Abstract

This study aims to determine the effect of blended learning strategies on the creativity of the pre-service teachers. By a quantitative approach, the type used in this study is a quasi-experimental with pretest-posttest control group design. The population in this study were pre-service teachers in semester VII of the Mathematics Education Study Program at Universitas Negeri Medan. The instrument has used a test in the form of essay tests of 5 items concerning creativity. The results of the study indicated that there were significant differences in the creativity of pre-services teachers who apply blended learning and direct learning. Thus, it could be concluded that blended learning gave effects of creativity.

Abstract

The purpose of this study was to determine the improvement of students' mathematical reasoning abilities by applying the Geogebra-assisted Project Based Learning learning model in class VIII-1 MTs Nurul Islam Indonesia Medan in the 2022/2023 academic year. The subjects in this study were students of class VIII-1 MTs Nurul Islam Indonesia Medan, amounting to 20 people. The data collection techniques used were teacher observation sheets, tests of mathematical reasoning abilities and documentation. This research is a classroom action research (CAR) which consists of 2 cycles, each cycle consists of 2 meetings. Before taking the action, an initial test is given and at the end of each cycle a student's mathematical reasoning ability test is given. The results of the students' mathematical problem reasoning ability test increased from the initial test, cycle I, and cycle II. In the classical initial test, 4 students (20%) completed and the average initial test ability was 56.29 with a very low level of ability category. In the classical first cycle test, 4 students (20%) completed and the average ability test was 57.22 with a very low level of ability category. Then in the second cycle test, classically, 17 students (85%) completed and the average ability was 89.44 with a high level of ability. Thus, it can be concluded that the application of the project based learning model assisted by the geogebra application to improve students' mathematical reasoning abilities at MTs Nurul Islam Indonesia Medan.

Abstract

This study is motivated by the presence of mistakes in solving Algebraic Structure problems, particularly on the topic of Ring. The purpose of this research is to analyze the mistakes made in solving Algebraic Structure problems, specifically on the topic of Ring at Universitas Negeri Medan. Mistakes are classified into conceptual errors, data usage errors, language interpretation errors, technical errors, and conclusion errors. The research method used is descriptive qualitative, involving three sixth-semester students of the academic year 2024/2025 with prior knowledge of the Ring topic. Data collection techniques included tests and open questionnaires. Data analysis was conducted through data reduction and categorization of error types. The results show various errors such as conceptual errors, technical errors, and conclusion errors. This research can serve as a recommendation for educators to be more proactive in assisting students in understanding the material through more effective and engaging teaching methods, as well as providing more in-depth training.
