Research On The Teaching Design Of The Beginning Course Of Junior High School Mathematics Chapter

Content:In order to meet the coming of the era of knowledge economy,at the beginning of this century,the curriculum reform of basic education was carried out.In accordance with the requirements of the curriculum standards,the links between the content of the curriculum and students' life and the development of modern society and science and technology are strengthened,and the requirements of students' learning interests and experiences are paid attention to.Mathematics curriculum has given birth to a variety of organizational forms,vivid multi-edition teaching materials.The compilation of junior middle school mathematics teaching materials has undergone a change.On the basis of the summary at the end of the chapter,"chapter head graph" and "chapter introduction" are added at the beginning of the chapter.The corresponding "chapter beginning lesson" is further concerned by mathematics teachers and teaching researchers.In this study,literature research,questionnaire research and case study were mainly adoptedFirst of all,I read a lot of relevant literature,defined relevant concepts,sought theoretical basis,and reviewed the literature on the existing studies of chapter beginning from the perspectives of teaching status,teaching strategies and teaching design cases Then,relevant investigation and research are carried out to understand the status quo of the teaching implementation of chapter initiationThrough the investigation and analysis of teacher's questionnaire and student's questionnaire,this paper sums up the teaching status of junior middle school mathematics chapter initiation lesson into three aspects:first,most teachers and students are aware of the teaching value of chapter initiation lesson,but only a few teachers have the desire to study chapter initiation lesson teaching.Students do not pay enough attention to chapter head drawing and chapter introduction,and do not realize the consciousness of seeing the forest through the trees.Second,in the teaching of chapter initiation,most teachers pay attention to integrate relevant mathematical historical materials and pay attention to the development process of knowledge,but the teaching has not highlighted the status of chapter initiationThird,students have difficulty in learning the introductory chapter.The teacher excavates the leading role of the chapter in the beginning of the class content,the hidden mathematical thinking method,the development of the appropriate teaching design has a greater room for improvement.Fourth,based on the research and analysis of chapter initiation teaching,the teaching design strategies of four junior middle school mathematics chapter initiation lessons are given.(2)pay attention to the historical roots and be familiar with the growth process of relevant knowledge;(3)absorb the strengths of various families and devote to creating distinctive teaching design;(4)pay attention to variable teaching and strengthen students'in-depth grasp of knowledge.Finally,in the light of the teaching strategy,the paper gives the teaching design cases of"fraction","rotation of graph" and "Pythagorean theorem" based on the variable teaching,taking the mathematics of junior middle school as an example.In a word,the teaching design of the beginning of chapter is a valuable research topic,but there are still many things to be discussed and studied in the process of teaching practice.
