Abstract | Examines 9th grade students' explanations of chemical reactions using two forms of open-ended essay questions, those providing students with key terms to be used as "anchors" on which to base their essay, and those that do not provide terms. Results indicate that more misunderstandings were elicited by the use of key terms as compared to the non-use of key terms. (Author/SOE) |
