Is This a Mathematics Class?

摘要

Let us tiptoe down the hall and peek into a "classroom of the future" that is here today. This doesn't look like a mathematics class. All the desks are turned to face each other. The students are writing with felt-tipped markers on butcher paper. They are looking at one another's graphing calculators. The teacher is nowhere to be seen. Oh, there he is, sitting down with one of the groups. A student is explaining something to him. One student has walked away from her group to confer with another group. She never asked for permission.
