It is important to have students interact via online discussion, however this requires two elements to make it work. First, you must have the instructor involved in helping the conversation move forward. Second, the instructor does not want to "take over" the conversation, but just be involved enough to move it forward by asking pointed questions and ensuring the class response. Though, as an instructor, I ask many questions in hopes of moving the conversation forward I find too many times only the student who began the conversation responds. Has anyone found a way to involve more than the original poster?
