Research On Elementary Function Teaching Practice Based On GeoGebra

In recent years,with the continuous improvement of informatization,the diversified transmission of teaching materials has become the focus of modern teaching research and practice.The informatization-based teaching mode is helpful for junior high school students to enhance their innovative consciousness,improve their practical ability,and cultivate their core qualities,such as the combination of numbers and shapes.It can also activate the classroom atmosphere and expand students’ understanding of textbook content.However,compared with traditional teaching,there are still some problems in the application of the information-based teaching mode in teaching,such as ignoring the dominant position of students and exaggerating the teaching effect.Therefore,according to the actual situation of junior high school mathematics teaching,this paper discusses the information-based teaching of junior high school function based on GeoGebra by using literature analysis,in-depth interview,questionnaire survey,case study,and so on,and obtains the strategies that are conducive to improving the efficiency of classroom teaching.The details of the research and conclusions are as follows:1.In the first and second chapters of the paper,the core concepts of function and GeoGebra and the brief history of their development at home and abroad are described.Also,the theoretical basis and teaching principles of GeoGebra-based elementary function are expounded and studied.It shows that the traditional teaching method reduced students’ participation and decreased teachers’ teaching quality.Therefore,the "chalk ＆ blackboard" teaching mode is difficult to arouse students’ interest in learning mathematical functions.2.In the third chapter,the author designs and implements the teaching case of junior high school function based on GeoGebra and makes a statistical and comparative analysis of the results before and after the implementation of the case.The results show that the teaching mode can effectively improve the function learning results of junior high school students,and there is a significant difference between the experimental class and the control class in the post-test results.3.In the fourth chapter,through the questionnaire survey and the interview analysis obtains: the GeoGebra-based elementary function teaching model constructed in this paper is effective,And it is also helpful to cultivate students’ mathematical core literacy,exercise students’ mathematical thinking ability,and improve students’ interest in mathematics learning.4.The fifth chapter puts forward the conclusions and suggestions of this study and discusses the study’s shortcomings and prospects for the follow-up study.
