A Study On The Disabilities In Linearfunction Learning And Strategies In Junior High School Students

Linear function is the key and difficult point in junior high school mathematics learning and teaching.The students’ first contact function starts from eighth-grade,Judging from the students’ non-cognitive and cognitive level and their thinking characteristics,there are many obstacles in the learning process of linear function,which will affect their learning of linear function.Therefore,it is of great theoretical significance and practical value to study the learning disabilities and teaching strategies of linear function for junior high school students.This research takes the eighth-grade students of Dongtai experimental middle school in Jiangsu province as the research object,through the questionnaire to understand the cognitive factors and non-cognitive factors that affect the junior high school students’ learning linear function,and uses the univariate and multivariate analysis method in SPSS to analyze the influence of cognitive factors and non-cognitive factors on students’ learning performance at different levels,and uses Excel to analyze the data in the questionnaire.When analyzing the primary function test questions,the SOLO classification theory is used to analyze the level of students’ thinking in solving linear function test questions.The research conclusion has the following aspects:1.The types of students’ linear function learning disorders mainly include emotional disorders,cognitive disorders and operational disorders2.The reason is that the affective disorder is mainly caused by students’ insufficient interest in learning,improper learning motivation,weak learning will,poor learning habits and improper teaching methods.Cognitive impairment ismainly caused by the abstractness of linearfunction,inattention in class,poor ability of knowledge transfer and failure to form a combination of numbers and shapes.Operational obstacles are mainly caused by unclear examination and poor calculation ability.3.According to the linear function learning disorder and its causes,the corresponding teaching strategies are put forward,aiming at affective disorders: in the teaching process,it is necessary to stimulate students’ learning motivation and cultivate their interest in learning;Correct learning attitude and develop a good habit of learning linear function;cultivate students’ good will quality.For cognitive impairment: Situational teaching to deepen concept understanding;pay attention to the interrelation between knowledge and cultivate students’ memory ability;The combination of number and form improves the flexibility of knowledge application.For operational obstacles: help students form a good habit of careful examination of questions and strengthen operation training.
