摘要: A system for providing network-based interactive learning including at least one network-connected passive server and at least one network-connected active server, each executing software from a non-transitory physical medium. The passive server provides a log-in function providing log-in for a student for a specific learning session, a provisioning function downloading reference materials for the particular learning session to the student's appliance after log-in, and a switch function connecting the student's appliance to the at least one active server after the reference material is downloaded. The active server provides control of the specific learning session by managing communication between a presenter and individual logged-in students, and by transmitting control messages to the student's appliances, the control messages initiated by activity of the presenter, and by causing display of individual portions of the reference materials downloaded to the student's appliances by the at least one passive server after log-in.
