For many teachers, integration of subjects like science and reading makes perfect sense; for others--including many school administrators--it does not. For these individuals, integration is an approach that takes away valuable time needed to ensure that specific learning goals are met in each discrete subject. By building on the common ground between the subjects, you can address learning goals in both subjects without compromising either subject. In addition, you can maximize efficiency within the school day. So, the next time faced with an administrator who advises, "We must focus all our efforts on our Language Arts program" or a colleague who confides, "I don't have time to teach science anymore," share the rationale for integration presented here. It is possible to teach both subjects--effectively--through integration.
