数学课题的揭示,也有一定的艺术,那么如何揭示呢?我的做法是:一、疑问揭示。在学生产生疑问时揭示。例如教学“循环小数”时,当教师先让学生计算1+3和70.7÷33两道题,当学生发现除不尽,产生疑惑时,教师抓住这一时机说:“今天我们要在除不尽的算式中来认识一种数——循环小数。然后开始这一节课的教学。这样学生的注意力就集中在所要研究的问题中。二、分步揭示。即在新授过程中逐步揭示,有些教学内容是随着讲授的逐步深入,逐渐完整的。
Mathematical topics revealed, there are certain art, so how to reveal it? My approach is: First, the question revealed. Revealed when students are in doubt. For example, when teaching “Repetitive Decimals,” when the teacher first asked the students to calculate the two questions of 1 + 3 and 70.7 ÷ 33, when the students found that there was no doubt that the teacher would seize this opportunity, he said: "Today we are going to divide Endless formulas to recognize a number - the cycle of decimals, and then start this lesson teaching so that students focus on the issue to be studied in. Second, step by step revealed that the new grant process Gradually revealed that some teaching content is gradually deepening with the teaching, gradually complete.
