Research On Teaching Practice Of The Problem Of Moving Point In Junior Middle School Mathematics

The problem of moving point in junior mathematics not only synthesizes the basic knowledge and skills of mathematics in junior middle school,but also examine of students' ability to apply knowledge and skills as well as the ability to deal with practical problems.However,the students' mastery is not very good,students are not good at solving moving point problems,the teaching effect of teachers is not very ideal,there is no specific effective teaching method to guide teaching.Therefore,the author focused on the problem of moving point in junior middle school mathematics,from the angle of students' problem solving and teachers' teaching practice,classified the problem of moving point,and according to the classification,gave students' strategy of solving problems and teachers' teaching countermeasures,and applies them to practice.The first part of this paper introduces the research background,research status,and definition of the moving point in junior middle school mathematics,and puts forward the problems to be studied.Aiming at the research problem,the author described the research methods and innovation points applied in this paper.The second part of the thesis describes the theoretical support of the moving point problem in junior high school mathematics.Among them,the author analyzed the psychological process of the learner,the general principles of optimizing teaching design,and how teachers can teach mathematics better in practice teaching,how to systematically teaching geometry knowledge,and how to break through geometric difficulties.The third and fourth part of the thesis is mainly about the classification of the moving point problem.For the single moving point problem,the author chose the classical examples in the recent years,according to the moving point of the moving background of the classification and analysis.Aiming at the students,the author analyzed the problem solution strategy,including the question mentality and the answer analysis;for teachers,the author analyzed the types of each category,and gave the corresponding teaching countermeasures.The key to the problem of the double moving point is the normalization.The author focused on the strategy of normalization,and described how to reduce the variable and the difficulty of the problem.Corresponding to the single moving point problem,the author gave the corresponding double or multi-moving point problem and carried on the teaching research.The fifth part of the thesis stated how to apply the teaching strategy of the moving point problem into practice.In this paper,a case study is conducted to intercept the single moving point problem and the partial fragment of the double moving point problem.Practice has proved that the new teaching methods have a positive impact on students,and also put forward some practical teaching suggestions for teachers.The sixth part of the thesis makes a brief summary of the thesis,and puts forward the prospect and deficiency of the thesis.
