实验是初中生物课的基础,也是生物教学的一个重要组成部分。初中生的认知和理解能力虽然比小学生要强一点,但是由于生物学科的抽象性和科学性,仍然让很多学生难以理解生物知识。而生物实验是帮助学生学习知识的一种手段,在获得知识的同时,培养学生的观察和动手能力。实验在生物教学中发挥着巨大的作用。所以,教师要充分利用教学实验,对学生进行悉心指导,这样不仅可提高学生的学习兴趣,还可提高生物课堂效率。 Experiments are the basis of junior high school biology class, but also an important part of biology teaching. Although junior high school students’ ability of cognition and comprehension is better than that of primary school students, due to the abstraction and science of biology, many students still find it hard to understand biological knowledge. The biological experiment is to help students learn knowledge as a means of acquiring knowledge at the same time, develop students’ observation and ability. Experiments play a huge role in biology teaching. Therefore, teachers should make full use of teaching experiments, to provide students with careful guidance, so that not only can improve students’ interest in learning, but also improve the efficiency of biological classroom.
