Abstract

The Vedic numeral system from India is one of the ancient mathematical heritages with significant historical and scientific value. This study aims to examine the Vedic numeral system from historical and scientific perspectives through a critical literature review. The research method used is a literature study that gathers and analyzes various academic sources regarding the origins, development, and relevance of the Vedic numeral system in modern mathematics. The findings indicate that this system has made significant contributions to the development of the concept of zero and the decimal system, which form the foundation of modern mathematics. Additionally, the principles of Vedic Mathematics have been proven to simplify various arithmetic operations, making it an efficient method for teaching mathematics. Despite its advantages, the application of the Vedic numeral system in education still faces challenges, particularly in academic documentation and adaptation into modern curricula. Therefore, further research is needed to evaluate its effectiveness in learning and its application in various scientific and technological fields.

Abstract

This study aims to improve the numeracy literacy abilities of students who are still relatively low. In addition, the use of Delightex Edu media, which had never been used in the learning process at SMP Negeri 1 Siantar, makes the developed media a new innovation in mathematics learning at the school, especially to enhance students' numeracy literacy. This research is a development study involving 27 students of class VII-1 at SMP Negeri 1 Siantar. The research instruments consist of expert validation questionnaires, student practicality questionnaires, learning implementation observation sheets, two numeracy literacy tests, and student response questionnaires that have been validated. The analysis results showed that 1) the media expert validation achieved an average of 90.66%, and the content expert validation reached an average of 89.43%. 2) The results of the analysis of the student practicality questionnaire towards the media reached a percentage of 86.77%, and the analysis of the observation sheets on the implementation of learning reached an average of 86.95%. 3) The results of the classical completeness analysis reached a percentage of 85.18% with the number of students achieving complete scores being 24 students, and the results of the student response questionnaire analysis reached a percentage of 94.08%. 4) The N-Gain score as an improvement in students' numeracy literacy obtained was 0.60, which falls into the medium category, with details of 15 students in the medium category, 9 students in the high category, 2 students in the low category, and 1 student did not experience improvement. Thus, this learning media is feasible, practical, and effective to use in mathematics learning in the classroom.
