Abstract

Mathematics plays an important role in developing logical, critical, creative, and systematic thinking skills, but it is often considered difficult and boring, requiring innovative learning media. One of the most challenging topics is reflection because of its abstract nature and the need for visualization skills. This study aims to develop interactive media based on Nearpod that is valid, practical, and effective. The method used is Research and Development (R&D) with the 4D model (Define, Design, Develop, Disseminate) and a one-group pretest–posttest design on 35 students in grade XI at Karawang State Senior High School 6, who were selected using purposive sampling. Data were obtained through validation questionnaires, practicality questionnaires, and learning outcome tests. The results showed that Nearpod media was rated as very feasible by media experts, with an overall average score of 3.90. It was also rated as very feasible by subject matter experts, with an overall average score of 3.80, and by students, with an overall average score of 3.85. In terms of practicality, it was categorized as highly feasible based on the results of the teacher questionnaire assessment with an overall average score of 3.60, while based on the student questionnaire assessment, it was categorized as feasible with an overall average score of 3.44. Thus, Nearpod is proven to be valid and practical for use in reflection material.

Abstract

This study aims to determine the differences in students' geometric reasoning in terms of Van Hiele's thinking levels in spatial geometry. This study used an ex post facto method with a quantitative approach. The population of this study was ninth-grade female students at SMP Negeri 2 Majalaya, with a sample of 86 students selected using simple random sampling. Data were obtained through diagnostic tests, geometric reasoning tests, and unstructured interviews with several samples. This study uses several inferential statistical tests such as normality tests, homogeneity tests, and ANOVA. The results of this study indicate that there are significant differences between the geometric reasoning abilities of students at level 0 and level 1, as well as between level 0 and level 2. The number of students classified as level 0 (visualization) is 69.77%; level 1 (analysis) is 24.42%; and level 2 (informal deduction) is 5.81%. No students were classified as level 3 or 4.

Abstract

This study aims to analyze students' mathematical problem-solving abilities in Single Variable Linear Equations and the Pythagorean Theorem based on Polya's problem-solving stages. The study uses a descriptive qualitative approach involving 40 eighth-grade students VIII junior high school students through descriptive tests and interviews. The results of the analysis show that students' mathematical problem-solving abilities are in the moderate category for both subjects, with an average score of 74.85 for Single Variable Linear Equations and 74.67 for the Pythagorean Theorem. Students in the high category are able to go through all stages of problem solving systematically. Students in the moderate category were able to understand the problem and plan a solution strategy, but often made computational errors. Conversely, students in the low category had difficulty understanding information, constructing mathematical models, and implementing solution procedures. Overall, the results of this study confirm the need to strengthen problem-solving-based learning that emphasizes understanding concepts and solution strategies to optimally improve students' mathematical problem-solving abilities.
