摘要:The unprecedented expansion in professional and technological education in recent decades has not been accompanied by sufficient training teacher courses. Thousands of professional have worked in this area, without any previous debate about vocational education characteristics and its implications for teaching practice. There is a consensus about the lack of specific teacher training, particularly for those who work in technical or professional subjects. This article focuses on two fundamental challenges: the discussion about epistemology and the pedagogy underlying the technical or professional disciplines; and the necessary confrontation of changes in the world of work.
