“…Ad (2), another strand of research, which is well developed in the German-speaking literature, examines the professional identity of pre-service/in-service teachers through biographical-narrative interviews (Georgi et al, 2011; Mantel, 2017, 2021 for Switzerland), in-depth expert interviews (Rotter, 2014b), semi-structured interviews (Bressler and Rotter, 2017), focus groups (Lengyel and Rosen, 2012, 2015) and the document analysis of teacher portfolios (Lengyel and Rosen, 2015; Rosen, 2015a).
