If you haven't already found it, I think you'd enjoy this site: Science Myths. It has an extensive section on electricity. I think that electromagnetic theory is the least understood area of physics. Feynman even gives the (incorrect) "rolling wave" interpretation of Maxwell's Equations in his physics books, eg. a change in B causes a change in E a "short distance away". Ummm, that would be action-at-a-distance.
Yes, I am a big fan of Bill Beatty. He is not afraid to shake things up. The most important thing he says is that terminology is important. This is especially true when teachin. We so easily toss around terms such as current, power, energy that the kids have no real concept of yet. One of his pet peeves is to say that current flows. Sounds good to most of us since we understand what it means. But to a kid, there is this thing called 'current' and if 'flows' in wires. Sort of like 'water' that 'flows' in a river. Then we mention 'charge' and tell them that 'flows' in the wire. Oh, so charge IS current since they both flow?? That's what it sounds like to them. That is when they shut down since the language is not consistent.
I make sure to always say 'charge flows' and 'there is a current in the wire'. Just as we would say 'water flows' and 'there is a current in the river'. Sounds picky to us, but the kids appreciate the consistent use of the language.
I like these quotes:
"Lest you think that I am quibbling over minor points of language, I note that in my experience many of the misconceptions people harbor have their origins in imprecise language... Precise language is needed in science, not to please pedants but to avoid absorbing nonsense that will take years, if ever, to purge from our minds."
- Dr. Craig F. Bohren, from his "Clouds in a Glass of Beer:
Simple experiments in atmospheric physics"
"(language) becomes ugly and inaccurate because our thoughts are foolish, but the slovenliness of our language makes it easier for us to have foolish thoughts." - George Orwell
"The search for the MOT JUSTE is not a pedantic fad but a vital necessity. Words are our precision tools. Imprecision engenders ambiguity and hours are wasted in removing verbal misunderstandings before the argument of substance can begin." - ANONYMOUS CIVIL SERVANT (from Roget's Thesaurus Webpage)
"Many errors, of a truth, consist merely in the application of the wrong names of things." -Spinoza
