遗传学和变异学是高中生物教学的重点和难点,其具有一般生物知识所不具备的较强的逻辑性和抽象性,加之其知识点较多、知识结构复杂、知识点之间联系紧密等特点,使得学生在这部分生物知识的学习过程中感觉较为吃力。遗传学和变异学相关知识是高考生物中考查的重点内容,帮助学生学扎实、学透彻这部分内容是十分重要的。本文从高中生物遗传学和变异学相关知识出发,结合到教学实际,对如何学好高中生物的难点遗传学和变异学进行探究。
Genetics and variation are the key and difficult point of high school biology teaching. They have the strong logic and abstraction not found in general biological knowledge. In addition, their knowledge point is more, the knowledge structure is complex and the knowledge points are closely linked Characteristics, making students feel more difficult in this part of the biological knowledge learning process. Genetics and mutation-related knowledge is the key content of the examination of college entrance examination to help students learn solid, thoroughly understand this part of the content is very important. Based on the knowledge of high school biology genetics and mutation, combined with the teaching practice, this article explores how to learn the difficult genetics and mutation of high school biology.
