I prefer Powerpoint over white/blackboard because:
1. People make mistakes on the whiteboard
2. You can't save it and review later
3. Even if you write everything down, it would still be less
information than what someone could add in the Powerpoint
4. Powerpoint is much more legible
5. It is easier to go at your own pace during and after the presentation if someone is using a Powerpoint. If someone is using a white/blackboard they are going to erase the last part very quickly after they finished writing it down.
- keithpeter 13y agoSuggest you look at interactive whiteboards or similar. Best of both worlds potentially. See my comment up the page.
- yeukhon 13y agoThe core issue is preparation and this is something spontaneous whiteboard lecture can't beat a well-preapred powerpoint presentation.
- baq 13y agocompletely disagree. my calculus and algebra professors never used powerpoint on any lecture and they were extremely well prepared. those were the best classes on the whole uni.
- lqdc13 13y agoSeveral of my graduate math professors sometimes failed at solving Calculus problems on the board because they made a mistake somewhere and couldn't evaluate an integral. In Bio classes, almost everyone used Powerpoint. Those who did the blackboard approach had the worst lectures mostly because they wrote down very little and just talked about concepts.
- scotty79 13y agoSeeing Professors fail at what they teach is very instructive. You see that they are not replaying prerecorded material from their brains.
- yeukhon 13y agoYour disagreement is not very convincing IMHO. How do you know other teachers didn't use whiteboard? Maybe your professors are articulate, experienced instructors. Also, your teachers probably teach the same course over and over. They don't do spontaneous, once-in-a-life-time lecture to you. They know what they have to teach today and tomorrow. They know exactly what proof to use. Unlike university lecture, the discussion forum at LHC in the article are probably one-time open brownbag. They raise an interesting question, they talk and they leave the room.
- keithpeter 13y ago"They don't do spontaneous, once-in-a-life-time lecture to you." True, but you do vary presentation to allow for audience. I use 'room temperature' questions early on; rows of confused faces and I go into the slow siding; rapid fire answers and extensions and I shift into the express route. Mixed reactions and I have been known to split the whiteboard down the middle. So less a linear video tape and more a series of responses deployed depending on feedback from the class I am teaching below University level though, and smaller classes (15 to 25 people).
- yeukhon 13y agoTrue, completely agree. But that's a skill :) you could have a teacher writing on the whiteboard for 45 minutes and zero interaction. A similar analogy would be kids abuse the right to start out an introduction paragraph with a quote or a question.
- Too 13y agoMost universities I've been to have 9 black/white-boards in a lecture hall. No risk of erasing what was just written because you run out of space. In case you haven't seen this configuration, the boards are mounted on rails that allow them to slide up above each other when you're done with one, with three of these set ups next to each other giving you a 3x3 grid of blackboards. Smaller lecture rooms have a 2x2 grid which lasts quite long also.
