Abstract

The main problem in this study is students' ability to think mathematically in solving mathematical problems in learning social arithmetic in their class through minimum guidance-based learning (PBL and DL). This research uses a mixed method to look at the description of students' mathematical thinking abilities and the tendency of these abilities based on students' self-efficacy levels. The results showed that the increase in students' mathematical thinking skills at each level of low self-efficacy based on n-gain calculations. In addition, there is no significant difference in the scores for improving students' mathematical thinking skills based on the learning model and the level of self-efficacy. There is no significant interaction between the Learning Model and the Level of Self-efficacy in determining the increase in the average score of students' mathematical thinking abilities. Other findings show that students with low self-efficacy tend to have limitations in the ability to think mathematically in the process of conjecture and convincing. On the other hand, students with moderate and high self-efficacy have more complete mathematical thinking abilities, including specialization, generalization, conjecture, and convincing. However, in the process of conjecture and convincing, two sub-processes are found, namely knowledge modification using factual knowledge, contextual tools, or substantive thinking, as well as the process of selecting relevant information in solving problems. Therefore, the two groups are divided into four groups based on the way students use conjecture and convincing mathematical thinking abilities, namely: (1) students use specialization mathematical thinking skills based on the knowledge learned from the teacher, (2) students use specialization mathematical thinking abilities based on knowledge acquired in everyday life, (3) students use convincing mathematical thinking abilities by examining the formula used or based on knowledge learned from the teacher, and (4) students use convincing mathematical thinking abilities based on the knowledge obtained in everyday life (factual knowledge).

Abstract

The solution to numerical integration problems generally can be achieved using mesh methods. However, mesh methods, commonly known as trapezoidal, rectangular, and midpoint, only apply to Cartesian coordinates. Therefore, this research develops a mesh method that can be used for numerical integration in polar coordinates, specifically using Triangle shapes. This study also analyzes the errors from the results of the Triangle mesh method and provides examples and visualizations of applying the Triangle mesh method to solve numerical integration problems. The steps of this research are as follows: first, determining the form of the integral in the problem of numerical integration in polar coordinates. Then, the area bounded by the curve is divided into several parts, each approximated by a triangle. Next, a numerical integration formula of the triangle mesh method is created by summing the areas of each triangle. After that, the resulting error of the triangle mesh method is analyzed using the Taylor series. Finally, proving that the results of the triangle mesh method approximate the area bounded by the curve in polar coordinates. From this research, the numerical integration formula for the Triangle mesh method is obtained, the error formula with a second-order approximation degree, and based on the proof of the numerical integration formula for the Triangle mesh method, it is concluded that as the number of triangles approaches infinity, the results of the Triangle mesh method will converge to the exact area bounded by the curve.

Abstract

One of the most important things that students must learn in mathematics is conceptual understanding skills. However, in reality, students' conceptual understanding skills is often still low. The aims of this study is to test the difference in conceptual understanding between students who use the Geogebra-based Learning Management System (LMS) Canvas and those who do not use the media. This study uses a quasi-experimental quantitative type with a pretest and posttest non-equivalent control group design. The research subjects consisted of students in grade XI MIPA 1 and MIPA 2 at one of the high schools in Boyolali, each of which amounted to 36 students. The validated mathematical conceptual understanding skill test is applied as a research instrument. Descriptive and inferential statistics are used in data analysis. The results showed that there was a significant difference in student's conceptual understanding skills in the experimental and control classes.  In addition, the results showed that compared to the control group, the experimental group had superior conceptual understanding skills. This is shown by the median and mean rank of students' posttest scores in experimental class (median = 80; mean rank = 51.25), higher than in control class (median = 46; mean rank = 21.75).

Abstract

Divergent thinking is characterized by thinking in all directions, always trying various solutions to solve problems, so several ideas or solutions emerge. Divergent thinking in this study is based on four aspects; fluency, flexibility, originality, and elaboration. This study used a descriptive qualitative approach with two subjects of class VIII students of SMP Negeri 1 Ploso Jombang in the academic year 2024/2025, male student are (BAE) and female student are (AN). Data collection technique for this research carried out by giving the DTT written test and interviews. Data were collected through the Divergent Thinking Test (DTT) and semi-structured interviews had been validated by experts. This research is a qualitative descriptive research. The selection of subjects in this study considering by gender. For data collection technique in this study using a DTT written test and interview. Data analysis method carried out with three stages of analysis. The results showed that the female subject (AN) excelled in all indicators of divergent thinking AN produced three different problem-solving strategies, such as calculating the area of the outer square minus the shaded area, dividing the square into two rectangles, and dividing the square into smaller elements. AN provided a detailed explanation in developing the solution. Subject BAE produced two strategies, which tended to be simpler and conventional, without much variation. In the aspect of problem solving based on Polya's steps (understanding the problem, planning the solution, executing the solution, and re-examining), both subjects could follow the steps. However, AN showed more depth in planning and re-examining, by exploring various alternative strategies and BAE was simpler in solving the problem and thought more efficiently.
