Teaching Research On Retarded Students' Study Of Geometric Figures And Proof With Textbooks Published In Jiangsu Education Press

The students with learning difficulties are the core issue for mathematics teaching during the recent 30 years. According to the 8th course reform and the"Five Strict"regulation in Jiangsu Province, the new course concept has been widely accepted by teachers. I participated in the Provincial Project,"The cause and solution for the increasing differences between students during the third stage of compulsory mathematics education". Considering the spiral ascending system of the soviet teaching material, the logic study is added before the graphics and proof study. Practical ability is emphasized in the graphic teaching with the decreasing text tasks. How do these changes affect the students with learning difficulties and how to avoid the adverse effects? This is the question which has not been figured out, and is the motivation of this paper which is of great value.Literature searching and compare method was utilized to make clear of the development of the graphic courses in China. The differences between current course, former course and foreign course have been analyzed. Observation, interview, investigation and teaching experiment were performed to figure out the cause of learning difficulties. The learning interest, motivation, self efficiency and self control of students with learning difficulties were investigated via questionnaire. Then the conclusions were obtained as follows. First of all, SLD (students with learning difficulties) can not go into further about the concepts and theorems. Second, SLD can not make relations between the obtained graphic knowledge. Third, SLD have difficulties in transforming the graphics, characters and symbols. Forth, SLD can not make correct logic. Fifth, SLD do not follow the regulation in answering questions. Sixth, SLD have troubles in finding the ideas for proof question,Seventh,SLD'graphic decomposition needs to be improved. Meanwhile, the experiment of advance the graphics and proof teaching was performed which brought great effect. Finally, a strategy was put forward in chapter 4. Based on the analyses above, SLD should be divided into several teams according to their characteristics. The dynamic atmosphere of the course is also very important for SLD.
