We've all had the experience of teaching our students new content, watching them learn it, and then watching them forget it as time goes by. How can we help students fend off forgetting? Recent cognitive psychology research suggests a strategy called retrieval practice is a teacher's best option to support student remembering of content in the long-term. Based on conversations with learning scientists, Cult of Pedagogy's Jennifer Gonzalez (2017) has called retrieval practice "the most powerful learning strategy you're not using." This session will explain how to use it through concrete examples and offer specific tips for using it in ways that don't take much prep time but have a big impact on learning. If you're tired of feeling disappointed by how much students have forgotten by the end of the year and don't want to keep spending so much time on crammed review in May, this session's for you.
