No, this isn’t a mistake– I’m doing two quasi-polls on academic issues today, because I care what you think… I’m handing back last Thursday’s exams today. The scores on the test were about what I expect, given the material. As I’m looking at the scores, trying to assess the class as a whole, I’m curious… Continue reading Academic Poll: Exam Reporting

Academic Poll: Formula Sheets
In the basement, across the hall from my lab, there are three plastic-covered collages made up of formula sheets from long-ago exams. One of my colleagues let the students in a Physics for Pre-Meds class write whatever they wanted on one sheet of paper to bring into the final, and made art from the collected… Continue reading Academic Poll: Formula Sheets
Course Report: Formal Quantum Mechanics
I left off last time with a brief introduction to uncertainty, followed by two classes worth of background, both mathematical and Mathematica. Class 15 picked up the physics again, starting with an explanation of the connection between the Fourier theorem and uncertainty, namely that any attempt to construct a wavefunction that has both particle and… Continue reading Course Report: Formal Quantum Mechanics
Essential Skills and Experiences?
Like a lot of physics departments, we offer an upper-level lab class, aimed at juniors and seniors. There are a lot of ways to approach this sort of course, but one sensible way to think about it is in terms of giving students essential skills and experiences. That is, i’s a course in which they… Continue reading Essential Skills and Experiences?
Two Cultures in Beginnings and Endings
Not long after I posted my comments about textbook prices, I went to a panel discussion on teaching, where a social scientist made an interesting observation about the ways different disciplines interact with books. In the humanities, the whole point of the class is to discuss the books. Nothing useful can be done until and… Continue reading Two Cultures in Beginnings and Endings
The Swashbuckling Physicist’s Guide to Complex Numbers
Having mentioned this a few times in course reports, I thought I’d throw out a link to my lecture notes (PDF) on complex numbers. This is the one-class whirlwind review of complex numbers from defining i to Euler’s theorem about complex exponentials. To answer a slightly incredulous question from a commenter, this is necessary because… Continue reading The Swashbuckling Physicist’s Guide to Complex Numbers
Lab Reports: Threat or Menace?
I got the last round of line edits on the book-in-progress Monday night after work, but I haven’t had a chance to do more than leaf through the pages. This is mostly because I had lab reports to grade– the second written report is due Sunday, and I needed to get comments back to the… Continue reading Lab Reports: Threat or Menace?
Course Report: Historical Quantum Mechanics
In the last report from my modern physics course, we wrapped up Relativity, and started into quantum mechanics, talking about black-body radiation and Planck’s quantum hypothesis. The next few classes continue the historical theme
Academic Set Theory
Theorem: The set of students who can learn the material of a course without attending lectures or working homework problems is always smaller than the set of students who think they can learn the material of a course without attending lectures or doing homework problems. Years of intense study have so far failed to produce… Continue reading Academic Set Theory
Pedagogical Poll: Good Results or Historical Accuracy?
This week’s lab (well, half of it– the class is so big that I have to run two experiments in parallel) is somewhat controversial, so I thought I would throw this out to my wise and worldly readers to see what you all think. The problem is this: we have two different set-ups for doing… Continue reading Pedagogical Poll: Good Results or Historical Accuracy?
