Abstract

This research aims to find out whether the application of the problem based learning model can improve students' mathematical problem solving abilities in class VII of St. Peter's Middle School, Medan. This research method uses Classroom Action Research (PTK). The research procedure is cyclical. Each cycle consists of 4 stages, namely: planning, implementing actions, observing and reflecting. Data collection techniques through observation and tests. This data collection uses several instruments in the form of student observation sheets. Meanwhile, to determine students' mathematical problem solving abilities, tests are used. The results of the research show that the use of the Problem Based Learning learning model can improve students' mathematical problem solving abilities in mathematics lessons on algebra material. From the average value of prerequisite abilities, namely 55.56, the average value of students' mathematical problem solving abilities in cycle I is 72.55 and the average value of students' mathematical problem solving abilities in cycle II is 76.39 and the activity value of students in cycle I is 62%, and cycle II, namely 85%.

Abstract

This study evaluates the practicality of a Realistic Mathematics Education model integrated with Batak Toba cultural elements to develop Higher-Order Thinking Skills among pre-service elementary school teachers. Using a Research and Development (R&D) design based on Plomp’s three-phase model, the research involved preliminary investigation, design and development, and evaluation. The model was validated through expert judgment, pilot testing, and classroom trials. Practicality was assessed using indicators of implementation, ease of use, student engagement, and practitioner acceptance. Results from two trials showed significant improvements: implementation increased from 3.2 to 4.5, lecturer ease from 3.1 to 4.4, student engagement from 3.0 to 4.3, and practitioner acceptance from 3.3 to 4.6 (scale 1–5). Students’ HOTS improved from a moderate category (0.63) in the first trial to a high category (0.85) in the second. These findings indicate that the Batak Toba culture-based RME model is practical, culturally relevant, and pedagogically effective, with strong potential for integration into teacher education programs.
