摘要
为了提高"大学化学实验"教学效果,在实验教学中将智能手机通过无线投屏器和投影仪连接,将实验原理讲解、实验仪器操作、纠正实验共性错误和实验安全培训等教学基元高效率地展现于课堂。该教学新模式突破了实验室空间限制,不但有助于提高指导教师的课堂时间的利用效率,而且提高了对学生的指导率和实验成绩优秀率,还培养了学生严谨的化学实验习惯。
In order to improve the teaching effect, a new teaching mode based on smart phone-wireless screencast-projector has been well designed. These teaching units such as experimental principle, experimental instrument operation, correction of common error in experimental operation and safety training have been performed with high efficiency. This new teaching mode breaks through the limitations of lab space, which not only helps teacher instruct students with high efficiency, but also makes students do chemical experiments with good scientific habits and further increase their experiment grades.
