Abstract

This study aims to describe the implementation of the Search, Solve, Create, and Share (SSCS) learning model in improving the mathematical problem-solving abilities of seventh-grade students at SMP Negeri 1 Sindue Tombusabora. This research is a Classroom Action Research (CAR) using the Kemmis and McTaggart design, which consists of four stages: planning, action, observation, and reflection. The research subjects were 20 students of class VII A, with three students selected as informants. The research was conducted in two cycles. Based on the final action test results, the percentage of classical learning mastery increased from 60% in the first cycle to 88.23% in the second cycle. Teacher and student observations also improved from a good category in the first cycle to a very good category in the second. The SSCS model was implemented through several phases: (1) introduction, where prior knowledge was explored through discussion; (2) search, where contextual problems related to real-life situations were introduced; (3) solve, where students analyzed information to identify patterns and draw preliminary conclusions; (4) create, where students formulated solutions in the form of simple posters; (5) share, where students presented their results in front of the class; and (6) conclusion, where students and the teacher reflected together. The findings indicate that the SSCS model effectively enhances students' mathematical problem-solving skills.

Abstract

This research aims to describe students' problem solving profiles in solving story problems adding and subtracting integers based on learning styles (visual, auditory and kinesthetic) using the Polya approach. This research uses a qualitative approach with descriptive methods. The research subjects consisted of three class VII students at SMP Negeri 2 Palu, each of whom represented a visual, auditory and kinesthetic learning style. The results of the research showed that students with a visual learning style did not fully understand the problem according to the Polya procedure, even though they could state some of the information in words. -said himself. Subjects prepare plans logically and carry out steps systematically, but do not double-check the results so that there are errors that are not corrected. Students with an auditory learning style can understand problems completely and formulate plans by adding up information based on time sequence. Subjects executed plans consistently but did not thoroughly double-check results, resulting in errors being left uncorrected. On the other hand, students with a kinesthetic learning style show good understanding, prepare appropriate plans, carry out steps systematically, and recheck the results according to Polya procedures, so that they get the correct answers and are confident in the results. This research provides insight into the influence of learning styles on mathematical problem solving abilities and the importance of paying attention to the re-examination step in the learning process.
