and Johnson (1991) describe award-winning software developed by faculty members. Many software vendors offer demonstration disks that illustrate many of their products' features. In addition to working with the demonstration disks yourself, invite students to give you feedback on the product.
After purchasing software for student use, you should invest the time necessary to maximize its benefit to students. Some class time (or special sessions in a computer lab) may be needed to teach the students how to use the software effectively. If students will use the product outside of class, introduce the software to the staff at the campus computer labs, so that they will be prepared to answer students' questions. Faculty usually need to develop "courseware" to help guide the students through the software.
The great advantage of multimedia systems is that the combined audio and visual explanation helps students learn and remember. But to avoid student frustration with interactive systems, instructors should make their expectations clear and should provide opportunities for students to get assistance.
