Teaching Design Of "synthesis And Practice" Of Mathematics In The Upper Years Of Primary School Based On Project Learning

The "comprehensive and practice" of primary school mathematics is a learning activity based on the carrier of problems and students' independent participation.It emphasizes students' comprehensive application of mathematical knowledge,develops students' problem-solving ability,exploration ability and the ability to cooperate with others through exploration,and also enables students to feel the connection between mathematics and actual life,mathematics and other disciplines,and the internal knowledge of mathematics.The teaching of "comprehensive and practice" is of great value to students' learning,but there are some problems in the teaching of it in real life.As a teaching method,project-based learning can let students know how to learn new knowledge and skills,learn to solve problems,develop critical thinking,promote the development of students' higher-order thinking,and enable students to acquire skills in the 21 st century.And the idea it advocates has something in common with "comprehensive and practice".In this study,project-based learning was applied to the "comprehensive and practical" teaching of mathematics in senior grade of primary school,and the "comprehensive and practical" teaching design based on project-based learning was carried out to provide a new theoretical perspective for the "comprehensive and practical" teaching.This paper first uses questionnaire and interview methods to investigate and analyze the teaching status of "comprehensive and practice" in senior years,and finds the following problems: the teaching target orientation is biased towards the mastery of knowledge and skills,content theme selection depends on books,less independent development and design,students' subjectivity fails to give full play to teachers' control of the classroom,the main body of evaluation is simple,the content of evaluation focuses on the acquisition of knowledge and no emphasis on learning to reflect.On the basis of fully grasping the theoretical basis and characteristics of project-based learning,the feasibility of its application to "comprehensive and practice" in senior years is analyzed.Both of them aim at the development of ability,both emphasize practice and operation and both are based on curriculum standards.In addition,its value is: to provide a methodological basis for the teaching of "comprehensive and practice",to promote the development of students' higher-order thinking ability,to improve the ability of teaching content development of teachers,give full play to the students' subjectivity,promote the diversification of the main body and content of evaluation and cultivate the reflective consciousness of students and teachers.Then it is clear that the main process of "comprehensive and practical" teaching design based on project-based learning is: project initiation,planning project evaluation,project implementation,project evaluation and reflection.Then,aiming at some problems existing in the teaching of "comprehensive and practical" in senior years,the teaching design process of project-based learning is carried out with the theme of "campus greening scheme design" and "I am a little nutritionist".Finally,the paper puts forward some suggestions on project-based learning teaching design of "comprehensive and practical" teaching in senior middle school mathematics,in order to provide reference for the improvement of "comprehensive and practical" teaching in senior middle school.
