Essential Feature 5: Learners Communicate and Justify
Their Proposed Explanations.
Scientists communicate their explanations in such a way that their results can
be reproduced. This requires clear articulation of the question, procedures,
evidence, and proposed explanation, as well as a review of alternative expla-
nations. It provides for further skeptical review and the opportunity for other
scientists to use the explanation in working on new questions.
Having students share their explanations provides other students and
teachers the opportunity to ask questions, examine evidence, identify faulty
reasoning, point out statements that go beyond the evidence, and suggest
alternative explanations for the same observations. Sharing explanations can
bring into question or fortify the connections students have made among the
evidence, existing scientific knowledge, and their proposed explanations. As
a result, students can resolve contradictions and solidify an empirically based
argument.
Variations of Inquiry in Science Classrooms
One of the unfortunate misconceptions about teaching science as inquiry is that
all inquiry must originate with a student’s question. In the extreme, this position
does not allow for other origins for questions, such as the science teacher asking
a question, conducting a demonstration, or engaging students in an activity.
Inquiry and the National Science Education Standards (NRC 2000) presents a view
of classroom inquiry that is not this either/or position. Rather, the view is one of
a continuum and variations that may range from less to more self-direction by
students and more to less direction by teachers, materials, or other sources. Table
4.2 (p. 86) uses the essential features of inquiry and presents this continuum.
