教数学,犹如教孩子走路,有时要先扶后放,有时要扶放结合。“扶”是指点,是教师施教,“放”是锻炼,是学生独立学习。在小学数学例题教学中,既注重扶,又敢于放,扶中有放,放中辅扶,能有效提高教学效益。一、造“墩”架桥,精讲巧引——扶教材中首次出现的例题对学生来说是陌生的,属知识的源头,是教师非讲不可的内容。教这类源头知识时,教师应立足于讲解和引导,也就是“扶”。如教学小学数学第十一册“百分数的意义”时,要精心设计问题,扶着学生自学:分母是100的分数叫做百分数吗?“8吨的1/100等于8%吨”这句话对吗?为
Teach mathematics, like teaching children to walk, and sometimes after the help Fu Fang, and sometimes to be put together. “Help ” is pointing, is the teacher teaching, “release ” is exercise, is the independent study of students. In primary school mathematics sample teaching, not only pay attention to help, but also dare to put, give support in place, placed in the auxiliary, can effectively improve teaching effectiveness. First, the construction of “pier ” bridge, concise Qiao cited - to help textbooks for the first time in the sample is unfamiliar to students, is the source of knowledge, is the teacher non-indispensable content. When teaching such source knowledge, teachers should base themselves on explaining and guiding, that is, “helping”. Such as the teaching of eleventh primary school mathematics, “the meaning of the percentage,” we should elaborate design problems, to help students learn: the denominator is the percentage of 100 is called the percentage? “” 1/100 of 8 tons is equal to 8% Is this sentence right?
