生物学是一门实验学科。通过实验,能使学生加深对所学知识的理解和掌握,并培养他们实验技能。但生物实验有别于物理、化学实验。生物实验的材料是植物、动物或人体的某些部分。用活蹦乱跳的动物做实验,学生既高兴又害怕,再加上班上学生人数多,仪器、材料和用具少。如果管理不好,就可能会形成做的做、玩的玩,教师顾此失彼。
Biology is an experimental discipline. Through experiments, students can deepen their understanding of and understanding of what they have learned, and develop their experimental skills. However, biological experiments are different from physical and chemical experiments. The materials for biological experiments are parts of plants, animals, or humans. Experimenting with animals that are alive and kicking, students are both happy and afraid. Plus, there are many students in the class, and there are few instruments, materials, and utensils. If the management is not good, it may lead to the formation of playing and playing, and the teachers will miss out.
