| Nowadays, information technology plays an important role in most fields of modern life, which brings new chances as well as challenges for education. The combination of information technology and course teaching is a new entry point and good way for carrying out new course reform. With new education concepts wildly accepted, modern education technology is helpful for developing students’ ability to learn and explore.Trigonometric function is a key but difficult learning point for senior high school student. It is meaningful to combine Geogebra with trigonometric function as a new teaching method. It will solve the embarrassing situation that both teachers and students find it is difficult to teach and learn trigonometric function.The first part of this article discusses the necessity of combining information technology with courses, focusing on the aim, function, content and resent research in this field. Geogebra is suitable for teaching with many advantages such as free, powerful, easy to grasp and geometric diversity.The second part states the theoretical basis of this article and definition of “combination”.The third part focuses on how to combine Geogebra with trigonometric function in teaching after analyzing the present studying and teaching situation of trigonometric function in Chinese high school. It also propounds some principles and patterns of combination, taking carrying out combination teaching on arbitrary angle and trigonometric function graph as example.The fourth part is mainly about the analysis of data. And it shows that Geogebra can improve students’ interest and confidence in trigonometric function, and their ability of logic thinking and reasoning is also raised.The fifth part is about the reflection and expectation for combination courses by analyzing current problems and exploring solutions.After doing the research, I prove the Geogebra can benefit trigonometric function teaching a lot, hoping that it can be widely used. |
