The Study On The Teaching Design Of The Chapter's Introductory Lesson In Middle School

Great importance should be attached to the chapter's introductory lesson for its position and role of commanding the entire chapter.However,in the actual mathematics teaching process,it has not been effectively implemented.The author aims to study the teaching design of chapter's introductory lesson in middle schools' math teaching with the hope of bringing inspiration to the innovative teaching method of middle school math teachers.This paper first uses the documentary analysis method to analyze the connotation and characteristics as well as the teaching design theory of the chapter's introductory lesson on the basis of a large number of relevant research results in the academic community.Besides,this paper adopts the case analysis method to explore the principles and approaches for the teaching design of the chapter's introductory lesson of middle school mathematics according to the above research results.Finally,teaching materials are excerpted from the middle school mathematics textbooks published by Beijing Normal University Press.Also,the case analysis and questionnaire method are used to analyze and elaborate the teaching design of the junior mathematics 'introductory lesson,and then design and implement the teaching cases.This study has initially obtained the following conclusions:(1)the teaching design of the chapter's introductory lesson in this article is based on the mathematics curriculum standards and the actual situation of the students.Combine the specific content with the teaching materials to creatively organize the teaching activities.Guide students to understand the relevant background,knowledge structure,logic system,and value of the chapter,and help students clarify the contents,characteristics and learning methods of this chapter,and thus form a teaching scheme.(2)the chapter's introductory lesson of middle school mathematics has three characteristics: comprehensive teachingcontent,rich ideological content,and high implicit value;(3)The five principles that should be fulfilled in the instructional design of the chapter's introductory lesson of the middle school mathematics are the overall principle,the principle of subjectivity,the principle of development,the principle of process,and the principle of stimulating interest.(4)The four ways of teaching design for the chapter's introductory lesson of the middle school mathematics are: introducing the introduction,highlighting the charm of mathematics;creating backgrounds,inspiring cognitive conflicts;designing processes,grasping the context of knowledge;experiencing knowledge generation by using analogy to old knowledge.
