本文以“角的分类和角的画法”为例,运用“跟着学生走”的教法,取得了很好的教学效果。一、备学,跟着发现走课前,让学生自己准备三个以上的发现和问题。第一,对于角,你已经知道了哪些相关的内容?举三个以上的例子。学生可能知道的内容:角有两条边,一个顶点;角的大小与边的长短无关,与角的两边叉开的大小有关;直角等于90度等。第二,在自学课本时,你发现了角的哪些新内容?举三个例子。学生可能发现的内容:钝角大于90度而小于180度,锐
In this paper, the classification of “angle and angle of painting” as an example, the use of “follow the students to go” teaching method, and achieved good teaching results. First, prepare for school, followed by the discovery before leaving for students to prepare their own more than three discoveries and problems. First, what do you know about corners? Take three or more examples. Students may know the content: the corner has two sides, a vertex; the size of the corner has nothing to do with the length of the side, and the angle on both sides of the fork size; right angle is equal to 90 degrees. Second, what new content do you find in the textbooks? Cite three examples. Students may find the contents: obtuse angle greater than 90 degrees and less than 180 degrees, sharp
