课堂是学生的,学生是数学学习的主人。我们应该把它还给学生,让课堂充满生机。走进课堂,我们常常会有种说不清楚的感觉。细想现在的数学课堂总觉得还缺少点什么。一、缺乏探究性学习“三角形的内角和”这一内容时,一部分教师安排学生经历量、撕、折等一系列动手操作活动,从而得出“三角形的内角和是180°”这一结论。显而易见,这种表面上看学生 Classroom is student, student is master of math learning. We should give it back to students to make the class full of life. Into the classroom, we often have a kind of unclear feeling. Think about the math class now always feel something missing. First, the lack of exploratory learning When the content of “the inner corner of the triangle and ”, part of the teacher arranges a series of hands-on activities such as experiencing, tearing and folding of the student, thereby obtaining “the inner angle of the triangle is 180 °” This conclusion. Obviously, this seemingly students
