In the present work we have made a systematic study on various issues and challenges in ubiquitous teaching learning methodology.
Due to massive development in IT the entire teaching learning process has been changed. The open learning and distance education
methodology has drastically changed the teacher student relationship. In open learning system there is no fixed class room concept. The
teaching learning process is now transformed towards student centric rather than teacher centric. The new challenge has come i.e. how to
prepare learning material appropriate for ubiquitous learning environment. A thorough revision is required for preparing learning material for
ubiquitous environment. The present work shows us the different methods used in ubiquitous learning environment and also its merits and
demerits. (Abstract by authors)
