In this article, we present a revised version of the active learning classroom observation tool (ALCOT), designed in 2015, to support instructor reflection on instructional approaches applied within active learning classrooms. The design of active learning classrooms and teaching approaches within them have changed significantly since the initial development of the ALCOT. Inspired by these changes, we have decided to update the ALCOT to address the new developments in classroom designs and instruction. In addition to updates to the ALCOT, this article also lays out ways the new ALCOT can be used for additional avenues of faculty support. It also suggests how classroom observation can facilitate conversation among a variety of stakeholders that could contribute to broad institutional change regarding active learning and active learning classrooms.
