Abstract

This study aims to develop a contextual mathematical literacy instrument based on local wisdom that is valid, reliable, and practical for junior high school students. The development of this instrument was motivated by the limited availability of assessment tools capable of measuring students’ mathematical literacy comprehensively and in alignment with their cultural contexts. The research employed the ADDIE development model, consisting of five stages: analysis, design, development, implementation, and evaluation. The study involved 30 students from a junior high school in Tangerang Regency. Data were collected through written tests, expert validation sheets, classroom observations, and practicality questionnaires. The results of expert validation showed an average score of 4.65, indicating that the instrument is highly valid. Field trials revealed a reliability coefficient of α = 0.89, suggesting high internal consistency. Furthermore, the practicality and acceptability levels reached 88.7% and 90.3%, respectively, both categorized as very good. These findings indicate that the developed contextual mathematical literacy instrument based on local wisdom is feasible for use as an authentic assessment tool to evaluate students’ mathematical literacy skills in a meaningful and culturally relevant manner.

Abstract

Technological developments demand adaptation in the world of education, particularly in the integration of technology into mathematics learning. Prospective student teachers need to possess the competencies to create innovative learning media that are not only content-accurate but also visually and technologically engaging. This study aims to describe the implementation of the Project-Based Learning (PjBL) model with STEAM (Science, Technology, Engineering, Art, and Mathematics) content in producing Android-based mathematics learning media. The method used was descriptive qualitative through triangulation of observation data, discussions, and analysis of the output product. The results showed that PjBL facilitated students in practicing the engineering cycle of media creation. However, obstacles were encountered in the Technology and Mathematics elements, where students experienced difficulty transforming textbook content into the system logic of an Android application. Furthermore, technical barriers to mastery of tools (Technology) such as iSpring Suite were a major challenge. Nevertheless, this approach successfully encouraged students to integrate art elements into interface design and mathematical logic within a single, integrated product. It was concluded that the implementation of PjBL with a STEAM nuance effectively helped lecturers and students produce usable digital media products.

Abstract

This study aims to develop and evaluate an offline digital learning media based on GeoGebra, designed specifically for technology-constrained school settings, to enhance students' spatial ability in learning flat-sided geometric shapes. Employing a Design-Based Research approach, the study involved limited trials with 18 students and one teacher, followed by implementation in another school with 40 students divided into experimental and control groups. Quantitative data were analyzed using ANCOVA, revealing a significant difference (, , ). Qualitative analysis indicated increased student engagement and spatial understanding. Featuring 3D visualization and interactive simulations in an HTML5 offline format, the offline media offers flexible and accessible learning for under-resourced environments. Theoretically, this research extends the media of Dual Coding Theory and Design-Based Research (DBR) within resource-limited educational contexts by demonstrating how offline visual-spatial media can effectively bridge abstract geometric concepts. Practically, it provides a scalable, concrete solution for educators in technology-constrained schools to implement interactive, GeoGebra-based mathematical learning without requiring internet access or high-end infrastructure.
