A Study On The Application Of Chemical History In Chemistry Teaching In Senior Middle School

Since the implementation of new curriculum reformed, improving the scientific literacy of students has been the ultimate goal of chemistry curriculum. In order to implement this ultimate goal, it must be necessary to make the scientific literacy more specific. The three dimensional goals of the new curriculum:knowledge and skills, process and methods, emotional attitudes and values reflect the aspects and dimensions of the students’scientific literacy development. The history of chemistry has recorded the chemical occurrence, development and its changeable rules. At the same time, the history of chemistry contains the important chemical knowledge, process and methods, scientific thoughts, scientific attitudes and the way of thinking and cultural connotation of the chemist. History of chemistry education that is good for promoting the development of the students’scientific literacy and reflects the value of the chemistry subject to cultivate all-round development of students is the breakthrough point of achieving this goal.This thesis consists of four parts.The first part is introduction. It’s related from putting forward questions, the definition of chemical history, the research status at home and abroad of the chemical history, the theoretical basis of chemical history, the thoughts and methods of research and the value and meaning of research. This part tells the importance and necessity of the chemical history in chemistry teaching since the new curriculum reformed, and presents the questions to solve about the content of the research. It mainly introduces the definition of the scientific history and chemical history, and it’s based on Constructivism Theory, Situational Learning Theory, New Curriculum Theory and Characteristic of Chemistry Discipline to comb the knowledge about the history of chemistry and the history of chemistry education.The second part is education function. This part mainly expounds on education function of chemical history in chemical teaching from two aspects of scientific literacy and humanistic quality.The third part is interview and questionnaire. The workload of this part is to interview teachers and make a questionnaire survey from students. After that, summarize and analyze the interview and questionnaire to know the truth on the chemical history at school.The fourth part is the principle of teaching design on the chemical history and analysis, summary of cases. This part provides the accordance for the teaching design. Besides, combine with the material of chemical history to design and summary different kinds of teaching cases about the properties of benzene, flame reaction, the properties of chlorine, alloy, the nature of the combustion and the development of the periodic table to help develop the history of chemistry teaching.The focus of this thesis:1. To study chemistry history teaching on interview and questionnaire investigation from two aspects of teachers and students. In view of the teachers’interviews, from the teachers’ understanding of chemistry history teaching, the use of chemical history and the discussion of chemistry history problems existing in application to study. In view of the student questionnaire survey, to study in particular from whether students interest in the history of chemistry teaching to whether the development of chemistry history teaching brings all aspects of the harvest to students.2.Design six kinds of the teaching cases from the properties of benzene, flame reaction, the properties of chlorine, alloy, the nature of the combustion and the development of the periodic table to reflect the diversity of chemistry history teaching fully and to help develop the history of chemistry teaching.
