Getting students to participate and be engaged in the learning process is necessary for sucess in an online class. Group engagement is also very important. This can be done by assigning roles within the group, such as, leader or facilitator, etc. You can also assign portions of the assignment to different members of the group. Students must also realize the importance of online citizenship. As an instructor, you must make sure that they understand the academic honesty policy of the course. This should be relayed in your syllabus.
