At the ePortfolio Conference 2008 in Waterloo, Ontario, Canada, which took place July 7-8, Julie Owen and Darren Cambridge from George Mason University presented the first draft for a typology of evidence in e-portfolios. This was in itself very interesting, but what struck me as especially interesting was that Darren Cambridge in his presentation treated the e-portfolio as a sentence: I (the user) show this competence (the reflections) supported by this evidence. The e-portfolio is in this sense not only a sentence, but a statement. If the e-portfolio can be seen as a statement, then this statement is rhetorical in nature. The e-portfolio owner is trying to convince (or persuade) his or her reader that he or she owns the competences the e-portfolio presents. But the students need to embrace this nature of persuasion. They need to feel the urge to convince. So implementing e-portfolios is to a large extent a question of creating circumstances, in which the students will experience this need. This is the main point of the article I have written for the DREAM conference “Digital Content Creation” which took place September 18-20 in Odense, Denmark this year.
