Research On The Application Of Context In Chemistry Classroom Teaching In Senior High Schools

The curriculum reform of basic education requires that teaching be carried out around the content of the course and student life and social development to meet the psychological needs of students and prepare for the challenges of the future society.The teaching based on the context is an important feature to give play to the subjectivity of students' learning and to strengthen the practical application of knowledge.Linking chemistry with social reality,realizing the transfer of knowledge,achieving the application of learning,and comprehensively improving comprehensive literacy.The knowledge of elements and their compounds in the actual teaching is easy to understand and difficult to use.Therefore,the introduction of the context into the teaching of elemental compounds,starting from the existing knowledge of students,using classroom resources and technology to create contextual context,will The effective combination of knowledge and situation enables students to construct knowledge in context,help students to deepen their memory and understanding of knowledge,and improve their interest in learning and the ability to apply knowledge to solve problems.The paper consists of six parts.The introduction part discusses the background of the research based on this research and points out the research status of the world at home and abroad,points out the significance of the research and puts forward the research content and research methods of the thesis;The second chapter is the theoretical basis and core concept definition of the thesis.This part mainly discusses the theory of constructivism and the theory of contextual learning and combs the concept of contextual and contextual learning;The third chapter explores the structure,teaching strategies and core elements of the chemistry classroom based on the context of the theory of constructivism and the theory of contextual learning;The fourth chapter is the application research of Jingmai in chemistry classroom teaching.This part takes the quasi-experimental method as the basic method,selects two classes of a middle school in Shangluo City,Shaanxi Province asthe research object,and understands the situation through questionnaire survey and quasi-experimental method.The application of pulse in the teaching of elemental compounds,and discusses the design of the entire research process,including the research object,the choice of research tools and the research process;The fifth chapter is the data analysis.Through the analysis of the collected questionnaire data and student scores,the effectiveness of the empirical context in the elemental compound classroom teaching;The sixth chapter is the conclusion and outlook.Through the teaching practice,it is found that the context of the classroom helps students to improve their interest in learning,change their learning style and improve their academic performance.At the same time,they also put forward higher requirements for teachers in the new era.In addition,it reflects on the inadequacies of the research and provides new ideas for further improving the application of the context in chemistry classroom teaching.
