物理学是一门实验科学,演示实验和学生实验是物理教学中十分重要的环节.通过实验,可以培养学生初步掌握实验的方法和实验的技能,锻炼他们运用知识和观察事物的能力,为将来参加工农业生产和科学研究打下良好的基础.因此,教师的演示实验和学生实验对物理教学所起的重要作用是其他形式的教学活动所 Physics is an experimental science. Demonstration experiments and student experiments are very important links in physics teaching. Through experiments, students can acquire initial experimental methods and experimental skills, and exercise their ability to use knowledge and observe things for the future. Participate in industrial and agricultural production and scientific research lay a good foundation. Therefore, teachers’ demonstration experiments and student experiments play an important role in physics teaching is other forms of teaching activities.
