By using information technology, it has become possible to get large amount of learning histories. However, it is still difficult to use them effectively. We propose a technique for abstracting each learner's learning history and visualizing the result as a process of learning activities representing the feature of learner's behavior. This technique makes it possible to show the feature of learning activity, not by getting into the contents of learning.
