| The dynamic problem of mathematics in junior school has become one of the key and difficult problems in the junior school examination over the years.Because the spatial concept and logical thinking of school students are still in the initial stage of development,it is difficult for students to understand such problems in the traditional teaching of dynamic problem of mathematics.The dynamic geometry algebra Sketchpad software(GeoGebra)provides a powerful tool for junior school mathematics dynamic problem teaching because of its strong dynamic and easy operation.In this paper,after studying the mathematics curriculum standard(2011 Edition),consulting a large number of domestic and foreign documents about GeoGebra and junior school mathematics dynamic problem teaching,combined with the practical experience during the teaching practice,the relevant content of GGB assisted junior school mathematics dynamic problem teaching is studied.First of all,this study uses literature review method to sort out and analyzes the relevant research at home and abroad,so as to determine the research issues of this paper.Secondly,the main research contents of this paper are two parts: the first part studies the current situation of junior school mathematics dynamic problem teaching and learning in the form of test paper survey and interview survey,aiming to understand the current situation and reasons of junior school students’ solving dynamic problems;the second part uses GeoGebra to assist junior school mathematics dynamic problem teaching and selects cases to help junior school mathematics dynamic problem teaching Process analysis.Finally,the research found that the use of GeoGebra software to assist junior school mathematics dynamic problem teaching is helpful to help students to solve mathematical dynamic problems.The ideas of teachers using GeoGebra to assist junior school mathematics dynamic problem teaching are summarized as follows:First,apply GeoGebra to the process of problem inquiry to deepen students’ understanding of the problem;Second,apply GeoGebra to variable teaching and improve teaching efficiency;Third,demonstrate the whole movement process with GeoGebra to improve students’ ability of dynamic analysis;Fourth,apply GeoGebra to auxiliary line drawing teaching to help students make auxiliary line accurately. |
