Abstract

Purpose – This study aims to analyze students' ability to understand the concept of compositional functions based on indicators of understanding mathematical concepts. Understanding concepts is important in learning composition functions because students not only need to be able to do calculations, but also understand and apply concepts appropriately. Methodology – This study uses a qualitative approach with a qualitative descriptive research type. The research subjects consisted of six grade XI students at one of the Vocational High Schools (SMK) in Pekanbaru City in the even semester of the 2025/2026 school year. Subjects were selected using purposive sampling based on the results of the concept comprehension test. Data were collected through a description test consisting of two questions of composition function material. Data analysis is carried out based on two indicators of concept understanding, namely applying concepts algorithmically and presenting concepts in various mathematical representations. The percentage of achievement of each indicator is calculated based on the number of students who meet the indicators. Findings – The results of the study show that students' abilities are in the high category. The indicator applied concepts algorithmically reached a percentage of 83.33%, while the indicator presented concepts in various mathematical representations reached 100%. However, errors are still found in the application of composition procedures, especially in the process of function substitution. Novelty – This study provides an overview of the ability to understand the concept of composition function based on two indicators specifically in vocational school students. Significance – The results of the research can be an input for teachers in designing learning that emphasizes understanding of concepts, procedural accuracy, and the use of various mathematical representations.

Abstract

Purpose – Mathematical communication is a fundamental component of mathematics education that supports conceptual understanding, reasoning, and collaborative learning. Despite the rapid growth of related studies, the field remains fragmented, limiting a comprehensive understanding of its scientific development, intellectual structure, and emerging research directions. This study aimed to map the global research landscape of mathematical communication through bibliometric analysis. Methodology – A bibliometric analysis was conducted on 9,574 English-language journal articles indexed in Scopus. Following the PRISMA guidelines, the study employed VOSviewer to analyse publication trends, co-authorship networks, keyword co-occurrence, Total Link Strength (TLS), overlay visualization, and density visualization. Findings – Publication output has increased markedly since 2015, reflecting the growing importance of mathematical communication in mathematics education. Scientific production remains concentrated in a few countries, while collaboration networks are fragmented. The field is intellectually structured around mathematical communication, collaborative learning, self-regulated learning, cognitive engagement, and higher-order thinking skills. Recent research has shifted towards digital pedagogy and technology-enhanced communication, whereas technology-integrated communication, co-regulated learning, longitudinal studies, and cross-cultural research remain underexplored. Novelty – This study presents the first comprehensive bibliometric mapping that integrates scientific development, intellectual structure, thematic evolution, and research frontiers of mathematical communication research. Significance – The findings provide an evidence-based foundation for future research, instructional innovation, and international collaboration in mathematics education.
