In the first two parts of this series, ("Teaching for Engagement: Part 1: Constructivist Principles, Case-Based Teaching, and Active Learning") and ("Teaching for Engagement: Part 2: Technology in the Service of Active Learning"), William J. Hunter sought to outline the theoretical rationale and research basis for such active learning methods as case-based teaching and problem learning, and then to describe ways in which contemporary technologies can facilitate teaching for active learning. Throughout, Hunter sought to keep a focus on practical questions and issues related to implementing active learning strategies in postsecondary classrooms. Nevertheless, there remains a lot to be said about designing and implementing active learning, especially for those whose prior teaching has been predominantly transmission-focused. In this, the third part, Hunter seeks to address practical questions regarding the design and implementation of teaching for active learning. Interested readers will find that the links provided in text and in the reference list will lead them not only to further detail about the ideas discussed in this series, but also to a wide variety of practical teaching resources.
