Investigating Q&A System Requirements for Effective Instructor-Learner Interaction in e-Learning Service Environment

Instructor-learner interaction is one of the mostimportant elements in e-learning service environment, but lots of learning management system uses general bulletin board system as Q&A system, thus have many limitations supporting interactions between instructor and learner. In this paper, we identify the problem by analyzing the usage of Q&A system in Korea Digital University, and propose a wiki-based Q&A system requirements and features for effective interaction between instructor and learner. With the proposed system, we expect that instructor and leaner continuously take part in question and answering activities, leading effective interaction in e-learning service environment.
