On the one hand, the portfolio may focus predominately on learning and reflection. Such a portfolio may come to resemble a student's journal or sketchbook. On the other hand, the portfolio may be used primarily for evaluation and assessment, becoming more a documentation of achievement that a personal workspace. As Barrett notes, the former model focuses on the ePortfolio as process, while the latter contemplates the ePortfolio as product.
