More important than cost is whether reducing class size improves learning. Reducing class size is the mother's milk of educational reform.
Conventional wisdom assumes that smaller classes are the key to improved performance.
In fact, some legislators have introduced bills in the upcoming session proposing that class-size reduction be made part of the Florida Constitution. Like the bullet train initiative, reducing class size would probably pass a statewide referendum by a wide margin. And like the bullet train, it comes with a tremendous cost. But even more important than cost is the question of whether reducing class size is actually going to improve learning. Perhaps the problem is not the size of the class, but the disconnect between conventional teaching and 21st Century students.
