“极端假设法”在化学解题中的应用

摘要

In chemistry teaching, there are often some problems because of inadequate conditions. So it is difficult to solve by the conventional method, the students do not know how to start with such problems. While extreme hypothesis method against its original intention, the inverse solution, will obviously not possible or likely but uncertain problem is assumed to be an extreme problem, so that idea became clear, clear, and quick results, greatly improving the solving speed, but also beneftcial to the cultivation of the students thought the flexibility and the ability to analyze the problem.%在化学教学中经常会碰到一些题目由于条件不足，很难按照常规方法解决，学生面对此类题目往往也无从下手。而极端假设法反其本意，正题反解，将明明不可能的或有可能但不明朗的问题假设为极端的问题，使思路变得明朗、清晰，从而速得结果，大大提高了解题的速度，也利于培养学生思维的灵活性和分析问题的能力。
