With this 3-year project, TERC and the Museum of Science (MoS) Boston are studying how family and school visitors integrate iPod Touch versions of the Signing Science Pictionary (SSP), Signing Science Dictionary (SSD), and Signing Math Dictionary (SMD) into their museum experience and the impact of dictionary use. This report focuses on family visitors. Each dictionary includes more than 700 standards-based science or mathematics terms. The SSP (funded in part by grants from the Shapiro Family Foundation and the U. S. Department of Education, Grant #H327A080040) is intended for children ages 5
