一、问题的提出高中化学《物质结构与性质》是高考化学中的选考内容,其中以“面心立方最密堆积”作为考查的载体在高考试题中经常出现,金属堆积方式的学习需要学生具有较好的抽象思维能力和空间想象能力,而在人教版教书中介绍这种最密堆积方式的篇幅不足半页,单纯的讲解既让教师教得乏味,又让学生学得无趣,以致学生只能死记硬背相关内容而没有真正理解其实质,教学效果很不理想。 First, the issue of the proposed high school chemistry, “Material structure and nature” is the content of the entrance exam chemistry, in which the “closest packed face cube” as a carrier for examination in the high exam questions often appear, metal accumulation of learning Students are required to have better abstract thinking ability and spatial imagination ability. In this edition, the most densely packed method is less than half a page. A simple explanation not only makes teachers tedious, but also makes students uninterested in learning. As a result, students can only memorize relevant contents without actually understanding their essence. The teaching results are not ideal.
