Literature and the Brain by Norman N. Holland
The best article I've read lately is Charles Duhigg's "How Companies Learn Your Secrets" published in the February 16, 2012 issue of the magazine in The New York Times.
And I am still thinking about teaching with the use of messy problems because of the following article:
Carrithers, D., Ling, T., & Bean, J. C. (2008). Messy problems and lay audiences: Teaching critical thinking within the finance curriculum. Business Communication Quarterly, 71(2), 152-170. Please don't be deterred from reading it just because it's about finance. It's really good. Not only that, but what finance students face is similar to what students in the health professions face. For both, they must learn a lot of very technical information and then be able to distill their knowledge and impart it to people (their clients or their patients) who will base important decisions on it (their money or their health). So, I'd like to recommend it to all the HPD faculty.
