Abstract

This study aims to analyze students’ mathematical connection skills in solving contextual problems involving flat-sided three-dimensional shapes, based on the limited existing literature regarding students’ thought processes when connecting concepts to complex problems. The research approach adopts a qualitative case study method. The research subjects consisted of 34 ninth-grade students in class IX-H at a junior high school in Jakarta, selected to describe variations in mathematical connection skills. The instrument used was a validated mathematical connection skills test. Data were analyzed in depth through the students’ responses. The results of the study indicate significant variations in connection abilities; the majority of students were able to complete general procedures but faced difficulties with contextual problems requiring the integration of multiple concepts. A disruption in the flow of thinking was observed when students were presented with contextual problem narratives involving complex thinking stages. These findings indicate the importance of strengthening abstraction skills and problem-modeling strategies in the learning process to help students connect various mathematical concepts when solving real-world problems.

Abstract

Mathematical problem-solving ability is not only related to the mastery of concepts and procedures but is also influenced by affective factors such as self-efficacy. This study aims to analyze students’ mathematical problem-solving abilities in the topic of Three-Variable Linear Equation System based on Polya’s procedures in terms of self-efficacy. This type of research is descriptive research with a qualitative approach. The study was conducted at a public senior high school in Bogor Regency involving 30 eleventh-grade students, with three students selected as the main subjects based on high, moderate, and low self-efficacy categories. Data were collected through a self-efficacy questionnaire and a mathematical problem-solving ability test based on Polya’s four-step procedures. The findings revealed that students with high self-efficacy were able to carry out all problem-solving procedures systematically and consistently. Students with moderate self-efficacy demonstrated fairly good ability but were not yet consistent, particularly lacking thoroughness in understanding the problem and still making errors at the evaluation stage. Meanwhile, students with low self-efficacy tended to experience difficulties in solving problems, characterized by a lack of problem understanding, inaccuracies in constructing mathematical models, and failure to evaluate the final results. These findings confirm that the higher a student’s self-efficacy, the better their problem-solving ability.

Abstract

The ability to represent mathematical concepts is one of the crucial skills. However, this skill has not developed well. This study aims to explain how ninth-grade junior high school students can demonstrate mathematical representation related to verbal, pictorial, and symbolic elements. The descriptive quantitative method is used in this study, which involves the analysis of descriptive statistical data. There are 33 junior high school students in Karawang Regency who are the subjects of the study. This study uses a series of tests consisting of six questions based on the metrics of mathematical representation ability. The collection of student ability categories, average, and standard deviation were calculated for data analysis. As shown by the research results, students do not have ideal mathematical representation skills. While most students have moderate scores, their average is still below standard. Image representation reached the highest level, while verbal representation reached the lowest level. These findings show that students struggle to convey mathematical concepts and relate various representations when solving statistical problems. Therefore, a more structured learning method is needed to strengthen students' abilities in mathematical representation.

Abstract

Statistics learning requires contextual teaching materials that can help students represent data visually, symbolically, and verbally. However, statistics worksheets used in learning are often procedural and less connected to students’ cultural contexts. This study aims to determine the validity of Seren Taun ethnomathematics-based statistics worksheets designed to facilitate students’ mathematical representation skills. This research employed research and development (RD) using the ADDIE development model, limited to the analysis, design, and development stages. Preliminary data were collected through literature study and interviews with a mathematics teacher and grade XI students at SMAN 3 Cikarang Utara. Product validation was conducted by material experts, cultural experts, and media experts using validation questionnaires based on a four-point Likert scale. The data were analyzed using descriptive percentage analysis. The results showed that the worksheet obtained validity scores of 96% from material experts, 86% from cultural experts, and 97% from media experts, with an average score of 93% in the very valid category. Therefore, the worksheet is feasible as a contextual learning material to facilitate students’ visual, symbolic, and verbal mathematical representation skills in statistics learning.

Abstract

Students need to develop sufficient mathematical literacy. In reality, however, not all students demonstrate good mathematical literacy. The project-based learning (PjBL) model is a recommended teaching model, then STEM is a broad approach. This echo produces a STEM-integrated project learning model. Based on this description, researchers designed and developed Local Instructional Theory (LIT) in the form of mathematics learning with a STEM-integrated project learning model on the topic of lines and angles. This study uses a design research method, which includes three research stages: preliminary, teaching experiment, retrospective analysis. The research subjects were students taking Geometry courses. Data collection techniques used were interviews, documentation, field notes, and written tests that were collected and analyzed to improve HLT. This study was designed in three activities: creating a Joglo house project with maximum STEM-based enlightenment, identifying the concept of lines and angles and measuring angle sizes, then categorizing the types of angles and understanding the relationships between angles. From the results of all the activities that have been carried out, the learning trajectory provides students with activities that are enthusiastic in learning, creative in creating, active in discussions, and group learning to complete an assigned project. The use of LIT produces a design that has a strong theoretical basis because each learning syntax is compiled based on a synthesis of various theories and empirical research results, then validated through research and development stages.
