Exploring measurement estimation strategies through concept cartoons designed with Realistic Mathematics Education

Concept cartoons, in relationship with Realistic Mathematics Education (RME), not only serve as a dynamic platform for problem-solving but also intricately weave mathematical concepts into the fabric of real-world scenarios, creating a harmonious fusion of theory and practical application. By using relatable characters and presenting ideas through engaging narratives, students are encouraged to tackle problems within the given context. The aim of this study was to investigate the measurement estimation strategies used by students when exposed to concept cartoons specifically designed for RME. A qualitative research methodology was followed, involving 46 fourth-grade students from a primary school. The data collection instrument utilized was “RME-Supported Concept Cartoons.” Descriptive analysis was employed to analyze the collected data. The concept cartoon activities incorporated measurement estimation strategies such as prior knowledge, unit iteration/separation, segmentation/chunking, and comparison, which students could potentially prefer. However, it was observed that students predominantly utilized division into unit iteration/separation and segmentation/chunking strategies over other estimation strategies. Furthermore, the frequency of strategy use did not exhibit significant variations based on gender. When examining the strategies developed by the students, it is noteworthy that the presence of “another solution-oriented option” and “irrelevant answers” was prominent.
