数学概念是数学知识之本、解题之源,学好它既是基础又是关键。可学习数学概念是一件枯燥的事,如何让学生理解数学概念,掌握数学原理,进行实际运用成为学习数学的难题,巧用电教媒体,能调动学生的多种感官,使学生在轻松愉快的情境中理解和掌握数学概念。一、妙用多媒体,将数学概念形象化。对于初中一年级的学生来来讲,思维以形象化为主,而数学概念却具有高度的抽象性,利用多媒体进行实际操作,形象演示不失为一个好的办法。
Mathematical concept is the basis of mathematical knowledge, the source of problem solving, learning it is both the foundation and the key. Can learn mathematics concept is a boring thing, how to make students understand the concept of mathematics, mathematical principles, the actual use of mathematics to become a difficult problem, clever use of audio-visual media, can mobilize the many senses of students so that students in a relaxed and happy Understand and master mathematical concepts in context. First, magical multimedia, visualization of mathematical concepts. For the first year of junior high school students come and go, thinking is the main visualization, but the mathematical concept has a high degree of abstraction, the use of multimedia for practical operation, the image presentation is a good way.
