I will say that being an old dog, it was hard for me to start using PPT I was used to writing on the board & being able to engage my students I thought fine. When I started using the PPT, I was amazed at what I could do & get my subject through on a different level. I started experimenting with media & now I can say I am comfortable using most forms. I even have gotten pretty good with the smart board. So old dogs can learn new tricks!
