As being a lecturer by profession, there has been many discussions on the pros and cons of teaching with different media. One of the most controversial issues involve the use of PowerPoint as the main supporting media for the instructors. Though there is a huge push towards PowerPoint, there are certain issues that I don't agree. One quote on a discussion on this issue goes as follows:

"Speaking on behalf of math instructors, there's a reason we use chalkboards.

Pacing.

Writing out your points as you make them forces you to slow down your exposition. This makes it easier for your audience to digest what you're saying, and also gives them time to take notes. Using premade slides or a powerpoint slideshow lets the presenter run unchecked, and the audience tends to zone out rather quickly. I could cover three times the material in a lecture if I used premade slides, but my students would get so little out of it that I might as well have said nothing at all."

As noted, another issue to ponder on, and why there is never any absolute answer in this world!
