Overviews and generalized examples of how to apply Universal Design in Instruction (UDI) with embedded strategies to diminish barriers for Persons with Disabilities have been shared during earlier Earth Educator Rendezvous sessions (2017 and 2018) and through a recent NAGT Professional Webinar (28 April 2021) to promote better design for equity and inclusion in various STEM learning spaces. This poster will include a synopsis of strategies for apparent and non apparent disabilities and focus on several introductory geosciences activities modified and mapped to UDI guidelines addressing engagement, representation and action – expression. This is to provide discipline-specific examples designed for: (1) access through recruiting interest and providing options for perception and physical action; (2) building skills to sustain and persist; and (3) internalizing through self-regulation, comprehension and executive function. UDI reaches a wide range of learners and, additionally, is best modeled for pre-service teacher candidates also enrolled in general core introductory courses.
