The Make History authoring tool has been built in Adobe Flex. It is currently Windows-only but in due course we hope to make it cross-platform. The authoring tool requires installation of the ‘Adobe Air runtime’ component. Timelines created with Make History can be uploaded to any VLE or website and viewed by students on any platform / web browser that supports the Adobe Flash player.
The current version of the tool is beta 1.05, with beta 1.06 due by the end of March 2011.
