Analysis And Solution To The Problem Of Mathematical Dynamic Geometry

China is implementing a new curriculum reform of basic education,junior high school compulsory curriculum standards(2011)that the development of dynamic geometric thinking requirements for students to change,attracted widespread attention.Dynamic geometry problem is the senior high school students to examine the importance of mathematical quality But the author in the education process that the dynamic geometry problem is the difficulty of learning junior high school students in solving dynamic geometry problems in a lot of mistakes.Therefore,the study of junior high school students to solve the problem of dynamic geometry obstacles and countermeasures for improving teaching Provide the reference basis,has the important practical significance.This study used a variety of research methods such as test,questionnaire,interview and literature analysis.First of all,through the analysis of teaching materials and teaching inductive mathematics in recent years in the examination of the dynamic geometry,its classification and finishing the following four basic types of topics: jog problem,linear motion problem,graph dynamic problem and function type moving point problem.The survey tools used in this study are self-made questionnaire and test questionnaire(see appendix).A sample of 482 third-year students in Suzhou Industrial Park was selected for testing.The results were tested and interviewed by students Situation statistical analysis and attribution analysis of students to solve problems.The test results show that there are six typical errors in the dynamic geometry problem:(1)Lack of reading comprehension.(2)The lack of use of digital combination of the problem-solving awareness.(3)The lack of the ability to use classification discussions.(4)Poor computing power.(5)Will not be auxiliary lines.(6)Lack of drawing ability.The corresponding solution is: in the teaching of teachers,to emphasize the importance of the combination of figures and ideas,and consciously in the classroom to guide students to use mathematical combination to solve problems;attention to drawing ability and increase the training of drawing.To strengthen the understanding of the basic formulas,concepts,theorem,to develop good reading habits;finishing junior high school mathematics classifications contained in the thinking of the points of knowledge and to be trained;to strengthen the calculation problem,the basis of the title of the training;Common geometric figures of the auxiliary line practices are summarized.
