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 research develops a game-based interactive learning media called Turnreative, which is valid, effective, and practical for improving students’ understanding of algebraic function derivatives. The development follows the ADDIE model (Analysis, Design, Development, Implementation, Evaluation). Data collection instruments include validation sheets, practicality sheets, pre-test and post-test questions, and interviews. The collected data were analyzed using descriptive quantitative and qualitative techniques to determine the validity, practicality, and effectiveness of the media. The subjects were three public high school students in Palembang. Validation results showed the media was very valid, with scores of 82.5% from media experts and 89.5% from material experts. In terms of practicality, teachers gave 93.52% and students 93.33%. A small-scale trial indicated a significant increase in student understanding, from an average pre-test score of 33.33 to 90 in the post-test. The results conclude that Turnreative is feasible to use as a learning medium for algebraic function derivatives and has proven to be effective and efficient in enhancing students’ mathematical problem-solving skills.
