例子是教科书中的重要组成部分。在高中《生物》(甲种本)中,主要例证有165个。约占全书总字数的1/3。这些例子大致可分为六种类型:1.生物概念(64例);2.生理功能(36例);3.生产实践(23例);4.生态系统(16例);5.生物进化(5例);6.其他(21例)。正确举例有助于增强教学效果 1.帮助学生对基础知识的理解。如讲“遗传和变异”时,让学生开展搜集家族、亲友、邻居遗传事例活动,经整理公布于众。要求学生运用所学遗传理论进行解释。以例证文,以文解
Examples are an important part of textbooks. In the high school Biology (A), there are 165 main examples. About 1/3 of the total number of words in the book. These examples can be broadly divided into six types: 1. Biological concepts (64 cases); 2. Physiological functions (36 cases); 3. Production practices (23 cases); 4. Ecosystems (16 cases); (5 cases); 6 others (21 cases). Correct examples help to enhance teaching effectiveness 1. To help students understand the basics.
