Research And Practice Of Chemistry Situational Teaching In Senior High School From The Perspective Of Core Accomplishment Of Chemistry Discipline

Developing quality education and cultivating innovative talents are the requirements of the new era.The education of senior high school undertakes the important task of carrying out quality education and training talents,and is the key stage of the promotion of innovative consciousness and innovative thinking and comprehensive quality.High school chemistry teaching undertakes the important mission of developing students' chemistry core accomplishment.The "Chemistry Curriculum Standards for Senior High Schools" issued in2017 provides a measurement standard for the implementation of the core literacy of chemistry,and at the same time puts forward specific requirements and suggestions for teaching activities:we should pay attention to the creation of teaching situations,promote the improvement of students' thinking and ability,and realize the development of literacy.It can be seen that the indepth integration of rich contextual materials in accordance with The Times,society,life and other connotations into teaching practice can help stimulate students' interest in learning,help students establish connections between knowledge,accomplishment and emotion,and help them exercise creative thinking and implement the core accomplishment of chemistry.By sorting out the research progress of domestic and foreign scholars on situational teaching and core literacy,questionnaire survey was used to understand the application status of situational teaching in M high school in Panjin city and the implementation of the core literacy of chemistry.On this basis,according to the situational cognitive learning theory,put forward "preparation before class,sorting and accumulation;Situation representation,literacy formation;The teaching strategy is to simplify materials and use them flexibly.The teaching practice is carried out with the examples of "chlorine and its Compounds" and "Iron and its compounds" in compulsory one of human Education Edition.Through the test result analysis,test sample analysis and interview with teachers and students,the development of students' chemistry core literacy was investigated,and the effect of teaching practice was tested.The research shows that the use of situational teaching method can not only attract students' interest in learning,make them like chemistry,but also cultivate their ability to dare to explore and innovate,help students establish correct learning concept,and improve the core quality of chemistry.
