Abstract

The research was conducted to design and develop MaCo (Math Comics) learning media based on Realistic Mathematics Education (RME) which is expected to have the characteristics of validity, practicality, and effectiveness in improving learning outcomes and motivating students at the Senior High School (SMA) level. This research applies the ADDIE development model which consists of five main stages, namely Analysis, Design, Development, Implementation, and Evaluation. The results of material validation by material experts showed a percentage of 94% and 92%, while validation by media experts showed a percentage of 92% and 98% which were all included in the very valid category. After going through a revision process based on input from experts, the learning media developed was then tested on grade XI students at SMA Muhammadiyah 3 Jember to evaluate its effectiveness and practicality in supporting the learning process. Based on the results of the students' response questionnaire, a percentage of 86% was obtained which indicated that the learning media was included in the practical criteria. Furthermore, based on the comparison of pretest and posttest scores, an N-Gain value of 0.75 was obtained which was included in the criteria for high improvement in mathematics learning outcomes. While the N-Gain value for learning interest reached 0.55 which is included in the criteria for moderate improvement. Thus, it can be concluded that MaCo (Math Comics) media based on Realistic Mathematics Education (RME) is proven to meet the criteria of validity, practicality, and effectiveness, so it is feasible to be applied in the learning process to improve the quality and learning outcomes of students.

Review

This paper presents a compelling exploration into the development and evaluation of "MaCo (Math Comics)" learning media, specifically designed for Linear Programming within the Realistic Mathematics Education (RME) framework. The integration of an engaging comic format with a pedagogical approach that grounds mathematics in real-world contexts is a timely and promising strategy for enhancing student engagement and comprehension of often challenging abstract concepts. The research's adherence to the ADDIE development model, combined with strong initial validation percentages from both material and media experts, underscores a rigorous and well-structured approach to ensuring the foundational quality and design validity of the developed media. The study provides robust evidence for the MaCo media's practicality and effectiveness. With an 86% positive student response, the media clearly resonates with its target audience. More significantly, the substantial N-Gain value of 0.75 for mathematics learning outcomes indicates a high level of improvement, directly supporting the media's instructional efficacy. While the moderate N-Gain of 0.55 for learning interest suggests room for further enhancement in motivational aspects, it nonetheless demonstrates a positive impact on student attitudes. These findings collectively position MaCo as a demonstrably valid, practical, and effective educational tool, offering a tangible solution for improving the quality of teaching and student achievement in high school mathematics. While the abstract clearly outlines a successful development and initial evaluation, a full paper would benefit from deeper insights into certain aspects. For instance, a more detailed articulation of how specific RME principles were concretely translated into the comic narratives and problem scenarios would enrich the pedagogical discussion. Furthermore, while the study's focus on a single school provides valuable in-depth data, future research could explore the media's generalizability and effectiveness across a broader range of educational settings and student demographics. Nonetheless, this research provides a strong foundation and an encouraging proof-of-concept for an innovative and impactful approach to mathematics education, warranting further exploration and potential widespread adoption.
