Research On The Teaching Design Of Quadratic Function Based On GeoGebra

The rapid development of information technology has promoted the reform of education,and the research of educational information in various disciplines is increasing day by day.Mathematics education and information technology are also continuously integrated and developing.The mathematics curriculum standards for compulsory education published in China Points to positive development and effective utilization of all kinds of teaching resources,reasonable application of modern information technology,pay attention to the integration of information technology and curriculum content,effectively change the traditional teaching methods,improve the classroom teaching effect,the quadratic function of the teaching process,teachers should guide students to explore the quantitative relation and the change rule of specific issues,the image and the algebraic to different forms of expression of knowledge,pay attention to the spread of mathematics thought method,realizes the mathematical abstraction and intuitive imagination,it shows the importance of modern information technology and curriculum integration.This study will GeoGebra software related to the quadratic function of the integration of teaching content,based on the existing research review,combing the research background and research significance of understanding GeoGebra software and quadratic function of the related research and literature review,which found that students' learning difficulties of quadratic function and form the research question:Question 1: How to design the teaching of quadratic function in junior high school with GeoGebra software as the platform?Question 2: Is quadratic function teaching based on GeoGebra software better than traditional teaching design? At what stage do you teach students better?Based on the above problems,the research scheme is designed.Firstly,the GeoGebra software is basically introduced,its advantages are explained,its feasibility is analyzed and the theoretical basis of this paper is provided;Secondly,through the interview test method to understand the learning function of two parallel classes in a school,according to the actual situation of learning,using the TPACK framework based on the multiple representation theory of instructional design model to provide an operational instructional design;Finally,the teaching practice is carried out to analyze the influence of GeoGebra software on the transformation thought of students in the teaching of quadratic function by analyzing the homogeneity analysis of the research object before the experiment,the post-test and after-class interview.Results and conclusions:(1)GeoGebra based quadratic function teaching designQuadratic function possesses the characteristics of abstractness,transformation,adaptation and grade students of quadratic function of dialectical thinking ability,text and graphics information conversion ability is weak,so based on the TPACK framework design of teaching mode,multiple representation theory provides the operable teaching design,resulting from the analysis of the following strategies:(1)information packaging strategy;(2)unity strategy;(3)Synchronization strategy;(4)diversification strategy.(2)Practical effect of GeoGebra based quadratic function teaching design(1)GeoGebra software is a teacher-student communication platform that can be widely used in mathematics classroom;(2)The teaching design based on GeoGebra software has a better teaching effect than the traditional teaching design.The use of GeoGebra software can have a great impact on students' learning,and improve students' interest in learning,combination of numbers and shapes,transformation,application consciousness and other mathematical thoughts;(3)The information-based teaching design based on teacher demonstration is more suitable for the teaching process of middle school students.
