从新《课程》开始实行后,各校都根据要求开设了研究性学习类型的课程,但由于这一课程的特殊性、新颖性,学校和教师都处在摸索阶段,据了解具体开展研究性学习时,有的教师对研究学习的认识模糊、有偏差,对如何开展研究学习心中无数,下面我就“三角形内角和”一课的教学谈一谈对研究性学习的一些看法。1、教学简要过程1.1问题的提出(1)叙述平角的定义(2)演示如图1-1,设三角形的三个内角为α,β,γ,将三角形的顶点A置于O点,角的两边靠紧,要求学生观察OB,OC是否在一条直线上?
Since the introduction of the new “Courses”, all schools have set up research-based learning courses upon request. However, due to the particularity and novelty of this course, schools and teachers are all at a groping stage.

Here I will talk about some of the views on research-based learning in the teaching of “The Teaching of Triangulation and Triangle.” 1, the teaching of a brief process 1.1 problems (1) the definition of flat angle (2) Demonstration shown in Figure 1-1, set the three internal angles of the triangle α, β, γ, the vertex A of the triangle at O point Both sides of the tight, requiring students to observe OB, OC is in a straight line?
