"Can robots help teachers improve classroom learning?... Consider the work of Cynthia Breazeal... who leads the Personal Robots group. The group is conducting randomized control trials of the use of an AI-powered, teddy bear-sized and -looking robot named Tega in Boston-area schools... to improve the language and literacy skills of 5- and 6-year-olds. Researchers are tracking gains in the youngsters’ vocabulary and oral language development to determine how the use of human teachers and artificially intelligent robots together in classrooms compares with instruction without robots. “We’re starting to see some exciting and significant learning gains,” Breazeal said. “I am very encouraged.” But she conceded that a longer, bigger study is the next step... “We see a social-emotional benefit across age groups,” she said... If students started feeling much more comfortable interacting with robots... they might jeopardize their willingness and ability to have meaningful conversations or relationships with other people... Breazeal recognizes those downsides. “We need to be thinking more deeply around ethics,” she said, “particularly with AI with children.”"
