I am a product of Detroit Public Schools. When I graduated, each person was supposed to do at least one year of a 'foreign language'. Not sure of a better term to be inclusive of ASL, but wouldn't it be grand if a year of ASL was offered?
In High School, at least, all the kids could have a chance to learn the Alphabet, Colors, Numbers and some simple greetings.
I have niblings (nieces and nephews) and I am sure to teach them all the IMPORTANT stuff: cookie, ice cream, bathroom, mother, father, eat, hungry, sleepy, and the alphabet, too. All before they start school. I think that would be great for ALL kids.
I believe that exposure to ASL serves several purposes: It helps people to express themselves, being exposes to ASL could help them to see the D/HoH Community as not so 'foreign', and it could get more kids to learn to become fluent so that there is increased communication.
Please try to get ASL into your schools. Preferably before grade 3, but as a catch-all, in High School.
