Diagrams, drawings, and pictures are prototypical representations of concepts. Students' drawings of their concepts of convergent plate boundaries provided an efficient mans of discovering some widely held misconceptions. Over 600 general education students' drawings of continent -continent convergent boundaries reveal two common misconceptions. Approximately one-third drew a continent-continent convergent boundary with concave slabs of continental crust as one might imagine two pieces of firm rubber pushed together on a rigid surface. Almost half drew mountains as one might imagine inverted ice cream cones on a rigid plank. One hundred eighty students were presented a drawing similar to the!first misconception and asked to comment on what was incorrect. Forty-nine percent of the students did not recognize the misconception. Students who did not recognize the incorrect representation had lower scores on the Purdue Visualization of Rotations Test than the students Who did. Misconceptions common to non-majors persist among upper class majors and beginning graduate students. Ten of 21 upper level geology majors and first year graduate students drew continent-continent convergent boundaries representing the same two prototype misconceptions that non-majors drew. Five out of 14 senior geology majors given a drawing representing a common misconception failed to recognize that the drawing was incorrect. [ABSTRACT FROM AUTHOR] |
