Algorithms exercise: Find mistakes in Wikipedia articles by René Pickhardt.
From the post:
Today I started an experiment I created an excercise for coursework in algorithms and data structures that is very unusuale and many people have been criticle if this was a good idea. The idea behind the exercise is that studens should read wikipedia articles to topics related to lectures and find mistakes or suggest things that could be improoved. Thereby I hope that people will do something that many people in science don’t do often enough: Read something critically and carefully and question the things that you have learnt. (more discussions after the exercise)
This is great! No only can students practice thinking critically but there is a forum to test their answers: other users of Wikipedia.
Read the article, do the exercises and see how your critical reading skills fare.
