Cognition and process vs. design artifact in fashion design pedagogy

Design education is changing as a result of an expanding body of research into, by, and through design. Fashion design process is only just starting to be recorded, documented and validated as a legitimate design discipline with its own knowledge structures. Fashion design studio no longer focuses on the creation of a design artifact, but uses a design pedagogy that emphasizes the design process and cognition through open-ended learning tasks. What are the epistemological issues at the core of fashion design - where a major part of design process is an understanding of the relationship between flat pattern and form, and the intimacy of the human body? How do we educate a student in 'designerly thinking', and how does the cognitive content of design thinking become a reality in contemporary fashion design education?
