Exploration On The Application Of "STSE Educational Concept + Learning Guidance Plan Teaching" Model In Middle School Chemistry Teaching

From the current proposition trend of college entrance examination chemistry,we no longer only pay attention to students’ simple understanding of knowledge,but pay more and more attention to whether students can connect knowledge with daily life.This is also in line with the quality education advocated in recent years and the focus on cultivating students’ core quality of chemistry.Under this background,this study analyzes the research status of STSE education and guided learning case teaching through literature query,combines STSE education concept with guided learning case teaching,puts forward the mode of "STSE education concept+ guided learning case teaching",determines the research purpose,significance,content,ideas and methods,defines the concept,and determines the theoretical basis.Then collect relevant data through questionnaires and interviews,put forward corresponding teaching strategies,carry out the teaching design and learning guidance plan design of the mode of "STSE educational concept + learning guidance plan teaching",reflect on the teaching practice,further optimize the teaching design,carry out teaching practice again,analyze the teaching implementation effect,draw specific conclusions and put forward feasible suggestions.Specifically,the research mainly includes the following parts: the first part puts forward the purpose and significance of the research,research contents,methods and ideas by studying the proposition trend of the new college entrance examination and the development trend of quality education,chemical core literacy,science education and humanistic education.The second part is to understand what STSE education and learning guidance case teaching are and their advantages,the research on STSE education and learning guidance case teaching at home and abroad,sort out the research status at home and abroad,and get the innovation of this research.Define the concept of "STSE education concept + learning guidance plan teaching" mode,and determine the relevant theoretical basis of this study.The third part is based on the questionnaire and interview carried out before the design of teaching design and learning guidance plan,and analyzes the results.Based on the previous work,the fourth part puts forward the teaching strategies,teaching design ideas and learning guidance plan teaching ideas,and designs the teaching design and learning guidance plan design of the mode of "STSE education concept + learning guidance plan teaching",in which the three topics of "alcohol","aldehyde" and "carboxylic acid" in "oxygenated derivatives of hydrocarbons" are selected as examples,and their teaching reflection and teaching implementation effect evaluation are carried out.Through teaching practice and teaching implementation effect evaluation,it shows that the mode of "STSE educational concept + learning guidance plan teaching" has a good teaching implementation effect for teaching.The fifth part is the overall conclusion of the research,and the prospect of the model of "STSE educational concept + learning guidance case teaching".The middle school chemistry teaching research of the mode of "STSE education concept+ guided learning case teaching" proposed in this paper draws lessons from many curriculum reform concepts,excellent previous theoretical and practical research,combined with the current proposition trend of college entrance examination chemistry,as well as the trend of quality education and paying attention to cultivating students’ chemical core literacy in recent years,creates teaching situations with STSE materials and guided learning case teaching as the carrier,Creatively design and put forward the "STSE education concept + learning guidance case teaching" mode,so as to strengthen the connection between students’ scientific knowledge and life practice,strengthen the cultivation of students’ chemical core literacy,and improve students’ learning efficiency.Innovation:1.Taking into account the factors of the times,such as college entrance examination proposition,scientific literacy,humanistic literacy and chemical core literacy,this paper puts forward the model of "STSE education concept + learning guidance case teaching" to explore the application of middle school chemistry teaching.2.The relevant teaching design is based on the results of questionnaires and interviews.Through reflection on teaching practice,the teaching design and guidance plan are further optimized,and finally the teaching design and guidance plan of "alcohol","aldehyde" and "carboxylic acid" are formed.3.This paper puts forward the corresponding scale for the evaluation of the teaching implementation effect of the mode of "STSE educational concept + learning guidance plan teaching",which is convenient for teachers to evaluate their teaching effect,and then analyzes the answers of some students after the learning guidance plan class.
