For the benefit of those who would like to more about how the probability module was created and is delivered, it was initially developed over a period of roughly three weeks in January 2012 by members of the Department of Mathematics at the University of British Columbia. Technologies that the module uses are supported by the Centre for Teaching and Learning Technology.

Delivery Systems

The content management system WordPress was used to present material in the module. A set of WordPress plugins were added to extend the functionality of the site:

  • Simple CSS: to allow customizability of aesthetic elements (lists, tables, fonts, etc)
  • FlexiPages: to offer the "Site Map" on the right sidebar
  • NextPage: to include the "previous" and "next" buttons on most pages

The content of the probability module lives on the UBC Wiki (which is an installation of a MediaWiki) on the Faculty of Science "namespace". The wiki supports

  • a revision history
  • watch lists
  • talk pages
  • a book creator that can collect the module content into a single or multiple PDF

All equations are rendered as images in the UBC Wiki. This approach has these advantages:

  • every image has an automatically generated alt tag in LaTeX, that allows users, who often have a disability, to be able use a screen reader to access equation content,
  • pages on the website can be reliably converted to PDF format for printing, and
  • all modern browsers can view these images
