Reading Recommendation

I'm always amazed at the new meaning we find when we go back to reread something old a new. These past two days, I have been re-reading the following lecture series by David Hammer:

Hammer, D. (2004). The variability of student reasoning, lectures 1-3. In E. Redish & M.
Vicentini (Eds.), Proceedings of the Enrico Fermi Summer School, Course CLVI (pp.
279-340): Italian Physical Society.

Lecture 1: Case Studies of Children's Inquiries

Lecture: 2: Transitions

Lecture 3: Manifold Cognitive Resources

I highly recommend them.
