Research On The Effectiveness Of Mathematical Proposition Teaching In Junior Middle School

Mathematical propositions are an important part of mathematics knowledge,and mathematics proposition teaching is one of the core contents of mathematics teaching.Junior high school is the initial stage for students to formally learn geometric knowledge.Classroom teaching is the main channel for students to acquire systematic geometric knowledge.Literature research shows that there are few studies on the effectiveness of mathematical geometric proposition teaching at home and abroad.There is no clear definition of the validity of geometric proposition teaching.It has been confirmed that Van Hill's level theory can accurately describe students' geometric thinking.Especially in the development of graphics.Therefore,the study of the effectiveness of mathematics geometry proposition teaching has practical and practical value for improving the quality of junior high school geometry teaching.Taking the three classes of junior high school students as the research object,through the questionnaire survey and the experimental research on the effectiveness of the junior high school geometric proposition teaching,the paper draws out the problems existing in the effectiveness of the junior high school geometric proposition teaching,and sorts out the junior high school geometric proposition teaching.The basic content explores the factors that influence the effectiveness of junior high school geometric proposition teaching.Through the pre-test and post-test of the experimental class and the control class,the relevant conclusions are drawn on the basis of data collation and analysis by SPSS and Excel software,and the feasible suggestions are provided for the students' mathematics learning and teachers' teaching.The study found that:(1)There are four main factors affecting the effectiveness of junior high school geometric proposition teaching: teachers,students,teaching environment and geometric proposition itself.(2)Improve the quality of junior high school geometry teaching,teachers must carry out geometric teaching with the support of their own teaching concepts,and realize the true meaning of geometric teaching;must strengthen the practice of geometric teaching ability,teach geometric propositions with modern educational technology,and develop students' thinking ability.(3)The intellectual training of students and the construction of geometric propositional networks are the key elements of learning geometry.Due to my own level and research conditions,there are some shortcomings in thesampling range of samples and the validity of geometric proposition teaching.Further research is needed.
