I disagree with the author, I do not believe powerpoints are evil, in fact I believe that they are an enhancement to instruction. However, the type of powerpoints presented can make a difference. It is one thing to give information via powerpoint, but to overload it with words is another thing. By using a power point you can magnify important information in a short period of time versus reading a whole chapter with thousands of words.
Powerpoint's accelerate the learning as well as engage the audience. Powerpoints are also an easy way to use pictures to reinforce the lesson. By creating a visual you are catering to other learning styles. I have used powerpoints and also converted them into activ board flipcharts for another engaging technique. So therefore, I believe powerpoint presentations are more effective and not evil.
