The Practical Study On "Problem-explanation" By Students In The Mathematics Review Classes In Grade Three Of High School

.In most cases,mathematics review classes in grade three of high school is subordinated to teachers? analyzing and talking.As a result,there are few chances for students to express themselves.From the viewpoint of teachers,they put more attention to course scheduling and the results presented by students but ignore their thinking process as well as their main-body role in class.In order to improve the thinking ability and the ability of analyzing and solving problem of the students,we try to encourage them to carry out “Problem-Explanation” in mathematics review classes.This paper is devoted to studying the “Problem-Explanation” in mathematics review classes in grade three of high school.“Problem-Explanation” can make students reorganize and reconstruct the knowledge they have been obtained,which can improve the timeliness of the review classes and enhance the problem awareness and mathematics thinking ability of the students.This paper is divided into four chapters.In chapter one,we state the research background and significance of “Problem-Explanation” in mathematics review classes in grade three of high school and do a detailed analyzing about the current situations of“Problem-Explanation” and mathematics review classes in grade three of high school respectively and then give the concept of “Problem-Explanation” correspondingly.In Chapter two,we are aiming to represent the questionnaire of the current situation of“Problem-Explanation” and its corresponding data analysis follows.In chapter three,we state that how to carry out the practical research of “Problem-Explanation” in mathematics review classes in grade three of high school,which includes three aspects:inspiring the students to try “Problem-Explanation”,guiding the students carry out“Problem-Explanation” on their own initiative and carrying out “problem-explanation”on a deep level.By doing the follow-up surveys of two students in grade three of high school,we study the influence process of “Problem-Explanation” to their thinkingmodels;by using interview method to those students who take part in the practical study process,we know their opinions about the teaching form of “Problem-Explanation”.In chapter four,we conclude the practical research of “Problem-Explanation” in mathematics review classes in grade three of high school and give some matters to be noticed when carrying out the teaching form of “Problem-Explanation”.
