Abstract

This study aims to analyze the mathematical representation ability of SMA Negeri 1 Sungai Kakap students on Pythagorean theory material using visual, symbolic, and verbal strategies. The method used was quantitative descriptive with the research subjects of 36 students in class X. The collection method included questionnaires, reports, and documentation. The instruments used for data collection in this study are mathematical representation test questions and interviews. Data analysis techniques are carried out with quantitative data analysis techniques and descriptive analysis techniques. Based on the test results, it shows that students' mathematical representation skills need to be improved, with an achievement rate of 43% with a medium category. Students' visual representation ability was only 36%, while verbal and symbolic representation was much higher, at 42% and 50%, respectively. In general, students can answer the questions correctly, but there are errors in interpreting and translating the representation between visual, symbolic, and verbal. These findings point to the need for improved understanding and translation between different forms of mathematical representation to improve understanding of the concept of the Pythagorean theorem.

Abstract

Prospective teachers must possess strong knowledge of technology, pedagogy, and mathematical content to ensure optimal learning outcomes. Therefore, mathematics teacher candidates are equipped with knowledge of technology, pedagogy, and content through various courses. However, the effectiveness of these courses in enhancing Technological, Pedagogical, and Content Knowledge (TPACK) must be regularly assessed as part of the evaluation process for teacher education programs. This study aims to describe the TPACK achievement of second-year mathematics teacher candidates. The research is a survey study involving 18 second-year mathematics education students at a university in Jambi, Indonesia. A TPACK questionnaire comprising 7 components with a total of 35 items was used. Interviews with program coordinators were conducted to enrich the data on curriculum content designed to support students’ TPACK development. The results indicate that the students’ mastery of TPACK is not yet optimal. The university needs to further optimize TPACK mastery through courses or extracurricular activities during the remaining period of study.

Abstract

The Basic Calculus course is one of the compulsory courses that must be mastered by prospective mathematics teachers. This study aims to analyze the errors in the topic of Continuity in terms of prospective mathematics teachers’ ability to (1) interpret function graphs, (2) draw functions, and (3) utilize relevant concepts to construct written solutions. This is a descriptive study involving 27 second-semester of prospective mathematics teachers enrolled in Basic Calculus course as the subject of the study. Data were collected through written tests to all subjects, and interviews to selected subjects. The analysis of students' written answers revealed five types of errors: (1) errors in reading function graphs, (2) errors in sketching function graphs, (3) errors in determining the limit value of functions, (4) errors in understanding the concept of division by zero, and (5) errors in using the concept of Continuity. The findings of this study indicate that 66.67% of prospective mathematics teachers continue to demonstrate a limited proficiency in reading function graphs, 59.26% of students exhibit a lack of competence in function sketching, and 25.93% of students have a low level of ability in utilizing concepts to construct written solutions.

Abstract

This research aims to examine the achievement of junior high school students' mathematical critical thinking abilities, both overall and based on students' initial ability categories (low, medium, high). Apart from that, this research wants to compare two learning approaches, namely problem based learning and ordinary learning, towards this achievement. The method used in this research was quasi-experimental by selecting research subjects, namely Class VIII Middle School students consisting of 32 students with low, medium and high KAM classifications. The data collection used is based on test results based on indicators of students' critical mathematical thinking abilities. The results of the research prove that the achievement of critical mathematical thinking abilities of students who learn using the problem-based learning model and the achievements of students who study normally viewed as a whole and based on initial abilities (low, medium, high) have significant differences.

Abstract

The aim of this research is to examine the influence of the Realistic Mathematics Education (RME) approach in improving students' mathematical communication ability. In this research, a quasi-experiment was used, with the research using the non-equivalent pretest-posttest control group design. Eighth grade students at PGRI 1 Cimahi Middle School were the subjects of the research. To measure mathematical communication ability, data was obtained from four test questions that had been tested previously. Next, the data obtained will be analyzed and processed using analysis of 2 dependent samples using a normality test first, followed by a paired t-test. Mathematical communication ability improve much better for students who use the RME Approach compared to students who use the regular learning approach.

Abstract

This research aims to see the results of increasing mathematical problem solving abilities using the problem based learning model. The method used in this research is a quantitative method with a quasi-experimental type of research and uses a Nonequivalent Control Group design. The sample in this study was 20 students from each class. Class VIII B is the experimental class and class VIII D is the control class. The data collection technique in this research uses written test instruments, namely pretest and posttest. Data management in this research began with a test of students' mathematical problem solving abilities, namely using a pretest and posttest. After that, the data from the pretest and posttest results were processed by carrying out the t-test and Ngain test. The results of this research show that the problem based learning model can improve students' mathematical problem solving abilities. The conclusion of the research shows that the problem based learning model is better than ordinary learning for improving students' mathematical problem solving abilities.

Abstract

This approach focuses on students' thinking procedures. This study aims to describe the obstacles of students in innovative learning using Kahoot! in solving mathematics problems according to Robert Gagne's theory. Information processing theory explains how information is received, processed, and stored in memory, where difficulties can arise at each stage, such as limited short-term memory capacity and problems in encoding information into long-term memory. This research method uses a qualitative descriptive approach, with data collection through observation, interviews, and group discussions. The subjects in this study were all OFF G mathematics students in semester 1 at Malang State University in the 2024/2025 academic year, totaling 30 students. The data obtained in this study were written tests in the form of questions on the material of composition functions and inverse functions and interview guidelines. The research results indicate that: (1) students experience obstacles related to understanding each procedure for solving mathematics problems, concepts, procedures, or principles for working on mathematics problems, and (2) the trigger for students' limitations in learning mathematics is the lack of motivation from students to access information that they do not understand.

Abstract

The purpose of this study was to improve students mathematical literacy skills in statistics by appliying the Contextual Teaching and Learning (CTL) approach. Students of SMP Negeri 2 Padalarang became the population in this study. Thirty students of class VIII-A served as the experimental group and thirty students of class VIII-I served as the control group. This study used a non-equivalent control group design with quasi-experimental research methodology. This study included pretest, action, and posttest. This research tool used a written test to collect information about the improvement of students’ mathematical literacy skills. Data analysis was carried out by conducting normality test, homogeneity test and mean test in order to obtain conclusions. The findings of this study show that the improvement of mathematical literacy skills of students whose learning uses the Contextual Teaching and Learning (CTL) approach is better the those who use ordinary learning.
