A multi-layer arrangement is used to arrange computing servers to be one first-level server and one or more second-level servers each communicable with the first-level server. Each server serves real clients located in a pre-determined site. Furthermore, each server sets up a virtual client to execute the teacher client's activity command so as to locally generate application-specific data, which are then stored in this server. When a communication link to a student client is re-established after an activity interruption, resynchronization of the student client's learning-activity state with the teacher client's is regained based on the locally-generated application-specific data stored in the server that serves the student client without a need to burden other servers."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multi-location learning-activity state management for distance education","description":"A method for delivering distance education for real clients, each either a teacher client or a student client, at multiple teaching sites and a system using the method are provided.
