本研究采用整群抽样法.在高三年级中抽取二个班级,一个为实验班,一个为对照班.执教老师都有毕业班复习经验,复习内容和时间都一致.复习前的新授课中,实验班试用教学目标分类方法(当时新课内容不是“三角”)即将教材中各知识点的学习水平分类告诉学生,使学生大致了解“六个”学习水平的层次.将复习的“三角”内容分为四个单元:(一)任意角三角函数及三角函数图象和性质.(二)三角函数式的变换.(三)反三角函数和三角方程.(四)解三角形.将每个单元的内容制订出教学目标和各单元的形成性测验题.单元复习开
In this study, the cluster sampling method was adopted.Secondary classes were selected in the third grade, one for the experimental class and one for the control class.Teaching teachers had the experience of graduating class review content and time are consistent.Repair before the new lectures, Experimental class teaching objectives classification method (when the new course content is not “Triangle ”) is about to learn the knowledge level of the teaching points in the textbook classifications tell the students to make students generally understand the level of The contents of the “triangle” are divided into four units: (a) Arbitrary angular trigonometric functions and trigonometric function images and properties. (B) Transform of trigonometric functions. (C) Inverse trigonometric functions and trigonometric equations. Triangle. Develop the content of each unit with teaching objectives and formative test questions for each unit.
