Gary, Thanks for this post. One of the more successful career colleges requires that each new faculty member be observed in a classroon or lab environment at least once during the first three weeks of his or her first term and again at least once later in the term. Another college uses peer reviewers. They require new faculty members to sit in on classes taught by more experienced faculty members, then have the experienced faculty members sit in on the rookie's class. The peer review process tends to be less threatening to new folk than when an administrator sits in. I recommend a combination of both techniques.
