Research On Teaching Practice Of High School Chemistry Modeling Based On Autonomous Learning

In recent years,modeling teaching has become an important means of education.Through modeling teaching,teachers can effectively stimulate students' interest in learning,improve students' core quality of subject,cultivate students' creative thinking,help students develop good learning habits and promote their learning ability.At the same time,modeling teaching focuses on the guidance of teachers,the cooperation between teachers and students,and the cooperation between students,which reflects the people-oriented teaching concept and teaches students the initiative in class.It is a scientific and efficient teaching method.But for now,the study of modeling of chemical teaching in China preferred in theory,but under the condition of autonomous learning of high school chemistry modeling of practical study is less,so the existing research results can provide a line of high school chemistry teachers' teaching some theoretical methods,cannot effectively for the teaching of high school chemistry teacher practice.This paper starts from the research on the teaching practice of high school chemistry modeling based on autonomous learning,takes "autonomous learning" as the starting point,and takes "practice" as the main way of research to carry out relevant research,so as to provide more powerful reference for chemistry teachers in first-line high schools.Specifically,based on the model of teaching related concept and theory on the basis of domestic and foreign research situation,and determine the direction of the study,thinking,and the research content and method,and then design the questionnaire on the status quo of teaching high school chemistry autonomous modeling and analysis,as a case study of the chemical reaction principle of modeling based on autonomous learning of high school chemistry teaching practice analysis,determine the principles and methods of autonomous model high school chemistry teaching.Then with the method of action research to carry out the teaching of high school chemistry "galvanic battery","salt hydrolysis" two courses,and a comprehensive evaluation of the teaching process and results,the existing problems in the action research and put forward improvement measures,finally draw the conclusion of the research.Through the in-depth research of this paper,three main conclusions are drawn:First,the teaching of chemical modeling in senior high school based on independent learning can concretize the abstract chemical knowledge,stimulate students' interest in learning chemistry,effectively improve students' core quality of chemistry discipline,and help students improve their thinking and creative ability.It is a scientific and effective teaching method.Second,according to the survey results,the current first-line chemistry high school teachers have problems in model teaching,such as less frequency of model teaching,inaccurate model application,unclear role of teachers in model teaching,and single model teaching method.Thirdly,chemical modeling teaching based on autonomous learning requires teachers to set up reasonable teaching scenarios,start with model objectives,model construction,model improvement and model application,and finally evaluate the model teaching process,thus forming a systematic high school chemistry model teaching system.
