Brett Fiedler and colleagues win 2022 Dr. Arthur I. Karshmer Award for Assistive Technology Research

A physics-education and inclusive-design specialist at the 精品SM在线影片 has been recognized for his work to help blind or visually impaired people learn geometry.

With colleagues at other institutions, Brett Fiedler, a researcher at 精品SM在线影片鈥檚 project, has won the Dr. Arthur I. Karshmer Award for Assistive Technology Research for their submission 鈥淎 Tangible Manipulative for Inclusive Quadrilateral Learning.鈥�

The prize is awarded annually to the authors of the best submission to the science/research journal track of the California State University Northridge (CSUN) Assistive Technology Conference, which describes itself as the premier event in the field of technology and people with disabilities.

Winners are recognized for their exemplary submission and excellence in research and the advancement of assistive technology. The submission is publicly available on the with later publication in the Journal on Technology and Persons with Disabilities in late spring 2022.

Fiedler and his colleagues designed and tested the efficacy of an interactive physical device that can help people explore four-sided shapes non-visually, by touch. The device is called a Tangible Manipulative for Quadrilaterals鈥攚hich the team also calls the Quad.

The device compares well to existing tools for non-visual shape identification used by the blind and visually impaired community, Fiedler said. 鈥淚t's the beginning of a line of collaborative work in building inclusive learning experiences that harness the affordances of physical manipulatives coupled to multimodal virtual learning tools and emphasize an oft-overlooked pathway to learning, body movement,鈥� he added.

Fiedler鈥檚 collaborators include Scott George Lambert of Saint Louis University, Chloe S. Hershenow of the University of Tulsa, Dor Abrahamson of the University of California Berkeley, and Jenna L. Gorlewicz of Saint Louis University. They will be recognized at the CSUN Assistive Technology Conference next week.

A YouTube video featuring Abrahamson shows the genesis of the Quad device, demonstrates how it works and acknowledges the contribution of each collaborator. See the video .

As the video鈥檚 narrator states, the quadrilateral device can be used by students regardless of how well they see, 鈥渨hether they have 20/20 vision, 20/50 or 20/200,鈥� adding that 鈥渋t鈥檚 the ultimate in inclusive learning.鈥�

In support of the collaboration, Fiedler helped design the Quad and interpret the findings of the studies with blind and visually impaired participants. He and team (led by PhET Director of Research and Accessibility Emily Moore) continue to work closely with their collaborators in developing the virtual display that will provide multimodal support (e.g., sounds, speech, vibrations, etc.) to the physical Quad device.

Fiedler earned his PhD in physical chemistry from 精品SM在线影片 in 2017 and spent several years as part of the JILA Physics Frontier Center-funded PISEC program, working with 精品SM在线影片 students and local K-12 students in informal science learning spaces.

Working now for the PhET Interactive Simulations project, Fiedler researches and designs new multimodal features for PhET simulations to provide all learners with access and enjoyable learning experiences with the sims.
