Components of Effective Use of Diagrams in Math Problem Solving.
Simon, Marty
Through individual interviews with remedial and precalculus university students, five characteristics of the student were identified that influence whether a diagram is used in solving a problem and whether its use is successful. The interviews also suggested a set of subskills that contribute to the overall ability to draw effective diagrams. These were then used in an experimental study to verify their impact on diagram drawing effectiveness. The list of subskills was translated into a series of external control suggestions for guiding the subject's work during an individual interview. Subjects who received these suggestions drew higher quality diagrams than did subjects in the control group. The enhanced quality was particularly apparent in the completeness of the diagrams.
