Abstract

This study aims to describe and analyze the mathematical reasoning abilities of high school students with the Realistic Mathematics Education (RME) approach in the material of sequences and series. The RME approach in this study was applied in the form of RME reasoning questions. This research uses a descriptive qualitative research method. The subjects in this study were 33 students of class IX-E SMA, then reduction was made by taking three students, one with high, medium, and low reasoning abilities. The data was collected using an instrument of mathematical reasoning ability test in the form of an essay consisting of 4 valid and reliable questions, and by using interviews to obtain data in the form of student responses directly by providing a series of questions posed by the researcher to the subject. Based on the results of the study, several conclusions were obtained that the three subjects had a fairly good understanding of using questions that were close to examples in everyday life. Students who have high reasoning ability are able to master the five indicators of mathematical reasoning ability. Students who have moderate reasoning ability are only able to master three indicators of mathematical reasoning ability. Students who have low reasoning ability, are able to master one hand of mathematical reasoning ability.

Abstract

This research aims to determine the impact of implementing differentiated learning and how it is implemented in class VII mathematics subjects at SMP Negeri 8 Medan. This type of research is qualitative research with student informants and subject teachers who have become Driving Teachers. The results of the research show that the implementation of differentiated learning has an impact on changes in students' behavior in learning, as can be seen from the results of observations that students are more active in learning activities and creative in carrying out tasks so that students' learning outcomes match the learning objectives. Meanwhile, the implementation of differentiated learning by teachers can respond to learning needs by paying attention to the preparation, implementation and assessment of differentiated learning. This research illustrates that the implementation of differentiated learning has an impact on good changes in student behavior and learning outcomes and the implementation of learning must be in accordance with the steps of differentiated learning.

Abstract

This research aims to analyze students' ability to understand mathematical concepts in flat-sided spatial figures in terms of learning styles in class VIII-8 UPT SMP Negeri 8 Medan. This research method uses qualitative methods. Data collection techniques from questionnaire results in the form of a Google form which contains aspects of learning styles accompanied by indicators that must be answered and observations of learning activities. The written test used in this research was in the form of description questions regarding material on the flat side of a cube. This research was conducted in class VIII-8 UPT SMP Negeri 8 Medan which also served as the research subject. Based on the research results, most students in class VIII-8 UPT SMP Negeri 8 Medan for the 2023/2024 academic year have a visual learning style with a total of 82.43%, an auditory learning style 60.9% and a kinesthetic learning style 46.5%. Students have a tendency towards one of the visual, auditory or kinesthetic learning styles. Of the 31 students, it was found that 19 students had a tendency towards a visual learning style, 10 students had a tendency towards an auditory learning style and 2 students had a tendency towards a kinesthetic learning style. So it can be concluded overall that each student with a different learning style has a different understanding of mathematical concepts.

Abstract

The increasingly rapid development of technology and information has enabled transformation in the fields of education and teaching. This is clearly seen in the current curriculum expectations, where one of the expected learning outcomes from elementary school to middle school is that students are expected to have computational thinking skills. For this reason, the aim of this research is to look at students' abilities related to their computational thinking abilities. in solving the problems given. The results of the answers given by students are then analyzed according to the four foundations of computational thinking. This research is descriptive research with a qualitative approach. This research was carried out in the Mathematics Education study program, Universitas Islam Sumatera Utara in the Number Theory course. The sample used was 12 students taking Number Theory courses. The instrument used is a description of 2 questions which are given during the learning process on mathematical induction material. The students' answer sheets were then analyzed to get a picture of students' computational thinking abilities based on the four foundations. The results of this research show that students' computational thinking abilities still need to be improved, such as decomposition abilities which are 41.67% and abstraction abilities which are 58.33%. Overall, students' computational thinking abilities are still in the sufficient ability category.

Abstract

This research aims to improve students' ability to understand mathematical concepts through the application of the Problem Based Learning learning model which is integrated with the Culturally Responsive Teaching (CRT) approach and the TaRL (Teaching at The Right Level) approach. This research is a classroom action research with the subject of students in class IX-7 UPT SMP Negeri 8 Medan for the 2024/2025 academic year, totaling 29 students. The research method used is PTK (Classroom Action Research) which in this case occurs in two cycles, with cycle I consisting of 1 meeting and cycle II consisting of 1 meeting. Each cycle is carried out with a focus on learning models and the ability to understand mathematical concepts. Based on the results obtained from the second cycle, there was an increase compared to the first cycle with the difference in the highest score in the first cycle being 9 students and in the second cycle being 16 students, the average score was 8 students while in the second cycle there were 10 students and The lowest score experienced a decrease, namely in cycle I there were 12 students while in cycle II there were 3 students. So the difference in the percentage of high scores in cycle I and cycle II is 27%. This happened by making improvement efforts by integrating the CRT approach and the TaRL approach which resulted in improvements in the observation aspect.
