充满活力的课堂,应该是在教师和学生投入相同时间和精力的条件下,能够获得较高的工作效益和学习效益的课堂。要想提高教学效益,必须向课堂45分钟要质量,要让课堂45分钟有限的教学时间发挥出最大的效益。这也是教师们一直努力的目标和方向。著名数学教育家波利亚曾说过:“思维是从问题开始的;问题是数学的心脏。”数学问题设计的质量直接影响整个教学的质量和效率。在此,结合教学实践就数学课如何进行“问题设计”谈一些体会。
A vibrant classroom should be a classroom where higher productivity and learning efficiency can be achieved given the same amount of time and energy invested by teachers and students. In order to improve teaching effectiveness, we must give the class 45 minutes to the quality, let the classroom 45 minutes limited teaching time to play the most effective. This is also the goal and direction that teachers have been working for. The well-known mathematics educator Polyana once said: “Thinking starts from the problem; the problem is the heart of mathematics.” The quality of mathematical problem design directly affects the quality and efficiency of the entire teaching. Here, with teaching practice on how to carry out the “problem design” talk about some experience.
