Classmix.net is an online classroom management tool for both rapid attendance taking (when students log in with their Internet devices such as smartphone) as well as seating arrangement tools for random pairing. The pairing tool helps to establish a fair and productive classroom environment. This is accomplished by removing both the instructor and students from the selection process. This system also keeps a history so no two students will be paired twice during a particular class session until it runs out of possible or probable combinations -- or is reset.
