Abstract

The development of technology in this world is growing rapidly. Today, development of technology has penetrated and developed considerably, especially in the education sector such as the use of google sites, Geogebra, etc. which can be used as learning media, especially in the field of mathematics. However, this technology-based learning media only places students as passive elements in the learning process. The passive element in question is the lack of spatial reasoning ability of students in understanding learning materials, one of which is Space Geometry material in mathematics subjects. To create teaching and learning that is easy to understand in order to improve spatial abilities, it is necessary to have props that can visualize space buildings so that students can better describe the space buildings being studied. AR-based technology can be a solution to improve students' spatial reasoning because AR is an interactive media and has visualization capabilities. The application of technological aids like AR, if properly utilized, will be a great way to counter students' passivity. Learning mathematics using Augmented Reality technology innovation could simplify learners in understanding the material, especially in geometry material. Based on this, we developed teaching aids on three-dimensional building materials.

Abstract

This study aims to describe the mathematical representation abilities of eleventh-grade students in solving matrix problems. A qualitative approach with a case study design was employed. The research participants consisted of six students selected from a total of 29 students in Class XI MIPA 4 at SMAS Mujahidin Pontianak. Participants were chosen through purposive sampling based on three levels of mathematical ability (high, moderate, and low) with two students representing each category. The study analyzed students' representation abilities across three dimensions, namely visual, symbolic, and verbal. Data were collected through written tests and interviews. The data analysis process involved three stages: data condensation, data display, and conclusion drawing. The results revealed that students with high ability demonstrated comprehensive mastery of all three forms of representation. Students with moderate ability showed sufficient proficiency in visual and symbolic representation but had limitations in verbal representation. Meanwhile, students with low ability encountered difficulties in all three aspects. These findings suggest that teachers should design instructional strategies and tasks that promote students' abilities to make conjectures, interpret, justify, and connect mathematical ideas, thereby enhancing students' mathematical representation abilities.

Abstract

This study aims to analyze the types of difficulties encountered by students in solving linear equation problems in relation to their mathematical communication skills. A qualitative approach with a descriptive method was employed. The research subjects consisted of 30 eighth-grade students from a junior high school in Tasikmalaya, selected purposively. Research instruments included a written test to identify students’ difficulties in mathematical communication and a guided interview protocol to explore the underlying causes of these difficulties. Data were analyzed using thematic analysis and triangulation techniques to ensure validity and reliability. The findings revealed three primary categories of student difficulties: (1) difficulty in representing linear equations graphically due to limited understanding of coordinate systems and variable relationships; (2) difficulty in clearly articulating mathematical reasoning, indicating weak verbal communication skills; and (3) difficulty in formulating mathematical models from contextual problems, demonstrating a reliance on procedural strategies without conceptual understanding. The discussion highlights that these communication challenges stem from instruction that overemphasizes procedural outcomes and provides limited opportunities for students to engage in reflective mathematical discourse. The study implies the need for communicative, concept-based learning designs that integrate real-world contexts, emphasize multiple representations, and promote reflective practices. It is recommended that teachers incorporate collaborative learning strategies and interactive visual media to foster students’ mathematical communication skills, particularly in algebraic contexts.

Abstract

Mathematical modeling plays an essential role in mathematics learning, particularly in developing students analytical and problem-solving skills. Linear programming, as one of the core topics in optimization, often presents conceptual difficulties for students when linking abstract mathematical formulations to real-world problems. This study aims to analyze learning strategies for teaching linear programming through the implementation of mathematical modeling to improve students conceptual understanding and reasoning abilities. A descriptive qualitative approach was employed, focusing on literature review and classroom observations related to the used of mathematical models in teaching linear programming. The findings show that incorporating modeling steps-such as problem identification, variable formulation, and interpretation of result-helps students comprehend abstract mathematical ideas more effectively. Moreover, the integration of mathematical modeling encourages active learning and promotes students engagement in solving contextual problems. In conclusion, the use of mathematical modeling as a learning strategy provides a meaningful framework that enhances understanding, crirical thinking, and problem-solving skills in linear programming instruction.
