在平时的教学过程中,我们常有这样的困惑:不仅讲了,而且讲了多遍,可是学生的解题能力就是得不到提高。也常听见学生这样埋怨:巩固题做了千万遍,数学成绩却迟迟得不到提高。如何改进教学策略,达到“减负增效”之目的,这应该引起我们的重视。诚然,出现上述情况涉及方方面面,但其中的例题教学值得我们反思。一、问题启发,难题化解古人云:“智者千虑,必有一失。”尽管课前对教案做了精心的设计,但是仍会存在一些课前没有考虑到的因素,课堂教
In the usual teaching process, we often have such confusion: not only talked about, but also said many times, but the ability of students to solve problems is not improved. Students are often told to complain about this: Consolidation has been done thousands of times, but the math performance has not been improved. How to improve the teaching strategy to achieve the purpose of “reducing the burden and increasing the efficiency” should deserve our attention. It is true that the above situations involve all aspects, but the teaching of examples among them deserves our reflection. First, the problem inspired, solve the problem Ancients said: “Despite the wise, there must be a loss. ” Although the pre-lesson plans to do a careful design, but there are still some factors not considered before class,
