The Handheld Signing Math & Science Dictionaries for Deaf
TERC and the Museum of Science (MoS) are studying the integration—into MoSís Take a Closer Look and Science in the Park exhibits—of iPod Touch versions of three successful innovations: the Signing Science Picture Dictionary (SSP) for grades K-4/children ages 5-8 who are deaf or hard of hearing and whose first language is sign; the Signing Science Dictionary (SSD) for a similar audience in grades 5-8/ages 9-12+; and the Signing Math Dictionary (SMD) for grades K-8/ages 5-12+. This 3-year project is employing a mixed-methods design to research how two audiences use the dictionaries to access science content during visits to the exhibits. One audience is family visitors ages 5-12+ who are deaf or hard of hearing; one audience is classroom visitors in grades K-8+ who are deaf or hard of hearing. The partners will also begin to establish the kinds of learning gains that are possible.
