There are also some useful tips on how to use Wikipedia in research as well.
However in a classroom context, I feel that while it can guide a student in understanding an idea or concept, they can easily fall into the trap of relying on it solely for gaining information.
I'd only recommend Wikipedia as a starting point for a research task and generally should not be included in a reference list or bibliography. We need to encourage students to locate resources in different formats from different locations. Students also are taught how to verify their information as they can compare information from one source with another source to ensure that it is correct and accurate.
