Research On The Application Of Online And Offline Blended Teaching In Junior High School Mathematics Teaching

With the advancement of online modern development and education reform,the online and offline mixed teaching mode has emerged as the times require.The application of this teaching model in higher education and technical writing is the research topic of this paper.This study is divided into seven chapters.The first chapter introduces the research background,research purpose and significance of the blended teaching model,analyzes the research status of the blended teaching model at home and abroad,and conceives the research technical route.The second chapter mainly uses the literature analysis method to give the concept of online teaching,offline teaching and blended teaching,summarizes humanistic learning theory,constructivist learning theory and mastery learning theory,and guides blended teaching based on the above theories.The third chapter adopts the method of questionnaire survey and interview to conduct relevant investigation and research on the learning situation of junior high school students,the teaching situation of teachers,and teaching hardware equipment,etc.,analyzes the problems existing in the current junior high school mathematics classroom,and implements mixed methods in junior high school mathematics teaching.Feasibility analysis of teaching mode.The fourth chapter,according to the requirements of the society and the "Curriculum Standards",combined with the existing problems in the current junior high school mathematics classroom,puts forward the optimization strategy of the mixed teaching mode in the junior high school mathematics teaching.The fifth chapter gives the design principle and specific process of blended teaching,and uses the case analysis method to design the teaching case of "The Converse Theorem of the Pythagorean Theorem" under the blended teaching mode.Comparative analysis of students’ pre-test and post-test scores is used to illustrate the effect of using blended teaching in junior high school mathematics teaching.The sixth chapter analyzes the advantages of blended teaching in junior high school mathematics teaching based on the author’s investigation and practical experience.The seventh chapter summarizes the work and shortcomings of this paper,and looks forward to the development and application of the blended teaching model in mathematics teaching in junior high schools.The research results of this paper show that the blended teaching mode combines the advantages of online teaching and offline classrooms,breaks the constraints of traditional teaching time and space,and avoids the cramming teaching method in traditional teaching.This teaching mode pays attention to the development of the educational subject and individualized development,pays attention to the learning process and evaluation,can cultivate students’ problem-solving ability,improve students’ innovative spirit and comprehensive quality,and realize the effective teaching of junior high school mathematics.
