One argument often made by state officials discussing this reality is that teachers don't need to have a say in the curriculum because they can use their professional expertise and creativity when they plan how to teach the curriculum in their classrooms. These policy makers fail to understand that the curriculum, if rigidly enforced, has significant impact on how teachers teach. For example, teachers working under a highly prescribed curriculum with long lists of required objectives will approach instruction quite differently than teachers with a webbed curriculum that they have designed themselves. In short, what gets taught (curriculum) has a strong impact on how it gets taught(instruction).
