Multimedia enabled virtual classroom for distance education

The complex construction of online educational systems lies within three key activities, i.e., design, execution, and appropriate post-implementation assessment. However, there is inadequate knowledge with regard to these activities. Effective execution of these three activities demands the use of design and educational models to obtain time proficiency, cost, and high educational quality. The use of online educational systems would benefit from an organized approach to design, execution, and evaluation of students. Therefore, this study proposes a general design of both a model and framework for improving online educational systems for teachers as well as students by taking into consideration accurate assessment and effective evaluation of the learning process. In this study, we use a local area network-based connection for creating a virtual classroom that comprises both audio and video conferencing, which can be used by students as well as teachers. Moreover, we include other features such as moderated online chat between students and a teacher, resource sharing, questioning, survey, feedback, and query posting by students during the unavailability of a teacher. Moreover, we implement audio and video conferencing-based e-learning via real-time transport protocol.
