Abstract: This online motivation system is not a learning method. It enables an educator to deliver an identical virtual reward, called a bonus, to every member of a learning team. The learning team consists of learners and their tutors assembled by the educator for online game play in the reward environment. The educator tasks the learner with goals in the learning environment and tasks the tutor with helping the learner to succeed. When the learner demonstrates satisfactory progress in the learning environment, every learning team member receives the virtual bonus in the reward environment. When the educator notifies the system of unsatisfactory progress by the learner, the system communicates penalty imposition while removing the virtual bonus from every learning team member. The system automatically restores the virtual bonus to the learning team. In this way, the educator rewards learners for doing assigned work and rewards the tutors for helping the learners.
