Research On The Causes And Countermeasures Of Learning Disabilities Of "Exponential Function And Logarithmic Function"

This study takes 245 students from a provincial demonstration high school in Shangqiu as the main research object.Firstly,using the methods of literature analysis,investigation,case analysis and quantitative analysis,this paper compiles the learning disability test paper of exponential function and logarithmic function based on the curriculum standard,Through the correlation between the questionnaire and the test paper results and the score rate of the test paper,this paper analyzes the causes of students’ learning disabilities.Based on Hyde’s attribution theory,this paper compiles the students’ questionnaire,and summarizes the types of students’ learning disabilities by analyzing the test paper.Secondly,it designs an interview outline to investigate the front-line teachers’ understanding of students’ learning disabilities,so as to further determine the situation of students’ learning disabilities The learning obstacles in "exponential function and logarithmic function",and analyzes the causes of students’ learning obstacles in "core literacy" and "mathematical thought".Finally,the corresponding countermeasures are put forward according to the causes of learning obstacles.According to the answer card of students’ test paper,analyze the students’ answers;according to the score rate of students’ knowledge points,first get the students’ "exponential function and logarithmic function" The types of module cognitive impairment are basic concept understanding obstacle,knowledge transfer obstacle,old knowledge understanding obstacle and concept application obstacle;secondly,the types of students’ mathematical core literacy obstacles are obtained,that is,the mathematical operation ability is not qualified,the logical reasoning thinking is not strict,the mathematical abstract ability is insufficient,the mathematical modeling consciousness is lack,etc.Finally,the types of obstacles formed by mathematical thought are obtained,that is The thought of function and equation is not perfect,the thought of combination of number and form is not mature,the thought of transformation and transformation is not proficient,the thought of classified discussion is vague,the thought of reverse reasoning is missing,etc.This research analyzes the causes of students’ learning disabilities.Firstly,it analyzes the correlation between test paper scores and questionnaire scores,and obtains the multiple linear regression equation after data analysis with SPSS.It is obtained that the factors affecting students’ academic performance are learning interest,learning attitude,learning methods and teaching situation.Through the communication and analysis with teachers and students,the students’ answer paper is analyzed,and the above influencing factors are analyzed Combining elements with the types of students’ learning disabilities,it is concluded that at the cognitive level,students’ basic concept understanding obstacles are due to insufficient learning interest and lack of interesting situational teaching;knowledge transfer obstacles are due to imperfect grasp of the overall cognition of mathematical knowledge;old knowledge understanding obstacles are due to incorrect learning attitude;concept application obstacles are due to failure to master scientific learning Then,based on interviews,questionnaires and test papers,this paper analyzes the causes of students’ Obstacles in mathematics core literacy and the formation of mathematics thought.Finally,for students in "exponential function and logarithmic function" The types and causes of learning disabilities,combined with the teachers’ teaching methods in the interview,put forward the following countermeasures for students’ learning and teachers’ Teaching: consolidate basic knowledge and master concepts;cultivate core literacy and improve mathematical cognition;improve mathematical thought and problem-solving ability;cultivate metacognitive ability and form good learning habits;study teaching materials and curriculum standards and grasp teaching methods To help students eliminate the interference of psychological factors and environmental factors and improve students’ learning efficiency;monitor teaching behavior and achieve timely feedback and adjustment.Finally,design targeted teaching programs according to constructivism theory to provide teaching reference for teachers to guide students to improve learning disabilities.
