At first glance, teaching a class without the ability to see and hear the students in person appears daunting. The enlightened, quizzical, or stony facial expressions, the sighs of distress or gasps of wonder, and even the less-than-subtle raised hands or interjected queries that constitute immediate feedback to a lecture, discussion, or clinical situation are absent. Yet the proponents of online instruction will argue that these obstacles can be overcome, and that the online format has its own advantages. In the online experiences documented in the "Net.Learning" (www.pbs.org/netlearning/home.html) videotape, which our seminar viewed early in the year, Peggy Lant of the California Polytechnic State University, San Luis Obispo presented a striking example that occurred in her class' online discussion of civil war. One student's comments were especially gripping as she had just survived a civil war in her home country. Shy students who have trouble participating in a classroom discussion are said to feel more comfortable in an online setting. The ability to sit and think as one composes a question or comment also can raise the quality of the discussion. Susan Montgomery at the University of Michigan has developed an interactive website that addresses diverse learning styles through the use of multimedia (Montgomery, 1998).

"Web 2.0 technologies are fundamentally reshaping and realigning many aspects of the communication loop: the people with whom teachers, students, and parents communicate; how they communicate; what they communicate about; and where and when they communicate."
