Find the links to your institution &/or division’s mission statement, strategic plan, and any other pertinent documents. Take a look at what they say about what makes for good teaching and learning on your campus (whether bricks and mortar or online).
One important use of a TPS is to show how your teaching is aligned with the values of your institution. Many sources also suggest that adjuncts & grad students who are actively looking for work should be prepared to rewrite their TPSs to fit the priorities of each job posting. This does not mean reinventing yourself but rather highlighting aspects of your experience & pedagogical perspective which make you a good candidate for a particular position.
