高中数学三角函数是课堂教学重要模块之一,在历年高考中也属于必考内容,虽然难度适中,但是基本覆盖了填空题、选择题和大题,是学生考试重要的得分点。但是三角函数内容繁杂,相对抽象且公式较多,所以在高中数学课堂教学中,要尤为注意和几何画板相结合教学,实现三角函数有效性教学。
High school mathematics trigonometry function is one of the important modules of classroom teaching. It also belongs to compulsory content in college entrance examination over the years. Although it is moderate in difficulty, it basically covers blank-filling questions, multiple-choice questions and big questions. It is an important score point for student examinations. However, trigonometric functions are complicated, relatively abstract and have many formulas. Therefore, in high school mathematics classroom teaching, we should pay special attention to the combination of geometry drawing board and teaching to realize the effective teaching of trigonometric functions.
