Read Write Think offers a bunch of great web, iOS, and Android applications for students. One of those that I recently learned about from David Kapuler is Read Write Think's Timeline creator. RWT Timline is available as a web app (Flash required), as an Android app, and as an iPad app. All three versions make it easy for students to create timelines for any series of events.
To create a timeline with RWT Timeline students first tap or click along a blank line to add an event. Events can include dates in any format. Each event has room for a brief description and an image. Longer descriptions can be written but they won't appear on the timeline, they'll only appear in the printed notes about the timeline. Students can drag and drop events on their timelines to create appropriate spacing between each event.
Applications for Education
The Android and iPad versions of RWT Timeline support multiple user profiles making it a great choice for classrooms that have more students than tablets. The web version of RWT Timeline also supports multiple users.
The aspect of RWT Timeline that I appreciate the most is the flexibility of date formats. In fact, if you look at the following screenshot of my sample timeline you'll see that I didn't use specific dates at all. The use of RWT Timeline doesn't have to be limited to history courses. Students could use RWT Timeline to create timelines of the plot of a story they've read. Or they could use it to plan the plot line of a story they're planning to write.
