The Practice Research Of Mathematical Preparatory Work For The Second Phase In Primary School Under The Concept Of Student-oriented Educational Principle

With the implementation of quality-oriented education,the principal position of students has become more and more prominent.Class teaching model has gradually shifted from "how to teach" for students to "how to learn".The concept of student-oriented educational principle is also gradually accepted by people.Preparatory work is the important form of the concept of student-oriented educational principle.In recent years,more and more scholars begin to study the preparatory homework in each subject in middle school,but there are few in-depth studies on mathematical preparatory homework in primary school.This study starts with the problem that how to design reasonable and effective mathematical preparatory work and apply it to pedagogical practice in primary school.This paper main researches two aspects of the problem: On one hand,I investigated the present conditions on the development of mathematical preparatory work for the second phase in primary school and to analyze the results of the survey.On the other hand,I put forward improvement strategies for the design of mathematical preparatory work in primary school,then I put forward specific design strategies in combination with different types of math class.The results showed that the content of problem is teachers' problem,such as inaccurate positioning of the preparatory work for the second phase,a lot of exercises,monotonous form,and Inadequate evaluation feedback.In this paper,I based on the achievement of former scholars,and proposed to improve the design of mathematical preparatory work in primary school.It will be helpful for teachers to clarify the teaching requirements of the second phase,and not only to realize the profound meaning of mathematical preparatory work,but also to pinpoint design principles and assessment on the work.In terms of the design principles,the design of the mathematical preparatory work in primary schools should be around the teaching content closely.According to the specific learning situation,we should pay attention to the connection between the new old knowledge the relation.We also should follow the guiding principle,practical principle,fundamental principle,interesting principle and open principle.In terms of the work evaluation,we should integrate with self-evaluation,mutual evaluation and teacher evaluation.In order to make this research more practical,this paper expounds the purpose of the pre-assignment design and puts forward the specific strategies for the pre-assignment design of new lessons and review lessons according to the characteristic of different class type.The preparatory work in new lessons lays stress on students' life experience and the relations of new knowledge and anterior knowledge.It lay stress on the experience and the course of obtaining knowledge.Design the work according to the four steps of review,exploring new knowledge,questioning and assessment.The preparatory work of review lessons not only sorts out the knowledge,but also focuses on the construction of the knowledge system.Teachers present the practical work in the form of teasing out knowledge,analysing example and setting out questions.After a year of comparative experimental research,It is found that the strategy proposed in this paper is feasible.The implementation of preparatory work helps students develop good habits of learning mathematics.It can improve students' mathematical learning attitude and students' mathematics scores to narrow the differences among students to some extent.
