Abstract

The inclusion of ethnomathematical perspectives into the mathematics education of indigenous student is often described as being beneficial. Drawing on weaving activities from West Amarasi society in Timor Island, Indonesia, this paper examines the results from the exploration of mathematical concepts that exist and are practiced in this society. This is a descriptive exploratory with ethnographic qualitative approach research. Data were collected in March 2022 through observations, interviews, and documentation. Some indigenous people from Merbaun Village, West Timor, in East Nusa Tenggara Province, Indonesia, were participants in this research. The results showed that there were several ethnomathematics characteristics in the weaving activities of the West Amarasi society: counting, locating, measuring, designing, explaining, the use of implication logic, and estimating. It was also found mathematics concepts and ways of thinking such as the concept of multiplication as repeated addition, parallel of straight lines, geometric shapes, reflection, rotation, sizes and units, and logical implication. This finding can be used as a source of mathematics learning by teachers, researchers or mathematics education practitioners not only those local in West Amarasi but also in other similar places around the world.

Abstract

This research aims to create an Android-based learning application assisted by Articulate Storyline 3 software for class VIII students of SMP Negeri 13 Kupang that is valid, practical, and effective. The method used is Research and Development (R&D) with the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) model. Data collection techniques and instruments include interviews, questionnaires, and tests. The data analysis technique uses qualitative and quantitative descriptive analysis techniques. This research produces an Android-based application product named "Relations and Functions" and has met the criteria for validity, practicality, and effectiveness. For media validity, the average assessment by 3 material experts was 4.37, and the average assessment by 3 media experts was 4.38, so it has the "valid" category. For the practicality of the media in small-scale trials, the student response was 4.72, and the effectiveness of the media through the percentage of learning completion was 100%. Meanwhile, in the large-scale trial, the subject teacher's assessment response was 4.5 and the student response was 4.63, so it was in the "practical" category. For media effectiveness, the learning completion percentage was 83.33% and was categorized as "very effective". Thus, the learning application developed is valid, practical, effective, and suitable for use in learning activities.
