Attack of the PowerPoint-Wielding Professors

theodp writes "A CS student blogger named Carolyn offers an interesting take on why learning from PowerPoint lectures is frustrating. Unlike an old-school chalk talk, professors who use PowerPoint tend to present topics very quickly, leaving little time to digest the visuals or to take learning-reinforcing notes. Also, profs who use the ready-made PowerPoint lectures that ship with many textbooks tend to come across as, shall we say, less than connected with their material. Then there are professors who just don't know how to use PowerPoint, a problem that is by no means limited to college classes."

It Works If The Professor Made the Slides

[curmudgeon99]

Speaking as a former professor who has written two entire semesters of Powerpoint lectures in Java, I think the medium is especially effective if the professor knows the material. I gave away my lectures and posted them online forever, so my students loved them. I also do not use powerpoint as just static slides. I use the animation feature to simulate the execution of code, showing (not telling) how variables are handled, how pass by value versus pass by reference works--things like that. It is really valuable if the professor is not a lazy sack of shit. That's the real problem--lazy professors. Profs who write their own lectures are anything but lazy.

Chalk talk rules

[Dynetrekk]

I've got a masters degree in physics, and I'm now teaching as part of my duties as a PhD studies. At my university, most professors give "chalk talks", and some use presentation software. In my experience, presentation software lets the lecturer skip quickly ahead before the students have time to make up their mind about "what just happened", and don't have time to take notes. During a chalk talk, the speed of progress is limited by the time it takes to write up that big nasty equation, and the lecture proceeds at a natural pace. Most importantly, the students more easily see how you think while doing a calculation; if using a powerpoint slide, forget that.

Conclusion? Chalk Talk rules for fundamental science teaching. Powerpoint is probably OK for management theory classes.

o What's Wrong With Powerpoint

[BigBlueOx]

Today we're talking about what's wrong with Powerpoint.

o And Why It Should Be Banned

And why its use should be banned.

o Speakers just put up bullet list and then read from it.

The biggest problem is that speakers put up a Powerpoint bullet list and then just read from it.

o Like their audience is illiterate or sumpin.

Like they think their audience is a bunch of illiterates or sumpin.

o Powerpoint presenters also say things like "actionizing our solutioning".

Also, Powerpoint seems to encourage speakers to say things like "actionizing our solutioning".

Re:Most professors guilty?

[digitig]

Yes, I had one professor who:

• Required attendance at all lectures to pass the coursework element
• Locked the door at the start of the lecturers, so that latecomers would fail
• Required purchase of his textbook
• Simply read a chapter from the textbook in each lecture
• If asked a question, would simply re-read the relevant paragraph

Apparently he was doing some highly lucrative and cutting-edge research, which is why he was kept on. The problem isn't powerpoint, the problem is professors who can't (or can't be bothered to) teach.

Re:Most professors guilty?

They are either there for doing research and thus don't care about learning or they aren't sure what they are doing there and just needed a job.

You're confusing "All University Professors" with the elusive and endangered "Tenure Track Faculty". Most professors nowadays are employed as sessional instructors. That means that they are working part time on a contract which only lasts for a single semester, have no job security, no benefits of any kind, limited access to resources such as office space or the library, and are typically paid next to nothing.

Any illusions they may have had about doing actual research in their field should have disappeared after their first semester of being exploited, and if they really "just needed a job" they would have been better off serving drinks or flipping burgers. The hours and pay are a lot better and at least there would be some possibility of career advancement that way.

This is nothing new, but it's getting worse every year. Consider Allison Dube, at the University of Calgary. Despite teaching at the same school since before many of his students were born, working full time hours and winning numerous awards for excellence in teaching, he can barely afford to continue working.

"Telling the story of his first contract with U of C, Dube explains that he earned about $25,000 for one year's work--or five half-courses. Thirteen years later, in 2002-2003, his earnings have actually gone down, even though he is teaching the same number of courses with about four times more students."

"Poor economic conditions for faculty hiring have prevailed on and off since the 1990s. As a result, permanent, second-class faculty pools of sessional workers have developed in otherwise "excellent" and "academically free" postsecondary institutions. As one administrator put it, "As long as the administration can pay sessionals, why would they give a term appointment? They can get everything done sessionally. It is cheaper... I think that people are surprised when they find out how bad it really is. Especially 15 years with no job security or benefits.""

All this, and you're pissed about your professors having the temerity to not prepare elaborate Broadway productions for every single lecture? Try this: Dig around in your pockets for all the loose change you can find and put that on the table along with five pieces of paper and a broken pencil. Now, quit your job and using only the resources in front of you design and teach three full year courses on microprocessor design, quantum theory, and the history of art in the Spanish Netherlands. When you are done you may treat yourself to a cheese sandwich.

Those are the conditions that your professors are working under. They're not lazy, they're not there just for the money, they're working as teachers because they really want to. Only a complete idiot would subject themselves to that kind of job if they didn't. If you want to be annoyed at anyone for the poor quality of lectures you have been forced to sit through, get annoyed at the University administration for treating their staff like dogs.

Worse than dogs, really. At least the dog gets fed.
