ACTIVE FEEDBACK SYSTEM IN CLASS USING THE MOBILE TERMINAL

摘要

An active feedback system for stimulating a learner to participate actively in a class by using a mobile terminal is provided to enable a user to transmit questions to a lecture terminal in real time during a lecture or class by using a voice or text message transmission function of a portable terminal. A portable terminal(10) inputs questions from lecture participants in text or voice, and a lecture server(20) receives voice or text data from the portable terminal. The lecture server transmits the voice or text data to a lecture terminal(30) in real time, and the lecture terminal output the transmitted voice or text data. The voice or text message is transmitted to the lecture terminal through the synchronization of the portable terminal in real time.
