《九年制义务教育初中数学课程标准》规定,初中几何将逻辑性与直观性相结合,通过各种图形的概念、性质、作(画)图及运算方法的教学,发展学生的逻辑思维能力、空间观念和运算能力,并使他们初步获得研究几何图形的基本方法.初一学生初学平面几何,概念是否掌握好,是学习好平面几何课的关键,教学中应引起足够的重视.一、从直观形象思维到抽象创造思维在几何概念课的教学中,为了使学生建立清楚的概念,明确概念的内涵,掌握概念所反映的事物的一切本质属性的总和,教学时必须十分注意一些近似概念的异同,采取直观形象思维到抽象逻辑思维的有效教学手段,使学生既明确概念的内 “Nine-year compulsory education in junior high school mathematics curriculum standards” stipulates that junior high school geometry will be logical and intuitive combination of various graphics through the concept of nature, making (drawing) and computing methods of teaching and development of students’ logical thinking ability , The concept of space and computing power, and enable them to get the basic method of preliminary study of geometry.First of the students beginner plane geometry, the concept of good grasp of plane geometry is the key to learning, teaching should be given enough attention. From the visual image thinking to the abstract creation thinking In the teaching of the geometry concept class, in order to make the student to establish the clear concept, to clarify the connotation of the concept and grasp all the essential attributes of the things reflected by the concept, the teaching must pay close attention to some approximate concepts The similarities and differences, to take an intuitive visual thinking thinking to the effective teaching of logical thinking so that students not only clear the concept of
