This study aims to investigate the effect by using of 3D（Tree-Dimension）software aid on the learning effectiveness for the fourth-grade elementary school children’s moon phase concept. The authors adopted a pretest-posttest research design with 2 equivalent groups. The subjects were comprised of 55 the fourth graders from an elementary school in Pingtung County, divided into an experimental group with 28 subjects and a control group with 27 subjects. Both groups attended nine 40-min lessons with of the Engagement, Exploration, Explanation, Extension, and Evaluation（5E）learning cycle instruction over a month. Subjects in the experimental group received the moon phase 3D software aid instruction, and subjects in the control group received traditional aids（poster images and models）lecture instruction. This study also collected the qualitative data by semi-structured interview with some students. The results of the study showed that the experimental group performed better than the control group in the total score of the moon phase concept test. Furthermore, the qualitative interview results showed that some subjects still have alternative concepts after using aid instruction. The main reason is that the concept of children’s orientation has not yet established completely. The research suggests that the teaching design can be improved to enhance the learning effect. |
