Abstract


Conic is heavy and difficult for high school mathematics teaching, it is a concentrated expression of the basic idea of ??analytic geometry, and the the DGS technology is a mathematical-based computer tools, it is a good show geometric dynamic generation process, to make the students understand geometric phenomenon and found that the laws of geometry, but the current technology platform not well applied in secondary school teaching. In this study, from the three aspects of the teaching objectives, teaching process, teaching effectiveness Analysis of the impact of the DGS technology on the teaching of conic. The unit teaching \method - experimental study. Before the beginning of the experiment, the departure from the concept of the new curriculum, the status quo of the status and conic home and abroad in recent years, DGS technology integration and Middle School Mathematics Teaching. To provide theoretical support to the conclusion of the study, in-depth study on the DGS technology and conic teaching: three aspects of constructivism, the value of mathematics education, teaching geometry characteristics analysis the DGS technology is no longer complementary tools of mathematics education , but part of the mathematics teaching; from the perspectives of the conic teaching requirements and teaching characteristics. On the experimental side, I used the single factor level group quasi-experimental research methods, to 40 students in the Sanya City, the first secondary school senior grade two classes (experimental class, compared to classes) were tested object, a one-month experimental study. Irrelevant variables in the process of experimental research, in accordance with the relevant theory has been effectively controlled, the real experimental data and the test data matching sample T-test using SPSS 15.0 statistical software, a comprehensive survey of students, the teachers interviews and other material, this study the following conclusions: DGS technology conic teaching can not be done well the knowledge teaching objectives, but have a good upgrade on the ability to target and emotional goals; in the teaching process, teachers became the guide of the students, collaborators, students became the subject of the classroom, the development of capacity and awareness of self-exploration; However, using DGS technical teaching, compared with the conventional teaching, teaching effect is obvious, popular teacher students welcome. \Perhaps it is due to lack of preparation, experimental period is too short and other factors, this teaching method is not unit test scores of students Oval knowledge \But I think that as long as the long-term adherence to such the DGS technology as a platform for teaching methods, will make the students' mathematical thinking has been greatly improved.
