Monitorial System

The Bell-Lancaster method, named after the British educators Dr Andrew Bell and Joseph Lancaster who both independently developed it, was an education method that became popular at a global scale during the early 19th century. The method was based on the abler pupils being used as 'helpers' to the teacher, passing on the information they learn to other students. The method is now commonly known as peer tutoring.

The Bell-Lancaster method was found very useful by 19th-century educators, as it proved to be a cheap way of making primary education more inclusive, thus making it possible to increase the average class size. The methodology was adopted by the Catholic Church in England, and later the UK government as it created the National Schools System.
