Improving Student Learning Outcomes in Online Learning by Using Electronic Teaching Materials

Abstract

The availability of teaching materials that can be used in distance or face-to-face learning causes teachers to rely only on one book in learning. It causes learning to be monotonous, and students have no interest in learning. This study aims to develop illustrated electronic teaching materials for fifth-grade elementary school classroom building materials that have been declared valid and feasible, and have effectiveness in the learning process. This research is development research with a research model using the ADDIE model. The subjects in this study were experts, three teachers, and 68 fifth-grade elementary school students. The data collection technique uses instruments such as an assessment sheet and a questionnaire. The data were analyzed in the validity phase using the Gregory formula, the validity of the tabulation calculation results was calculated to find the percentage, decision making related to the responses of students and teachers using a Likert scale with five alternative answers, and effectiveness using a normalized score showed the level of treatment effectiveness from the score or posttest. Obtained from content and media experts, the overall design is very good, for the response of teachers and students as a whole gets a very positive response, and the effectiveness gets high criteria. Based on these results, it can be said that the electronic teaching materials developed are valid and effective.
