Development of Problem-Oriented Mathematics Learning Videos on Scale Material for the Fifth-Grade Elementary School Students

Abstract

This research was conducted based on an analysis of the needs and problems that occur in the learning process. The occurrence of the Covid-19 pandemic made learning less than optimal so that students had difficulty in understanding the teaching materials. To optimize mathematics learning, it is necessary to develop learning media according to the needs of students. This research aimed to produce problem-oriented mathematics learning videos on scale material for the fifth-grade students at Public Elementary School No. 2 Ketewel, and to find out its validity. The type of research is a development research using the ADDIE model (Analyze, Design, Development, Implementation, Evaluation). The subjects of this study were subject content experts, instructional design experts, instructional media experts, and three fifth-grade elementary school students. The data collection instrument used was a questionnaire. The research data were collected using the method of observation, interviews and questionnaires. Data were analyzed using quantitative descriptive analysis and qualitative descriptive analysis. The results of this study indicated the process of developing problem-oriented mathematics learning videos on scale material for the fifth-grade elementary school students through the analysis, design, development, and evaluation stages. The results of the validity test of the instructional videos by instructional design experts obtained a percentage score of 85.41% with good qualifications. The results of the validity test of the instructional videos by instructional media experts obtained a percentage score of 85% with good qualifications. The results of the validity test of the instructional videos by subject content experts obtained a percentage score of 87.5% with good qualifications. The results of the validity test of the instructional video by individual trial subjects obtained a percentage score of 95.66% with very good qualifications. Therefore, the problem-oriented mathematics learning on scale material for the fifth-grade elementary school students is valid for use in the learning process.
