Abstract

The aim’s of this research is to determine the increase in students' mathematical problem solving abilities using the discovery learning model. The research method used uses quasi-experimental techniques. The subjects of this research were 30 students at Kahuripan Lembang Middle School, class VIII-C. Data collection techniques through test questions and LKPD with discovery learning model stages. The data obtained was then analyzed quantitatively using the difference between two means test. The results of the research show that students' mathematical problem solving abilities use the discovery learning model for class VIII middle school because the learning activities carried out make students think more systematically, critically, creatively in solving the problems given, so that they can improve students' mathematical problem solving abilities.

Abstract

The aim of the research is to find out whether there is an increase in students' mathematical reasoning abilities with the discovery learning learning model compared to ordinary learning. The method used was quasi-experimental with a non-equivalent pretest-posttest design. The population in this study were class VIII students at SMP PGRI 1 Cimahi. The sample in this study was 30 students from class VIII-C and class VIII-D for each class. Class VIII-C is used as an experimental class and class VIII-D is used as a control class. The data collection technique in this research was through a written test consisting of six descriptive questions. The data obtained will be analyzed and processed with the help of IBM SPSS version 26 for Windows software. Based on the research results, H_0 was rejected and H_1 was accepted, meaning that there was an increase in the mathematical reasoning abilities of students whose learning used regular learning. Thus it can be concluded that there is an increase in mathematical reasoning abilities in the experimental class which uses the Discovery Learning Learning Model.

Abstract

This study aims to develop an interactive learning media, STECU, assisted by VBA Excel within a challenge-based learning framework in enhancing students’ mathematical creative thinking ability. The method used was R&D on the ADDIE model stages. The participants included 6 students in the one-to-one trial, 20 students in the small group trial, and 35 students in the field trial. The implementation phase involved 33 students in the control class and 33 students in the experimental class at a junior high school in Cimahi. Data were collected through validation sheets, observations, interviews, response questionnaires, preliminary studies, and test instruments. Data analysis was conducted using descriptive and inferential statistics, including N-gain calculations. The findings indicate that the developed media achieved high validity, with scores of 96.59% for media aspects and 95.56% for material aspects. The practicality results showed excellent ratings across trials, with percentages of 87.50%, 89%, and 90.48%, respectively. Furthermore, the effectiveness analysis revealed that the experimental class achieved a higher N-gain 0,77 compared to the control class 0,53. These results suggest that the STECU media effective in improving students’ mathematical creative thinking ability.
