一、必须强化解题过程中的审题意识教师应在教学中善于发现和暴露学生不懂得审题,不善于审题造成的后果,加强审题意识的教育,要警钟常鸣,提醒学生注意审题,在未找到解题方法之前,就要审题不止.例1:一只空瓶质量为100克,装满水后质量为600克,装满某种液体质量为500克,求这种液体的密度.一些学生往往不加审题,生搬密度公式,进 First, we must strengthen the problem-solving awareness in the process of problem solving. Teachers should be good at discovering and exposing students in the teaching. They do not understand how to review problems. They are not good at the consequences of problem-solving. They must be alert to the problem, and remind students to pay attention to the problem. Before finding a solution to the problem, it is necessary to examine more questions. Example 1: An empty bottle has a mass of 100 grams, and when it is filled with water, it has a mass of 600 grams and is filled with some liquid with a mass of 500 grams. Find the density of this liquid. Students often do not examine questions, move density formulas into
