This article from educational technology company EdSurge looks at how digital teaching portfolios can help instructors share and transform their teaching practices. Teaching portfolios “document evidence of teaching success as well as more informal descriptions of teaching mechanics.” Portfolios can also be a way for faculty to learn about the types of changes their colleagues are making in their teaching. The California State University system has a requirement that faculty who are awarded a grant for course revisions write a summary and reflection of their teaching. Through this requirement, a library of 200 teaching portfolios has been created. However, the article points out that portfolios are still not the norm for many professors and may require a “cultural change” to be fully adopted.
