New weblogs

Here are some new weblogs that I have been checking:

Jason Lutz is a student of mine. He has not posted a lot, but that is probably because he is in the process of writing his thesis. He is studying group bases: A group G has a basis (a_1,\dots,a_n) if for every g \in G, there exists a unique n-tuple of integers (b_1,\dots,b_n) with 0 \leq b_i < o(a_i) such that g=\prod a_i^{b_i}. He is looking to see when a group has a basis.

Joe Bower is a K-12 teacher who appears to be, like me, a fan of Alfie Kohn’s work. He frequently writes about the affect of grades and homework on students.
