TERC and Vcom3Dare using the SigningAvatar® accessibility software to research, develop, and disseminate a Signing Earth Science Dictionary (SESD) of at least 750 standards-based Earth science terms for high school students who are deaf and hard of hearing and whose first language is sign. The partners are also evaluating the extent to which use of the SESD furthers understanding of standards-based Earth science content, command of the language of Earth science, and the ability to study Earth science independently. Development of the signed terms will result in the addition of new Earth science terms to the Avatar library for use in sign-enabling other materials. The SESD is intended to serve the ~36,000 grade 9-12 students who are deaf or hard of hearing and whose first language is sign, the majority of whom leave school reading at the fifth grade or below. It is also intended for teachers and interpreters that interact with members of this population and professionals working with Earth science education programs during field trips, internships etc. A Web-based version of the SESD is nearing completion and a mobile version is under development.
For our presentation, we will demonstrate the interactive features of the SigningAvatar® accessibility software that support the three principles of Universal Design for Learning (UL) and have been incorporated into the Web-based version of the innovation. We will also demonstrate the integration of these features into the iPod version. Preliminary results from national field-test data will provide insight into usability of the dictionary, students ability to use it independently, and the types of vocabulary and content-related learning gains that are possible.
