解题是学习化学的重要过程,通过解题能巩固所学的知识;能加深对概念、规律的理解和深化,活化知识;能学习解题方法,发展思维,将知识转化为解决问题的能力。要达到此目的,多解题是必要的,但并非解题越多收益越大,除了解题数量外,做题方法和“质量”也是至关重要的因素。要掌握解题步骤,过好解题的“三关”,即审题关、分析关、解答关。 Problem-solving is an important process of learning chemistry. Through solving problems, you can consolidate what you have learned. You can deepen the understanding and deepening of concepts and laws, and activate knowledge. You can learn to solve problems, develop thinking, and turn knowledge into problem-solving skills. . To achieve this goal, multiple problem solving is necessary, but it is not that the more the problem is, the greater the benefits are. Except knowing the number of questions, the question method and “quality” are also crucial factors. To master the problem-solving steps and to solve the problem well, the “three levels”, that is, reviewing the problem, analyzing the problem, and answering the problem.
