Co-Designing Accessible Science Education Simulations with Blind and Visually-Impaired Teens

Design thinking is an approach to educational curriculum that builds empathy, encourages ideation, and fosters active problem solving through hands-on design projects. Embedding participatory “co-design” into design thinking curriculum offers students agency in finding solutions to real-world design challenges, which may support personal empowerment. An opportunity to explore this prospect arose in the design of sounds for an accessible interactive science-education simulation in the PhET Project. Over the course of three weeks, PhET researchers engaged blind and visually-impaired high-school students in a design thinking curriculum that included the co-design of sounds and auditory interactions for the Balloons and Static Electricity (BASE) sim. By the end of the curriculum, students had iterated through all aspects of design thinking and performed a quantitative evaluation of multiple sound prototypes. Furthermore, the group’s mean self-efficacy rating had increased. We reflect on our curriculum and the choices we made that helped enable the students to become authentic partners in sound design.
