A chair of a search committee for English writes about what should be in the portfolio.
A reader should have the answers to these three basic questions after reading your teaching portfolio. Ideally, they’ll be addressed toward the beginning:
1.How long has this person been teaching?
2.How many (and which) courses has this person taught?
3.How many (and what kinds of) student populations has this person taught?
Then she goes on to give a list of materials that should be included.
