The propaedeutic value of Esperanto is the effect of Esperanto in preparing students to study other foreign languages. It is believed that grasp of a different language improves one's abilities to use their first language and explore other cultures more successfully. The planned language Esperanto has been shown in several countries worldwide to be a good preparatory tool to learn other languages. Studies, such as that of Helmar Frank at the University of Paderborn and the San Marino International Academy of Sciences, have concluded that one year of Esperanto in school, which produces an ability equivalent to what the average pupil reaches with European national languages after six to seven years of study, improves the ability of the pupil to learn a target language in comparison to that of pupils who spent the entire time learning the target language.
