 What are filters? Moodle has a number of filters which affect how elements of the course are displayed. This video displays in its own player because some multimedia plugins filter has been activated. To see which filters your Moodle administrator has made available, from course navigation click the more link and then filters. Note also that we can view and change filters for individual activities from the more link inside each individual activity as well. We're now on the course filter settings page where we see a list of filters for the course. Activity names auto-linking is useful because it means we can refer to an activity simply by typing its name in a different part of the course and it will link to that activity. The multimedia plugins filter is enabled so we can display our sound and video files in a player. Glossary auto-linking means that if we add a key term to a glossary and then type that key term somewhere on the course it would automatically link to its glossary entry. But here is where it's useful to remember that you can turn this off in individual activities. For example you might not want that in a quiz if the key terms are included in the quiz questions. Let's turn this filter on and see how both the glossary auto-linking filter and the activity names auto-linking filter work in the course. In another video we added a glossary activity. So now with edit mode enabled I'm typing into the summary of the writing section and including a key term from that glossary and I'm also referencing one of the other activities in the course a book called language levels. If we now save the changes we can see that if we hover over the word adjective it takes us to the glossary entry we made in another video and if we click the words language levels it takes us directly to that activity in the course.
