The Effectiveness Study Of Trigonometric Function Teaching In High School

The triangle function is the important content of the high school mathematics module, and also one of every year the university entrance exam study content, covering the choice to fill up the topic and the big question, difficulty moderate, therefore become students scoring. Although the difficulty of medium, but to a weak foundation’s student, it is still difficult to master. The triangle function content trival, more formula, relative to other content is more abstract, thus increasing the effectiveness of the classroom teaching of trigonometric function of teachers and students have positive significance. This article is divided into six parts:The first part, through the research methods of literature study introduces the historical development of the triangle function, and after the founding of the triangle function in the high school curriculum reform in the process of evolution.The second part, introduces the mathematical way of thinking in the triangle function content application and effects. Main: corresponding, mapping thought method; several form combining ideas method; transforming thought method; changes and transformation of thinking methods; to discuss the thinking methods of classification; function and equation way of thinking. The third part, according to his own teaching experience to improve the triangle function the effect of classroom teaching strategies and methods, and give the high school mathematics triangle function case design.The results of the study show that, improve the triangle function classroom teaching effectiveness, the first teachers’ professional knowledge to be solid, ready for teaching plan, and to further exchange with students, at the same time because of trigonometric function abstraction, teachers using sketchpad of triangle function module teaching, to improve students’ memory and understanding ability, the effect of classroom teaching effect.
