我们在生物学教学中常用理解、对比、简化归纳、联想等方法,使知识条理化、系统化,让学生理解透彻、记忆牢固。如我们将生物的主要特征编成的歌诀、谜语有三千多首,它们生动形象、通俗易懂、朗朗上口,既突出重点,又化难为易。现选编部分如下:1、两头尖尖相貌丑,没有脚来没有手, 长年累月地里走,施肥松土是能手。 （蚯蚓）2、小小老鼠不寻常,披上皮膜成翅膀, 白天睡觉后腿挂,夜晚捕虫声导航。
In the teaching of biology, we often use methods such as understanding, contrasting, simplifying induction, and associating, so that knowledge is organized and systematized, so that students understand thoroughly and have strong memory. For example, we have compiled more than 3,000 songs and riddles for the main characteristics of living creatures. They are vivid, easy-to-understand, and catchy. They not only highlight the key points, but also make it difficult to understand. Selected sections are as follows: 1, the two ugly face, no feet, no hands, walk for many years, fertilizing loose soil is a master. (蚯蚓 ) 2, little unusual mouse, covered with a film into the wings, hanging during the day and then hanging legs, at night to catch insects navigation.
