In working with other CMS, I have used a facility that allows me to manage the translation of a page from one language to another.
To elaborate, in Canada, I am required to present a course in both English and French. With the Drupal CMS, I have the capability to turn on an editing feature that allows me to take a page and manage the process of translating it from English to French (or visa versa). In addition, the "shadow" translated page is displayed when the appropriate language is selected.
Is there a similar add-on in Moodle?
