中心对称图形属于几何类知识,在解题过程中,如果对其性质、类别不了解、不熟练,将会混淆解题步骤,降低题目准确率.传统的教学过程中,教师主要根据教育大纲、课本知识编写教案,并布置大量机械模仿练习题,没有加入相关动手实践过程,拉开了学生与知识的距离,使得学生学习数学知识处于“一知半解”的状态,既不能很好地辨析相关概念,也无法独立解决数学题目.因此在新课堂教学过程中,教师应带领学生进行多角度、多层次的数学实践活动,培养学生动手能力和独立思
Center symmetrical graphics belong to the knowledge of geometry, in the process of problem solving, if its nature, type do not understand, unskilled, will be confused to solve the problem steps to reduce the accuracy of the topic.Traditional teaching process, the teacher mainly in accordance with the syllabus, Textbook knowledge to prepare lesson plans, and layout of a large number of mechanical simulation exercises, did not join the relevant hands-on practice, opened the distance between students and knowledge, making students learn mathematical knowledge in a “half-baked” state, neither can distinguish good correlation Concept, can not solve the problem of mathematics independently.Therefore, in the process of new classroom teaching, teachers should lead students to carry out multi-angle, multi-level mathematics practice activities, develop students’ abilities and independent thinking
