PROBLEM TO BE SOLVED: To further enhance each student's comprehension in a lecture by achieving semi-synchronous remote education by combining synchronous remote education and asynchronous remote education.;SOLUTION: A lecture management server 120 refers to each student's lecture data reproducing state, question timing of lecturer's questions stored in a DB and estimated dialog time for the question, and student's questions stored in the DB, and determines individual dialog schedule candidates on the basis of the combination of the presence of the setting of dialog time to be determined according to whether each lecturer's question is asked of each student and, when there is a student's question, the presence of the setting of dialog time for answering the student's question on the basis of predetermined dialog time. Then, an educational effect value is acquired for the entire dialog schedule candidates wherein the individual dialog schedule candidates for each student are combined, and the entire schedule candidate that maximizes the educational effect value is set to be the dialog schedule.;COPYRIGHT: (C)2010,JPO&INPIT
