Filters

Filters are settings that can transform text into more complex forms, such as automatically forming links and embedded multimedia. The main purpose of enabling filters is to make the content more immersive—an attempt to enhance content beyond its written text. In PolyLearn, instructors have the option of turning individual filters off or on.

Setting Filters

Instructors have control of what filters are active. An example of when this would be necessary is when auto-linking of words to the course's glossary terms must be disabled when a student is taking a quiz or test.

  1. In the Settings block, click Course Administration, and then click Filters.
  2. Options for Filters are displayed. Choose to turn each either On or Off via their corresponding pull-down menus.

What does each filter do?


Algebra notation

Algebra notation automatically translates typed equations into a gif image of standard notation for mathematical equations.
Note: The TeX filter must be installed for this filter to function correctly.

Glossary auto-linking

Glossary auto-linking enables words that appear throughout the course website to be automatically linked to their glossary entries.
Note: For this filter to work, the checkbox next to This entry should be automatically linked must be checked when creating/editing each glossary term.

Multimedia plugins

The Multimedia plugins filter finds URLs within the course website that link to multimedia (such as video and audio files) and replaces the text with a player that will display the multimedia content. Below are the supported media formats (as detailed on the Moodle website):

  • .mp3 - MPEG Audio Stream, Layer III
  • .swf - Macromedia Flash Format File (Adobe, Inc.)
  • .mov - QuickTime Video Clip (Apple Computer, Inc.)
