Third, technology must be relevant and interactive to the coursework. A faculty member who uses PowerPoint in a lecture is not using technology interactively. Students need a practical use for technology, whether to manipulate data or to explore the inner recesses of the human body without cutting up cadavers. Students need to communicate quickly with each other, but in a centralized manner. That is why message boards are great. Members-only message boards allow students and faculty to communicate with each other. Plus, faculty members can use the course lockers during lectures and provide information outside lecture for students to explore at their own pace.
