A common misconception about curriculum mapping is that teachers and administrators just need to come together once or twice a year to rewrite the curriculum, pick the resources they will use, and then they’re done. The problem with this approach is that the written curriculum will quickly fall into disuse, never to be revisited. By contrast, effective curriculum mapping entails recording what teachers are actually teaching, whether it’s aligned with standards, how it is impacting student achievement, and determining what needs to be updated and improved.
