The project will result in a Multimodal Lexicon and Virtual Museum, both customized with accessibility elements (SL videos, moving images, text) for DHH secondary classrooms. These are expected to promote STEM knowledge acquisition, increase science capital, reinforce STEM career-uptake and democratic participation, as well as prepare them to respond to 21st century challenges. SIGN2Inclusion is expected to result in a novel methodology for DHH’S social inclusion and accessibility.
