For the Signing Math and Science products, TERC, in collaboration with Vcom3D, used the SigningAvatar accessibility software to develop interactive 3D sign language dictionaries and pictionaries of science and math terms and definitions to support access to standards-based content among elementary, middle-grade, and high school students who are deaf or hard of hearing and whose first language is sign. The dictionaries and pictionaries are now available in app form from work has been funded in part by grants from the National Science Foundation.

The SigningAvatar has also been incorporated into three units in the EnViSci Network series, published by Charlesbridge, to make them more accessible to students who are deaf and hard of hearing and whose first language is sign. To access the units, click here.
