Research On The Difficulties Of Sequence Learning In Senior High School Students And Their Solving Strategies

As a kind of special function,sequence connects mathematical abstraction with real life.Under the promotion of core accomplishment,students' cognition of sequence is no longer just the learning of basic knowledge and basic formulas.It's about discovering the idea of function,the idea of combination of number and shape.Incorporate it into the core accomplishment to improve the learning of the whole sequence.The teaching of sequence by teachers is no longer just the explanation of "pure knowledge" in textbooks.Mathematics culture should be integrated into the teaching design of sequence.With the teaching method of inquiry,it is not easy for students to understand the abstract concepts such as "discovery-proposal-verification-summarization",so as to run through the learning of the whole sequence.In addition,sequence of number also plays an important role in the college entrance examination,which is the required content of the college entrance examination over the years,and is highly comprehensive.Students often feel at a loss when faced with sequence problems.Therefore,what kind of teaching methods should teachers adopt? How should students study effectively? Become a problem to think about now.This paper is on the basis of consulting and sorting out related literature at home and abroad.It is supported by Wiener's theory of attribution,Bruner's discovery learning theory based on constructivism and General high school mathematics curriculum standards(2017 edition).Through the questionnaire,test volume survey and interview of high school students in each grade,the study status of high school students on sequence of learning was observed.As well as interviews with math teachers in different grades,we can find out the difficulties high school students have in learning sequence.Through interviews with teachers,this paper summarizes the problems and shortcomings of teachers and students in and out of the classroom,and analyzes and improves the shortcomings of traditional sequence teaching.The study found that the three grades of high school students have difficulties in learning sequence.On the one hand,the abstract rigor of the subject,the teacher's grasp of the classroom and the environmental factors will become the external factors of high school students' difficulty in learning sequence.On the other hand,students' interest and will in learning sequence,their lack of cognition and comprehension,and their lack of thinking will become the internal factors of high school students' difficulty in learning sequence.Combined with the above internal and external factors,from the perspective of teachers' teaching and students' learning,this paper proposes corresponding solutions to these factors,which is the focus of this paper.
