现行高中教材第三册(必修加选修)的第六单元第二节“性质实验方案的设计”是以乙二酸为例,讲述了性质实验方案设计的一般步骤和思路,教师在教学中通过对有机化合物的性质实验方案进行设计,向学生展示了在性质实验设计中应考虑的问题和方法,使学生初步了解对物质性质的认识规律。这为我们训练学生的综合能力和素质提供了一个很好的平台。如果教师能充分利用这一点的话,那这节课的价值无疑是无法估量的,学生必将终生受益。教材告诉我们,在进行性质实验方案的设计时,我们要充分了解物质的结构、性质、用途与制法之间的相互关系,要根据物质的结构特点来设计化学实验方案,探究或
The sixth unit of the current High School Textbook Book 3 (Compulsory and optional), Section 2 “Design of the Nature Experiment Program” uses oxalic acid as an example to describe the general steps and ideas for the design of the nature experiment program. The teacher passes through the teaching process. The experimental scheme for the nature of organic compounds was designed to show students the problems and methods that should be considered in the design of the nature of the experiment, so that the students could have a preliminary understanding of the laws governing the nature of matter. This provides us with a good platform for training students’ comprehensive ability and quality. If teachers can make full use of this, then the value of this lesson is undoubtedly incalculable, and students will benefit for the rest of their lives. The teaching materials tell us that when designing a nature experiment program, we must fully understand the relationship between the structure, nature, and use of materials, and the method of manufacture. We must design a chemical experiment program based on the structural characteristics of the material.
