TERC and Vcom3D are using the SigningAvatar® assistive technology to create an illustrated interactive 3D dictionary of signed mathematics terms for children in grades K-4 who are deaf or hard of hearing. They will evaluate it for usability and feasibility, and add to the Avatar lexicon of signs for mathematics terms for use in developing other mathematics materials. This project builds on research that led to the development of the Signing Science Dictionary (SSD)—a dictionary of ~1,300 science terms and definitions for grades 4-8—and the Signing Math Dictionary for grades 5-8. The SSD was funded in part by grants from NEC Foundation of America, the National Science Foundation (HRD-0533057), and the U.S. Department of Education (H327A060026). The SMD was funded in part by a grant from the National Science Foundation (HRD-0833969).
