【摘要】：化学定量实验是学生学习科学方法的重要途径,开展化学定量实验教学有助于提高学生的科学素养。我国现行高中化学教学体系在一定程度上存在轻视定量实验教学的弊端。国内相关研究正处于起步阶段,注重定量实验教学的功能和学生化学定量观念的培养等方面的研究。论文通过文献研究、问卷调查、教师访谈、案例分析等方法对高中化学定量实验教学现状进行研究,尝试了解化学定量实验教学的原则、模式,着重选取了“酸碱中和滴定”和“中和热的测定”这两个具有代表性的高中化学定量实验教学案例作为研究对象,期望能提高今后定量教学的科学性和有效性。前言介绍选题缘由;第一部分是理论基础;第二部分是化学定量实验的概念界定;第三部分介绍定量实验教学的原则;第四部分调查目前高中化学定量实验教学的现状和存在的问题;第五部分是教学案例研究,选取“酸碱中和滴定”和“中和热的测定”两个教学案例研究,着重检测、分析并尝试解决这两个具有代表性的定量实验教学存在的问题,并设计开发相应的教学设计;最后是研究结论,作为高中化学一线教师应该提高对高中化定量实验教学的重视,展开定量实验教学研究,以丰富现行的高中化学定量实验教学体系,提高定量实验教学的科学性和有效性。
[Abstract]:Chemical quantitative experiment is an important way for students to learn scientific methods. Carrying out the teaching of chemical quantitative experiment is helpful to improve students' scientific accomplishment. The current high school chemistry teaching system in our country has the disadvantage of despising the quantitative experiment teaching to a certain extent. The related research in China is in its infancy, focusing on the function of quantitative experiment teaching and the cultivation of students' quantitative concept of chemistry. Through literature research, questionnaire investigation, teacher interview, case analysis and so on, this paper studies the present situation of chemistry quantitative experiment teaching in senior high school, and tries to understand the principle and mode of chemistry quantitative experiment teaching. In this paper, "acid-base neutralization titration" and "neutralization heat determination" are selected as two representative cases of chemical quantitative experiment teaching in senior high school, which are expected to improve the scientificity and effectiveness of quantitative teaching in the future. The first part is the theoretical basis; the second part is the definition of quantitative chemistry experiment; the third part introduces the principles of quantitative experiment teaching; The fourth part investigates the present situation and existing problems of chemistry quantitative experiment teaching in senior high school. The fifth part is the teaching case study, choosing "acid-base neutralization titration" and "neutralizing heat determination" two teaching case studies, focusing on the detection, analysis and attempt to solve the two representative quantitative experimental teaching problems, And design and develop the corresponding teaching design; Finally, the conclusion is that, as a senior high school chemistry teacher, we should pay more attention to the quantitative experimental teaching of high school chemistry and carry out quantitative experimental teaching research in order to enrich the current quantitative experimental teaching system of chemistry in senior high school. Improve the scientific nature and effectiveness of quantitative experiment teaching.
