The invention discloses a classroom pattern system which comprises at least one of a massed learning device, an interactive discussion device and a meeting discussion device. Any one of the massed learning device, the interactive discussion device and the meeting discussion device can be used for lifting and lowering desktops through a crank-link mechanism. When teaching or learning activities are required to be carried out, a first desktop, or a second desktop or a third desktop is raised, so that the desktop in a classroom is no longer simplex and stationary but can be switched in different modes according to different requirements, and accordingly the problems of dogmatization, stereotype, simplification, stationary state and the like of the traditional teaching or learning can be solved.
