生物学是一门以实验为基础的自然科学。初中生物新教材也充分体现了这一特点。然而,除了城市中学的教学设备较好,能按新教材的特点,顺利地完成实验教学外,对于大部分教学设备较差的农村中学来说是比较困难的。再加上生物不列为升学考试科目,学生不重视,家长不重视,学校领导不重视,这给生物教学带来更大的困难。然而实验教学对于激发学生的学习兴趣起着至关重要的作用,上好实验课,不仅能使学生深刻理解所学的基础知识和掌握实验技能,而且能培养和发展学生的观察能力、思维能力和创新能力,激发学生学习生物的积极性。因此,
Biology is an experiment-based natural science. Junior high school biology teaching material fully embodies this feature. However, apart from the good teaching facilities in urban secondary schools and the successful completion of experimental teaching according to the characteristics of new teaching materials, it is more difficult for most rural middle schools with poor teaching facilities. Coupled with biology is not listed as entrance exam subjects, students do not pay attention, parents do not pay attention to school leaders do not pay attention, which brings more difficulties for biology teaching. However, experimental teaching plays an important role in stimulating students ’interest in learning. A good experimental class not only enables students to profoundly understand the basic knowledge learned and experimental skills, but also cultivates and develops students’ observation ability and thinking ability And innovative ability to stimulate students to learn biological enthusiasm. therefore,
