In this paper, we identify several approaches engineering faculty use to teach engineering topics. We report results from an exploratory study, consisting of 16 faculty interviews from five diverse institutions of higher education. We focus specifically on engineering faculty because the engineering faculty teaching culture is not well explored, even though there are many ongoing projects to reform engineering education. The results from this study contribute to efforts currently underway to improve teaching and learning in engineering education, as well as in higher education. Results from this study highlight the disciplinary nature of teaching in the engineering domain. Furthermore, our results can serve as a foundation to compare teaching approaches in other disciplines, or to potential changes in engineering teaching practices. (Contains 1 table and 1 note.)
