Rozpowszechnianie, zachowywanie i nauczanie języka polskiego w świecie w latach 1918–2018, część III: Badania zbiorowości polonijnych, ich języka i kultury, bilingwizmu polsko-obcego oraz nauczania polszczyzny w świecie w latach 1970–2018

Part three of the paper concerning the Polish language around the world in the period 1918–2018 is dedicated to discussing academic studies analysing the process of preserving and passing on the Polish language in the countries where Polish communities have settled, dissertations on Polish-foreign bilingualism in Sweden, Brazil, Austria, Argentina, Australia, France, Germany, UK, Poland, Belarus, and Ukraine, and fi nally, studies describing teaching Polish as a foreign language, as a heritage language, and as a second language. Part one of the paper concerning the Polish language around the world in the period 1918–2018 ended with the statement that the ambitious action plans of the pre-war Polish authorities lacked the base in the form of the knowledge of the transformations of the Polish communities all over the world and aid for teaching Polish as a foreign language. Part three presents the important sociolinguistic output referring to the Polish language across the world, Polish-foreign bilingualism, and multilingualism, and fi nally, to teaching Polish as a foreign, second, and heritage language, which contributes to the fl ourishing Polish glottodidactics. There are currently no ambitious actions on the part of the state authorities addressing the evolving Polish glottodidactics, which relies on ad-hoc undertakings of university glottodidactics centres
