化学教学中微观宏观关系与学生科学素养的形成

Microcosmic and Macroscopical Relation in Chemistry Teaching and the Formation of Students′ Scientific Literacy

化学教学中有诸如物质性质、实验现象、物质作用等宏观概念,又有诸如分子、原子、离子、质子、中子、电子等微观概念。在强调微观和宏观对立的同时,又可以将微观和宏观结合起来,从而使学生能够对微观世界和宏观世界有一个比较清楚的认识,并且通过微观和宏观的对比,加深对所学知识的理解,从而使学生在掌握知识的同时形成较强的科学素养。

During the chemistry teaching, there are many macroscopical concepts such as substantial property,experimental phenomenon, substantial interaction. And there are also many microcosmic concepts such as molecule, atom, ion, proton, neutron and electron, While the contradict of microcosm and macrocosm is emphasized, the integration of them should be presented in order to make students get a more precise understand. So students improve their scientific Literacy with the accumulation of the chemical knowledge,
