This one could be particularly useful in a physics course, or a unit on the history of science. Richard Feynman may be most famous, pedagogically at least, for his invention and use of Feynman Diagrams. Most discussions simply mention the things, though a few attempt short explanations. Rare is to find a good example of a Feynman Diagram, to see just what they are and how they work. Tufte and Schwartz offer a bunch:
Feynman Diagrams, an Imagequilt from Tufte and Schwartz
Just how fitting is it that Tufte uses the words of Feynman, probably more famous for Feynman diagrams than the work that got him a Nobel?
“Picture of a Feynman diagram, inscribed by Richard P. Feynman to me [who MFB has not identified], in my copy of Volume 3 of his Feynman Lectures on Physics (Quantum Mechanics). Picture taken by self. if you can’t read the symbols, they are \gamma_\mu to \gamma_\mu and 1/q^2 .” Wikipedia image

National Lampoon once ran a cover of a nice, spotted mutt, tongue out, looking sideways at a pistol pointing at its head. There was a sort of a caption: “If you don’t buy this magazine, we’ll kill this dog.”
That’s one way to try to boost circulation! I first saw the magazine on the rack in a small pharmacy in Colorado Springs, across the street from Colorado College, between rounds of the Colorado College Invitational Debate Tournament. Being short of cash and in sore need of eye drops, I looked at the magazine but put it back on the rack. The woman at the cash register watched me carefully. When I got to the register, she said, “You know, they’ll do it, too! They’re just the sort of people who will kill that poor dog!”
(I imagine that woman has led Colorado Springs’ dramatic move to the right in politics.)
The publishers got that woman’s attention, didn’t they?
In the middle of the 19th century blackboards were all the rage. According to Pennsylvania State University engineering communication professor Michael Alley, it was common for universities and research institutions to proudly advertise that they had the only slate writing board in a 100-mile radius. Scientific lectures became more engaging than they’d ever been.
More than 150 years later, there’s still room for improvement. “People are not anywhere close to tapping the potential that a PowerPoint presentation offers,” Alley says. “We have a tool that can do an incredible amount, and people just waste it.” Who hasn’t been lulled into a somnolent state by some well-intentioned scientist presenting his research to a captive audience by reading a seemingly endless stream of bullet points?
Any media, done well, can be wonderful. P. Z. Myers’ paean to Prof. Snider and his color chalk artworks reminds us that even a chalkboard can be a place of art, in the eye and hands of someone who gives thought to the work and practices the skills necessary to communicate well. Looking around my classroom today, I note that better than half the whiteboard space features paper maps held to the board with magnets (which the kids like to steal).
The piece in The Scientist relates useful ideas to help somebody who wants to make a better, less sleep-inducing, communicative PowerPoint (or better, maybe, KeyNote) presentation.
Unplug, think, and write
According to Galloway, using PowerPoint to make a great presentation starts with powering down the laptops and writing out an outline on index cards or a legal pad. “People have to shut off their computer and go away as they’re writing their PowerPoint presentation,” he says.
Establish your assertion Alley says that he starts planning each slide by writing down a single sentence stating the idea he wants the audience to take away. “You have defined what it is you need to support that statement,” he says. “That’s where it starts.” Alley adds that the sentence should only take one or two lines, should consist of only 8–14 words, and should appear in 28-point font when inserted in the final PowerPoint presentation.
Assemble the visual evidence Let the assertion sentence for each slide guide your decision as to which visuals should accompany it. Use “explanatory images”—not decorative or descriptive images—to support each assertion, says Joanna Garner, assistant professor of psychology at Pennsylvania State University. When describing the context or methods of your research, photos and movies are ideal pieces of evidence; when presenting your results, elements like graphs, tables, or charts (appropriately highlighted to emphasize key points) will do the trick.

We've been soaking in the Bathtub for several months, long enough that some of the links we've used have gone to the Great Internet in the Sky.

My blog, Millard Fillmore's Bathtub, is a continuing experiment to test how to use blogs to improve and speed up learning processes for students, perhaps by making some of the courses actually interesting. It is a blog for teachers, to see if we can use blogs. It is for people interested in social studies and social studies education, to see if we can learn to get it right. It's a blog for science fans, to promote good science and good science policy. It's a blog for people interested in good government and how to achieve it.
