物理教学是一门以实验为基础的学科,它贯穿于整个物理教学的始终,传统的演示实验,实验的操作主体是教师,处于实验的主导地位,学生的主要任务是对实验现象进行观察和思考,处于实验的被动地位.学生难以亲自感受演示实验真谛,也就难以帮助学生真正理解概念、掌握规律、提高能力.成功的演示实验,不仅能加强师生间的互动,提高课堂教学效率,还能有效地帮助学生获得科学探究的真实体验,养成严谨务实的科学态度,逐步培养学生的创新意识和探究能力.
Physics teaching is an experiment-based discipline, which runs through the entire physics teaching, the traditional demonstration experiment, the main operation of the experiment is the teacher, in the dominant position of the experiment, the main task of the students is to observe the experimental phenomena and Thinking, in a passive position in the experiment.It is difficult for students to experience the true meaning of demonstration experiment, it is difficult to help students to truly understand the concept, to grasp the law and improve their ability.Successful demonstration experiments, not only can strengthen the interaction between teachers and students to improve classroom teaching efficiency, But also effectively help students to gain the true experience of scientific inquiry, develop a rigorous and pragmatic scientific attitude and gradually cultivate students’ innovative awareness and exploring ability.
