How a power point can be used in the class room?

There are several ways I can think of to use power point in a creative way. One that I like a a lot is the schedule on an old computer or TV, just like the Dali. That would be a great way to keep students informed on when everything is happening.

Another one I could see using would be to make a slide show only presentation, then put several links on a slide containing a question, have the links like a multiple choice quiz. wrong answers taking the user to a slide that says stuff like " nice try, but nope, or try again." then with a link back to the question. This would be a lot of work, but this would be a perfect way to give out a practice test, just a little something for the students to work on.

The course curriculum assignment is something I could definitely see me using in a class. If a sub did have to come in I would be able to tell them the week, and they would be able to find out where the class is and what they are learning about, with hardly any hassle.

I have been thinking on how to use power point presentations for the students, for their assignments. and I'm torn between saying sure they could, perhaps should, use power point for projects, letting it give them a crutch to help the ones nervous about public speaking. But then there is the flip side, of students using it as a crutch instead of developing good public speaking skills.

anyway just my thoughts.
Cheers,
