What is Techno-Pedagogical Knowledge

University instructors' technological-pedagogical knowledge receives much attention in the current professional discourse. This chapter introduces a case study based on a workshop series organised by the members of the language pedagogy department of a Hungarian university for the technological-pedagogical development of the instructors owing to COVID-19-triggered emergency remote teaching. Ten participants took part in the workshops and the study, including the two researcher-participants. Through semi-structured interviews, triangulated with field notes and personal communication, it was found that the members of the department welcomed the workshop series, especially because it was tailored to their needs. The first remote teaching period posed many challenges, but because of the workshops, the instructors felt more secure to experiment with online teaching possibilities and were able to teach higher quality lessons. Participants also reported that the workshop series resulted in feeling a sense of community and that its affordances broadened their technological-pedagogical repertoire.
