THE EFFECT OF THE PROBLEM-BASED LEARNING MODEL ASSISTED BY QUESTION CARD MEDIA ON MATHEMATICS LEARNING OUTCOMES

2025-10-15T22:11:54+07:00

This study aims to examine the effect of the Problem-Based Learning (PBL) model supported by question card media on students' mathematics learning outcomes. The research employed a quasi-experimental design involving fourth-grade students at SD Negeri Margajaya 4, with a total sample of 48 students selected through purposive sampling. Data on students' learning outcomes were collected using pre-tests and post-tests. To analyze the data, several statistical tests were conducted, including the N-Gain test, normality test, and homogeneity test as prerequisites before performing the hypothesis test (t-test). The average N-Gain score in the experimental class was 70, while the control class scored 59. Hypothesis testing using the t-test showed that the calculated tvalue (3.32929) exceeded the critical t_value (2.01290) at a 5% significance level. This result indicates that the null hypothesis (H0) is rejected and the alternative hypothesis (Ha) is accepted. Based on these findings, it can be concluded that the implementation of the Problem-Based Learning model assisted by question card media has a significant positive effect on students’ mathematics learning outcomes. The integration of interactive media within a student-centered learning model enhances engagement and improves academic achievement in mathematics.

2025-10-15T22:11:33+07:00

This study was motivated by the low level of understanding among elementary school students, particularly those in fifth grade, regarding the topic of plane figures in mathematics. This condition highlights the need for innovative learning media that can enhance students’ active participation in the learning process. The primary objective of this research is to develop an interactive learning medium called SUSI (Susun Sisi), specifically designed to facilitate students’ comprehension of plane figure concepts in an engaging and accessible manner. The research adopts a Research and Development (R&D) approach using the ADDIE model, which includes five systematic phases: analysis, design, development, implementation, and evaluation. The study involved one instructional media expert and 30 fifth-grade students as research subjects. The instruments employed consisted of expert validation sheets and student response questionnaires. Data were collected through expert validation and limited trials with students, then analyzed quantitatively. The results indicate that the SUSI learning media was rated valid by experts with a score of 84%, and was perceived as highly practical by students, achieving a practicality rate of 93.14%. Therefore, the SUSI media is deemed suitable for use in mathematics instruction and is recommended for classroom implementation by educators.

PERAN KONSEP MATEMATIKA DALAM PLATFORM DIGITAL: PERSPEKTIF MAHASISWA

2025-10-15T22:12:13+07:00

The advancement of digital technology has positioned mathematical concepts as fundamental components in the operation of various digital platforms, including search engines, social media, and e-commerce systems. This study aims to investigate the extent to which university students comprehend and recognize the integration of mathematicsparticularly logic, algorithms, and statistics within the digital tools they engage with daily. Employing a descriptive quantitative method, data were collected through an online questionnaire involving 66 students from multiple academic disciplines. The results indicate that while most participants acknowledge the presence of mathematical elements in digital systems, their understanding of the underlying processes remains limited. The primary barriers identified include insufficient mastery of foundational mathematical concepts and the lack of instructional approaches that explicitly connect mathematics to digital technologies. Nevertheless, a substantial proportion of students express strong interest in learning mathematics in more practical and technology-oriented contexts. These findings underscore the need for pedagogical strategies that contextualize mathematical theory within real-world digital environments, thereby enhancing students’ digital numeracy and analytical capabilities.

PENGEMBANGAN VIDEO PEMBELAJARAN BERBASIS APLIKASI GOOGLE SKETCH UP PADA MATERI SMA

2025-10-15T22:12:51+07:00

This study aims to develop a practical learning video media based on the Google SketchUp application for high school subjects. The research employs a Research and Development (R&D) method consisting of three main stages: defining, designing, and developing. In the defining stage, the researcher conducts a needs analysis and interviews with teachers, as well as analyzes the material in accordance with the applicable curriculum. The designing stage involves creating an engaging and systematic concept for the learning video using the Google SketchUp application, complemented by animations and other multimedia elements. The development stage involves producing the learning video product, which is then tested and validated by media experts and material experts. The research subjects consist of two media experts, two material experts, and 27 high school students who participate in a small group trial to measure the practicality of the developed media. Validation results show that the learning video received a 79% score from media experts, indicating that the media is feasible to use, and 81.53% from material experts, indicating that the media is highly feasible. Furthermore, the practicality test with students yielded a score of 87.74%, indicating that the media is very practical for use in the learning process. Based on these validation and practicality results, it can be concluded that the learning video media based on the Google SketchUp application is effective and feasible as a learning tool at the high school level.

ANALISIS KESULITAN SISWA PADA MATERI MATRIKS DI KELAS XI SMA SWASTA AL MAKSUM

2025-10-16T12:53:02+07:00

This study aims to investigate the difficulties experienced by students in understanding matrix material, with a particular focus on matrix multiplication. The research was conducted with 13 students from grade XI of Al Maksum Private High School Medan. To obtain comprehensive data, researchers used a combination of interviews and written tests. These instruments were designed to explore students’ conceptual understanding as well as the procedural aspects of solving matrix problems. The data collected were then analyzed using the Miles and Huberman model, which involves three key steps: data reduction, data display, and drawing conclusions. The results of the analysis revealed that students encountered various obstacles in learning matrices, especially in performing matrix multiplication. The main difficulties stemmed from several factors, including a lack of understanding of the basic concepts and rules that govern matrix operations, particularly multiplication. Additionally, many students made calculation errors, especially when dealing with positive and negative numbers. Some students also demonstrated low confidence in their answers, which may have led them to second-guess correct solutions. Moreover, insufficient attention to detail when performing step-by-step calculations often resulted in inaccurate final answers. These findings highlight the importance of reinforcing conceptual understanding, improving arithmetic accuracy, and building students’ confidence through targeted instructional strategies and practice. Such improvements may help students overcome their current learning obstacles in matrix-related topics.
