Wow – if only more speech therapists could see this…more administrators…if they could get statistics in their hands that bear out this truth – couldn’t it change the lives of so many deaf children? I would love to see this information passed on to those in charge of education in my state, by professionals whose words would be listened to!
Yes I wish more people would follow this. It is so important. ASL is a beautiful language and the deaf culture is so important.
