Research On The Combination Of Van Hiele Theory And Duval Theory In Information Technology Environment

As an important part of mathematics teaching,geometric teaching plays an important role in the process of mathematics learning,with the aid of geometric intuition,developing the logical thinking ability and spatial imagination.With the rapid development of the information age,information technology has gradually become the necessary means of life in education,education and teaching activities is particularly prominent.The new curriculum reform to promote,so that people are more aware of the use of information technology for the importance of geometric teaching,to fully mobilize the enthusiasm of students to learn,reflects the practical significance of the new concept.In this paper,the geometric teaching process is designed under the guidance of Van Hiele theory and Duval theory,and the geometric teaching process is designed in the information technology environment.Based on the relevant literatures at home and abroad,based on Van Hiele theory and Duval theory,the feasibility of applying it to the mathematics classroom of middle school in China is analyzed from the characteristics of geography.In the Van Hiele theory,the five kinds of teaching methods correspond to the activities of the teachers in the classroom.The four understandings in the Duval theory correspond to the goal understanding of the students in the classroom,combining the two theories and combining the characteristics of the two theories Advantages,design fusion Van Hiele theory and Duval theory of geometric teaching model,and strive to explore suitable for middle school geometric learning method.Taking the position of the high school circle and the circle and the sine function and its nature as an example,the whole teaching process is designed,the practice is carried out in high school,and the test volume based on Van Hiele theory is written to test the students' geometric thinking level.This paper based on the theory study,literature research,case method,interview method for study.It is found that the model can help students to understand the geometry to a certain extent,promote the development of students' geometric thinking level and help students to improve their math scores.However,because the study is the initial integration of the two theories,in the course of practice,found that a part of the two theories can not be coordinated,the two kinds of theoretical integration is not enough,lack of relevance,therefore,the model in our teaching Still need further experiments and improve,better promote geometric teaching.
