Digital Teaching Materials Based on Attention Relevance Confidence Satisfaction Substance Pressure Material

Teaching materials that are commonly used during the science learning process are printed teaching materials, so digital teaching materials are developed based on attention relevance confidence satisfaction (ARCS) on substance pressure material. Alessi and Trolip development model used in this research has 3 stages which include planning, design and development. The alpha test stage, results of the development of digital teaching materials found that ARCS based digital teaching materials were declared valid with a score of 71.48%, the beta test stage, the practical ARCS-based digital teaching material results given by three students in the high, medium and low categories get an average score of 80% which is included in the practical category and ARCS-based digital teaching materials were effective in improving class VIII student learning outcomes after the pretest and posttest were carried out and the N-gain result was 0.61 in the medium category. so that ARCS-based digital teaching materials on substance pressure material are declared valid, practical and effective
