| Summary: | 碩士 === 國立嘉義大學 === 國民教育研究所 === 92 === This study aimed at utilizing the sixth-grade teaching module of three-dimension geometry to implement the remedial teaching for four students, and at evaluating the effectiveness. Four 6th graders’ solving tendency for three-dimension geometry was analyzed first and then the module was implemented for remedial teaching. The improvements of target students’ concept on three-dimension geometry were studied through the process. This research ended up with two findings. First, before the remedial teaching , 6th graders’ solving tendency with such concept as “recognition among solids”, “comprehension on elements”, “nets”, “penetrating pictures”, and “relationship between parallel and vertical” were unsatisfactory. Second, after the remedial teaching, except being less effective in improving one student’s recognition for tilting solids and understanding of dash lines in penetrating pictures, and in improving the other student’s learning of “pyramids are equilateral” and “parallel and vertical edges of solids”, it was more effective in improving four student’s other concept on three-dimension geometry.
