Exploring domain concepts/knowledge is an effective way of learning particularly for task-oriented disciplines. This ex-ploratory learning is often accompanied by cognitive efforts to develop and apply the domain concepts/knowledge, where efforts would enhance learning effects. However, it is not so easy for learners to get good results. The cognitive efforts may cause cognitive overload. Some intelligent/adaptive sup-port is therefore necessary. This article describes a methodol-ogy for supporting exploratory learning that attempts to limit learning space, called exploration space, and adequately con-trol the cognitive load the learners would face in their explo-ration process. We call this methodology "Exploration Space Control" (ESC). In ESC, the extent of the exploration space is controlled according not only to the domain complexity, but also to the learners' competence, understanding levels, experiences, characteristics, and so forth. The control is done by restricting exploration tools provided in user interface, tailoring information to be presented, recommending a few among a number of choices, and so forth. This article also demonstrates an application of ESC to an interactive simula-tion- based system in the domain of the human ear. This sys-tem aims to enhance learning of the structure and functional-ity of the ear and to improve appropriate skills in diagnosing and treating the related diseases. The system also provides several kinds of information resources for exploring the ear and user interface with several exploration tools.
