在平时的教学工作中,我发现那些易于让学生理解的科学现象大多都是能摆在面前让它们或看得见;或摸得着;或听得到的。简单的说,处于科学启蒙阶段的孩子们的科学理解还只是建立在经典物理学的范围之内而已,如物体之间的动与静,这是看得见的;热的传递是摸得着的;声音的产生与传播,这是听得到的。那么,怎样才能让学生们理解那宏观世界的神奇呢?我想,模拟实验和建立模型的善加利用是必不可少的。以五年级上册科学课本为例,其中第一单元
In my usual teaching work, I found that most of the scientific phenomena that are easy to be understood by students can be placed in front of them or seen or touched or heard. Simply put, the scientific understanding of the children in the scientific enlightenment stage is only built within the scope of classical physics, such as the dynamic and static objects, which is visible; the heat transfer is tangible The sound generation and transmission, which is audible. So how do you get the students to understand the magic of the macrocosm? I think it is essential to make the best use of simulation experiments and model building.
