Grading day


All of my students are above average, and handsome, too

The students have survived their first genetics exam, everyone passed, hooray! Now I have to figure out went wrong in the problems they missed, and shore up their weaknesses in the next week.

First thing I notice is that they are rock solid on simple Mendelian genetics, but that’s not a surprise. Mendelian genetics is dead easy, which is why I have to roll my eyes when I see racists and eugenicists babbling out terms from high school genetics — it’s all the later, more sophisticated stuff that trips them up every time. Getting cocky about the basics is a sure way to fail when reality makes its ugly appearance.

What I really have to work on are probability and statistics. Some of the students are unclear on what a p value implies, and they’re getting tripped up by simple things, like the binomial theorem. I had no idea when I got my biology degree that I’d end up having to teach math!

(Really simple math, too. High school teachers, make sure your students are aware that biology is not a math-free discipline!)

    No surprise there. Physicians mostly don’t know what a p value is and they don’t understand Bayes theorem. Actually, I would say that most people who do clinical research don’t understand the meaning of a p value, which by the way I would like to see a lot less of. Go with Bayes.

    Isn’t grading one of the most dull, soul-crushing element of teaching ? (my sister teaches chemistry)

    The upside must be learning about the progress of former students ( if they keep in touch).
    Anyway, I found math to be one of the more fun activities of university. But it helped if you had friends you could consult when you inevitably got stuck.
