The document discusses learning management systems (LMS), which allow flexible and distance learning. LMS is software that supports both distance and face-to-face education. It discusses how human-computer interaction plays an important role in developing LMS and how learner performance is shaped by knowledge, skills, and learning attitudes. Cognitive theory relates to how students prefer to learn when using LMS, with novices preferring a single layout due to anxiety and experts preferring multiple layouts. LMS developers must consider how the system will be used when designing courses.
