初中物理学科是一门以实验为基础的自然学科,通过实验教学活动来提高全体学生的科学素养,为每个学生的全面发展提供机会,对学生正确的人生观、价值观的形成具有一定的推动作用。在多次的物理教学改革之后,越来越多的教师认识到物理实验教学的重要意义,并努力提高实验教学质量。然而实验教学特别是演示实验教学仍然是十分薄弱的环节。要改变这种状况,必须正确认识现阶段的实验教学的不足,从教师自身、学生现况入手,提高演示实验在物理教学中的地位,加强教师实验 The junior middle school physics is a natural science based on experiment. Through the experimental teaching activities, it improves the scientific literacy of all the students, provides opportunities for the all-round development of each student and promotes students’ correct outlook on life and values. effect. After many times of physics teaching reform, more and more teachers recognize the importance of physics experiment teaching and strive to improve the quality of experimental teaching. However, experiment teaching, especially demonstration experiment teaching, is still a very weak link. In order to change this situation, we must correctly understand the shortcomings of the current experimental teaching, starting from the teachers themselves and the students ’current situation, and improve the status of demonstration experiments in physics teaching and strengthen the teachers’ experiments
