These are four ways that I believe that using ePortfolios from Kindergarton to grade 12 would be beneficial to students.
I also found an interesting article about the benefits of ePortfolios. What I like about it is that it talks about how ePortfolios benefit all the people involved in them: the students themselves, their teachers and potential employers. I also like that it differentiates between the benefits students, educators and employers will obtain from the actual process of making an ePortfolio and the product itself.
