Abstract

Character education plays an important role in shaping individuals who not only excel academically but also possess strong morals and high social values. In the context of mathematics learning, character values not only help students understand numerical concepts but also instill discipline, hard work, and perseverance. This study aims to analyze the implementation of character values in mathematics learning and the role of teachers in developing them. The subjects of the study were 100 high school students from public schools in Palembang. Data were collected through questionnaires and interviews and analyzed using descriptive methods. The results showed that the values of discipline, hard work, and religiosity were dominant, while creativity and communication remained weak. Therefore, efforts are needed to develop these values, particularly creativity and communication, through improved teacher professionalism, interactive learning, integration of real-world contexts, and addressing students' psychological barriers.

Abstract

This study aims to develop the Magic Cube, an innovative manipulative learning medium designed to improve students’ conceptual understanding of number patterns. Number patterns are essential for building mathematical reasoning and problem-solving skills, yet many students struggle due to abstract teaching methods that lack interactive components. Previous studies have highlighted the effectiveness of game-based learning, but there remains a research gap in developing tangible and engaging media that directly support students’ comprehension. To address this, the study applied a Research and Development (R&D) approach using the ADDIE model, consisting of five stages: analysis, design, development, implementation, and evaluation. The Magic Cube, designed as a three-dimensional cube equipped with material and question cards, was validated by two media experts and two material experts, achieving validity scores of 86% and 73%. Practicality tests involving teachers and students resulted in scores of 84.83% and 86.6%, respectively. Furthermore, pre-test and post-test results showed a significant improvement in students’ conceptual understanding, with an N-Gain score of 0.7, categorized as high. These findings indicate that the Magic Cube is a valid, practical, and effective instructional tool. The study contributes to enhancing interactive mathematics learning and provides broader implications for fostering active engagement and improving students’ comprehension of abstract mathematical concepts.

Abstract

This study aims to develop teaching methods that are effective, supportive, and efficient in enhancing students' understanding of mathematical concepts. The research followed the ADDIE development model, which consists of five phases: analysis, design, development, implementation, and evaluation. The study was conducted in response to students' difficulties in understanding trigonometric concepts and recent advancements in educational media identified by researchers. The feasibility and usability of the instructional tool was assessed by both teachers and students. Its validity was evaluated by involving media and content experts. A descriptive analysis was then performed on data collected through observations and interviews conducted throughout the research process. The results of the validity assessment showed scores of 89.29% from content experts and 80.58% from media experts, indicating that the instructional tool is highly suitable for classroom use. The evaluation form revealed scores of 90% from teachers and 78.72% from students, suggesting that the tool is considered very practical. Furthermore, an analysis of student performance demonstrated that Kipas MATHIC effectively enhances students’ understanding of trigonometric concepts.
