Abstract

Mathematical literacy is an important ability that enables students to formulate, apply, and interpret mathematics in various real-life contexts. This study aims to analyze students' mathematical literacy skills on the material of Two-Variable Linear Equation Systems based on the gender of class VIII students of SMPN 2 Mataram. This study uses a descriptive qualitative approach. The research subjects consisted of 37 class VIII A students, then two male students and two female students were selected as research subjects based on test results. Data collection techniques were carried out through tests and interviews. Data analysis was carried out based on six indicators of mathematical literacy, namely communication, representation, mathematization, designing problem-solving strategies, use of operations and symbolic language, and reasoning and giving reasons. The results showed that both male and female students had good mathematical literacy skills, but there were differences in presenting answers. Male students tended to be stronger in oral explanations but less in written answers, while female students were more careful, systematic, and consistent in written solutions. This difference indicates that variation in ability is more evident in the accuracy and method of solution delivery. This research demonstrates the need to implement more inclusive and differentiated learning strategies.

Abstract

This study aims to develop an augmented reality learning media using an ethnomathematical approach on curved-sided geometric shapes that is valid, practical, and effective in improving students' critical thinking skills. This research and development (R&D) study adapted the 4D model. The sample consisted of 27 ninth-grade students from a junior high school in West Lombok. The augmented reality media was developed using Assemblr Edu in the form of interactive 3D worlds featuring Sasak cultural objects. During the development stage, two trials were conducted to obtain data on practicality and effectiveness. Research instruments included expert validation questionnaires (media and content), practicality questionnaires for teachers and students, and pretest and posttest questions on critical thinking skills. Data were analyzed using Aiken's V index for validity, percentages for practicality, and normalized gain (g) for effectiveness. The results showed that the developed augmented reality learning media was (1) valid, with an average Aiken's index score of 0.92; (2) practical, with an average practicality percentage of 92%; and (3) effective in improving students' critical thinking skills, with an average normalized gain (g) of 76%. Thus, the developed augmented reality learning media with an ethnomathematical approach is effective in enhancing students' critical thinking skills
