A dictionary style glossary is a useful resource that students can use to look up key terms and find answers to particular questions they may have. A glossary in Moodle can be much more than a word processed document with lots of terms in alphabetical order with explanations for each. Who is responsible for the definitive version of the glossary? Is the glossary in fact, an ever changing and dynamic tool that is being continually updated and refined by other students rather than a static document that some read and others ignore?
A random glossary adds another dimension to this because it sits on the page attracting attention to itself and thus enabling students to absorb information and fuels their need to know more about a particular topic, issue, or question. A course about the Cold War could have a random glossary of quotable quotes from the Cuban Missile Crisis.
