| Description | Problem solving is an important component of education. To make problem solving activities attractive, it is important to confront students with problems of suitable difficulty -- neither too easy, nor too difficult. Since students vary in their skills, it is also crucial to make problem recommendations individually adaptive. We present a novel problem response theory, which predicts how much time will a student need to solve a given problem. Our theory is an analogy of the item response theory, but instead of probability of a correct answer we model problem solving time. We introduce a problem solving tutor, which uses the theory to make adaptive predictions and to recommend students problems of suitable difficulty. |
