This study aims to describe the problem-solving profile of grade IX students of SMP Negeri 2 Palu in solving profit and loss material problems based on their self-efficacy levels. The research approach used is descriptive qualitative, with research subjects consisting of two students, each with a high and low level of self-efficacy. Data were collected through self-efficacy questionnaires, written tests, and interviews, which were analyzed using the Miles and Huberman model. The results showed that students with high levels of self-efficacy were able to complete each stage of problem solving based on Polya's steps well, starting from understanding the problem, planning problem solving, implementing the plan, to re-checking the results. High self-efficacy students showed confidence and accuracy in identifying information, designing solutions, and performing calculations. In contrast, students with low self-efficacy were only able to understand part of the information, often made mistakes in calculations, and did not re-check the answers because they lacked confidence. The self-efficacy factor has been shown to influence students' ability to solve mathematical problems.

This study aims to describe students’ mathematical communication skills in solving problems related to angle relationships, taking into account gender differences among students of SMP Negeri 1 Sindue Tobata. This research employed a qualitative approach with two eighth-grade students as subjects, consisting of one male and one female student, both identified as high-ability learners. Data were collected through tests and interviews. The results revealed that the male student demonstrated mathematical communication skills in understanding mathematical ideas both orally and in writing, using mathematical terms and notations, interpreting mathematical ideas through graphs and symbols, and evaluating ideas orally, although his written evaluations were still lacking. In contrast, the female student exhibited better skills in evaluating mathematical ideas both orally and in writing. These findings provide insights into the differences in mathematical communication skills between high-ability male and female students within the context of mathematics learning.

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.

The problem in this research is that one of the mathematical materials that is considered difficult by students is the material on flat-sided solid shapes of cubes and cuboids. One of the causes of the lowstudent learning outcomes due to lack of student interest in mathematics lessons, students are not active in learning, students only tend to memorize not understanding the concept and lack of interaction between students and teachers so that students often make mistakes in solving problems, mistakes shown by students in mathematics learning are not only caused by this subject has an abstract nature and requires a serious learning atmosphere, but also influenced by factors from the students themselves and their environment. This type of research is Classroom Action Research (CAR). Data collection techniques in this study used observation, interviews and field notes. This study consists of two stages, namely the pre-action stage and the implementation of the action. The results of this study indicate that the application of a problem-based learning model using differentiated learning can improve student learning outcomes in the material on the volume and surface area of cubes and cuboids through the following stages: (1) orienting students to the problem, the teacher presents the material, (2) organizing students to learn, the teacher forms study groups, (3) guiding individual and group investigations, the teacher guides students in collecting information, (4) developing and presenting the results of their work, the teacher asks several groups to present the results of their discussions to their friends in front of the class, and (5) analyzing and evaluating the problem-solving process, the teacher and students together conclude the material that has been studied.
