This is a key concept to learning. Students often times need encouragement and someone there to back them up. Computers and other systems could not replace the human interaction involved in a traditional classroom. This is a very important and necessary component when dealing with education. By interacting with not only teachers, but also peers, students are able to learn social skills that enable them to interact with many members of society.
Students learn to interact with others, to share and how to make friends.
They learn discipline and other skills that are hard to teach elsewhere. The involvement in extra-curricular activities is something that only brings positives to students' lives. Events such as forensics, sporting events, band and organized groups teach the children the importance of working as a team. Children also learn of many problems or obstacles they have to pass when growing older. By changing our educational system to virtual classrooms, these extra activities would also be taken away.
