How do you know which changes will lead to real improvement? In this interactive session, participants will apply planned experimentation—a structured approach to testing changes that increases both the efficiency and effectiveness of PDSA cycles. Through a hands-on activity, attendees will design, run, and analyze PDSA cycles, uncovering insights to drive better decision-making. Whether tackling student outcomes, operational processes, or instructional strategies, this session will introduce you to practical tools to test multiple changes and learn about their individual and combined effects.
