    Kiwi students have become the world’s first kids to be “taught” by a digital teacher named Will. Before you start imagining a human-like robot walking around the classroom. Will is just an avatar (化身) that appears on the student’s desktop, tablet or smartphone screen.

Auckland energy company Vector and AI company Soul Machines have worked together to model after the human brain and nervous system, allowing it to show human-like behavior. The digital teacher is now teaching primary school students about renewable energy.

Just like the humans it replaced, Will is able to instantly react to the students’ responses to the topic. He also picks up facial expressions, body language of the students. For instance, if a student smiles at Will, he smiles back. The two-way interaction(互动) not only helps capture(捕捉) the students’ attention, but also allows the program’s developers to monitor their performance, and make changes if needed.

Greg Cross, the Chief Business Officer of Soul Machines, says, “It’s well-documented that STEM teachers are in short supply in New Zealand schools. By using digital teachers, we are able to provide access to education to kids and communities that might not have access to real teachers.”

Greg believes that Will-like avatars could be a novel way to have the attention of the next generation. He says, “The program, in place since August 2018, has been a great success thus far. However, regardless of its popularity, Will is unlikely to replace human educators any time soon. For one thing, the avatar’s knowledge base is severely limited. For another, even the smartest digital avatars could never react to all the unexpected situations that educators have to deal with on a daily basis.”
