杜威曾经说过:“教育就是经验的改造或者改组。”由此不难看出,经验是所有课程及其教学过程的基本构件。基本活动经验积累对于数学学习的重要性勿庸置疑,但是,在实际教学中,有些教师认为,学生只要参与了数学活动就一定会获得数学经验。似乎数学活动经验是教学过程中与生俱来的,是知识和技能的衍生品和附带品。实则非也,它绝不是学习过程的影印和叠加。基本活动经验的获得,同样需要教学中的精心设计与有效引导。 Dewey once said: “Education is the transformation or reorganization of experience.” It is not hard to see that experience is the basic building block of all curricula and their teaching processes. There is no doubt about the importance of the accumulation of basic activities for the purpose of math learning. However, in practical teaching, some teachers think that students must be able to acquire mathematical experience whenever they participate in math activities. It seems that mathematical activity experience is inherent in the teaching process and is a derivative and collateral of knowledge and skills. In reality, it is by no means a photocopy or overlay of the learning process. The acquisition of basic activities experience also requires elaborate design and effective guidance in teaching.
