Optimization And Application Of The Teaching Resources Of "comprehensive And Practical" In Junior High School Mathematics

The mathematics curriculum standard has put forward the new request to the junior middle school mathematics "synthesis and the practice" curriculum implementation.In order to implement the requirements of the new curriculum standards,the people's education edition of the junior high school mathematics textbooks added "subject learning","mathematical activities" and other sectors.These plates are the specific implementation of the "comprehensive and practical" field,which plays an important role in the development of students' mathematical knowledge,the ability to explore,analyze and solve problems.In the world,the main developed countries have long attached great importance to the comprehensive ability of students,the cultivation of mathematical application ability.This is evident in their mathematical standards.Therefore,the research on the problem of "integration and practice" is the trend of world mathematics education.The teaching of "comprehensive and practical" plays an important role in the development of teachers and students.In this paper,through the excavation of the excellent teaching resources in teaching materials,teaching resources optimization methods are summarized in order to provide some help for teachers.This paper is divided into seven parts:The first part describes the research background,purpose and significance,and research status.The second part is the definition of relevant concepts and theoretical basis.This paper expounds the concept of "integration and practice" and "teaching resources".It also explains the theory of "learning by doing","constructivism" and "the zone of proximal development".The third part of the questionnaire and interviews to understand: "comprehensive and practical" teaching resources are relatively scarce,teaching materials in the teaching and learning materials on the "comprehensive and practical".There are some problems in the teaching materials,such as less information,lack of necessary background knowledge,neglect of the creation of the situation,the problem is not conducive to the guidance of students thinking,etc..These problems seriously affect the implementation of the "comprehensive and practical" curriculum.In the fourth part,the author by reading the literature and combined with their own teaching practice,the mathematics textbook of "comprehensive and practice" plate setting are analyzed and summarized,summed up some types of "comprehensive and practice courses: mathematical modeling,mathematics experiments,statistics,mathematics design,research,development of mathematics class,and the characteristics of these types are described.In the fifth part,the author thinks that we should optimize the teaching resources from six aspects: choosing the right subject,the integration of knowledge,situation,problem design,choose the suitable teaching mode,teaching reflection.Especially in the aspect of the topic of "comprehensive and practice",the author combines the teaching practice experience,selects some practical problems in the teaching material,and gives some other reference topics.In the integration of the knowledge points,the author thinks that we should fully tap the hidden value of education,and combine the knowledge in class and extracurricular knowledge.In the creation of the situation,we should pay attention to the reality of the situation,open and interesting,according to the needs of teaching to choose the right way to create scenarios.In the sixth part,the author provides two teaching cases,and analyzes the effect of the implementation of the comprehensive and practical courses.The seventh part summarizes the main conclusions of the study,and puts forward the inadequacies.
