贝尔-兰开斯特制（Bell-Lancaster method），又名导生制（monitorial system）是一种流行于19世纪初的教学方法。

贝尔-兰开斯特制由两位英国教育家——安德鲁·贝尔博士（Andrew Bell，英国圣公会牧师）和约瑟夫·兰开斯特（Joseph Lancaster，公谊会教师）分别独立创行。1791年(或1792年)，贝尔在印度马德拉斯的军人孤儿学校中，开始选择导生帮助他教其他学生。因此这种方法也被称为“马德拉斯制”。1798年，他在回到英国以后，曾经出版过一本小册子《一个教育实验》介绍导生制，不过未能引起人们的关注。1798年，兰开斯特在伦敦巴勒路创办了一所学校，也自发实行了这种办法。后来，他发现贝尔的小册子，并在1803年出版了《教育的改良》，引起英国公众的关注。

The Monitorial System was an education method that became popular on a global scale during the early 19th century. This method was also known as "mutual instruction" or the "Bell-Lancaster method" after the British educators Dr Andrew Bell and Joseph Lancaster who both independently developed it. The method was based on the abler pupils being used as 'helpers' to the teacher, passing on the information they had learned to other students. The Monitorial System 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. Joseph Lancaster's motto for his method was Qui docet, discit -- "He who teaches, learns." The methodology was adopted by the Roman Catholic Church in England and Wales, and later by the National Schools System.
