It was 11 a.m. when science class started on Monday, August 17. A group of about 15 students was doing what students usually do before class starts: happily chatting about what they did on the weekend. There was nothing out of the usual until you looked closer and noticed the students ranged from a very young age to their senior years, and everyone was taking part in the class from their own home through a videoconferencing app. “It’s good that there are adults, teenagers, and children,” said Gail Berman, a 64-year-old student. This heterogeneous group is connected by a condition that is common to all of them: everyone has autism spectrum disorder.
