Joint appointments and the professoriate: Two houses but no home?

Interdisciplinary work within higher education has increased significantly over past decades (Amey 2004; Creamer and Lattuca 2005). However, the professional implications of interdisciplinary research and instruction for the faculty members who engage in such academic work remain unclear. This study of science educators who hold appointments in two academic departments begins to address this empirical gap. The outcomes provide insight into the factors that influence the professional lives of these faculty members. The knowledge gained from the study will provide mentors, colleagues, and administrators insight into the challenges facing academics undertaking this work. Further, this research seeks to inform policy makers in regard to how tenure and promotion is determined for jointly appointed faculty in science education and other interdisciplinary fields.
