The quality and content of English language courses offered in secondary schools require special attention as they affect many students who learn English as one of their school subjects. Despite curricular provisions prescribing balanced development of language competence and a number of so-called “key competences”, class work in Polish upper-secondary schools heavily focuses on developing students’ selected language skills and language systems, i.e. the areas that are tested during school-exit exams, neglecting civic competences (i.e. group work) and digital skills. It is suggested that technology-assisted project-based language learning can help remedy this situation. Accordingly, the aim of this article is to outline a class project that illustrates the integration of project-based learning approach in language (English) and content (Polish language and culture) learning, the execution of which necessitates collaboration in groups, as well as the use of technology. It is hoped that the presented project will provide inspiration and guidance on how to engage upper-secondary school students in meaningful project work so that the development of target competences can be facilitated.
