The National Science Education Standards (NSES) specifically addresses the frequency with which teachers should incorporate inquiry as a strategy in their science classrooms. “Although the Standards emphasize inquiry, this should not be interpreted as recommending a single approach to science teaching. Teachers should use different strategies to develop knowledge, understandings, and abilities described in the content standards. However, there is no one right way to instruct students. Rather, their instruction should be through a variety of strategies, selected based on current student understanding, their value in the continuum of learning, the goals of the lesson, and available resources.
