Investigation And Research On "Problem String" Teaching In Mathematics Class In Senior High School

Confucius said : " doubt is the beginning of thinking,the end of learning ",it can be seen that the problem has a vital role in learning.In recent years,an innovative teaching mode," problem string " teaching gradually emerged.Compared with the traditional teaching mode,which is mainly taught by teachers,"question string " teaching can effectively exercise students' problem consciousness,improve students' problem ability,and thus improve classroom efficiency.As a result,more and more mathematics education researchers and teachers pay attention to it.The current situation of "problem string" teaching in high school mathematics classroom has also become the problem to be studied in this paper.This paper mainly adopts four research methods: literature method,questionnaire method,interview method and case analysis method,and carries out the investigation and research on the present situation of "question string" teaching in high school mathematics classroom with relevant theoretical basis.First of all,a questionnaire survey was carried out on the mathematics teachers of two high schools,and interviews were conducted with individual teachers.At the same time,the author analyzed and discussed the problems of the teachers' understanding,usage and design ability of the "question string" teaching in their senior high schools.Based on the above investigation,this paper analyzes the present situation of "problem string" teaching in high school mathematics classroom: generally,teachers already have the consciousness of "problem string" teaching,but they are optimistic about the design and use of "problem string ",which is manifested in four aspects: difficulty and discomfort problems,unclear points of problems,weak connection of problems and insufficient answers to questions.Finally,aiming at the problems existing in the present situation of "problem string" teaching,the corresponding teaching suggestions are put forward.
