常见多媒体技术(PPT)在给课堂教学带来便捷的同时,也暴露出一些不足之处。如:教学中教师无法对教学媒体随时随地的控制和修改,只能按事先制作好的课件进行讲授和演示;也无法像传统教学那样边讲解、边板书、边标注。此外,在教学过程中教师还要忙碌于多媒体平台与黑板之间转换,导致没有充足时间进行师生情感的交流和沟通。因此,课堂面授教学的信息化需要特殊的综合技术,交互式电子白板提供解决方案,并很快发展成为课堂信息化教学的主流技术。
Common multimedia technology (PPT) to bring convenience to classroom teaching at the same time, but also exposed some shortcomings. Such as: teaching teachers can not control the teaching media anytime, anywhere and modify only by pre-made courseware to teach and demonstrate; also can not explain as the traditional teaching side, side of the book, side marked. In addition, during the teaching process, teachers are also busy converting multimedia platforms and blackboards, resulting in insufficient time for teachers and students to exchange and communicate their emotions. Therefore, the classroom teaching of face-to-face teaching requires special comprehensive technology, interactive whiteboard to provide solutions, and soon developed into the classroom information technology mainstream.
