There are some who would say that PowerPoint® is a teacher's best friend. After all, here is this simple little (ok, not so little …) program capable of displaying any media you choose, and all you need to do is drag and drop! If you're giving a linear presentation, and chances are you are, then this is all you need to know.
However, there are other times when a linear presentation just won't do. Perhaps you need to go to a certain slide during a question and answer session. Better yet, what if you want to create a quiz? What to have some mathematical computations going on in the background to make the whole presentation more interactive? Sure, go ahead!
Oh, wait … they didn't cover that in the faculty in-service, did they? Oh well, what do you expect from fifteen minutes of instruction and a half hour of "play around with the program" time. Lucky for you, there are enough people out there who have not only figured this stuff out, but are willing to share. Among them are the good people who maintain the Internet For Classrooms website, which happens to have quite a few tutorials on it.
Scrolling down to the "Advanced" section of the tutorial list, the instructions on how to create invisible buttons caught my eye. Wait, invisible? What good is that? Bear with me here, I'll get to that.
First of all, the tutorial is written totally in html code – although at the end a link is provided to a sample PowerPoint. The text includes many, many pictures that show in detail exactly what needs to be done. These pictures are simply wonderful – in fact I think that I wouldn't even need to read the tutorial so long as I could look at the pictures. These pictures are obviously screen captures from an older Windows operating system, but I won't hold that against them. They were just planning to help the largest percentage of PowerPoint® users possible. The Macintosh version is still similar enough to make this tutorial useful to me.
So what could I use this for? Well, it's rather convenient that you asked. Something I routinely do as an Art teacher is show artwork to my students. Normally this requires that I be there to point and talk. With this setup, however, I could section off different parts of an artwork to be buttons and have each button link to a different slide. When students see a section that interests them, they can click on it to learn more about it. If I'm lazy and don't want to make multiple slides, I could have the buttons play audio files where I talk about that section of the artwork rather than force them to read.
I could put a bunch of artworks like this together to make whole chapters of informative multimedia books, then go take a break while the students all use my PowerPoint® presentations and become so enthralled that they fail to notice my absence … or rather, maybe I should stay in the room in case anyone has any questions for me. Yeah, that's what I meant.
