Abstract

This research aims to describe the difficulties experienced by students in solving mathematics story problems on opportunity material. The type of research used is a descriptive method with a qualitative approach. The study involved 30 students in class XII IPS 2 SMA Negeri 2 in Pekanbaru. Data were collected using a combination of tests and interviews. The overall research procedure involved three stages, namely the planning stage, implementation stage, and conclusions. Data were analysed using descriptive statistics. The results of this study show that students’ experienced difficulties in solving mathematics story problems on opportunity material especially in understanding the problem (33,33%), carrying out transformations (36,66%), processing skills (38,88%), and difficulty in drawing conclusions (51,11%).

Abstract

This research aims to describe students’ mathematical communication skills in solving problems, especially matrix material in class XI 2 students at SMA Negeri 2 Tambang. The type of research used is a descriptive method with a qualitative approach. Data collection techniques were carried out using observation, tests, interviews and documentation methods. The test instrument used is 3 essay questions about students’ communication skills which have been validated. The subjects of this research were 28 students in class XI 2 SMA Negeri 2 Tambang. Then 4 students were selected as representatives of the research subjects based on the category of mathematical communication skills used. The results of this research show that students’ mathematical communication skills in solving questions on matrix material average 65,89 in the high category. Where there are 6 students (21,43%) in this very high category, there are 9 students (32,14%) in the high category, and there are no students in the low category.

Abstract

Learning styles refer to the methods students use in absorbing and processing information. This study aims to look at learning style factors in the achievement of mathematical computational thinking skills of mathematics education students in the Algebraic Structure course. This research method is a correlational method with a quantitative approach. The research subjects were all mathematics education students who took the Algebraic Structure course in the 2023/2024 academic year as many as 34 students. The data collection methods used include: (1) computational thinking test; (2) questionnaire; and (3) documentation. The research data were processed with the Product Moment correlation statistical test. The results obtained a positive correlation of 0.44 which indicates that there is a positive relationship between learning styles and computational thinking in the observed students. That is, overall, individuals who have a more effective or intensive learning style also tend to have better computational thinking ability.
