A group of students taking sign language at a California high school pretended to be deaf for a day to better understand what it is like to face the obstacles that those with hearing loss deal with every day. They only spoke in sign language on March 20th at Valencia High School. Some students put signs around their neck saying "deaf' and others wore earplugs so that others would understand what they were doing. The idea was hatched by sign language teacher Phyllis Madden who led students in playing typical deaf games that require ASL or body language and gestures. Grades for the exercise were lowered if students were caught talking.
