【摘要】：21世纪,随着污染程度逐渐加深,环境问题日益严重,绿色化学思想应运而生。化学绿色化是社会可持续发展的根本,而化学实验绿色化则是化学绿色化的核心。因此高中化学教材实验绿色化具有一定的研究价值。相对于老教材而言,苏教版新课程的实验内容和编排形式有了较大的改变,替换了一些污染性较大的药品,减少了试剂的使用量,对某些实验也进行了相应的绿色化改进。然而,依旧存在很多缺陷,因此有必要对高中化学教材实验进行绿色化改进研究。本研究主要采用文献法、统计法、实验法、调查法、访谈法等研究方法,通过文献法查阅相关资料,梳理了相关概念、研究现状及较为前沿的实验方法；统计分析苏教版化学教材中的实验污染情况；调查研究师生的绿色化学意识和化学实验实施、改进情况；对部分教材实验进行绿色化改进,提出可行的改进方案。并且通过学生访谈,确定其方案的有效性。本研究主要分为以下五大部分内容：第一部分主要介绍了论文的研究背景、意义、问题、方法和思路。第二部分详细阐述了绿色化学的概念、原则和论文的研究现状。第三部分通过对苏教版《普通高中课程标准实验教科书·化学》实验内容进行归纳分析,统计出主要的污染物及其危害,并且分析了某些典型的污染性实验,归纳出化学实验绿色化的必要性。第四部分通过对一线教师和学生的问卷调查,初步得出目前高中化学实验绿色化的实施现状及问题成因分析。学校在实验室资源配备方面还不够完善,师生在实验实施方面也存在很多不足,最重要的是师生的化学实验绿色化意识方面也有待进一步提升。第五部分探讨了高中化学实验绿色化的实施策略,具体包括以下几点：(1)实验观念绿色化转变；(2)实验方案绿色化改进,包括实验设计绿色化、实验药品绿色化和实验设备微型化；(3)实验废物绿色化处理,包括回收利用和妥善处理；(4)实验模式绿色化开发。最后通过学生访谈,确定实施策略的有效性。
[Abstract]:In the 21 st century, with the deepening of pollution and environmental problems, green chemistry came into being. Chemical greening is the foundation of social sustainable development, and chemical experiment greening is the core of chemical greening. Therefore, high school chemistry teaching material experiment green has certain research value. Compared with the old textbooks, the new curriculum of the Soviet education version has a great change in the content and layout of the new curriculum, replacing some of the more polluting drugs, reducing the use of reagents, and improving the greening of some experiments. However, there are still many defects, so it is necessary to improve the experiment of chemistry teaching materials in senior high school. This research mainly uses literature method, statistics method, experimental method, investigation method, interview method and other research methods, through the literature method to consult the relevant materials, combing the relevant concepts, research status and more advanced experimental methods; This paper makes a statistical analysis of the experimental pollution in the chemistry textbooks of the Soviet Union Education Edition; investigates and studies the green chemistry consciousness of teachers and students and the implementation and improvement of chemical experiments; and puts forward some feasible improvement schemes for some teaching material experiments. And through student interviews, to determine the effectiveness of its program. This research is divided into the following five parts: the first part mainly introduces the research background, significance, problems, methods and ideas. In the second part, the concept, principle and research status of green chemistry are described in detail. In the third part, by summarizing and analyzing the contents of the experiment of "Chemistry of Common Senior Middle School Curriculum Standard Experimental textbook", the main pollutants and their harm are analyzed, and some typical pollution experiments are analyzed. The necessity of green chemistry experiment is concluded. In the fourth part, through the questionnaire survey of teachers and students, the author draws a preliminary conclusion that the current implementation of green chemistry experiment in senior high school and the causes of the problems. School in laboratory resources allocation is not perfect, teachers and students in the implementation of the experiment there are many deficiencies, the most important is that teachers and students of chemistry experiment green awareness also needs to be further improved. The fifth part discusses the implementation strategy of high school chemistry experiment greening, including the following several points: 1) the experiment idea is green, the experiment plan is green, including the experiment design green. Green treatment of laboratory waste, including recycling and proper disposal of laboratory waste. Finally, through student interviews, the effectiveness of the implementation strategy is determined.
