This session, Universally Designed Puberty Instruction, focuses on a collaboration between the Adolescent Resource Center (ARC) Program at Children & Families First and the University of Delaware’s College of Education and Human Development. This joint effort is to conduct a research project focusing on the effects of a universally designed fifth-grade puberty unit on student outcomes. The collaboration aims to identify barriers within the existing unit on puberty developed and delivered by ARC instructors. Through a series of lesson design sessions the researcher, instructor, and UDL practitioner discussed and analyzed the instructional delivery, methods, and materials used within the unit. Barriers to learning were identified and eliminated through the UDL framework. Participants will learn about the collaborative process, how barriers were eliminated, and lessons learned through this collaborative process.
