Two li'l videos for Project NExT
In response to Dave Kung's call for crowdsourced contributions to a Project NExT session on time management, I just made the following two videos that I thought I'd share here.

A combinatorics thing
So, a while back, a student did a thing in discrete, which was wrong in an interesting way, and I wanted it to be simpler to get to the right thing than it was, which made me think a lot about what happened. Here we go.

We can create positive student ratings of teaching. Here's (maybe) how.
Notable academic Twitter person Terry McGlynn recently wrote a blog post arguing for changes to the structure of student ratings of teaching (SRTs) that would make them more useful. While I entirely agree with the premise that SRTs as currently constructed aren't particularly useful, I'm not sure I'm on board with the rest of the argument. In particular, I got to wondering along two parallel tracks:

Let's learn Lagrange multipliers by hiking
So here's the problem: You want to optimize some function $ f(x, y)$ subject to the constraint $ g(x, y) = k$. The method of Lagrange multipliers says that you can do this by solving the equations $ \nabla f = \lambda \cdot \nabla g$. But wait, why?

Some words about clickers
Recently a friend of mine sent an email to a list I'm on, asking for advice for teaching a 200-student class in some kind of non-boring way. In particular, she asked about clickers, and since I've used them before, I wrote some words back (at like 6am in Germany because of jet lag; I'm here for ICME). I decided to edit those words into this blog post for more people to read.

[RUME 2016] Borrowing from linguistics: Metonymy and linear transformations
Here's part 2 of my “borrowing from linguistics” series.

[RUME 2016] Borrowing from linguistics: Rina Zazkis and the superscript -1
So, to begin with, let me introduce this sequence of blog posts tagged [RUME 2016]. I was recently awarded a travel grant to the ICME conference coming up in Germany. Part of the requirements for this award is that I'm supposed to help disseminate stuff I learn at that conference, so I decided to practice / build readership of this blog by blogging about RUME talks I found particularly fun and interesting. I've got basically three blog post topics (which may span multiple posts) in my brain, with a fourth that may come later.

What I did when my grading load became completely unmanageable (because of course it did)
So, uh, then this happened, about 6 or 7 weeks into the semester:

Specs-based grading in my calculus classes
Okay, so I decided to switch to specs-based grading (SBG) for my calculus classes this year.
