NETWORK-BASED EDUCATION SYSTEM WITH CAPABILITY TO PROVIDE REVIEW MATERIAL ACCORDING TO INDIVIDUAL STUDENTS UNDERSTANDING LEVELS

A network-based education system allowing an instructor to give a lecture to a plurality of students via a computer network, where the instructor can grasp the individual students' understanding levels at his/her discretion and take appropriate supplementary actions to the students in accordance with their respective understanding levels. A questionnaire conducting unit conducts a questionnaire to survey the understanding level of each student concerning a class he/she attends. In response to this, a questionnaire responding unit disposed in each student terminal returns an answer to the questionnaire according to response data entered by the student through a keyboard or other input devices. An understanding level data displaying unit, as part of the instructor terminal, collects the responses to the questionnaire returned from the student terminals and displays the distribution of students' understanding levels on a monitor screen of the instructor terminal. This feature allows the instructor to easily grasp the understanding levels of the individual students. Further, the system provides the students with appropriate review material suitable to their respective understanding levels, thereby allowing better supplementary actions to be taken according to each student's understanding level.
