Abstract: PURPOSE: A lecture progress state notification method is provided to store data on a lecture progress state and to check the lecture progress state if a user requests a lecture so that it can restart the lecture from the stopped state after a system recovery though a system fails during a lecture. CONSTITUTION: The method comprises steps of starting a lecture(1000), storing a lecture start time and data on a lecture receiver(1010), outputting lecture contents according to a lecture progress(1015), storing a start/finish ID for each lecture chapter of the lecture contents to be output to the lecture receiver(1020), linking to reference information if the lecture receiver wants linked reference information(1021, 1030), offering questions for checking an understandability on the offered lecture and storing a start/finish ID for each question paragraph if the lecture is completed(1022, 1040), offering a hint, a correct answer or a question solution step according to a request(1041, 1050, 1042, 1060), storing a lecture completion ID if all the question solution steps are offered(1061, 1062), completing the lecture according to a request of the lecture receiver(1070, 1071), and storing a lecture completion time at a database(1080).
