Multimedia Classroom

A recording classroom is a classroom equipped with a recording system, or a classroom used for on-site recording and broadcasting of classroom teaching or lecture materials. A recorded classroom is a place where everything in the classroom can be recorded, including the actions of both learners and instructors. With the development of the national "boutique curriculum" construction project and the continuous updating and development of new technologies such as computer multimedia techn
