At the beginning of each year, teachers have the daunting task of deciding which concepts and skills to teach their students. Many teachers feel the pressure to teach "the whole book". This pressure comes in multiple forms. There is ever-increasing pressure to perform well on state, national, and international exams. An added pressure is the mandate from the National Science Education Standards to include inquiry in the classroom (NRC 1996). While teachers may not be able to choose what standards get taught, teachers typically have the power to decide how to teach in their classrooms. As they adopt curriculum to be taught, they often have the false notion that every page must be read in order to cover all standards required by the state.
