在物理实验教学中,有的学校实验仪器不足,做不了学生分组实验,有的实验演示后,达不到应有的效果。这时,如果充分发挥投影仪的作用,可以弥补上述不足,更好地完成物理教学的任务。1 投影仪使用方便 利用投影仪教学,制片方便,设备简单,操作灵活,普及性强。投影灯片可用刻化、书写、 In physics experiment teaching, some schools lacked experimental instruments and could not do student grouping experiments. After some experiments, they failed to achieve the desired results. At this time, if you fully play the role of the projector, you can make up for the above deficiencies and better complete the task of physics teaching. 1 The projector is easy to use The projector is used for teaching, the production is convenient, the equipment is simple, the operation is flexible, and the popularity is strong. The projection lamp can be engraved, written,
