Course page from a Fall 2013 assignment which allocated students to improve and review Wikipedia articles, including "Food security", "Illegal drug trade" and "Socioeconomic impact of female education". The page sets out the activities the students were required to do during the course, including proposing a change, making change on Wikipedia and reviewing each other's contributions. The course was supported by Wikipedia volunteers and campus Wikipedians. A table at the foot of the page lists the affected articles.
