The Faculty Inquiry Network (FIN) "is comprised of community college faculty from across California, working in teams to investigate a complex problem in basic skills education..." (from Info page). Together, they have produced this beautiful blog which describes faculty inquiry ("a form of professional development") and includes resources and a toolkit. There is also an email subscription available, to better keep current with this project.
Produced by the Commonwealth of Australia, (c) 2008 (with regular updates). This site provides a repository of subject-area toolboxes which can be further customized as needed.
