众所周知,我国的传统教育模式以知识积累为目标,教师仅限于传授,讲解知识,学生只限于模仿,机械式地接受知识。显然,这种“传授—接受”式的教育模式不利于创新能力的培养。因此,大力倡导教育改革,推行创新教育成为时代的最强音。作为一名数学教师,如何在课堂教学中,培养学生创新能力呢?笔者正尝试着将“头脑风暴法”这种思考方法引入数学课堂教学之中。一、提出一个具有探究性的问题师:出示教学图片,如图1,是抛物线型拱桥,当水面在CD时,拱顶离水面2m,水面宽4m。水面下降1m,水面宽度增加多少?
As we all know, the traditional education model in our country aims at accumulation of knowledge. Teachers are limited to imparting and explaining knowledge. Students are limited to imitation and accept knowledge mechanically. Obviously, this kind of “imparting-accepting” education mode is not conducive to the cultivation of innovative ability. Therefore, advocating education reform vigorously and implementing innovative education become the strongest voice of the times. As a math teacher, how to cultivate students’ creative ability in classroom teaching? The author is trying to introduce the thinking method of “brainstorming” into mathematics classroom teaching. First, put forward a question with inquiry division: Show teaching pictures, shown in Figure 1, is a parabolic arch bridge, when the water surface in the CD, the dome from the water surface 2m, the water surface width 4m. Water surface down 1m, the width of the water increase?
