Mathematical Communication Skills of Junior High School Students in Solving Straight Line Equation Problems Based on Learning Interest

One of the skills that students should possess to compete in the 21st century is communication skills, including mathematical communication skills. In short, mathematical communication skill is an ability of students to convey their mathematical ideas. However, the facts show that the mathematical communication skills of junior high school students are still relatively low. This problem is closely related to learning interests. This study aims to analyze and describe the mathematical communication skills of junior high school students in solving straight-line equation problems based on learning interest. This study used a qualitative research method with a case study design. The research subjects were 33 grade VIII students from one of the junior high schools in Bandung, West Java, Indonesia. Data were collected using triangulation techniques from data on mathematical communication skills tests about straight line equations, learning interest questionnaires, and interviews. The research findings revealed that students with good and very good learning interests, mostly at level 3 mathematical communication skills (in general they can communicate ideas effectively but there are some small errors), students in the good enough learning interest category are at level 2 mathematical communication skills (can communicate some ideas with slightly ambiguous explanations), and students in poor learning interest are at level 3 mathematical communication skills (in general they can communicate ideas effectively but there are some minor errors). Keywords: mathematical communication,students, straight line equations, learning interest

Participation of Math Students in Online and Face-to-Face Hybrid Mathematics Instruction

Blended hybrid mathematics instruction offers the flexibility of online learning and the engagement of face-to-face interaction. However, research on student participation in these learning environments needs to be improved. This study investigated the dynamics of student participation, focusing on four key dimensions: conceptual understanding, mathematical communication, problem-solving, and critical thinking and analysis. A survey of 158 BS Mathematics students revealed that online learners tended to exhibit a higher level of conceptual understanding. At the same time, face-to-face interactions enhance problem-solving skills and stimulate more remarkable development of critical thinking and analytical abilities. Mathematical communication skills were somewhat constrained in both settings, with face-to-face students displaying slightly higher participation. These findings underscore the importance of considering the diverse dimensions of student participation when delivering online and hybrid mathematics courses. Educators should provide opportunities for students to hone and cultivate essential skills across online and face-to-face contexts, thus enriching their learning experience.

Developing Ethnomathematical-Based Learning Stages on Mathematical Communication Skills with Kastolan Error Analysis

Ethnomathematics-based learning has been effective for students' mathematical communication skills, but it can still be optimized by minimizing common student errors. Therefore, the objectives of this study are to analyze the shortcomings of students to solve mathematical communication problems in terms of students' skill categories; 2) analyze the learning process based on ethnomathematics with the help of the geoGebra application; 3) Develop learning steps based on ethnomathematics, analysing the shortcomings of the students. The study subjects were courageously selected, i.e. 36 students from the IX semester of the 2023/2024 academic year. Data were obtained through reported math skills, interest questionnaires, observation sheets, and dialogue sheets. Data analysis techniques begin with data analysis, testing students' mathematical communication skills, analyzing qualitative data, interpreting research results, and analyzing quantitative data. According to the analysis of the errors made by the students in solving mathematical communication problems, in terms of the categories of student ability, the students made more procedural errors in the categories of medium and low skills. At the same time, students in the high-ability category tend not to make significant mistakes. The results of the triangulation found two stages of learning necessary to minimize student errors, i.e., the exercise stage and the research stage. The stages of ethnothematic learning are exploration, mapping, explanation, exercise, research, and reflection. The effectiveness of the learning model developed in the mathematical communicative skills of the students will be analyzed for future research.

The conclusion is probing-prompting learning with performance assessment can be used to improve students' mathematical communication skills and based on students’ mathematical resilience, students also have different levels of mathematical communication skills.

Improving Mathematical Communication Skills Through the Geogebra-helped PBL and Direct Instruction Reviewed from the Level of Learning Independence

This research aims to analyze the improvement of junior high school students' mathematical communication skills through Problem Based Learning (PBL) assisted by Geogebra and Direct Instruction assisted by Geogebra. The research also considers the level of student learning independence. The research method used was a quasi-experiment with a pretest-posttest design and a control group, involving two treatment groups. groups that underwent the PBL approach with the help of Geogebra and Direct Instruction with the help of Geogebra. Students in this study were divided based on their level of learning independence. Data was collected through an initial test (pretest), implementation of learning, and a final test (posttest). Data analysis involved a comparison between the increase in students' mathematical communication skills before and after treatment in the two treatment groups, as well as the influence of the level of learning independence on increasing mathematical communication skills. The research results show that both learning approaches contribute to improving students' mathematical communication skills. However, the group that took part in PBL assisted by Geogebra showed more significant improvement compared to the Direct Instruction group assisted by Geogebra. In addition, it was identified that the level of student learning independence influences the results of improving mathematical communication skills, where students with a high level of learning independence tend to benefit more from PBL assisted by Geogebra. In order to improve students' mathematical communication skills in learning spatial material, it is recommended that educators consider using Geogebra-assisted PBL and pay attention to students' level of learning independence in designing effective learning strategies.
