Hypermedia is educational software that presents information and integrates student activities in a virtual learning environment. It allows non-linear presentation of information and learning activities through tutorial packages, knowledge webpages, simulations, and project management. The learner controls the sequence and pace of instruction, making their own decisions on the path and flow of events, similar to a flight simulator that trains pilots. While hypermedia can include different media types, it does not replace real-life experiences or the teacher.
