当前,以网络为媒介的云技术、虚拟实验、翻转课堂、幕课、微课、微视频、微电影等正改变着现实的物理课堂教学。为此,笔者将传统教学手段与云技术相结合,以改进物理课堂教学,取得了较好效果。一、实时传输与同步播放中的师生多元互动为了掌握学情,教师经常请几个学生到黑板上做题或以投影手段向学生展示解题过程,这种互动形式存在选择范围小、形式单一的缺陷。而在WIFI Currently, web-based cloud technologies, virtual experiments, flip classes, curtain classes, micro-class, micro-video, micro-movies are changing the reality of the physical classroom teaching. To this end, the author combines the traditional teaching methods and cloud technology to improve the physical classroom teaching, and achieved good results. First, the real-time transmission and synchronization of multiple interactive teacher-student interaction In order to master the learning situation, teachers often ask a few students to do the problem on the blackboard or by projection to show students the problem-solving process, this interactive form of choice there is a small range of forms Single defect.
