Every year, thanks to the Erasmus programme, thousands of students in Europe make part of their studies in another country using a second language (L2) they know with a proficiency level B1/B2. A path to facilitate a successful mobility exchange, as well as students' inclusion in a multicultural and multilingual environment through innovative learning and teaching practices offering educational models to modernize and internationalize the higher education system, and to place European training experiences on the global training scene through Massive Open Online Courses (MOOCs) are some of the main priorities of the LMOOC4Slav - Romance Languages for Slavic-speaking University Students, an Erasmus+ funded project (2021-1-IT02-KA220-HED-000027501). Although not exclusively, its primary target audience consists of university students, mainly with Slavic languages as their mother tongue (L1), learning Romance languages, specifically Italian and Portuguese, who intend to do a mobility period at a university in Portugal or Italy, and also native Slavicspeaking teachers who teach Portuguese and Italian as L2 to those students. The project centres around the production of two Language MOOCS (LMOOCs), one for Italian and the other for Portuguese, organised in six modules. The aim is to promote students' development of linguistic fluency in academic contexts and access to authentic academic situations and learning tools to enhance their ability to learn how to learn. It also focuses on developing a repertoire of Open Educational Resources (OERs) intended for Slavic language teachers and students of Portuguese and Italian as L2. These resources will allow their reuse in different learning environments, guided by an online pedagogical guide for integrating LMOOCs and OERs. The project outputs will remain available in an open-source repository after its end ensuring its sustainability.
