You should ask what type of curriculum that the preschool uses. There are many different kinds, then ask why they use that particular curriculum. My favorite out of the ones that I have reviewed has been High/Scope.

I like it because it is about teaching children through active learning. Kids are more likely to remember something that they learned through playing.

In the High/Scope Philosophy it states: “Young children build or “construct” their knowledge of the world. That means learning is not simply a process of adults giving information to children. Rather, children participate actively in the leaning process. They discoverer things through direct experience with people, objects, events, and ideas.”
