所谓发现法教学,就是教者对某些问题不先给学生明确的结论,而让学生自己从特殊、各别的问题出发,经过分析研究,发现这一问题的一般性规律,以得到应有的结论。我在运用发现法教学的过程中,感到这种方法确有不少好处。一、恰当运用发现法,有利于树立学生唯物主义观点。先看下面一个简单例子: 在进行组合数性质1 C_n~m=C_n~(n-m)的教学中,书本上一下子给出这一结论,然后用组合数的第二个常用公式进行证明。在实际教学时,我采取了以下步骤: 1、让学生用组合数公式计算C_9~7和C_(200)~(198)两道题。学生容易解出:
The so-called discovery of law teaching, that is, teachers do not give students a definite conclusion on certain issues, let the students themselves from special and individual problems, through analysis and research, found that the general law of the problem in order to get what Conclusion. In the process of using discovery teaching, I feel that this method does have many benefits. First, the proper use of discovery method is conducive to establishing a student materialist point of view. Consider the following simple example: In the teaching of combinatorial number property 1 C_n ~ m = C_n ~ (n-m), this conclusion is given in the book, and then proved by the second common formula of combination number. In the actual teaching, I took the following steps: 1, let students use combination number formula C_9 ~ 7 and C_ (200) ~ (198) two questions. Students easily solved:
