Design and evaluation of lecture support functions for question databases

Abstract

One of the serious problems in a large-scale class is how to give some level of satisfaction to students. A degree of satisfaction of students will be improved by realizing useful interaction between a teacher and students. Though there are various kinds of communication methods, “questions and answers” databases can be regard as very much important, since the efficiency of questions-answer process is improved and analysis of student behavior can be realized. It is expected to discover important information by analyzing a set of questions. In this paper, we have designed a question-answer database, which will store all questions and corresponding answers. As search functions such as keyword search can be used to analyze data, we have to develop the following two capabilities. (1) Question handling capability (2) Question analysis capability. We have performed experiments by collecting questions, in order to evaluate usefulness of search functions and analysis functions.
