中学生数学理解障碍及教学对策的探究

The Study of Mathematical Understanding Obstacles and Teaching Methods in Middle School Students

数学理解障碍是数学学习中不容忽视的一种障碍.从数学认知、教育心理学等层面来讲,中学生的数学理解障碍有认知型障碍,表象型障碍,联系型障碍,语言型障碍;克服这些障碍相应的教学对策有:帮助学生生成正确的数学表象;利用实物、模型等,增强学生对知识的感性认识;利用多媒体进行辅助教学;注重数学交流;加强学生对数学知识的自主探究与实际应用等来加深理解.

Mathematical understanding obstacles can not be ignored in learning mathematics. From the viewpoint of cognition of mathematics, education and psychology, middle school students has such understanding obstacles as cognition, idea, contact, language. In order to help students deal with the hindrance, we put forward appropriate teaching methods： help the students with their acquiring the right mathematical idea; strengthen their perceptual knowledge with the help of objects and models; to make a good use of multimedia assistant; highlight mathematical communication; deepen their understanding through reinforcing their independent exploration and application.
