I have used fun in my lectures for several years. The students attendance , grades and grasp of the material were never better. We should all try to get students to interact with open ended questions and add fun to our lectures.

I agree with other teachers that the use of power-point can be an added tool but teachers who use it 100% of the time this is "Death by power-point". Have FUN with the students don't put them to sleep ZZzzzzzz.
