The document discusses course management systems (CMS), which are internet-based software that manages student enrollment, tracks performance, and distributes course content. CMS have been widely adopted in colleges and universities and are becoming increasingly popular in K-12 classrooms. Common CMS platforms include Moodle, Blackboard, and WebCT. CMS offer advantages like motivating student participation, supporting meaningful learning, and extending instruction outside the classroom through individual and collaborative activities. They also allow for personalized instruction to accommodate different learners and provide enrichment or remediation opportunities.
