Ask any teacher and they would say workload is one of the biggest blockers to their professional development. Simply put, most teachers are time-poor and too busy to engage with educational research to improve their classroom instruction. One-pagers are ultra-concise, A4-sized summaries that share important ideas about good teaching. In this practical volume, Jamie Clark presents more than 55 evidence-informed one-pagers that help educators reflect on their practice, build pedagogical knowledge, and prompt professional conversations with colleagues.
