The Practice And Exploration Of Chemistry Teaching In Middle School About The Permeation Of The Subject Thought About Chemistry

In the long term chemistry teaching in middle school,where knowledge is the main purpose,there is no profound understanding of "what chemistry is " for some teachers.Also there is a lack of deep thinking about the educational value and educational function of the chemistry knowledge.There are even some middle school chemistry teachers who never think about this problem.Therefore,it is necessary to pay attention to and strengthen the work of the permeation of the subject thought about chemistry in chemistry teaching in middle school.This paper first summarizes the research status of the subject thought about chemistry at home and abroad by literature analysis.The case analysis method is used to analyze the guidance of "the primary teaching principles" to the chemistry teaching and the permeation of the subject thought about chemistry in chemistry teaching.Then,the general teaching process of chemistry teaching under the guidance of "the primary teaching principles" is put forward,and the corresponding chemistry teaching design case is developed according to this process.Finally,the effectiveness of the above teaching design process and the development case are preliminarily evaluated by questionnaire and interview.Through the development,implementation and effectiveness evaluation of the chemistry teaching design in this way,students' literacy in chemistry can be cultivated,and they can also get the maximum development in De-Zhi-Ti-Mei-Lao aspects.Around the above point of view,the thesis is discussed as follows:The first part is the introduction.This paper introduces the literature review and the significance of the research and so on.The second part is the theoretical support of the study.It involves the theory and value of the primary teaching principles,the definition of the subject thought about chemistry and value analysis.The third part is the investigation.Aiming at how the front line middle school chemistry teachers use the primary teaching principles to guide the chemistry teaching in middle school,and how to permeate the subject thought about chemistry into middle school chemistry teaching,the author makes a detailed analysis of the teaching design and the corresponding teaching video.The experience is summed up,and the existing problems are also clarified.The fourth part is the design of the teaching process and the development of the teaching case.We strive to build a teaching process about how to permeate the subject thought about chemistry into the middle school chemistry teaching,and develop case studies from the following aspects :the determination of the target of the permeation of the subject thought,the selection of knowledge carriers and the design of activities and so on.The fifth part is the investigation and evaluation of the teaching effect.Firstly,two classes of parallel classes were set up in the experimental group and the control group respectively;Secondly,in the experimental group's chemistry teaching,we adhere to the permeation of the subject thought about chemistry,which lasted for half a semester;Finally,at the end of the semester,a questionnaire survey and interview were conducted on the understanding and application of the subject thought about chemistry to the experimental group and the control group.It is concluded that the permeation of the subject thought about chemistry needs to be persisted for a long time.The sixth part is the conclusion and the prospect.The conclusion and improvement of the paper are summarized.
