The flipped classroom instructional strategy (also known as the inverted classroom) has been receiving a lot of attention。 Flipped classroom originated in Forest Park high school in the USA。 In the spring of 2007, the school chemistry teacher Jonathan Berman and Aron Sams wanted to solve the problem that students couldn't arrive on time for class because of the weather or the long way from home to school。 In order to make them keep up with the pace of the teacher in class, they started to record PowerPoint presentations and the voice of the lecturer with recording software and uploaded the video to the Internet。 (Bergmann and Sams 42-43)。来,自,优.尔:论;文*网www.chuibin.com +QQ752018766-

Shortly after, it becomes the hot topic in the global education。 The idea is that rather than taking up limited class time for an instructor to introduce a concept (often via lecture),the instructor can create a video lecture, screencast, or vodcast that teaches students the concept, freeing up valuable class time for more engaging (and often collaborative) activities typically facilitated by the instructor(Milman 85)。 It utilizes abundant information resources to achieve a new teaching mode taking students as the main body, which has changed the traditional classroom teaching mode centering on the teacher。 Under this mode, teachers and students discuss problems and share learning results in the classroom, which makes after-school self-study a main task for students。

However, almost at the same time, micro-class, as a kind of miniaturization, themed information learning resources, is also gradually known by people。 "Miniature video network curriculum" is called "small class" for short。 It is an online video resource as the main carrier of teaching。 The prototype of micro-class originated from the concept of 60-second course which was put forward by Professor Le Roy A。 Mcgrew of U。S。 Northern Ireland University (Liang 65-73)。
