What is a wiki? According to the most well-known wiki, Wikipedia, "A wiki is a web application which allows people to add, modify, or delete content in collaboration with others. " (Here, wikipedia is quoting the Encyclopedia Britannica). Some teaching staff at Universities have begun to integrate this editing and reviewing tool into their teaching. The VLE, Blackboard has a component called Campus Pack that allows staff to give students assignments that are based around contributing to a wiki. Here, Psychology Lecturer, Gareth Hall of Aberystwyth University discusses his experience of getting students to engage with reviewing work and creating an online glossary using a wiki.
