《全日制十年制学校中学化学教学大纲(试行草案)》对化学计算的教学明确地指出:“进行化学计算能使学生从量的方面来理解物质及其变化规律,并获得化学计算的基本技能。在教学中教师要有目的、有计划地布置适当数量、富有启发性的综合题,并加强解题指导,……”加强这方面的训练,对提高化学教学质量有很大帮助。通过解答综合题,可以帮助学生巩固和加深理解化学原理,从而更熟练地解答比较复杂的习题。为此,这里介绍一种比较简捷的列式解法来更好地培养学生解答综合题的技能技巧。
The “Full-time 10-year school chemistry syllabus for secondary schools (draft)” explicitly states that the teaching of chemistry calculations: “Chemical calculations enable students to understand the laws of matter and its changes from the quantitative aspect, and to obtain the basics of chemical calculations. Skills: In teaching, teachers should purposefully and systematically arrange appropriate numbers of inspiring comprehensive questions and strengthen the guidance of problem solving....” Strengthening the training in this area will greatly help improve the quality of chemistry teaching. By answering comprehensive questions, you can help students consolidate and deepen their understanding of chemical principles so that they can more skillfully answer more complex problems. To this end, here is a simpler columnar solution to better develop students’ skills and skills in answering comprehensive questions.
