Yancey, Kathleen Blake. "Postmodernism, Palimpsest, and Portfolios: Theoretical Issues in the Representation of Student Work." CCC. 55.4 (2004): 738-761.
What we ask students to do is who we ask them to be. With this as a defining proposition, I make three claims: (1) print portfolios offer fundamentally different intellectual and affective opportunities than electronic portfolios do; (2) looking at some student portfolios in both media begins to tell us something about what intellectual work is possible within a portfolio; and (3) assuming that each portfolio is itself a composition, we need to consider which kind of portfolio-as-composition we want to invite from students, and why.
