化学计算永远面临着思维求异和解法求优的问题。高考化学计算题(特别是计算型选择题)往往隐含着巧解巧算思路。在高考复习中,教师不仅要指导学生形成正确的解题思路,掌握解题的一般规律和方法,而且还要引导和激发学生突破常规的意识。若能引导学生摆脱习惯思维束缚,全方位,多角度思考问题,势必能增智生巧、 Chemical calculations are always faced with the problem of thinking and seeking solutions to differences. Chemical calculation questions (especially computational multiple-choice questions) in college entrance examinations often imply clever solutions. In the review of college entrance examinations, teachers must not only guide students to form the correct problem-solving ideas, master the general laws and methods of solving problems, but also guide and stimulate students to break through the conventional consciousness. If we can guide students to get rid of the shackles of customary thinking and think about problems in all directions and from multiple angles, they will certainly be able to increase their wisdom and improve their success.
