Research On The Structured Instructional Design Of The Beginning Class Of The Junior Middle School Mathematics Chapter

One of the core tasks of mathematics teaching is to direct students to discover and recreate.After the new curriculum reform,we found that whether the PEP edition,the Beijing Normal University version or the Soviet Education of the junior high school mathematics textbook,there are chapter introductions,chapter drawings at the beginning of each chapter,and some even list the learning goal of this section.The content itself can be expanded as a guiding learning material to stimulate students'interest in learning and guide students to actively take part in learning exercises.However,the present situation of teaching is as follows:whether theoretical research or practical exploration,"chapter starting class" has not obtaining the concern it merited.Therefore,the teaching of the beginning of mathematics chapter in junior middle school has become a problem that we need to study urgently.By studying the current teaching situation of junior middle school mathematics chapters,this paper provides a teaching model for the implementation of Junior Mathematics chapter start class,which is structured teaching of junior middle school mathematics chapters.This aspect can optimize the teaching of teacher;on the other hand,it can also effectively promote students' learning,which has certain guiding and practical significance.This article mainly uses the means of literature research,questionnaire survey,observation and interview and so on.The main research ideas are as follows:First of all,through reading books and articles related to "chapter start class" and "structured teaching",we can understand the current research status of the related chapters' start class and structured teaching mode.Secondly,we define the core of structured teaching design of junior middle school mathematics chapter start class,and seek theoretical support for structured teaching design of junior middle school mathematics chapter start class;in addition,it also makes a comparative analysis of the contents of the chapters in the three versions of Mathematics Textbooks in junior middle school,and finds the combination point of "structured teaching" and "junior mathematics chapter start class".Then,a questionnaire was conducted between 200 students and 50 teachers in 2 middle schools in Xi'an,and we understood the present situation and problems of the beginning of the mathematics chapter of junior middle school.Finally,through the study of "mathematics curriculum standards of compulsory education",combined with literature data and questionnaire survey results before the review,put forward a structured teaching design of junior high school mathematics teaching strategy,the chapter starts with the basic principles and basic methods,and the implementation of the teaching process,construct the structured model of teaching design of junior middle school mathematics part start class.In addition,this paper provides two cases of structured teaching design beginning lesson included "One element first order equation" and "Congruent triangles".Through the observation interview and experimental research to analyze the implementation effect of structured teaching of "One element first order equation" starting class,and verify the validity of the research.The innovation of this paper is that provide a systematic research and analysis for the structured teaching design of the junior middle school mathematics chapter start class through the combination of theoretical research and practical research.In view of the problems in the structured teaching design of the beginning of the junior middle school mathematics chapter,the corresponding teaching design tactic is given.Besides,this paper expounds the basic principles and basics methods of structured teaching design of junior middle school mathematics chapter start class,and gives the basic process of teaching implementation,and a new teaching model is constructed.
