备好课是上好课的前提,如何提高备课的效率和质量,这始终是教师教学工作中的主要课题。近年来,我运用目标教学理论指导备课,收到了良好的效果。下面以高中生物课本（必修）中“矿质代谢”一节为例,谈谈一些做法。 一、列举知识点 课本中每一节（或小节）都包括若干个知识要点（即课文中的黑字标题）,而每一知识重点又是由或多或少的具体知识点构成的。在备课时,首先应把每一节课中有关的知识要点或具体知识点列举出来,尤其要注意隐含知识点的发掘。“矿质代谢”一小节中的知识要点及具体知识点见附表。 Preparing a class is a prerequisite for a good class. How to improve the efficiency and quality of lesson preparation is always a major topic in teacher teaching. In recent years, I have used the target teaching theory to guide lesson preparation and received good results. Let’s talk about some practices in the section “Mineral Metabolism” in the high school biology textbook (required). I. Enumerating Knowledge Points Each section (or section) of a textbook contains several points of knowledge (ie, black headings in the text). Each knowledge point consists of more or less specific knowledge points. When preparing lessons, you should first enumerate the relevant knowledge points or specific knowledge points in each lesson, with particular attention to the discovery of hidden knowledge points. The key points and specific knowledge points in the section “Mineral Metabolism” can be found in the attached table.
