PowerPoint presentations have been instrumental in focusing key concepts with visualizations, but when placed on the internet with traditional methods, these blunt points can become meaningless to many students. A variety of software is available to quickly and affordably convert PowerPoint into interactive audio/visual web files. If you have ever been enlightened of the instructional value of audio podcasts, you can just as easily develop your old PowerPoints into online audio/visual presentation using programs like Articulate Presenter, SWiSH Presenter, and Macromedia Flash.
