If you develop elearning courses through a rapid development tool (Articulate Presenter, Adobe Presenter, etc.), consider subscribing to Articulate's blog "The Rapid eLearning Blog." It's a fabulous resource for developing better courses using these tools. Actually, its content often applies to developing any type of learning program. Today's post is on creating learning objectives.
BTW, here are two examples of virtual presentations I've done in Articulate. They are very basic, and the tools let you do a LOT more (incorporate quizzes, video, etc.), but they'll give you a feel for the potentials uses, I think.
I'm becoming a real fan of these rapid development tools. They use Powerpoint as their base, so yes, the output can be horribly boring just like some live presentations, but remember that is the presenter's, not the tool's fault!
