<p>I don’t necessarily think classes such as Cal I need to be taught be tenured facutly-certainly they can be excellent teachers but really one’s teaching style seems more important. Of course, in upper level courses I’d rather have someone who’s an expert in the field-for instance I’d rather have the Doctoral Candidate in Latin American history teach the class in the field as opposed to the colonial US historian. At some smaller liberal arts schools, professors that are tenure track could teach outside their field of expertise to fill all the courses.</p>
