Abstract

This study aims to determine the effect of implementing deep learning based on humanistic learning theory on the learning abilities of students at Methodist Kuala Private Junior High School. This study uses a quasi-experimental design with a pretest-posttest control group design. The research subjects consist of two classes, namely class VIII-1 as the experimental class and class VIII-2 as the control class, each consisting of 32 students. The research instrument consists of a learning ability test administered to both groups before (pretest) and after the intervention (posttest). The data obtained were analyzed using a t-test to examine differences in learning outcomes between groups, as well as N-Gain calculations to determine the level of improvement in learning ability. The results showed that the initial abilities of the two groups were relatively equal. However, after the treatment, the experimental class achieved higher posttest scores (M = 87.5; SD = 7.16) with an N-Gain of 0.71 (high category), compared to the control class (M = 82.3; SD = 7.37) with an N-Gain of 0.59 (moderate category). The t-test results showed a significant difference (p < 0.05) in learning outcomes after the treatment. These findings indicate that humanistic theory-based deep learning is effective in improving students' learning abilities while creating an empathetic and supportive learning environment.

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 aims to analyze the effect of deep learning on students' critical thinking skills in mathematics learning in grade XI high school. This study uses a quantitative approach with a quasi-experimental design involving one experimental class and one control class. Deep learning treatment was given to the experimental class, while the control class followed conventional learning. Data on critical thinking skills were collected through a validated posttest. Data analysis was performed using the Shapiro–Wilk test to test normality, the Levene test to test homogeneity, and the independent samples t-test to test the difference in means between the two groups. The results of the analysis showed a significance value of 0.000, which is less than 0.05, indicating a significant difference between the critical thinking skills of students in the experimental class and the control class. These findings indicate that deep learning has a positive and significant effect on improving students' critical thinking skills in mathematics learning.

Abstract

This study aims to determine the effect of implementing a Project Based Learning (PjBL) based learning module on students' creative thinking abilities in solid geometry material through the creation of a Batak Toba traditional building miniature in junior high school. This study uses a quantitative approach with a quasi-experimental design of the non-equivalent control group type. The research sample consisted of two classes, namely the experimental class that received treatment using the PjBL-based module and the control class that used conventional learning. Data collection techniques were conducted through pretests and posttests using mathematical creative thinking ability test instruments referring to indicators of fluency, flexibility, originality, and elaboration. Data were analysed through normality tests, homogeneity tests, and Independent Sample t-Test. The results show that the data are normally distributed and homogeneous. The hypothesis test obtained a significance value of 0.000 (< 0.05), indicating a significant difference between the creative thinking abilities of students in the experimental and control classes. Thus, the implementation of the PjBL-based learning module through a Batak Toba traditional building miniature project has proven effective in enhancing the mathematical creative thinking abilities of junior high school students
