Research On The Learning Situation Of Abstract Function Of The Senior High School Students

In basic education,functions play an important role in students' mathematics learning.With the continuous improvement of high school mathematics curriculum standards and mathematics core literacy on students' general literacy requirements for mathematics,the requirements for students' function-related knowledge are also more clear.Abstract function as a difficult part of the function part of the knowledge,the specific nature of the function and characteristics of the function in the form of non-analytical questions,can fully cultivate the students ability to abstract and summarize,logical reasoning ability and other aspects of training and exercise.In this paper,a lot of literature related to abstract functions are consulted and analyzed,and the students 'learning status of abstract functions is investigated and analyzed by means of questionnaires,test volumes,and teacher-student interviews.Among them,the survey was conducted on 249 high school students in two ordinary high schools in Heilongjiang Province.249 high school students in an ordinary high school.The contents of the study include: through questionnaires and questionnaires to explore the current problems in the abstract function learning of high school students,the reasons that affect the students' abstract function learning obstacles,and measures to improve student mastery of abstract function problems.Through the survey,it is found that there are many problems in the abstract function learning of the students.Among them,there are problems in the four aspects of the basic knowledge and ability to grasp the level of problem-solving methods and the use of skills,learning attitude and learning habits level and other external factors.Under these major aspects,including students' specific details of small details,such as the student function definition field reflected in the test volume is unclear,the monotonicity of the function is not clearly defined,the given interval is ignored,and the method of substitution is used.Inaccuracy,usage of indefinite assignment methods,etc.At the end of the article,aiming at the problems existing in this part of students' knowledge learning,they provide some ideas and suggestions for learning abstract functions from the aspects of teachers,students,and teaching environment.
