Research On The Application Of Advanced Organizer Strategy In Chemistry Teaching

The balance system is an important part of the high school chemistry curriculum,which almost runs through the entire high school chemistry knowledge system.According to the current high school chemistry syllabus,one of the important contents is chemical balance,which is the theoretical basis for in-depth understanding of the other three balances.In the branch of the chemical balance system,the balance of insoluble electrolytes has a greater relevance to other branches in the study of the balance system.It is one of the compulsory examinations for college entrance examinations in the past years,and it is also one of the difficulties reflected by students.How to use scientific and effective teaching strategies to help students learn the difficulty of dissolving balance knowledge of insoluble electrolytes and help each other to learn other balance knowledge systems is one of the topics that high school chemistry teachers should consider.In the teaching of junior middle school,students will have a certain understanding of balance and chemical balance,which will lay a foundation for the comparative system of high school to study the balance system.The advanced organizer strategy plays an important role in the study of chemical balance,and this strategy can be widely and widely used in a balanced knowledge system.Therefore,this article starts with this and provides a reference for the teaching of the dissolution of insoluble electrolytes.Based on the characteristics of the balanced knowledge system,this article takes the advanced organizer strategy as the theoretical guidance,uses the teaching experiment method to design the knowledge of the dissolution balance of high-level chemistry insoluble electrolyte,and teaches the effectiveness of the teaching strategy in the insoluble electrolyte balance Carry out the inspection.The structure is as follows:The first part briefly introduces the background of the topic and the significance of the research of this topic.Furthermore,the main research methods and methods to be adopted in this article are briefly introduced,and the purpose and research planning of different research methods and methods are clarified.The second part lays the theoretical and practical foundation of this article.Briefly explain the basic connotation,classification,application and implementation strategies of relevant technical theories to clarify the scope and theoretical framework of the research in this article;secondly,introduce the chemical equilibrium theory,as the teaching knowledge point that this article intends to solve,this part of The concepts and theories are introduced in detail,and the characteristics of the education content are clarified,which lays a theoretical foundation for the teaching design below;finally,a brief introduction to the leading organizer strategy and its implementation steps is made to clarify the basic process and ideas of the teaching strategy.The third part is the current situation investigation part.The questionnaire survey method and interview method are used to investigate the current status of the high school chemistry balance knowledge system to obtain the knowledge of the balance knowledge system between the students and teachers.Balance the learning and mastering of knowledge,and lay a realistic basis for the teaching design below.The fourth part is the teaching design part,combined with the previous survey results,to carry out the dissolving balance teaching design of the insoluble electrolyte of the prior organizer,select the specific teaching content,and interpret the specific content of the relevant knowledge points and the teaching objectives;And on this basis,combined with the theoretical framework of the advanced organizer,design teaching experiments,conduct pre-test and specific teaching implementation,and further conduct post-test to obtain teaching results.The fifth part is the summary and reflection of the research.Through the specific implementation of the advance organizer teaching,the effectiveness of the advance organizer theory in balancing knowledge teaching is proved,and the shortcomings of the research are summarized.Through the teaching research of this article,it is concluded:(1)The use of advanced organizer strategies is conducive to the teaching of the dissolution of insoluble electrolytes,especially in the breakthrough and mastering of difficult points,the teaching effect is remarkable;(2)Migrating the relevant content of chemical balance to the dissolution balance of insoluble electrolyte will help students learn and apply the dissolution balance of insoluble electrolyte.Therefore,the advanced organizer strategy can significantly improve students' learning and mastering the knowledge level of insoluble electrolyte dissolution balance,which is an effective teaching strategy.(3)In the process of implementing instructional design,part of the core qualities required by the new curriculum standards are run through.After implementation,the concept of isolation in students' minds is connected to form a complete knowledge system,which is more conducive to students to answer innovative questions in the exam.
