The Lesson Study in Future Teacher Education (LIFT) project aims to develop a European blueprint for the professional development approach Lesson Study (LS) to support pre-service teachers (PSTs) and their teacher educators (TEs) in Initial Teacher Education (ITE). Six European countries (Netherlands, Ireland, Estonia, Cyprus, Portugal, Switzerland) will localise the blueprint in 14 ITE programmes. An online LS platform is created to connect educators and researchers across countries.
