A big part of being on top of your game in instructional design is learning how to use productivity software. Because PowerPoint is so prevalent, most eLearning authoring software is compatible with PowerPoint in some way. Captivate allows for importing PowerPoint and maintains all of your animations, slide notes, and much more. Storyline and Articulate also have PowerPoint import capabilities. Intime, I will have a series of free tutorials on how to use Captivate, Storyline, and Articulate, which will include the PowerPoint functionality.
For those brand new to the field, that do not have Microsoft PowerPoint, you can use this blog post to begin learning the basics. Please comment with additional video tutorials you would like to see, and I will add them to this playlist.
