Areas of Study


The Science of Learning Center on Visual Language and Visual Learning (VL2) has created and disseminated various research-based products to achieve their mission. Their mission is to bridge research and education to support Gallaudet University’s goal of public outreach.

VL2 products include:

  • Parent Information Packages
  • Storybook Apps
  • A Visual Communication Sign Language Checklist Assessment

Society benefits when products about language acquisition and development are shared with families, educators, and other interested people. But, it is important to withhold potentially harmful products from the marketplace.

VL2 has created a review and evaluation process to test products for value and efficacy. This is done through a Benefits and Risks Assessment Committee (BRAC).

A handbook serves as a guide for product developers, regardless of any past connection to VL2, and a resource to the BRAC organizer and members, VL2 staff, and other relevant individuals assisting with the review process. The goal is to hand it over to Gallaudet University for use with other departments and programs.
