This kind of isolation measures controls the consequences of students by separating them from their disturbing background. The key is to temporarily remove the students with disruptive behavior from the former activities, so as not to affect the normal learning of other students; the isolated students are often sent to a neutral place outside the scope of the original activities, and to a certain extent to ensure the normal realization of their right to education. This kind of isolation measures are mostly used in classroom situations, and the time should not be too long. The isolation in classroom is generally about 5 minutes, while other isolation methods are generally controlled between a quarter of an hour to an hour, which should not last too long.
