生物学不同于语文、数学等学科，它是研究大自然中各种生物生命现象的科学。学生除了学好书本知识外，还必须通过观察、实验来验证书本知识．从中培养学生的基本技能，培养学生的观察能力和思维能力。几年来我在生物学教学中抓住生物学实验这条主线，寓“练”于教学之中，进行 Unlike biology, mathematics, and other disciplines, biology is a science that studies various biological life phenomena in nature. In addition to learning the knowledge of books, students must also verify book knowledge through observation and experimentation. From here, students’ basic skills are cultivated, and students’ observation and thinking skills are cultivated. Over the past few years, I have grasped the main line of biology experiment in biology teaching, and placed “training” in teaching.
