高中化学教科书中科学素养主题的定量分析   总被引:1,自引:0,他引:1  
刘一兵 《化学教育》2010,31(6):23-25,28
运用内容分析法对高中化学新、旧教科书中的科学素养主题进行分析,得出科学素养主题内容发生了较大的变化;传统高中化学教科书的编写注重知识与技能,对科学过程与方法的关注不够;新高中化学教科书的编写突出了科学过程与方法,拓展了科学、技术与社会的相互关系。  相似文献

在分析化学传统纸质教材存在品种重复、同质化严重、内容陈旧、落后、出版形式单一等问题的基础上,介绍一种纸质教材+新媒体资源的新形态教材形式,从它的产生与发展过程、教材内容和呈现形式的一体化设计以及优势等多方面进行具体阐释,最终提出化学新形态教材建设的三点思考,即数字化仅作为教材编著的手段而并非根本性目的,融合多种媒体,使其功能最大化以及给读者提供差异性服务。  相似文献

The basilisk of the pseudo-Paracelsian De natura rerum is the evil twin of the homunculus. Created from menstrual blood by artificial ectogenesis in an alchemical laboratory, the basilisk embodies the poisonous character traditionally ascribed to catamenial women, but magnified and concentrated by its mode of generation to the degree that it can kill by its glance alone. How does this remarkable thought experiment relate to other instances of the basilisk in the genuine and pseudonymous corpus of Paracelsus? The present paper outlines two primary uses which emerge repeatedly: first, in works other than De natura rerum, the basilisk is used by Paracelsus and his imitators as a means of explaining action at a distance, especially in the case of plague. Relying on a medieval association between the basilisk’s deadly gaze and the putative ability of menstruating women to damage mirrors, the genuine Paracelsus links contagious disease to the deleterious action of the female imagination. Second, because the basilisk was traditionally held to be the product of an unnatural birth, being born from an egg laid by a rooster and incubated by a toad, the Paracelsian corpus frequently invokes the monster as a model for unnatural generation in general.  相似文献
