Due to success at adapting and implementing team-based learning (TBL) for use in sophomore-level electric circuit theory courses, an initiative is underway to encourage other faculty to use TBL in their courses, and instruct them in how to do so. The purpose of this work-in-progress paper is to describe an online training course that is being developed to assist engineering instructors in learning to use TBL as well as other forms of group-based student-centered active learning in the classroom. Currently, the course consists of five units, each of which culminates in a quiz that must be taken successfully before moving on to the next section. The content sections consist of Powerpoint slides plus detailed instructor commentary for further explanation. Also included are selected illustrative video clips taken during an exemplary classroom session.
