In effect, each student has a private instructor. A uniform and consistent presentation is delivered - An impossible task with traditional lectures and labs. If a feature is not clear, a student need only back up and view it again. Many students know some of the applications covered in the course. These students can proceed through some segments at an accelerated pace.
Computer use is optimized.
CD tutorial disks emulate the Microsoft applications, allowing students to review modules on their own computers even though the Microsoft application is not installed on the computers.
