科学探究作为新课程提倡的一种重要学习方式,其目的主要就是让同学们在获取化学知识、解决化学问题时,能够模仿科学研究的过程,像科学家一样思考,从而掌握在新情境下探求真知的科学方法,逐步形成终身学习的意识、能力和科学态度.那么,在科学研究中,科学家是如何思考问题的呢?下面我们就从“有核原子模型”的发现谈起. 从1803年英国科学家道尔顿创立了原子学说起,在很长一段时间里人们都认为原子就像一个小得不能再小的玻璃实心球,里面是没有 Scientific inquiry is an important learning method promoted by the new curriculum. Its purpose is mainly to enable the students to imitate the scientific research process and to think like a scientist when acquiring chemical knowledge and solving chemical problems, so as to master the exploration of new knowledge. The scientific method gradually formed the awareness, ability and scientific attitude of lifelong learning. Then, in the scientific research, how do scientists think about the problem? Here we start with the discovery of the “nuclear atom model.” From the United Kingdom in 1803 Scientist Dalton founded the theory of atoms. For a long time people thought that the atom was like a small, solid glass sphere. There was no
