一题多解在化学计算中是普遍现象。对同一个化学题目,从不同角度进行分析处理,可有多种不同的解法。将这些解法进行分析综合,比较对照,可以大大开拓学生的思维,培养学生的解题和应变能力,提高学生的解题技巧和解题的熟练程度、启发学生对待问题要多加思考,勤动脑筋,掌握知识的连贯性和规律性。然后,从一题的多解中选择其中一种最合理最简捷的方法。这样,学生就可以掌握知识大门的钥匙,在知识的
Many solutions to a problem are common in chemical calculations. There are many different solutions to the same chemistry problem from different perspectives. Analyzing and synthesizing these solutions, comparing and contrasting, can greatly expand student’s thinking, train students’ problem-solving and adapting abilities, improve students’ problem-solving skills and proficiency in problem-solving, and inspire students to think more when dealing with problems. To master the continuity and regularity of knowledge. Then, choose one of the most reasonable and simple methods from multiple solutions to a single question. In this way, students can master the key to knowledge, in the knowledge of
