I've been watching the Elgg tool for several years, but was waiting until the presentation builder was finished. This is the 29th tool that I have used to re-create my electronic portfolio. The process moved pretty smoothly. I was able to convert all URLs to weblinks. The tool allowed me to reconstruct my portfolio in less than an hour, copying the information from my ZohoWriter portfolio, where I had the URLs on the page (and the links). I easily uploaded a few graphics. All of my other artifacts are web links.
Since I prefer to have the links open a new window (and the portfolio remains open), I was able to specific each link to open in a new window. When an artifact is opened, the reader can close the window and easily return to the portfolio, rather than using the Back button. There is also no data management tool, to aggregate assessment data. Therefore, this tool would work for formative assessment (providing teacher and peer feedback on student work) but not for summative assessment.
The real advantage of Elgg is the social networking and blogging built into the system, as well as the file management system. I could not figure out how to create links to another Elgg presentation page, so I put the entire portfolio into a single presentation page. The program created a Table of Contents at the top of the page, with links to each section on the page. Very nice! It is very nice to have a presentation builder now as part of Elgg. Even if it is a very simple tool, it allows text, blog posts and files to be included on a presentation page. I would really like pages and sub pages, such as in WordPress, but at least it now has another way to present portfolio data, instead of just the reverse chronological order of the blog.
