We need to invest more on the front end so we can be provocative and consider other possibilities. It costs money and takes time to come up with creative ideas. And if you're going to try something innovative, you have to bring along the community, the students, and the faculty. It takes strong leadership to move in new directions. The first thing students want in a school is a safe environment.
Safety needs to be there.
But if we stop there, in terms of design, we'll close schools down from the community. You can't solve security concerns by further isolating schools. It might be tempting to say, we're going to build locked little cells called classrooms and supervise them closely and not allow anybody to move freely in the hallways. We can get security that way, but we don't get much learning. If you start going in that direction, the end of the path is a prison.
