博士 === 國立臺灣師範大學 === 工業科技教育學系 === 96 === This study aimed to investigate the representative types of solid geometric figure drawings by teenagers of 6th, 8th and 10th graders and the factors correlated. There were 131 6th, 154 8th and 210 10th graders asked to draw cubes, regular tetrahedrons, regular octahedrons, and regular dodecahedrons in two circumstances. In the first circumstance, the subjects were given verbal instructions and a real model was shown for 5 seconds at the beginning of each test session. In the second circumstance, the model was provided in front of the subjects during the whole session. The subjects' drawings were graded and classified into different types. The grades were then analyzed against the subjects’ grades in Math, Chinese, the General Aptitude Test Battery (GATB) and the Motor Accuracy-Revised tests. Results reveal that the error rate of 6th graders is significantly higher and their grades are significantly lower than those of 8th and 10th graders. It shows that performances of students beyond 8th grade are stable. The results support Lowenfeld’s theory that after reaching the period of decision/crisis the drawing ability of adolescents ceases to develop naturally. The more complicated a solid geometric figure is, the higher the error rate is and the lower the grades are. Besides, grades of female subjects are significantly higher than those of male subjects. Furthermore, the subjects’ performances were improved in the second circumstance under which more cues were given. It is also found that drawing ability is correlated significantly with abilities in spatial relations, picture matching, instrument recognition, hand-eye coordination, angle drawing, vertical and horizontal lines drawing, and grades in Math and Chinese. Hand-eye coordination, spatial relations, angle drawing, and picture matching are argued to be better predictors for drawing ability.
