Straight Lines And Flat Teaching Of Computer-aided Space

At present, with computer as a core, the development of the information technology has had a profound effect on the human society. And under the promotion of a lot of people in the field of education, the research and practice of the computer assistance teaching have got unpretending development. In the days of emphasizing all-around education, in the field of teaching mathematics, there arises a new problem worth exploring on how to adjust to the development of the information age and how to use computer to assist teaching mathematics.The purpose of this essay is to analyses the computer assisted mathematics teaching in high schools; together with the teaching practice, to explore some scientific teaching principles, strategies and modes; to free computers from being as "an electric blackboard" and to give the students a surrounding and some chances to explore and solve the problems by themselves.The teaching of mathematics assisted by computers involves every aspect of mathematics and this article is trying to expatiate the teaching and methods of it by investigating and analyzing the current situation of computer assisting space, line and flat teaching. The author has analyzed the development of the computer-assisted mathematics teaching in the city of Qingdao and the result shows that though most educators use computer as an assistant to teaching, the transmission of knowledge still mainly depends on teachers, but changes by using computers. Students, as the core of teaching and learning activities, are still in a passive position, which is not good for training students as creative people and developing their abilities.In response to the above situation and considering the practical problems the students often have while studying, the author has put forward a new method of computer assisting line, space and flat teaching--- to let the students explore and operate in the course of teaching. And the principles are as follows:First, there should be actual effects and the development should be comprehensive. Students should be given enough chances to study and explore by themselves. Second, teachers should make reasonable class arrangement and use the multimedia properly. At the same time, they should play the roles of a designer, a guide and a valuator well.There are also some specific strategies:First, teachers should study the textbooks and design the lessons carefully and try to work out the main structure and strategy of the teaching.Second, the design of the lessons should focus on providing a multimedia environment for the simulating training.Third, while designing the lessons, teachers should show the content in different ways and combine them properly.Fourth, teachers should use the internet to help teach; respect the difference of levels among the students and satisfy different needs.Fifth, teachers should try to provide students more opportunities to practice in class.There are also some modes in computer assisting line, space and flat teaching: teacher's demonstration; interactive study; teaching by internet; individual tutorship and module and multidimensional teaching.After studying the theories of computer assisting line, space and flat teaching, the author made some related trials in the two classes she taught for a semester. The result shows that students who explored and operated during the teaching and studying courses have made much greater progress in studying mathematics than those who mainly followed the teachers' instructions and their abilities of analyzing and solving problems have been greatly improved. This helps prove that the author's new method is of high value in teaching mathematics.Of course, we should notice that the multimedia, as a tool in teaching, has limited functions as well as the other medias. It's not better than others in every aspect. We shouldn't regard it as an all-purpose tool or skill. Instead, we should also pay attention to the study and use of other medias in teaching.
