公开课是有组织有计划有目的的一种面向特定人群做正式的公开的课程讲授活动。每次活动要求主题鲜明、任务明确,除了学生参加听课外,一般还有领导及其他教师参加,是教师展示教学水平,交流教学经验的有益的研究活动。 An open class is an organized, purposeful program of formal public instruction for specific groups of people. Each activity requires a clear theme and a clear mission. In addition to students attending lectures, there are also leaders and other teachers participating in the lectures. It is a useful research activity for teachers to demonstrate teaching level and exchange teaching experience.
