Development of Digital Teaching Materials on Earthquake Themes to Improve STEM Literacy

Abstract

This study aims to produce digital teaching materials on the theme of Earthquakes that can improve student STEM literacy. The research method uses research and development with the ADDIE model which includes Analyze, Design, Develop, Implement and Evaluate. Data was collected using expert validation sheets, valid questions about STEM literacy, 25 questions, questionnaires for teachers and students, and understanding tests. The collected data is analyzed descriptively. Analysis of the content contained in STEM literacy in student handbooks so far shows teaching materials that have not been charged with STEM literacy (31%). The digital teaching material designed has been validated by material experts and media with yields of 97.5% and 87.50%. The assessment was also carried out by teachers with the acquisition of CVR for material and media by 0.88 and 0.87. The acquisition of student teaching material trials in one to one trial (81%), small group trials (85%) and field trials (86%), and the results of test students’ understanding of 54%. After being revised, teaching materials were implemented for 32 class VIII students. Before and after implementation, pretest and posttest were conducted with an average gain of 50.50 and 76.50, and N-gain averaged 49.34%. Based on this, it is concluded that digital teaching materials designed can improve STEM literacy in the medium category.
