Developing E-Learning Based Remedial Videos to Overcome Learning Loss in Trigonometry

Abstract

Mathematics learning in Indonesia is worrying because it results in learning problems called learning loss. To overcome such problem remedial learning is necessary. The current situation shows the remedial teaching implemented by teachers still uses the conventional method. Therefore e-learning based remedial learning is necessary. The material will be made into a short animation video which then will be uploaded to an e-learning. The aim of this study is to develop remedial videos on the topic of trigonometry which then will be shown to the students who require remedial learning. The method used in this study is research and development using the Plomp model which consists of three phase that are the preliminary research phase, the prototyping phase and the assessment phase. The Readability test includes eight students from one senior high school that are heterogeneously chosen according to the level learning achievement. The remedial videos were tested to students, teachers and a lecturer for the validity and readability. If the results are not readable and valid then the researcher will revise the videos. This study resulted in the video developed to be readable and valid.
