Abstract

This study aimed to evaluate the level of proportional reasoning among middle school students in their ability to solve mathematical problems involving proportions. Proportional reasoning is essential for understanding and mastering various mathematical concepts, serving as a fundamental skill for higher-level mathematics. A qualitative case study design was employed, involving 28 eighth-grade students from a school in Bandung, Indonesia. The participants were assessed using a set of proportion-related problems, including numerical comparison, non-proportional (additive), direct proportion, and inverse proportion tasks. The analysis focused on categorizing the students' problem-solving strategies into distinct levels of proportional reasoning, ranging from non-proportional to formal proportional reasoning. Additionally, three students representing high, moderate, and low mathematical performance were selected for in-depth interviews to explore their reasoning processes when addressing proportion problems. Data analysis included administering tests, reviewing students' problem-solving strategies, conducting in-depth interviews, and evaluating their proportional reasoning abilities. The findings revealed that students with high and moderate mathematical performance exhibited proportional reasoning levels ranging from 0 to 3, whereas low-performing students displayed levels ranging from 0 to 2. Moreover, students generally faced difficulties distinguishing between proportional and non-proportional problems. Even when correct answers were provided, many lacked a deep understanding of direct and inverse proportion concepts. The study also discusses several implications for enhancing students' proportional reasoning skills.

Abstract

Pengaruh Media Sosial Terhadap Wawasan Kebangsaan Pada Generasi Muda adalah bahwa media sosial dapat mempengaruhi wawasan kebangsaan pada generasi muda. Penggunaan media sosial dapat memperkuat atau merusak wawasan kebangsaan, tergantung pada bagaimana penggunaannya. Oleh karena itu, penting bagi generasi muda untuk memiliki literasi media yang kuat dan penggunaan media sosial yang sehat dan bijak agar dapat memperoleh wawasan kebangsaan yang positif dan inklusif. Perlu adanya upaya kolaborasi antara lembaga pemerintah, sekolah, dan organisasi masyarakat sipil untuk memperkuat literasi media dan edukasi penggunaan media sosial yang sehat, sehingga generasi muda dapat lebih memahami dan menyadari dampak dari penggunaan media sosial terhadap wawasan kebangsaan.
