实验教学是中学物理教学的重要环节,由于受时间、空间和实验设备诸因素的影响,有的实验在课堂内根本不能演示,有的成功率低,有的可见度差等,影响着实验教学质量的提高。恰当地选择和运用电教媒体,并与传统的实验媒体结合,对于改善实验教学手段、弥补上述不足、提高实验效果具有重要的作用。
Experimental teaching is an important part of physics teaching in middle schools. Due to the influence of time, space, and experimental equipment, some experiments cannot be demonstrated in the classroom at all. Some have low success rates and some have poor visibility, affecting the quality of experimental teaching. The improvement. The proper selection and use of audio-visual education media combined with traditional experimental media plays an important role in improving experimental teaching methods, remedying the aforementioned deficiencies, and improving experimental results.
