I think what you're looking for, at least to start, is the University of South Carolina National Resource Center for the First-Year Experience and Students in Transition
. They have a ton of resources, publications, links to sample syllabi, etc.
It might not be exactly what your institution is thinking about implementing, but it's a good start.
Also, in addition to the USC FYE publications, there are a couple of useful books:
- Challenging and Supporting the First-Year Student: A Handbook for Improving the First Year of College
Achieving and Sustaining Institutional Excellence for the First Year of College
These resources will give you many different answers to all of your questions. The two books in particular are useful for providing case studies of FYEs at different kinds of institutions.
