With the progress of the information and communication technology, classes using computers are being conducted in many schools these days. In addition, GUI programming environments such as Squeak eToys start to be accepted as a tool used in classes. In such classes, instructors have to achieve various tasks including proceeding with classes and supporting learners, which leads to the difficulty to grasp the learning progress of learners. In this paper, we will propose a method to extract characteristic images from periodically captured screen images of GUI programming environment, which are significant to grasp the learning situation. We also develop a system to provide instructors with these extracted images. As a result of applying this system to a real workshop utilizing a GUI programming environment, it has been shown that the characteristic image extraction can be achieved in practical time, and according to the subjective evaluation it is possible for instructors to mostly grasp the learning process.
