Digital portfolios are an effective way for students to showcase evidence of meeting educational standards. Eportfolios are becoming popular again as technology has advanced. Teachers must decide which student work products best illustrate learning aligned to curriculum standards. Portfolios can progress from paper to digital formats over time, starting with simple programs for young students and advancing to web-based options for older students. Popular web-based tools include personal web pages, Pageflakes, Box.net, and Slideshare which allow sharing of files and presentations online.
