Syllabus (the book)

I just read Syllabus by Lynda Barry. It is a set of syllabi and daily in-class instructions, along with some reflections, from a few years of teaching cartooning and writing at Wisconsin. It is a combination of hilarious and insightful, both about learning to draw and cartoon, but also about the practice of teaching.


A page from Lynda Barry's Syllabus.

The syllabi and daily exercises include many great practices. For example, when students are listening to something (being read or previously recorded), she has them either draw tight spirals in their notebooks or else color in a line drawing. She has the students sketch in non-photo blue pencil and ink in later; it reduces inhibitions. She has simple forms for students to write daily diary or journal entries so that they make close observations of the world, in words and pictures. She loves most the students who have never drawn (since childhood), and she makes exercises that capitalize on their newness (and defeat those who are more experienced at rendering), like forcing them to do drawings in increasingly short time intervals.

The book is hilarious in part because she shows lots of great student work (it is not clear she has proper permissions here, because she does not individually credit each student drawing), and because the whole book is a collage of drawings, writings, and found objects, in the Lynda Barry style. I doubt there is another book out there on teaching that makes you laugh out loud all the way through.

A great question for me is what of Barry's practices could carry over to a class in Physics?

air resistance, again

I should stop complaining about air resistance, but I can't help myself! I am teaching this semester from Kibble & Berkshire, and in Chapter 3 there are problems about air resistance that use speeds of around 100 meters per second and an atmospheric drag law that is proportional to velocity to the first power. I don't think there is any physical system that could have these properties: If you are small enough to have viscosity matter, you can never go 100 meters per second. Well, I guess molecules can go that fast, but (a) that isn't what the authors have in mind, and (b) molecules aren't really well described by continuum mechanics!

the answer "that question is ridiculous" must be accepted

My friends who work in education of the young (the 'fuzz included) like to quote studies that show students answering without comment or concern questions like "Farmer Jake has 13 sheep and walks them 21 miles. How old is Farmer Jake?" There are many mixed-up reasons for this problem; some relate to rote learning; some relate to the artificial dichotomy set up between reading and math; some relate to the decontextualized ways we teach math; some relate to the testing environment that saturates schools; and so on. I feel all these things!

Imagine we want to see students using their common sense and their judgement with every question they consider and answer. I think that would be good. How do we foster this kind of thinking and exercise of common sense? I think we have to let the students call "bullshit".

Here's an example: "Johnny has twelve toy cars. He gives eight to Frances. How many does he have left?" Obviously we should accept the answer "four". But we should also accept the answer "No way! Who would give more than half of his toy cars to someone else?" If we don't accept that answer, we are saying to the students "calculate without thinking". That might be okay for quantum physicists (though I disagree), but it isn't okay for the rest of us.

don't teach math!

In a nice conversation about writing for education, Adam Gidwitz (the author of A Tale Dark and Grimm) pointed me to The Mathematician's Lament. The book makes (much more clearly than I) a point I have been making informally for years: If you want students to know and love math, you definitely should not teach it in school! (Same for literature.) The mathematics requirements in school empty the subject of its meaning and point, and are useless to boot. How many non-scientists use the quadratic formula, ever? Discovering the formula would be fun, using it is a drag (and exceedingly rare).
