Development of Interactive Learning Video on Linear Program

Abstract

The current condition of the Covid-19 Pandemic requires students to study independently. One of the learning media that can help students solve problems is video-assisted learning. The development of learning video is beneficial to assist teachers in teaching and learning activities. In addition to increasing students' learning interest, learning videos can also help students enter deeper mathematical understanding. The mathematical material is abstract that usually makes students think that mathematics is a difficult lesson. Linear Program at senior high school level is applied mathematics with mathematical models compiled from multiple equations or linear equivalencies to determine the maximum or minimum value. This study aims to develop learning media for linear program mathematics content. This research uses research and development (R&D) method with the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). The sample of the research is one of the high schools in West Java, Indonesia. The validation results of media experts and material experts show learning video is feasible to be implemented to students. The school implementation also established a learning video that using the problem-solving steps is constructive for students to create the mindset and understand the basic concepts in a linear program. This study's results also contribute to the achievement of the objectives of learning mathematics for the better based on the use of video-based learning in improving the mathematical abilities of high school students.
