Current Situation And Influencing Factors Of Junior High School Students Solving Dynamic Geometry Problems

Dynamic geometry problem,as a kind of problem to explore the change rule of geometric figure from the viewpoint of motion,involving considerable knowledge points and flexible examination questions.It has become a major difficulty for students to learn geometric knowledge,and it is also a hot issue in geometry of the curriculum standard for middle school mathematics in compulsory education,which caused a phenomenon that students feel difficult to solve the dynamic geometry problems,and the error rate is high.Therefore,it has positive practical value to research the current situation and influencing factors of junior high school students' solving dynamic geometry problems.This paper has investigated the existing circumstances about the current situation of dynamic geometry problems solved by junior middle school students,through the ways of literature research method,investigation method,interview method,etc.From the above,three important factors that influence students to solve dynamic geometry problems are obtained and it also constructed a structural equation model about these problems.Conclusion can be drawn from the above analysis:(1)Junior high school students generally believe that they are not familiar with dynamic geometry problems,and most of them are still in the advanced stage of multiple structure in SOLO theory.The problem type with the highest error rate is functional problem,and the problem type with the lowest error rate is single moving point problem.(2)When junior high school students solve the dynamic geometry problems,there are mainly the following problems: the topic involves too many knowledge points,large amount of information,unable to understand the meaning of the question;In the process of movement,the change rule of the relevant graphics was wrongly judged,and the range and mode of movement were not clear.Algebraic operation error;Can not contact the relevant knowledge points to solve the problem;Classified discussion consciousness is insufficient;Lack of associative comprehensive analysis ability.(3)Learning motivation,learning anxiety and learning strategies have significant effects on dynamic geometry level in junior high school students.Learning motivation has the largest positive influence on the dynamic geometry level of junior high school students,followed by learning strategy.However,learning anxiety has a negative impact on the dynamic geometry level of junior high school students.According to the research conclusions,the research enlightenment is obtained:(1)Dynamic geometry software is used in dynamic geometry teaching to stimulate learning motivation.(2)The teaching of dynamic geometry is permeated with mathematical ideas and methods to relieve learning anxiety.(3)Variable training is carried out in dynamic geometry teaching to optimize learning strategies.
