微课是指基于教学设计思想,使用多媒体技术在五分钟内就一个知识点进行针对性讲解的一段音频或视频。对于实验教学,微课可提供更安全、效果更显著的实验素材。微课虽然在科学教学中作用显著,但不能完全代替课堂教学,它只能是课堂教学的辅助。 Micro-class is based on the teaching design ideas, the use of multimedia technology in a matter of five minutes to explain a specific point of audio or video. For experimental teaching, micro-class can provide safer, more effective experimental material. Although the micro-class in science teaching plays a significant role, but can not completely replace the classroom teaching, it can only be an auxiliary of classroom teaching.
