Based on his career-long experiences with Jere Brophy, Gene Hall uses this article to not only point out Brophy's pioneering contributions to research on teaching and learning, but also offers a few personal reflections about what it was like to work with Jere. In addition, Hall shares a story about how Brophy's works had a direct impact on Hall's opportunity to conduct some of the early research and initial verification of the Diagnostic Dimensions of the Concerns Based Adoption Model (CBAM) (Hall, Wallace & Dossett, 1973; Hall & Hord, 2015).
