Abstract

This study aims to determine the effect of project-based learning on students' conceptual understanding abilities in the topic of cylindrical three-dimensional shapes in junior high school. The type of research used is quasi-experimental with a pretest-posttest control group design. The research subjects consisted of 64 students, divided into an experimental class and a control class, each comprising 32 students. The research instrument was a conceptual understanding ability test consisting of essay questions. The data were analysed using the Shapiro-Wilk normality test, Levene's Test for homogeneity, and the independent two-sample t-test. The results showed that the posttest data of both classes were normally distributed and had homogeneous variances. The t-test indicated a significant difference between the conceptual understanding abilities of students in the experimental and control classes (Sig. = 0.006 < 0.05), with the experimental class posttest mean being higher. This indicates that project-based learning is effective in enhancing students' conceptual understanding skills. Project-based learning provides contextual learning experiences, encourages active student engagement, and strengthens meaningful understanding of mathematical concepts.

Abstract

This study aims to describe the use of keteng-keteng musical instruments as a medium for teaching mathematics on the subject of curved tube shapes in ninth grade junior high school. The study uses a descriptive qualitative approach with ninth grade junior high school students as the research subjects. Data collection was carried out through observation of the learning process, interviews with students and teachers, and documentation of learning activities. Data analysis was carried out through the stages of data reduction, data presentation, and conclusion drawing using triangulation techniques to maintain data validity. The results showed that the use of keteng-keteng musical instruments helped students understand the concept of cylinders more concretely through direct observation of the shape, elements, and characteristics of cylinders. In addition, the use of this locally-based media was able to increase student engagement, interest in learning, and activity in the mathematics learning process. Thus, the keteng-keteng musical instrument can be used as an alternative contextual and meaningful learning media for mathematics in the subject of curved tube shapes.

Abstract

This study aimed to determine the effect of project-based learning on students’ conceptual understanding of plane geometry at Bintang Laut Private Elementary School, Telukdalam. The study employed a quantitative approach using a quasi-experimental method. The research subjects were fifth-grade students divided into an experimental group and a control group. The experimental group was taught using the project-based learning model, while the control group received conventional instruction. The research instrument was a conceptual understanding test on plane geometry administered before and after the treatment (pretest and posttest). The collected data were analyzed using descriptive and inferential statistics to identify differences in students’ conceptual understanding. The results revealed a significant improvement in students’ conceptual understanding in the experimental group after the implementation of project-based learning compared to the control group. Students taught through project-based learning demonstrated better abilities in understanding the properties of plane figures, applying formulas for area and perimeter, and relating mathematical concepts to real-life situations. These findings indicate that project-based learning is effective in enhancing elementary school students’ conceptual understanding of mathematics. Therefore, project-based learning is recommended as an innovative and contextual instructional strategy in elementary mathematics education.
