Adding navigational links to your PowerPoint presentations adds greater ease of use, a great reference system to use during lecture, and a great review tool. Here is an example of how this works.
In this interactive PowerPoint presentation students can easily learn how to use the JVC digital camera for a Video I Production class. The hyperlinked areas gave students the freedom to get to the information they needed to review in detail instead of going from slide to next slide. This tool was used for many years and still is a great example of using PowerPoint in a non-linear way.
