Investigation And Research On The Current Situation Of Functional Learning Of Junior Three Students

In junior middle school mathematics teaching,function is one of the important contents.It is not only the focus and difficulty of student learning,but also the difficulty of teacher teaching.The learning process of function permeates important mathematical ideas such as the combination of number and form,classification and discussion,etc.Learning functions also cultivates students' mathematical ability.At the same time,functions are the focus of the annual high school entrance examination,and the forms of questions are variable.Through the analysis of the Xining City mid-term exam questions in recent years,the final major questions are the comprehensive knowledge of functions.It is of positive significance to carry out investigation and research on the status quo.With the help of the investigation results,students are found to have problems in function learning,and the reasons for these problems are analyzed according to the problems,and then opinions are given from both students and teachers in order to give students learning and teachers Give some help.The thesis used literature research method,survey method,statistical method and interview method to survey students and teachers.This survey was conducted in a common middle school in Xining City,and the survey results were statistically analyzed using SPSS software.Students have the following problems in function learning:(1)poor grasp of the concept of functions;(2)too one-sided understanding of function images and properties(3)poor understanding of the relationship between functions and equations(inequalities)(4)Exploration found that the ability is not strong(5)The actual application ability of the function is not strong.Through interview records,it was found that teachers had the following problems:(1)Not paying enough attention to concept lessons;(2)Single teaching mode;(3)Not paying enough attention to students 'drawing and drawing ability;(4)Not giving students more independent thinking and independent learning Time;(5)did not reflect frequently.In response to the problems reflected in the survey results,the author gives their own opinions from the students and teachers.First of all,students should do thefollowing:(1)develop good learning habits;(2)master the correct learning methods;(3)correct learning attitude;(4)do a good job in psychological construction.Secondly,teachers should do the following:(1)pay attention to the cultivation of students' ability to draw pictures;(2)pay attention to the teaching of concept classes;(3)help students increase their interest in functions;(5)Do regular teaching reflection.
