Symbaloo to save and organize bookmarks. Shortly after that post went live I received an email from someone looking for other bookmarking tools that her students could use. Over the years I've tried a lot of bookmarking tools, the following are the ones that I recommend most often.
Diigo is a great option for bookmarking websites and sharing them with a group. You can use any of the many Diigo browser add-ons or mobile apps to bookmark websites. The Diigo bookmarking tools allow you to clip portions of a webpage, highlight portions of the page, and add notes to it while you bookmark. Adding those notes is helpful in letting your collaborators know why you saved a link. Diigo allows you to create public and private groups in which you share bookmarks. Creating a Diigo group is a good way for students to collaborate on a research task. Click here for a video on creating Diigo groups.
Padlet Mini is a slick tool collaborative bookmarking. Padlet Mini is a Chrome extension that you can use to bookmark websites. When you click the Padlet Mini extension in your browser you will be presented with the option to save to one of your existing walls (if you already have a Padlet account) or create a new Padlet wall. Padlet Mini is ideal for having students share links to interesting pages, pictures, and videos that they find about a topic that they are studying in class. Click here for a video about Padlet Mini.
A few years ago when Google announced that they were removing the list option from Google Bookmarks I started using Evernote for all of my bookmarks. The Evernote Web Clipper allows me to not only bookmark URLs but also annotate each bookmark with notes for myself about each URL that I bookmark. I also use the Evernote Web Clipper for clipping sections of webpages including text and images.
Annotary is a social bookmarking service that is similar to Diigo. By using Annotary in Chrome I can bookmark sites, highlight portions of pages, and annotate pages with sticky notes. Just like any good online bookmarking service, Annotary allows you to share bookmarks and search other peoples' shared bookmarks.
This list wouldn't be complete without mentioning Pinterest. If your school allows it and your students are old enough to have accounts, you could use Pinterest to bookmark your web findings. A better option than Pinterest for schools is eduClipper. eduClipper is a great place for teachers and students to collaborate on the creation of visual bookmark boards. Students do not need to have email addresses to use eduClipper and you can manage how your students share on eduClipper boards.
