资源描述

14.4.4 输血与血型 输血与血型是七年级下册第四章第四节内容。 本章分为四节,教材通过前三节的介绍让学生对血液循环系统形成一个完整、清晰的认识,在此基础上,特意把与现实生活关系密切的输血与血型单独安排一节,是对新课程目标中情感态度与价值观培养目标的全方位体现,因此,本节内容在全章占有十分重要的地位。本节文字量不多,知识量也较少,但是却与人类生活有十分密切的关系。这些内容学生也很感兴趣,渴望获得相关知识的欲望也很强烈。基于此,正好鼓励、支持、学生课前通过上网等多种途径查阅、收集了解有关血型与输血的知识,并展开调查,课上交流。通过学生丰富的感性体验与深刻的感悟,来实现情感态度与价值观培养目标有效达成。
