Only a few students signed up for American Sign Language classes at two high schools in Yakima, Washington when the classes were first offered five years ago. Now there are more than 20 times that number. Nearly 200 are taking one of the six ASL at Davis High Schoool and Eisenhower High School. Some of the classes have students wear earplugs once a week and only communicate in sign language. Extra credit can be earned by joining a monthly gathering of members of the deaf community for Deaf Chat Coffee.
