A Study On The Causes And Countermeasures Of Linear Function Learning Difficulties Of Junior High School Students After The Epidemic Situation Resumes Classes

New crown epidemic broke out across the country,from the beginning of 2020 until march epidemic has yet to be fully control,therefore,classes took off spring of primary and secondary schools across the country measures to actively carry out the primary and secondary schools closed constantly teach by the department of education requirements,organize students to online learning,the teacher taught in the form of recorded live class or class.However,due to the sudden outbreak of the epidemic,this is the first time for both teachers and students to take the contact network class.Compared with the traditional offline teaching method,online learning is more convenient.However,due to its intelligence and non-contact,higher requirements are put forward for teachers' teaching and students' learning.The ninth chapter,"The Relationship between Variables",is the basis for students to learn primary functions,and is also the critical period for students to form abstract logical thinking.The degree of achievement of teaching objectives in this part greatly affects the subsequent learning.It is understood that during the epidemic period,students learned this part of content through online courses,so teachers could not accurately grasp the situation of students,especially the growth of students' logical thinking,which laid a hidden danger for the learning of primary function in the first volume of the second grade.During the internship in Taishan Experimental Middle School,the author found that after the epidemic resumed classes,freshmen of Grade 2019 found it more difficult and encountered more problems in a function learning process compared with students of Grade 2018,which led to the failure of the established teaching plan of the mathematics teachers of Grade 2 to achieve good teaching results.The author reads a large number of literature studies on learning difficulties in mathematics and learning difficulties in linear functions,and sorted out the current status and theoretical foundations of related researches on learning difficulties in linear functions.The research content of this article mainly focuses on the typical learning difficulties and their causes of the primary function of the second grade students after the resumption of the epidemic,and the targeted strategies to deal with the learning difficulties of the students after the resumption of classes.This article selects the 2019 students of Taishan Experimental Middle School as the survey objects.Through the control test of the 2019 and 2018 students,the student questionnaire survey,and the teacher interview survey,the students' difficulty in learning a function after the resumption of the epidemic is summarized,including the following Six aspects:(1)Some students find it difficult to distinguish independent variable from dependent variable(2)Some students have difficulty making tables according to the information in the questions(3)Some students are difficult to express by the topic information column(4)It is difficult for some students to convert the combination of numbers and shapes(5)Some students lack ideas and awareness of mathematical models(6)Some students still have thinking inertia in mathematics learningIn the process of investigation and research,the author found that students in both grades before and after the epidemic would have learning difficulties in the above six aspects during the learning process of a function.However,compared with the 2018 students,the 2019 students after the resumption of classes showed The learning difficulties of the primary function are more serious,and the number of students with learning difficulties is relatively large,mainly due to the poor grasp of the students' knowledge during the online course of the epidemic,and the obstacles to the development of thinking.In order to deal with the more serious learning difficulties in the primary function learning of the second grade students after the resumption of the epidemic,the author combined the student questionnaire survey data and the teacher interview survey results to propose targeted teaching strategies to solve the students' primary function learning difficulties,which mainly include the following seven aspects :(1)Use "compensation-type micro-lesson" to overcome important and difficult points in learning(2)Use the "classification of standards" to improve students' performance(3)Optimize teaching design and enhance students' interest in learning(4)strengthen the home-school interaction,overcome the disadvantages of network learning(5)Pay attention to the cohesion of textbooks and urge students to summarize(6)Infiltrate model ideas to cultivate students' core qualities(7)Overcome inert thinking and transform thinking in timeThis article through to the disease after the resumption of school second day student a function to the study on formation cause of the learning difficulties,which provided reference for the second day mathematics teacher improving teaching scheme,for the primary and secondary school teachers to carry out online hybrid teaching to provide theoretical support,for the future similar outbreak closed case teacher's teaching to provide practical and feasible teaching methods and countermeasures.
