A Case Study Of High School Chemistry Teaching Based On "Green Chemistry"

In this century"green chemistry"teaching occupies a very important position in the middle school chemistry teaching,in high school chemistry curriculum reform,the phase of quite a number of teachers and students are still not really understand the connotation and meaning of"green chemistry",and rarely in the teaching to explore the practical application of"green chemistry".In order to better promote the"green chemistry"teaching in the teaching activities,teachers in teaching students knowledge at the same time should also cultivate the students'environmental awareness,also should make the students more in-depth understanding of the meaning of"green chemistry".How to apply a teaching concept of"green chemistry"to the chemistry teaching is a very important problem,based on this,with the idea of"green chemistry"the new generation of teachers,through the development of new lesson example,develop"green chemistry"teaching approach,in this paper on the investigation of villages and towns middle school teachers and students based on selecting Sue version of high school chemistry compulsory 1the fourth project"the nature and function of SO₂ as an object of class case development to provide"green chemistry"teaching practice reference.This thesis is divided into the following six parts:The first part is the introduction.This paper introduces the background of the thesis and summarizes the literature of"green chemistry"education at home and abroad,and introduces the research methods and significance of this paper.The second part is the concept of"green chemistry".This paper briefly introduces the definition of"green chemistry"and the latest research direction of"green chemistry".The third part is the theoretical basis.Using Rogers'meaningful learning theory,recent development zone theory and maslow's hierarchy theory.The fourth part is about the investigation of the teaching of"green chemistry".Teachers and students are mainly interviewed and surveyed respectively,and the result is that the"green chemistry"of teachers and students is weak.The"green chemistry"teaching in the township high school has not been paid attention to according to the requirements of the curriculum standards,and there are still many places that are not in place,which require teachers and students to make continuous efforts to make progress together.the school did not organize learning activities such as:watch video ecosystem on the earth,and environmental programs sketch performance competition to guide and inspire students lead to students'vision is too narrow.The concept of"green chemistry"can not be applied to our daily life and teaching.According to the results of the investigation,the reasons for the results are analyzed and Suggestions and Suggestions are put forward.The fifth part is the development and teaching strategy of"green chemistry"teaching cases in high school,taking the nature and function of SO₂ as an example.In 2003,the ministry of education promulgated the"ordinary high school chemistry curriculum standard?experiment?"the discipline nature and chemical disciplines on the basis of the actual situation and the current social environment,to meaningful learning theory,the theory of the zone of proximal development,hierarchy of needs theory as the instruction,to Sue includes compulsorya fourth project"the nature and function of SO₂ in the development of teaching and teaching strategies.The sixth part is the periodical research results and future prospects.This paper makes a detailed summary of the various links of the paper,and analyzes the shortcomings of each link,and points out the direction of preparation for the follow-up study.
