PP has not. TBH it has made presentations very easy. It's how I presented my research and how I did my thesis defense.
If you are going to teach though I don't think they should be used. My fav style was where my prof just handed out a half filled in handout and filled in the rest on a projector. It worked out very well.
Well its going to be on very rout lecture shit. Catagoris and Scheduels of drugs. Nothing I don't already know about but I have some people in the class that think im an idiot and give me the eye roll when ever I speak. Frankly some prity juvinile stuff for the 'maturity' that o was told was common in grad school.
