"Blah blah blah biochemistry (or whatever is at hand)."

"Now a historical example! [Researcher] was investigating [topic highly relevant to lecture] during [historical context]. S/he had a question: [why am I seeing this / what is this thing I am seeing]?"

"They hypothesized [blah, possibly with illustrative diagram / chalkboard doodle]."

"To test this, [famous experiment]."

"When the researcher did the experiment, they saw [results, with pictures / diagrams / charts / animations / chalkboard doodle]. This was [in line with their hypothesis, or surprising]! It turned out that [biochemistry]."

"Therefore, we know [biochemistry] because [keywords relating to historical example]. The take-home message is: [one or two sentences]."

Questions may be - even should be - solicited after any hard return, as well as any other time the teacher sees eyes glazing over.

The take-home is key: what is the core concept? Knowing what the teacher considers essential tells the student what is a colorful but noncritical aside, and what is a key detail necessary for their knowledge base (and passing the test).

The structure is also important: deliver different material in the same way, so students can home in on what you're looking for (context, hypothesis, experiment and results, conclusions, take-home).

This message brought to you by this week's ABO typing example, which managed to do all this except a succinct take-home. (I think it was something about haptens and epitopes, but I'm still confused on the biochemistry.)

Call me a bitter undergrad, but everyone's about to get the pedagogy lecture. (We know I've jumped the shark because I said "pedagogy" with a straight face.)

First: if you are writing on a blackboard, stop talking.

Second: if it's important, put it on the blackboard. Like this: "important term: means this." Corollary: no tangent should be longer than two minutes.

Third: if you are drawing a graph, label your graph, just like freshmen are forced to do in 100-level classes: title, axes, units. If you draw multiple lines on the graph, label the lines.

Fourth: if you put up an equation, put up what the pieces mean. Telling me that No/(Nt - No) = e^-[nF*(psi-psi0)/RT] is only useful if I know what psi0 represents, and also that No is Nopen, not Nzero.

Fifth: if you can't do any of these things, and it's a 400-level class, find your sub-discipline's equivalent of Albert's all-encompassing Molecular Biology of the Cell. Tell your students about it. If it costs more than $150, put it on reserve at the library. You should do this anyway, but if you're hitting your marks in lecture, a good fallback textbook is gravy, rather than essential.

Bonus: powerpoint is like salt. A little is a good thing, but a lot will kill you. Dump it at the door with the rest of the trash.

Bonus #2: I have never seen anyone go wrong with colored chalk, except by forgetting to bring it.

So perhaps I needed to let loose a bit. )

Good news: I wrote my rant! Bad news: I still don't understand voltage-gating in channels. Busted on the procrastination front.
