descriptive approach. Place and Duration of Study: The population of all 3rd-semester mathematics education students at Bung Hatta University who take geometry courses is 25 students. Methodology: This research is qualitative research with a descriptive approach. Researchers directly measure the mathematical reasoning ability of students in the mathematics education study program. Judging from the research subjects, the population of all 3rd-semester mathematics education students at Bung Hatta University who took geometry courses was 25 students. Results: From the analysis results, it was found that the achievement of mathematical reasoning abilities for indicators of students' ability to present mathematical statements orally, in writing, pictures, and diagrams indicated by question number 1 was 74% (Good Category). The indicators of mathematical manipulation ability shown in questions number 2 and 5 are 41% (Category Enough), and 42% (Category Enough). And the indicators of students' ability to conclude, compile evidence, provide comments, or evidence from several solutions shown by questions number 3 and 4 are 67% (Good Category) and 58% (Enough Category). Conclusion: The conclusion of this study is to be able to determine the category of mathematical reasoning of the 3rd-semester students of the Bung Hatta University Mathematics Education Study Program.
