Abstract
•Annotation facility on slides from both students and educators are explored.•Live broadcast of a lecture to multi-class is realized by real time mixture.•Students are highly in favor of annotation facility.•High internet speed is required for live broadcast using real time mixture.
The availability of 3G and 4G technologies coupled with tablet PCs and smart phones makes the communication and learning system easier. In engineering education, these sophisticated technologies can bring immense advantages to the methods of delivering and acquiring knowledge. In this paper, we focus on facilities of a smart class environment for engineering education that can improve the co-learning procedure. We particularly emphasize the use of 3G and 4G technology in a smart class.
