数学公式是数学定理的符号语言表达式,在数学教学中处于十分突出的地位.由于符号语言的抽象性,如不注意教学的规律,常会效果不佳,或记忆失误,或盲目套用,更不能充分发挥公式的应有效用.在长期的教学实践中我摸索到以下几点体会,提出来供大家讨论.1 掌握公式的来龙去脉 Mathematical formulas are symbolic language expressions of mathematical theorems. They are in a prominent position in mathematics teaching. Due to the abstract nature of symbolic languages, if you do not pay attention to the laws of teaching, you often have poor results, or memory errors, or blindly apply them. The full use of the formula should be effective. In the long-term teaching practice, I have found out the following experiences and put it forward for discussion. 1 Mastering the ins and outs of the formula
