Based On Geo Gebra's Teaching Practice Of Junior High School Function

With the advancement of science technology,the widespread dissemination and use of information technology,teaching research are also followed by the development of the times.In particularly,modern information education has a tremendous impact on mathematics education.The continuous integration and development of mathematics education and information technology has been welcomed by students and teachers,it has even become the direction of many educators.In the learning process of junior high school mathematics,the function is a crucial basic part and plays a key role in the junior high school.The learning experience of junior high school will directly influence the later mathematics learning process.According to "Basic Requirements for Teaching Mathematics in Junior High Schools in Shanghai",it is proposed to enhance junior high school students' ability in mathematics learning.In the teaching process of junior high school functions,we should pay attention to cultivating students' ability of reasoning,mathematical expression and mathematical modeling.The student's thinking mode needs a “bridge”from concrete to abstract to help students understand abstract knowledge.Dynamic mathematics software can be the "bridges" because of its visual and dynamic functions,so it is widely used in mathematics teaching.The use of GeoGebra(GGB)auxiliary software in the function teaching of junior high school is an effective way for students to understand functional knowledge.This research project is based on GGB assisted software mainly from theoretical research and practical research.In terms of theoretical research,this research first studied predecessors' research and combining the functional features of GGB,the principles of GGB-assisted junior high school function teaching based on cognitive learning theory,multi-representation theory and constructivist learning theory: Student-centered principles,students and teachers' interactive principles,practical principles and open principles.GGB-assisted junior high school function teaching strategies: information packaging strategy,time approaching strategy and consistency strategy.Then,according to these principles and strategies,the teaching design of the junior high school function teaching case is carried out.The case selects topics based on teaching difficulty and difficulty,whichare developed from four aspects: positive proportion function,inverse proportion function,primary function and quadratic function.In practical research,the teaching design is mainly applied to the teaching practice,and the “image of inverse proportion function” is selected as the case.The experiment is divided into pretest part,teaching experiment part and posttest part.Questionnaires,interviews and tests are used as the main means to assess whether the GGB auxiliary function teaching process can enhance the students' interest,understanding ability and exploring ability.The research results show that students in experimental class have higher interest in mathematics learning than students in the control class,and they have a better evaluation of understanding ability and exploring ability.Therefore,it is concluded that the GGB-assisted junior high school function teaching can improve the students' interest in learning,strengthen the students' understanding of the function knowledge,and help students improve their inquiry skills.This study attempts to effectively combine the GGB-assisted software with the function teaching of junior middle school.Hoping these accumulates cases have certain reference to the auxiliary function of junior high school teaching.
