With the coming of the Internet plus Era,the integration of information technology and teaching has become an inevitable trend in the development of information technology and an important decision to promote the innovation and reform of education.Mathematical information technology has been a useful tool to improve students’learning.Linglong sketchpad has been a platform which realize mathematics knowledge and thinking visualization in the education technology of modern mathematics.In the new curriculum reform,classroom teaching becomes more open and free,and there is a lot of uncertainties in the teaching process,which tests the ability of teachers to control the class.Effective integration of information technology and mathematics teaching is a feasible approach to solve this problem.As a mathematics teaching software,Linglong sketchpad is quite practical,flexible and dynamic,when we combine its"vitality,intuition and interestingness"with the field of mathematics teaching,it can realize the way of"teaching and learning"which teachers as the leading factor and students as the main body of"autonomous,inquiry,cooperation,exchange""so that it can improve the effectiveness of teaching.Taking the image and teaching of quadratic function as an example,this paper tries to explore the effectiveness of the teaching of Linglong sketchpad in secondary school.This study begins with two aspects:theoretical research and experimental research.In terms of theory,first,the study summarize the characteristics and function of Linglong sketchpad.Second,this study discusses the principle of designing Linglong sketch boards on the basis of multiple representation theory.They are principle of information package,principle of space proximity,principle of time approaching,principle of consistency,principle of dual channel.Finally,formulating the teaching strategies according to the principles.Meanwhile,in the aspect of experimental research,we’re mainly focus on applying the sketch boards to teaching practice.Mainly based on the teaching experiment,as well as taking questionnaire survey and individual interview as the supplements,we explore the influence of Linglong sketchpad on the students’math achievement and the mathematics learning process in the auxiliary function y=a(x-h)~2+k.The study shows that the experimental class student’s mathematics study result has not been significantly improved,the students have improved their ability of understanding problems,solving problems,emotional attitude,learning methods,thinking level during the process of learning mathematics. |
