生物学科注重实验的教学和运用,但是限于教学时间和教学条件的不足,使得模型的运用更为普遍。在生物学教学中运用的模型,抓住了事物现象的本质,略去次要因素而形象化了、简化了描述的自然现象,突出了重点。借助模型具有形象性、代表性、可操作性等特点,可以帮助学生直观地理解和掌握相关生物学知识的本质,同时也为学生了解事物本质提供了新的探索思路和方法。 Biology focuses on experimental teaching and use, but is limited to the teaching time and teaching conditions, making the model more common. The model used in biology teaching grasps the essence of things phenomenon, ignores the secondary factors and visualizes, simplifies the description of natural phenomena, and highlights the key points. With the characteristics of the model such as vividness, representativeness and operability, it can help students to understand and grasp the essence of relevant biological knowledge intuitively, and also provide new exploration ideas and methods for students to understand the essence of things.
