数学起源于情境,情境是产生问题的沃土。新课标注重学生的发展,要求教学来源于学生的实际,要创设学生能独立自主学习的情境,引导他们通过实践、探索、交流,获得知识、拓展思维,学会学习。本文就如何创设问题情境谈谈自己的想法,以供同仁参考。一、创设问题情境的三原则(一)目标性原则在数学教学中,创设问题情境必须要有明确的目标,必须围绕教学的内容和任务来进行,要考虑到数学情境是否有价值。否则,再好的问题情景都是无用的,甚至是有害的。
Mathematics originated in the situation, the situation is fertile ground for problems. The new curriculum standard pays attention to the development of the students. It requires that the teaching come from the reality of the students. It is necessary to create situations in which the students can learn independently and guide them through practice, exploration, exchange, acquisition of knowledge, development of thinking and learning. This article on how to create a problem situation to talk about their own ideas for colleagues reference. First, the creation of the three principles of problem situations (A) the principle of the goal In mathematics teaching, creating a problem situation must have a clear goal, we must focus on the teaching content and tasks, taking into account the mathematical situation is valuable. Otherwise, even the best problem scenarios are useless, even harmful.
