对于初中生来说,形象思维要比抽象思维好一点.然而数学具有很强的系统性、逻辑性,如果紧把重点放在对文字和符号的表征上,很难做到对概念或定理的理解和应用.因此在初中数学的教学中,要注重显性化的教学,借助实物、图形和多媒体等多种教学手段,形象地将数学表象展示出来.利用一定的情境来激发学生的建模意识,在学生用心的观察下发现问题,激励学生采用思辨的方法大胆质疑,使学生能够发现其中的数学规律、数学思想.使学生由感性出发,逐步地实现理性的认
For junior high school students, the image thinking is better than the abstract thinking.Mathematics, however, has a strong systematic and logical nature, so it is very difficult to make a clear understanding of concepts or theorems if we focus on the characterization of words and symbols Understanding and application.Therefore, in the teaching of junior high school mathematics, we should pay attention to the explicit teaching, with the aid of many kinds of teaching methods, such as kind, figure and multimedia, vividly display the mathematical representation.Use certain situations to arouse the students’ modeling Consciousness, discovering problems under the observation of students’ motives, motivating students to boldly question using speculative methods to enable students to discover mathematical rules and mathematical thoughts among them, enabling students to realize rational recognition step by step from sensibility
