Abstract

The purpose of this study is to study literature related to differences in mathematical communication skills of high school students based on gender. The study uses the method of Systematic Literature Review (SLR) which is carried out through the process of identification, evaluation, and interpretation of all available research evidence with the object of the research is student mathematics communication skills and Gender. Design used is to summarize, review, and analyze 9 articles that are highly relevant to the subject of the study. The article used is an article in a journal accredited by Sinta. The results of this Systematic Literatur Review show that there is a difference in the ability to communicate mathematically between male and female students. Differences in mathematical communication skills between male and female students can be caused by a variety of factors, such as biological, social, and cultural factors. The way students process and understand mathematics can be influenced by biological factors, like differences in brain structures.

Abstract

This study aims to identify and analyze trends in commognitive research in mathematics education, focusing on four main components: word use, mediators, rules, and narratives. Additionally, this study seeks to explore how commognitive theory is applied in mathematics education research and to identify research gaps that can be further developed. The method used in this study is a Systematic Literature Review (SLR), with article searches conducted through the Google Scholar, SINTA, and Scopus databases within the 2015–2025 timeframe. Articles were selected based on strict inclusion and exclusion criteria, resulting in the final analysis of five relevant articles. Each article was classified based on research methods, key findings, and contributions to commognitive theory in mathematics education. The findings indicate that visual mediators and routines are the most frequently studied commognitive components, particularly in the context of technology use and touchscreen interaction in mathematics learning. Additionally, commognitive conflicts were commonly observed in the transition from school to university, particularly in students' understanding of mathematical terminology (word use) and the application of mathematical communication rules (rules). The primary finding of this study reveals that students with higher mathematical understanding tend to construct more argumentative mathematical narratives, while students with lower comprehension tend to rely on mechanical procedures without fully grasping the underlying concepts. For future research, further exploration of word use and narratives is recommended, particularly in the context of elementary and secondary school education.

Abstract

The purpose of this study was to examine the comparison of the quality of learning mathematics through the NHT and STAD models. This type of research is a quasi-experimental. The population in this study were all students of class VII SMP SMP Putri Yatama Mandiri in the 2021/2022 academic year and the samples in this study were taken by Saturated Sampling, namely class VIIA which was taught through the NHT model with a total of 25 students and class VIIB which was taught through the STAD model with a total of 25 students. The research design was a pretest-posttest control group design, which involved two classes that were given a pretest and a posttest. Data collection techniques are observation sheets of the implementation of learning and student activities, learning achievement tests, student response questionnaires. The results showed: 1) the average pretest score of students through the NHT model was 29.44 (very low) with a standard deviation of 6.01, 100% did not achieve individual mastery, meaning that classical mastery was not achieved, 2) the average score the average posttest of students through the NHT model is 85.20 (high) with a standard deviation of 5.35, 100% of students achieve individual mastery, meaning that classical mastery is achieved, 3) the average score of students' pretest through the STAD model is 38.08 (very low) with a standard deviation of 7.49, 100% obtained did not achieve individual completeness, meaning that classical mastery was not achieved, 4) the average posttest score of students through the STAD model was 81.6 (medium) with a standard deviation of 6.14, it was found that 23 students or 92% achieved individual mastery, meaning that classical mastery was achieved, 5) the average percentage of student response questionnaires that answered yes on NHT was 94.5% and on STAD 97%, meaning that 75% of students had fulfilled answer YES, and 6) the average gain is 0.79 on NHT and 0.70 on STAD. Thus the quality of learning mathematics through the application of the NHT model is not the same as learning mathematics through the application of the STAD model in class VII students of SMP Putri Yatama Mandiri Islamic Boarding School.

Abstract

This study aims to analyze the relationship between commognitive theory and students’ mathematical communication skills at the secondary education level, specifically in junior and senior high schools. This review is motivated by the importance of understanding students' thinking processes in expressing mathematical ideas verbally, visually, symbolically, and procedurally. Commognitive theory, which comprises four main components word use, visual mediators, narratives, and routines provides a conceptual framework for examining the dynamics of students’ mathematical discourse. The method employed is a Systematic Literature Review (SLR) following the PRISMA protocol. A total of 26 articles were analyzed, sourced from the Scopus and Google Scholar databases, with inclusion criteria covering publications from 2013 to 2024 relevant to the topic and the context of secondary school students. The findings were categorized into three major themes: (1) the application of commognitive theory in mathematics instruction at the secondary level; (2) indicators of students’ mathematical communication in written, oral, and visual forms; and (3) the interrelation between commognitive components and dimensions of mathematical communication. The review reveals that students exhibit varying tendencies in activating commognitive components depending on the type of task and the mode of problem presentation. Nevertheless, the explicit integration of commognitive theory and mathematical communication indicators has not yet been thoroughly explored. The implications of this review highlight the urgency of developing discourse-based assessment instruments, as well as designing challenging tasks that foster student engagement across all aspects of mathematical thinking and communication.

Abstract

Mathematics anxiety is one of the major barriers to students’ achievement and positive attitudes toward learning mathematics. Conversely, a growth mindset is considered a protective factor that fosters learning resilience. This study aims to explore the narratives of students with high levels of mathematics anxiety in relation to their growth mindset. A qualitative narrative approach was employed with three 11th-grade high school students in Malang Regency, Indonesia, selected purposively based on their scores on the Math Anxiety Questionnaire (MAQ). Data were collected through semi-structured interviews, written reflections, and field notes, and analyzed using thematic narrative analysis. The findings reveal five major themes: (1) initial negative perceptions of mathematics, (2) emotional responses to failure such as nervousness, frustration, or shame, (3) efforts to recover through diverse coping strategies, (4) social support from teachers, peers, and families that influences resilience, and (5) indications of growth mindset reflected in the belief that effort is more important than innate talent and mistakes are part of the learning process. These results highlight that although high mathematics anxiety poses challenges, a growth mindset can serve as a protective factor in building students’ learning resilience. This study contributes to the literature on the intersection between mathematics anxiety and growth mindset and provides practical implications for teachers to create a classroom climate that fosters positive mindset development.
