Enhancing AVT while downplaying ASL for the Bi-Bi ; the purpose of Bi-Bi is to focus on ASL development.
Bi-Bi is to develop individual students prior ASL skills while enhancing their knowledge of Deaf Culture.
Ernest C Drury School in Milton, ON is the prime example of the Bi-Bi setting. Deaf children use ASL and they are fluent ASL signers; they learn Deaf Studies, ASL syntax and semantics. The older students learn linguistics and Deaf history issues.
Oh it is a fantastic school.
