Abstract

This study aims to determine students' problem-solving abilities in solving open-ended problems in social arithmetic. Problem-solving ability refers to students’ capacity to understand problems, plan appropriate strategies, carry out solutions, and evaluate the results. The research method used in this study is descriptive with a qualitative approach. Data collected in this study were taken from problem-solving ability test results and interviews. The study subjects were seventh-grade students of SMP Negeri 1 Botupingge in the 2025/2026 academic year, each of whom was selected using purposive sampling based on their high, medium, and low problem-solving ability levels. The obtained data were then reduced and analyzed qualitatively, taking into account indicators of the problem-solving ability process. The results show that students with high problem-solving abilities demonstrated excellent problem-solving abilities across almost all indicators. Meanwhile, students with moderate problem-solving abilities were at a sufficient level but were not yet stable and still required guidance, especially in planning and interpreting solutions. Meanwhile, students with low problem-solving abilities had not yet mastered problem-solving skills and required intensive learning intervention.

Abstract

This study aims to improve mathematics learning outcomes through the implementation of the Contextual Teaching and Learning (CTL) learning model online and susdut material in grades VII-6 of SMP Negeri 1 Tapa totaling 20 people using the class action research method.  The data collection techniques used in this study are teacher conservation, student observation and student learning outcomes covering three domains, namely affective, psychomotor, and cognitive shutter. The results of data analysis showed an increase in mathematics learning outcomes in the good and very good categories with a percentage of 87.50% for teacher activities, 89.47% for student activities, and for learning hasl each affective domain reached 89%, psychomotor realm 85% and affective realm 90%. The implication of this research is that it needs the implementation of the Contextual Teaching and Learning (CTL) learning model in improving mathematics learning outcomes.
