The Homework assignments folders have homework sets built by Mike Dubson, Steve Pollock, Oliver DeWolfe, and Andreas Becker. Some of them are basically Griffiths' problems, slightly disguised, or tweaked. I tried to add elements of explanation, sense-making, estimation or approximation, real-world connections, multiple-representations. Some problems come from other texts, or from other faculty at CU. We have not done a very good job of acknowledging "sources" here, my apologies.
Andreas Becker and Oliver DeWolfe wrote problem sets in LaTeX, both LaTeX and PDF versions are available here (see the tex_source sub-directories).
The Homework Observations folder contains detailed instructor notes from homework help sessions. Coming soon: statistics on student performance, on every homework problem we gave this semester. These are very rough – we suggest you look at these if you are considering giving a homework problem from our assignments but are wondering if students found it easy or what aspects of it they struggled with.
The Homework Solutionsare only available by writing to us directly and asking for complete course materials. This is to hide these materials from students. If you wrote to us and have the complete download, then these are in folder 10 "solutions"
As always, if you want to make contributions or improvements, let me know
Notes:
Griffiths' solution manuals are easily available on the web, which was one reason for at least changing the problems enough to make a little more challenging for students to simply "look up" the answer.
