If you are currently looking for a teaching job at a college or university, then having a teaching portfolio introduced by a well-written statement of teaching philosophy. The statement of teaching philosophy tells a prospective employer (or, later on, a tenure and promotion committee) who you are as a teacher and researcher. And writing the statement of teaching philosophy can help you not only to define who you are as a teacher, but it can also help you refine what you do in the classroom in order to be the best teacher you can be.
