基于微视频的卫生化学实验教学改革与实践

Reform and practice of sanitary chemical experimental teaching based on micro-video

为解决卫生化学实验学时少、实验项目内容陈旧落伍、学生动手机会不足等问题,设计了借助微视频的实验教学模式。在调研疾控中心常规理化检验项目基础上,根据卫生化学教学需求,优选实验项目。根据教学需求,从实验基本原理、项目演示2个方面,进行实验教学微视频的设计与制作。满足了学生个性化和差异化学习需求,有助于翻转课堂教学模式的实施,提高了教学效果。

In order to solve the problems such as a fewer teaching hours of the sanitary chemical experiment,outdated experimental contents,lack of practical opportunities for students,etc.,the experimental teaching mode based on the micro-video is designed.On the basis of investigating the routine physical and chemical test items of Center for Disease Prevention and Control,and according to the teaching requirements of the sanitary chemical teaching,the experimental items are selected.In accordance with the teaching requirements,and from the two aspects of the experimental basic principle and project demonstration,the design and development of the micro-video for the experimental teaching are carried out,which meets the students＇ personalized and differentiated learning needs,and helps to implement the teaching mode of the flipped classroom and improve the teaching effect.
