Abstract

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.

Abstract

The aim of the research is to summarize the experiences of grade 11 students at SMA Negeri 4 Palu based on Newman's theory. This type of research is descriptive, using a qualitative approach. The research subjects were two students selected from 35 class XI students. The findings of this research are as follows: (1) Not a single subject experienced errors in reading the lesson material, because at that time every subject was considered able to read the lesson material correctly. (2) Not a single subject made a mistake in understanding, as seen in the interview phase. All research subjects were able to provide understandable and questionable information regarding the subject. (3) Each research subject carries out transformation error correction. This transformation error is characterized by the failure of a subset that reduces the problem of the mathematical model. (4) Process skills errors were made by each research subject. This is explained by the subject's understanding of the steps taken in answering the question, but most of it is caused by the subject's errors occurring in the transformation step and the subject being unable to solve mathematical problems accurately. (5) an error in writing the final answer (encoding error) was made by each research subject; This is differentiated by the fact that there are subjects who do not determine the final results of their learning and there are also subjects who fail to determine the final results due to errors in the previous stage.

Abstract

Creative thinking in students is essential in the learning process. It can help students discover new ways to understand and solve problems. Through creative thinking, students do not merely focus on finding the correct answer but also learn to explore various possibilities and ideas. This study aims to obtain a description of students’ creative thinking profiles with logical-mathematical intelligence in solving mathematical problems, viewed from their learning styles. The focus is on how students with logical-mathematical intelligence utilize creative thinking in accordance with their individual learning styles. This research employs a qualitative approach. The research subjects are three 10th-grade high school students, each representing a combination of logical-mathematical intelligence with a different learning style: visual, auditory, and kinesthetic. Data were collected through students’ written responses and interviews. The results of the study show that at the stage of understanding the problem, subjects with logical-mathematical intelligence across all three learning styles demonstrated aspects of fluency and flexibility. At the planning stage, the visual and kinesthetic learners met all aspects of creative thinking, including fluency, flexibility, and novelty. In contrast, the auditory learner demonstrated only fluency and flexibility. At the stage of carrying out the plan, visual and kinesthetic learners again showed all aspects of creative thinking more completely than the auditory learner, who only demonstrated fluency and flexibility. However, in the reviewing stage, all subjects showed only fluency and flexibility, without the presence of novelty. These findings highlight the importance of considering students’ learning styles in developing creative thinking skills, particularly for those with logical-mathematical intelligence. An effective learning process must be designed with differentiation, taking into account students’ learning styles. With appropriate strategies, students can not only understand the material well but also fully develop their creative thinking potential at each stage of problem-solving.

Abstract

This study aims to explore students' commognitive processes in solving linear programming problems based on their learning styles. Conducted with three female students from Class XI MIPA 4 at SMAN 5 Palu, the study included one student each with visual, auditory, and kinesthetic learning styles. Data collection involved administering a learning style questionnaire and linear programming tasks (SBMPTN 2014 Code 663) that were linguistically validated to suit the students in Palu. Interviews were also conducted while the students worked on these tasks. Results indicate that the visual learner responded to problems in a detailed, repetitive, efficient, and accurate manner, demonstrating all four commognitive indicators. The main finding was the student's clear process in visualizing the problem. The auditory learner also responded well, demonstrating the four commognitive indicators but faced difficulties in the routine aspect, especially in transforming the problem into a narrative form, which is crucial for problem-solving. The kinesthetic learner showed clear, accurate responses and exhibited all four commognitive indicators, with a notable habit of using finger-pointing during explanations. However, limitations were observed in the narrative aspect, where the student relied more on physical experience than on logical, in-depth explanation.

Abstract

The development of Artificial Intelligence (AI) technology opens up significant opportunities for improving the quality of mathematics learning. However, many high school mathematics teachers are still unfamiliar with the use of AI, particularly the use of the Python programming language as a learning support medium. This community service activity aims to improve the knowledge, understanding, and skills of high school Mathematics MGMP teachers in utilizing Python-based AI technology in the learning process. The implementation method includes a preparatory stage in the form of coordination with partners, observation, and interviews to identify teacher needs, and an implementation stage consisting of two training sessions. The first training phase focused on providing conceptual material regarding AI applications in learning, while the second training phase included practical assistance in creating AI-based learning media using Python. The results of the activity showed an increase in teachers' understanding of AI concepts and practical skills in using Python to develop simple interactive quizzes in mathematics learning. Furthermore, participants demonstrated active and collaborative participation throughout the activity. Thus, this community service activity contributed to improving teachers' technological literacy and encouraging innovation in more interactive mathematics learning. It is recommended that similar activities be carried out continuously with a broader scope of material to optimize the use of AI in learning
