Abstract

The purpose of this study was to measure the effectiveness of the open-ended approach assisted by the Genially platform on students' mathematical problem-solving abilities. The research method used was quantitative with an experimental method. The design used was Quasi Experimental with a Non-equivalent Pretest-Posttest Control Group Design. The sampling technique used was purposive sampling, with two classes divided into one experimental class of 36 students who received the treatment and one control class of 36 students who did not receive the treatment. The total sample in this study was 72 students. The instruments used in the study were test questions (pretest & posttest) on mathematical problem-solving skills and a questionnaire. The data analysis techniques used were the independent sample t-test, the Mann-Whitney U test, N-Gain analysis, and questionnaire processing. The analysis of initial ability showed a Sig. (2-tailed) value of 0.482 ≥ 0.05. Therefore, there was no significant difference in the initial mathematical problem-solving ability of the students. After both classes were given different treatments, the results showed Sig. (2-tailed) 0.000 ≤ 0.05, indicating a significant difference in problem-solving ability between the control class and the experimental class. The questionnaire results showed that the students gave positive responses and demonstrated high interest. The open-ended approach and the Genially platform are effectively used in mathematics learning to enhance students' mathematical problem-solving skills.

Abstract

Mathematical critical thinking is one of the essential competencies students must possess to face the challenges of the 21st century. However, the 2022 PISA results show that Indonesian students’ mathematical abilities are still relatively low. A preliminary study at SMP Negeri 3 Kuningan also revealed low levels of students’ critical thinking skills, as indicated by difficulties in analyzing and solving mathematical problems. This study aims to examine the effectiveness of Math Adventure media with a STEM (Science, Technology, Engineering, and Mathematics) approach on students’ mathematical critical thinking skills. The research employed a quantitative method with a quasi-experimental design of the non-equivalent control group type. The sampling technique used was purposive sampling, involving two classes as samples: the experimental class using Math Adventure based on STEM, and the control class using conventional learning methods. Research instruments consisted of tests (pretest and posttest) and a student response questionnaire. Data analysis was conducted using normality tests, homogeneity tests, t-tests, and N-gain analysis. The results showed a significant difference and improvement in students’ mathematical critical thinking in the experimental class. Student responses to the learning media were also very positive. Thus, Math Adventure media with a STEM approach is effective in improving students’ mathematical critical thinking skills.

Abstract

Mathematics is a field of study that requires students to continuously develop a deep understanding of concepts, thereby enhancing their conceptual comprehension skills. This study aims to examine and measure the effectiveness of the TPACK-based Cabri 3D learning media integrated into the Problem-Based Learning (PBL) model in improving students’ understanding of geometric concepts at SMK Negeri 1 Kuningan. The sampling technique employed was purposive sampling, where from the population of the Light Vehicle Engineering (Automotive) Department, class XI TKRO 1 was selected as the experimental group and class XI TKRO 3 as the control group. This research utilized an experimental method with a nonequivalent control group design. Prior to testing the hypothesis regarding differences in conceptual understanding improvement between the experimental and control classes, normality and homogeneity tests were conducted on the N-gain scores of each class. The normality test using the Shapiro-Wilk method indicated that the data were normally distributed, while the homogeneity test showed that the data were not homogeneous. Consequently, as the assumptions for a parametric test were not met, hypothesis testing was carried out using the nonparametric Mann-Whitney U test. The results revealed that the calculated t-value exceeded the critical t-table value, leading to the rejection of H₀, which indicates a significant difference in students’ conceptual understanding between the experimental and control groups. This finding suggests that the TPACK-based Cabri 3D learning media is effective in enhancing students’ conceptual understanding. Moreover, the questionnaire results showed positive student responses, indicating that the use of such learning media also fosters greater student engagement in the learning process.

Abstract

This study aims to explore and measure the effectiveness of using GeoGebra application-based STEM learning media in improving the mathematical problem solving ability of junior high school students. In this study, researchers took samples of two classes which will be divided into one control class and one experimental class. The class chosen as the control class is VII B and the experimental class is class VII E. With the experimental method, the two classes are divided into an experimental group (using GeoGebra) and a control group (conventional learning).  The research instruments used are in the form of description questions and questionnaires, while the data analysis techniques used are descriptive and inferential statistical analysis. This study used independent simple t-test, N-Gain test, and questionnaire processing. The results of the analysis showed that there was no significant difference in initial abilities between the two groups. However, after treatment, there was a significant increase in mathematical problem solving abilities in the experimental group. This is proven from the results of the post-test and N-Gain test. Student responses to the use of GeoGebra in learning mathematics with a STEM approach are also positive, showing high interest and understanding. These results support learning approaches that integrate technology and natural sciences, engineering, technology, and mathematics to improve students' mathematical problem solving skills
