As instructors design or redesign their courses to incorporate emerging technologies they may find that their role and that of their students change. In the example of an online course where there is “no there there,” a student cannot sit passively at the back of the classroom. To be present and seen in an online class, students must be active and involved. Similarly, an online instructor cannot stand in front of the class and conduct a lecture. Because the online environment differs from a physical classroom, the instructor’s role changes as well. For some instructors, shifting from a lecturer to a facilitator role can be a major change in teaching style. Facilitating interactivity in an online course places the instructor alongside the students instead of in front of the classroom. Designing courses with activities that encourage collaboration, communication, and project-based learning can help instructors step out of the lecturer role. Web 2.0 technologies can be a resource for instructors as they construct new modalities in how they teach and how their students learn. Interactivity can be stimulated by a variety of techniques, ranging from posing questions to be discussed in groups to involving students in projects that include the creation of wikis, blogs, and podcasts.
