Diigo: Chrome Extension We Love (Google-a-Day)

If a Kindle and a Kurweil 3000 had a baby, they’d make Diigo library. Diigo is one of my favorite online learning tools for middle school and high school students.

What it Does

Diigo library lets you:

  • highlight (in multiple colors)
  • add sticky notes
  • share pages
  • share notes
  • add tags
  • compile all of your notes & highlights in you “Diigo library”
  • save pages to “read later”
  • screen capture

and that’s all free (they also have Premium Features, but I’ve never felt the need to explore those since there’s so much functionality as is).

When should I use Diigo library?

All! The! Time!

It makes a very effective research tool; students can research a topic of interest (from any website), and highlight important facts, write notes about their thoughts, and compile this information in their Diigo library, which will make it easy for them to write a research paper afterwards.

To help organize notes, students an add tags or save notes to different lists.

Collaborative research is made more fun and possible through Diigo. Students can form a “Group,” then share specific notes, sets of notes, or pages with their peers. Want to mix it up and do a Jigsaw activity? That’s okay too. You can always add other students to notes (double the information!).

Any reading comprehension activity is made more engaging (and active) by using Diigo. Students can add notes with questions or predictions, use highlights for facts vs. opinions about a topic, and share notes or ideas with peers. Encourage students to use Diigo not just for strictly academic research, but for any topic of interest to them.

Cornelius Minor is big on creating a classroom library of information that’s interesting to the students then & there. Diigo is a perfect way to create shared reading activities through technology. Students can be encouraged to comment, question, or highlight interesting passages on any website.


Why I Love It

Once you download it from the Chrome Store, Diigo “lives” in your extensions (on the top right of your browser). Thereafter, any time you highlight something, the annotation tools pop up near the highlight. You can also click the icon in your toolbar and select other features.
