摘要：This paper describes KADD ET, a cognitive diagnostic environment created to assess the conceptual and procedural learning activities of students. It is composed of a diagnostic engine, DETECTive, and a knowledge acquisition tool developed to fulfil its knowledge representation needs, KADI. Both of them share a Model of Learning Tasks (MLT) as a diagnostic basis. One of the main goals of this environment is to provide teachers with easy-to-use tools that facilitate the construction of learning environments with diagnosis capabilities customized to their particular subject domains and adaptation styles.
