The Teaching Design Of The Beginning Lesson Of Chapter Of The Seventh Grade Mathematics Based On The Total Construction

The new curriculum concept emphasizes the overall grasping course,guides students to feel the overall nature of mathematics,conveys the value orientation of mathematics,penetrate mathematical ideological methods,and promote the development of students’ core literacy.As a chapter or module,the first class has the role of macro-lead.The starting lesson of the good chapter is conducive to helping students build a knowledge framework,clarify the direction of learning,understand the meaning of learning this chapter,penetrate mathematical methods,and cultivate systems.Thinking and overall concept.However,in actual teaching,the advantages of Zhang Xi’s first lesson have not been well displayed.Therefore,the starting class based on the overall construction of the class has brought new ideas to the teaching of the first lesson.This article mainly adopts the literature research method,interview research method,education observation method,and questionnaire survey method.On the basis,teaching practice studies on the teaching practice of the seventh grade "integrated addition and subtraction" chapter.First of all,sort out the relevant literature and explain the concepts of the beginning of the chapter and the overall construction of teaching,and find the theoretical basis of research;second,through the questionnaire,understand the feedback and expectations of the students in the current stage of the chapter in the current junior high school stage,understand the mathematics teacher The attitude and implementation of the starting class teaching;again,the design principles of the seventh grade mathematics chapter based on the overall construction of the overall construction class were proposed to classify the beginning of the chapter.Finally,based on the overall construction theory,the seventh grade mathematics " The union and subtraction of the union started the teaching design,and after teaching practice,the teacher and students were interviewed,analyzed their teaching effects,and conducted reflection and evaluation in order to provide a certain reference for first-line teachers’ teaching.The main conclusions of this study are: 1.The results of the current status survey show that teachers recognize the importance of the first lesson,but the current teaching status is not optimistic;teachers have not perceived the lessons of the beginning of the chapter,and the lesson preparation is not sufficient;The consciousness of the design chapter starts the lesson,but the teaching design ability is insufficient;the learning effect of the student chapter is not effective;the students believe that the teaching of the first lesson should enhance the exploration,culture and correlation.2.Several principles of teaching design based on the seventh grade mathematics chapter based on the overall constructed: the principles of integrity,logical principles,subjective principles,retrospective principles,and process principles.3.The starting lesson of the junior high school mathematics chapter can be divided into the starting class of the module,the starting class along the way,and the terminal starting class.4.The analysis of the results of teaching practice can be seen that teachers and students are more recognized by the first class teaching based on the overall construction.The consciousness,initiative,directionality and efficiency of learning can cultivate students’ overall analysis ability and systematic thinking,and promote students to change from "learning" to "learning".
