Many departments and universities are trying to spread the effective use of research-based instructional practices among their faculty, such as active learning and effective course assessments. One strategy that was used at the University of Colorado Boulder and the University of British Columbia was to provide direct, targeted help to faculty in the form of an educational expert who was also well-versed in the relevant subject matter. This Discipline-Based Education Specialist (DBES) partnered with faculty members to transform their courses, resulting in on-the-job learning and direct feedback to faculty members. This program (the Science Education Initiative)met with many successes – and challenges. The overall approach of the SEI is also adaptable to a wide range of initiatives aiming at helping faculty transform their teaching.
