Electrifying Engelmann | e=mc2andallthat

It is a long-standing and melancholy truth that, despite the best efforts of many legions of Physics teachers, many students continue to not only dislike electricity, but to hate it with the white-hot intensity of a million suns.

What we have here, I think, is a classic failure to communicate.

A final fact is that samenesses and differences of examples are more obvious when the examples are juxtaposed. This fact implies that the continuous conversion of examples provides the clearest presentation of samenesses and, differences because it creates the changes that occur from one example to…

When Harold Met William | e=mc2andallthat

Legend has it that in 1988, U.S. Presidential candidate Michael Dukakis opened an election rally in front of a huge crowd in a red state with the ringing words: “This joke will appeal to the Latin scholars amongst you…” He went on to lose decisively to George H. W. Bush.

On that note, this joke will appeal to all the Physics teachers (and other aficionados of the dot-and-cross convention).

For the non-physicists amongst you, this is an illustration of the dot-and-cross convention, which allows us to represent 3D objects on a 2D diagram. The dot represents a vector emerging out of the…

Engelmann (and John Stuart Mill) Revisited | e=mc2andallthat

Even for the most enthusiastic and committed of us, Engelmann and Carnine’s Theory of Instruction (1982) is a fabulously intimidating read.

I have written about some of the ideas before, but a recent conversation with a fellow Physics teacher (I’m looking at you, @DeepGhataura) suggested to me that a revisit might be in order.

In a nutshell, we were talking about sets of examples. Engelmann and Carnine argue that learners learn when they construct generalisations or inferences from sets of examples. It is therefore essential that the sets of examples are carefully chosen and sequenced so…

Physics Limericks: Some Classics | e=mc2andallthat

The following two are, I believe, by famed textbook writer A. P. French

There was a young fellow named Cole

Who ventured too near a black hole

    His dv by dt

    Was quite wondrous to see

Now all that’s left is his soul!

Ms. Farad was pretty and sensual

And charged to a reckless potential

     But a rascal named Ohm

     Conducted her home.

Her decline was, alas, exponential!

I came across this one recently, and I like its subtle cleverness.

Relatively Good Advice

by Edward H. Green

Dear S’: I note with distress

The length of your yardstick is less
