Many classes still take the form of traditional lectures, often with large groups that can make active learning a challenge. I will describe some simple techniques on how to make lectures more interactive, focussing on how to use Poll Everywhere to gather real-time student feedback on their own learning, using the ‘Muddiest Point’ metacognitive approach. Running these interactive polls over several lectures creates a classroom dialogue around topics that are interesting or challenging, even in a large cohort in which students are otherwise intimidated from asking questions. Additionally, it can be used to feed forward to later lectures, and ask students questions which test their prior learning. I will also describe the use of Padlet to set clinical case studies for students and provide feedback to stimulate class discussion.
