| To study quantitative chemical experiment is an important way for students to learn the scientific method.Chemistry quantitative experiment teaching can help to improve students’ scientific literacy.To some extent,the current teaching system of Chinese high school chemistry teaching underestimates the function of chemistry quantitative experiment teaching.Now domestic-related research is in its infancy,focusing on the function of chemistry quantitative experiment teaching and the methods of developing quantitative chemical concepts,and so on.In the Paper there is an important survey on the level of current chemistry quantitative experiment teaching in Chinese high schools,by the methods of literature review, questionnaires, interviews with teachers,case studies.This survey tries to make clear the principles of quantitative chemistry experiment teaching and.There is a teaching case study of the two representative quantitative chemical experiments in high school called "Acid-base titration" and "Heat of neutralization" of, hoping to improve the effectiveness of the chemistry quantitative experiment teaching in the future.The preface explains the reasons for the study.The fist part introduces the theories supporting the research.The second part is the definition of chemical quantitative experiments.The third part makes clear the principles of quantitative chemistry experiment teaching. The fourth partintroduces the survey on the level of current chemistry quantitative experiment teaching.The fifth part is the teaching case studies of "Acid-base titration" and "Heat of neutralization", trying to solve the problems of these two representative quantitative experimental teaching cases and develop appropriate teaching design.The last part is the conclusion of the study.High school chemistry teachers should pay enough emphasis on chemistry quantitative experimental teaching and the research on chemistry quantitative experiment teaching,improving the effectiveness of the chemistry quantitative experiment teaching in the future. |
