Research On The Current Situation And Problems Of The Practice Of Mathematics "number And Algebra" In The Upper Primary School Mathematics

Classroom practice generally is set after the completion of the new knowledge learning,with exercises as the carrier to carry out activities and self consolidating and cooperative inquiry as the main organization form of exercise activities.Classroom practice is an important part of classroom teaching.It is an important means to consolidate and review the mathematics knowledge.It is the basic way to master the mental skill and movement skill.Mathematics classroom practice refers to the activity in the mathematics classroom.This study reviewed a large number of related literature,questionnaire survey of high grade primary school students and conducted the first line of mathematics teachers through questionnaires and interviews.At the same time,the author used of the opportunity to practice,enter the classroom,and selected the different types classroom practice cases of "Number and Algebra".After the analysis of the case,the author found the merits and deficiencies.Through analysis and arrangement,investigation and case study,the author summed up a series of problems of "Number and Algebra" classroom practice,in the current primary school high grade,such as teachers' understanding of the improper classroom practice is not correct and teachers have insufficient attention to the classroom exercises and less focus on the students.the design is not scientific,etc.The author analyzed the causes of the problemsfrom four aspects:the external environment,the teachers themselves,the students,the design of teaching materialsThe study positions of the value of the practice in the class,and presents the design principles:purposeful principle,hierarchy principle,the principle of typical and appropriate,the principle of flexibility and diversity,the principle of interest and life,the principle of development of thinking and flexibility,etc,and summarizes the main problems that should be paid attention to in the design of classroom practice.Classroom practice connected with new teaching,and can not be separated from teaching content.In this study,the author took "constant law of merchant" as an example from "number and Algebra" to design the classroom practice,and reflect the advantages and disadvantages of the design.It is recommended to pay attention to three aspects:the design of the exercise before class,the implementation of the practice in the class,and reviewing after class.By dissolving them one by one,the practice design can be optimize.
