The Signing Science Picture Dictionary (SSP) is an illustrated, interactive 3D sign language dictionary with 730 science terms defined in both American Sign Language (ASL) and Signed English (SE).

The SSP is one in a series of fully animated, illustrated and interactive 3D signing dictionaries. The SSP is designed for grade K-3 students who are Deaf or Hard-of-Hearing and use American Sign Language (ASL) or Signed English (SE) in the classroom.

The SSP supports access to standards-based science content among lower grade elementary students and is a great resource for teachers and parents!

The SSP will link to definitions in our Signing Science Dictionary and Signing Math Dictionary which can be found on iTunes.

Our 3D character can be zoomed in or out and rotated to give you the best vantage point for every sign. YOU control the placement of the character – not us!

Use the controls to choose the character and sign language you prefer; view the illustration; speed up or slow down the signing; and send the character to his "home" or default position. The signing will automatically loop until you go back (using the "back" arrow in the top left corner), thereby exiting from the signing page.

Use the Quick Start Guide in the app to walk you through what the SSP has to offer. For a full description of how to use the SSP, go to www.signingapp.com.

ASL Dictionary from NTID: Modified for Younger Users

ASL Dictionary from NTID: Modified for Younger Users

Rochester Institute of Technology

This is a modification for younger users of the popular ASL Video Dictionary and Inflection Guide from National Technical Institute for the Deaf. It does NOT include the Socially Restricted and Substance Abuse signs that many parents and school officials view as inappropriate for children and teenagers.

The program shows 2,700 signs and 650 sentences that demonstrate how signs change, or “inflect”, to convey different meanings. For example, modifications in hand movements and facial expressions can change the sign for “help” to mean help me, help them, help for a long time, etc. “Afternoon” can change to mean all afternoon, late afternoon or every afternoon. The sentences also show the full range of ASL grammar.

There is an option to show signs grouped into 24 categories: Countries, Animals, Numbers, States, Money, etc. As a self-test, users also have an option to choose when they see the English sentences – simultaneously with the ASL sentences, or afterwards.
