The Zagreb method is an Esperanto teaching method that was developed in the city of Zagreb in the late 1970s to early 1980s as a response to the unsatisfactory learning outcomes of traditional natural-language teaching techniques when used for Esperanto. Its goal was to streamline the material in order to equip learners with practical knowledge that could be put to use in as short a time frame as possible. It is now implemented and available on some of the well-known learning websites in the community.[citation needed]
