{"abstract":"Due to student demand for online distance learning and academic institutes' desire to promote and deliver courses across the globe, dynamic teaching and learning in Senior High School has moved from traditional class room, face-to-face learning environments to more interactive and collaborative environments in today's digital era. This paper focused on the development of virtual learning environment in teaching robotics conducted during the second semester of the school year 2020-2021 at Rizal National Science High School, Binangonan, Rizal. The study used developmental, descriptive and experimental methods of research utilizing evaluative, qualitative and two-group pretest-posttest research design. Based on the findings, the developed virtual learning environment in teaching Robotics were very highly acceptable as evaluated by the teachers inclined in Robotics and experts in terms of interactive content, instructional feedback and assessment, navigation, visual design, learner guidance and support, learning strategies design, accessibility, learnability, content, activities, usefulness and style and presentation. The results showed that both experimental and controlled groups generally increased their level of performance in the different lessons in Robotics. The developed virtual learning environment improved and increased the performance of the learners in Robotics. The findings point to a potentially promising pedagogical approach for integrating formal and informal learning using a virtual learning environment, as well as students' support for self-regulated learning, in order to meet the educational institution's needs for creative thinking and flexible learning.","abstract_source":"original","authors":["Marlon Sta.Catalina","Romulo Arada","Glicerio Estacio"],"date":"2022-12-07","doi":"10.5281/zenodo.7408361","id":829,"issue":12,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"7b39487126614e456b5148a8453526a088b8007a18785596b53c4192126450ad","schema":"scimatic-article/1","title":"Development of Virtual Learning Environment (VLE) in Teaching Robotics for STEM Students","volume":5}
