Perhaps we should adopt the Elizabethan school system then. All lessons were in Latin and students were punished for speaking English. 'Memorising texts and performing endlessly tedious translations of Latin phrases was the norm [...]. Creating situations of competition between pupils with an atmosphere of fear of physical punishment and humiliation was the usual approach.'[1]

Modern students might find a few exams preferable to this.
