As an April Fools joke, Coursera offered an online course on underwater basket weaving as of April 1, 2013. The class was supposed to "consist of short lecture and demonstration videos, between 8 and 10 minutes in length, short quizzes, and practical weaving exercises." However, the joke is seen by some as being disrespectful of indigenous cultures, and the joke designer issued an apology which was posted on the Coursera class page for "Aboriginal Worldviews and Education." The apology read, in part, "By posting the course and video, we were not intending to be disrespectful to indigenous cultures, and we sincerely apologize to anyone we offended by the content of our video."
