Learning management systems are platforms on the Internet in which teachers and learners can plan, facilitate, and manage a whole course. Researchers mostly in computer and technical sciences, but also some in education, discuss generalities and perspectives about them, implementing and evaluating them, trends and challenges, and case studies. Among the topics are knowledge sharing in a learning management system environment using social awareness, critical factors influencing the acceptance and use of such systems by instructors, enhancing electronic examinations through advanced multiple-choice questionnaires, disability standards and guidelines, and the effective use of electronic learning for improving student skills.
