I’ve been having students develop portfolios (https://arundquist.wordpress.com/2016/01/14/portfolio-sbg/) and now the oral exams have me randomly picking one of the ~75 problems they have to work throughout the term and they flip to that page. I then stare at it for a minute or so and start to ask probing questions. I tend to focus on things like negative signs because I want to make sure they understand the physics about why it has to be negative.

]]>Please tell me more! Are these the ones that you do in class every couple of weeks (ish)? If I remember correctly, these are public oral exams, right?

What work are you looking over? Is this like a take-home exam? Bret

]]>I think it’s worth understanding metric spaces because they simplify a lot about basic analysis by showing that limits just ask that you get close to a point, and what “close” means can be generalized to interesting spaces like graphs and trees for the computer scientist types among them.

I think they’ll end up looking at libgen.io for their books if they have any sense.

]]>Do you think it is worth having them spending twice as much on textbooks for the class? Pugh costs about the same as Abbott. Or maybe I could copy some of it as Fair Use?
