Research On The Learning Obstacles Andcountermeasures Of Junior High Schoolstudents' "Triangle Congruence"

The convening of the two sessions in 2018 put forward a new course of action for education.It can be seen that the reform of education is advancing with the times.The call for students to “reduce” is getting louder and louder,so how to get students to learn knowledge easily is a key point.Therefore,it is very necessary to study the learning difficulties of students in a certain chapter.In this paper,the author mainly studies the learning disabilities of the content of the eighth grade students in the section of the decision triangle learning,and finally come to some effective solutions or control the students to cause learning disabilities.As we all know,the content of the triangle's contingency must be considered during the middle school stage.It usually appears in the form of big questions in the middle exam.In addition,this chapter is very helpful in cultivating students' spatial imagination and logical reasoning ability.It lays a solid foundation for further study of geometric arguments.From the perspective of the research method above,this article mainly uses a variety of research methods such as literature analysis,questionnaires,tests,and interviews.This study focuses on the types of learning disabilities(cognitive impairments,mental disorders,and operational disorders)that the student learns from this chapter,after questionnaires and tests to determine the content of triangles in grade 2 and grade2 students.Based on the analysis of the obstacles,some suggestions on the teaching of the chapter are proposed.The inadequacies of this study: due to the author's own academic level,some of the theoretical perspectives are not described in depth,examples are also superficial;The self-test paper is not very good;In addition,solutions based on the types of learning disabilities do not know whether they can be implemented in practice,but also need to further improve the study.
