Abstract

This study aims to analyse students' ability to understand and solve data processing problems, especially on mean (average), median (middle value), and mode (most frequently occurring value). The form of research used is descriptive qualitative with data collection techniques in the form of observation and in-depth interviews and documentation. analysis techniques using the Miles and Huberman interactive model. The results showed that students had understood the basic concept of median and were able to solve problems independently with good accuracy. On mean material, students have an understanding of the concept but still need encouragement and direction from the teacher in the process of solving problems, especially when facing more data and more complex work steps. On mode, students can identify the most frequently occurring value correctly but have not been able to think analytically so that the answers given are still inaccurate. The interactive and contextual learning process proved effective in helping APs deepen their understanding of concepts and improve their critical and analytical thinking skills. The implication of this finding is the need for reinforcement and continuous practice to increase APs' independence and confidence in solving data processing problems.Keywords: Contextual Approach, Mean, Median, Modus

Abstract

This study stems from the challenge of understanding the concept of SPLDV, which is generally still procedural and lacks meaning, as well as the diversity of students' initial abilities that influence their thinking processes and problem-solving strategies. The research method used was qualitative descriptive within the framework of Didactical Design Research (DDR) at SMP Muhammadiyah 5 Surakarta with three ninth-grade students representing high, medium, and low initial abilities as subjects. Data were collected through SPLDV concept comprehension tests and in-depth interviews. The results showed that the application of RME-based HLT helped students understand concepts gradually, starting from real contexts, situational models, mathematical models, to formal representations. Students with high initial abilities were able to fulfill all of Polya's problem-solving indicators, including the evaluation stage. Students with medium initial abilities were able to understand the problem and develop a plan but were not consistent in evaluating the results. Meanwhile, students with low initial abilities were only able to identify basic information without being able to model or implement a solution strategy. Overall, RME-based HLT proved to be effective in facilitating differences in students' initial abilities and improving their understanding of SPLDV concepts through a structured and contextual learning path.
