I used the slides below for a presentation I gave to an advanced writing course this past September. It was created in Keynote and I presented it using the Pointer app for the iPhone as the clicker. It won't make much sense to you by looking at the slides alone, because these slides were simply a visual enhancement to what I was saying as the presenter. This is an important concept to remember when designing your own presentations: the students should pay attention to you, the teacher, and should only refer to your slides when you want them to.
I am working on a stand-alone presentation for Slideshare that will introduce Brain Slides without the need for my explanations as you click through the slides. I will post it soon!
