稳态的概念是高中生物必修3模块的核心概念之一,而这一概念的提出又源于人体内环境的研究.理解内环境和稳态等核心概念,并围绕这些概念建立良好的知识体系则是本课时学习的重要价值之一.但由于本节内容比较抽象,而且要求同学学习本节内容之前要有生物分类、动物生理学等知识储备.因此要求把握重点的同时在学习方法上力求能有所改进,将抽象问题形象化和模型化,易于理解,益于增效.体液的成分及各种细胞外液间的内在联系是学习中的难点,解答题时如何理解并突破这一难点,我们可通过下面题例进行探讨.
The concept of steady state is one of the core concepts of the compulsory 3 modules of high school biology, and the concept is originated from the study of the environment in the human body, understand the core concepts of the internal environment and steady state, and establish a good knowledge system around these concepts It is one of the important values of learning in this lesson, but as this section is rather abstract and requires students to have knowledge of taxonomy, animal physiology and other knowledge before learning this section, it is required to grasp the key points while striving to be able to learn Has been improved, the abstract problem of visualization and modeling, easy to understand, benefit from efficiency.Human body composition and a variety of extracellular fluid in the internal link is the learning difficulties, how to understand the problem and solve this problem , We can explore the following examples.
