Microteaching is a way of doing professional development for teachers wanting to incorporate new evidence-based and high-leverage practices into their instructional toolboxes. Given how much work is required in teaching and the limited time professionals have available, microteaching is an accessible process that supports instructional improvement by practicing evidence-based and high leverage strategies. Professionals, working with a small group of peers, engage a four-phase process that includes planning, enactment of a strategy, as well as individual and group reflection. Professionals use the opportunity to explore a teaching strategy that is responsive to student needs in the context of critical friends. Having an opportunity to try it out before introducing it in the classroom can be a valuable way to work out bugs, discover aspects that need development, and build a sense of efficacy. Microteaching is a way to support collegial growth by seeing into each other's classroom practice.
