Development and Validation of Video-Mediated Lectures in Science 3

The primary objective of Science Education is to develop scientific literacy among learners that will help them to be ready in becoming productive citizens of the community. However, the COVID-19 pandemic struck the country, thus DepEd restricted to conduct face to face classes in schools throughout the country. As a result, different learning modalities were used to continue education. One of the learning modalities used was Printed Modular Distance Learning. This study aimed to develop and validate video-mediated lectures for Science 3 to address one of the problems encountered in Printed Modular Distance Learning which is the low mastery of the topics in Science. The researcher utilized a research and development design to complete this study. The respondents of this study were Grade 3 teachers and learners from Mulanay District. An evaluation sheet developed supplementary material. Results show that the developed video-mediated lectures for Science 3 received a 3.86 raiting from teacher-respondents, a 3.78 rating from validators, and a 3.90 rating from learner-respondents which are all very satisfactory. Moreover, the video-mediated lecture was found to improve the science performance of the Grade 3 learners. Hence, this study recommends using the developed material in a wider scope to further determine its effectiveness and validity.
