(一)根据大纲结合教材确定本课时教学目的与内容根据1956年6月教育部修订的“中学化学教学大纲”的指示,应该使学生获得工业上制造硝酸的生产知识,以发展他们对大规模化学生产的概念。我们本着大纲的这个精神,首先阅读了第二册第18页至第19页的课文内容,认为由氨制硝酸的各个反应过程已分别讲授过,故本课时讲解硝酸工业制法的反应过程只是连系旧有知识作综合性的说明而已。因学生已具有
(A) to determine the purpose and content of this lesson teaching purposes according to the outline combined with teaching materials According to the instructions of the “High School Chemistry Syllabus” revised by the Ministry of Education in June 1956, students should be allowed to acquire the industrial production of nitric acid production knowledge to develop their large-scale Concept of chemical production. In line with the spirit of the Outline, we first read the contents of the second volume of the text on pages 18 to 19, that the reaction process of nitric acid from ammonia has been taught separately, so this course will explain the reaction of nitric acid process Just connect the old knowledge for a comprehensive description of it. Because the students already have
