Alan Singer reports that ETS is adapting its teacher certification. It will replace students with avatars. Computer representations of real students.

Why? Pearson is doing it. That’s competition for you. A race to the bottom. Like network television.

There are many reasons to object to th idea of teaching avatars. One is that the essence of teaching is interaction. The teacher and students connecting, responding, reacting. Teaching avatars is like acting without a audience. It can be done, but the actors are at their best when they feel the audience response.
