Acquisition of structured knowledge is a good point of e-learning.
SNS is the place to establish and develop the knowledge gained here. Students can discuss on the community and share knowledge gained from each other. It is also possible to demonstrate their own experiences and perspectives and it will contribute to develop knowledge. New ideas are probably born from that activity.
For example, it is possible that a salesperson who learned marketing knowledge can create an unprecedented sales method by discussing "How to put new knowledge into daily work" with his own successful experience.
Within the community, target existence, rival, or partner existence is spontaneously born. It will be a great motivation for learning.
With the SNS community function, e-learning is not a solitary self-learning, but it becomes effective and exciting as if you learn while discussing with colleagues in the classroom.
