This topic brief is one in a series on personalized learning prepared for Conversations with Innovators, 2018. Active student responding (ASR) strategies promote meaningful engagement by all students and have been shown to increase student participation and decrease classroom disruption while also providing real-time formative assessment information to teachers. How can teachers increase active student responding? The procedures are actually quite simple, and can be implemented by new or veteran teachers, with pre-K to college students, across all subject matter domains, in urban, suburban, rural, and even online settings. No special materials or tools are needed (digital technology options are available but not required), and instructional planning does not require much more time or expertise than usual. This brief discusses the use of the following strategies in active student responding: (1) choral responding; (2) response cards; (3) guided notes; and (4) additional strategies.
