Open classroom

An open classroom is a student-centered classroom design format which became popular in the United States in the 1970s. The idea of the open classroom was that a large group of students of varying skill levels would be in a single, large classroom with several teachers overseeing them. It is ultimately derived from the one-room schoolhouse, but sometimes expanded to include more than two hundred students in a single multi-age and multi-grade classroom. Rather than having one teacher lecture to the entire group at once, students are typically divided into different groups for each subject according to their skill level for that subject. The students then work in small groups to achieve their assigned goal. Teachers serve as both facilitators and instructors.
