But the real value of interactivity doesn't lie in the number of physical interactions. It's about the depth of cognitive engagement these interactions can ignite.

In his inaugural attempt using the application, Ferriter posted VoiceThreads about a variety of topics online, encouraging students to comment on them voluntarily on their own time. He got dozens -- even hundreds -- of comments on each. It was a revelation. "I can basically extend my classroom," he says.

Ferriter says more students participate more actively in digital discussions than in the classroom. "You don't have to be the loud one or the popular one," he points out. When he asked his students about their online involvement, he said they cited the sense of safety: "They can think about their comments beforehand." They also liked the fact that any VoiceThread has multiple conversations going on at once. "In a classroom conversation, there's generally one strand of conversation going at any one time, and if you're bored by that particular strand, you're completely disengaged," says Ferriter.

The CREST+ model, a model for writing effective online discussion questions, covers the cognitive nature of the question, the reading basis, any experiential possibility, style and type of question, and finally ways to structure a good question.&nbsp; This model encourages students to participate in online forum discussions, provides a template for new online faculty to use in creating effective discussion questions, and promotes a higher level processing of the material.
