“…CAL systems generally make use of knowledge representations that are carefully constructed to enable the system to leverage aspects of subject content that map onto learning needs and anticipated questions and difficulties. Entailment meshes and task structures are ideal for such applications; indeed, Pask and Scott's work has been widely applied to the development of CAL systems (e.g., Arshad & Kelleher, 1993; Patel, Scott, & Kinshuk, 2001; Thomas & Harri‐Augstein, 2001). However, the development of such support representations is an expert, detailed, and time‐consuming task.…”
