A Practical Study On The Cultivation Of "Chemical Value" In Middle School Cheruistry Teaching

With the significantly emphasis of the Party Central Committee on cultivating and practicing the core values of socialism,the cultivation of students' values has attracted more and more attention from educational researchers.As a natural discipline,chemistry is closely related to our daily life.With the development of social chemistry and chemical socialization,chemistry is becoming a central discipline to meet the development requirements of society.The release of the chemistry curriculum standards of senior high school(2017)points out the orientation of achieving the cultivation of chemistry value.Under the background of the socialist core values and the curriculum standard(2017),aiming at the neglect of cultivating students' chemistry value in middle school chemistry classroom teaching currently,combining with the existing theoretical research and practical research,this paper preliminarily determines the system of cultivating chemical value,states the application of the chemical value in the actual teaching process,analyzes the formation of the chemical value from the subject value and the social value,and provides some operable methods for cultivating the students' chemical value.Through literature analysis,the author understands the research status at home and abroad,clarifies the research background and research significance,determines the research ideas and research methods.According to the formation process of values,the theoretical basis for the cultivation of chemical values is determined.Through the questionnaire survey method and interview method,it can be obtained that the current status of middle school students and front-line teachers' understanding of the value of chemistry.Combined with this understanding and the requirement of chemistry value in the curriculum standard(2017),the knowledge of compulsory high school chemistry textbook 1(the people's education edition)can be summarized and analyzed in order to provide teachers with the vector of specific content of chemistry value,which can overcome teachers' insufficient understanding of the chemistry value.In addition,in response to the problem of teachers' lack of approaches and methods of cultivating chemistry value,the teaching principles of chemistry value cultivation are summarized(including the principles of full process,penetration,science,effectiveness and moderation).Meanwhile,the teaching strategies of chemistry value cultivation are generalized(including laying a good foundation of chemistry knowledge,conducting experimental exploration,and implementing educational concept named STEAM,applying chemistry history education and skillfully using modern education platform.On the basis of teaching principles and teaching strategies,a case development process that permeates the value of chemistry in middle school chemistry teaching is determined.According to the theoretical basis of the cultivation of chemical value,two designed teaching cases,"ionization of acid,alkali and salt in aqueous solution" and "ion reaction and its occurrence conditions",are practiced under the teaching principles and teaching strategies of the cultivation of chemical value,combined with the actual teaching situation of a middle school in Yinchuan.The chemistry value training system in middle school chemistry teaching is further improved by after-class interviews with teachers and students and teaching effectiveness survey based on the teacher evaluation,student evaluation and self-evaluation.The research shows that teachers have an important leading role in the teaching process of permeating chemistry value.Once teachers have a sufficient knowledge and teaching materials,they can better integrate the cultivation of chemistry value into the entire teaching process.The results of the practice show that students and teachers are full of interest in the class that permeates the value of chemistry,and accept the model of cultivating chemistry value.Therefore,the system of cultivating chemistry value in middle school chemistry teaching initially obtained in this study has practical value.
