History

All editable pages on WikiEducator have an associated page history, which lists all changes made to the page in reverse-chronological order. You can access this information by clicking on the history tab that is located at the top of every page. Viewing the Revision history of a page is similar to looking at the Recent changes page, but in this case the changes are just for this page.


Difference between revisions

The Revision history page displays a list of all edits made to the wiki page. The radio buttons designate which versions of changes will be compared when you hit the Compare selected versions button.

In addition to displaying the list of all edits made to the wiki page, the Revision history page also allows you to compare changes between one edit of the page and others. A diff is the difference between two versions. For every version or change that has been made to the page there are potentially two radio buttons: the left column is for selecting the older version, the right column for selecting the newer one. Pressing the Compare selected versions button displays the difference between the two versions.





Activity

Take a look at the history of this page by clicking on the history tab above. Select the versions you want to compare by clicking the radio button beside each and click on the Compare selected versions button at the top or bottom of the list.

If you're not sure what to do - take a look at the Show me how screen movie. This is an animated screen capture. (If you have dialup connection, you may want to skip this.)




If you have completed the above Activity you would have noticed a screen that looked similar to this:

The "diff" page displays after hitting the Compare selected versions button.

The right hand side displays the most current version of the page, while the left shows the previous state. From this diff we can see that the user (Mackiwg) changed Line 50 from "46 Weeks" to "50 Weeks" and also added a note about how the project duration was estimated.

Viewing the diff between two versions of a page is the best way to get a detailed view of what exactly has been changed on a page.
