Dipity is a new web application for creating online timelines. It’s accessible to English Language Learners, but you can find others that are easier by going to Student Timelines on my website.

However, it does have one feature that makes it stand apart from the others — you can let others have access to edit it.  Because of this feature, I’m going to add it to The Best Online Tools For Collaboration — NOT In Real Time.

It would be a nice tool to use with our Sister Classes project.  I could imagine, for example, my students creating a timeline covering a period of history in the United States and then one or more of our sister classes in other parts of the world adding what was going on in their country at the same time.
