A comprehensive study on online teaching-learning (OTL) system and platforms

Abstract

Online Teaching Learning (OTL) systems are the future of the education system due to the rapid development in the field of Information Technology. Many existing OTL systems provide distance education services in the present context as well. In this paper, several types of existing OTL systems are explored in order to identify their key features, needs, working, defects and sectors for future development. For this, different aspects, types, processes, impacts, and teaching-learning strategies of various OTL systems were studied. In addition, the paper concludes with some future insights and personal interest in the further development of OTLs on the basis of previous research performed
