A New Instruction System by Network

This paper suggests a new type of instruction system. A method of communication among several nodes in the network is presented which uses low level network protocol and solves the problem of transmitting image from one node to many nodes by network on real time. In this environment, teacher's machine, student's and a server are connected by high speed ether net. Under the control of the system, the teacher can lock student's keyboard, transmit text or image screen among students, build a electronic cursor on student's screen and move it, assign exercises or gather student's answers. The student also can put question to the teacher, talk with other students by electronic phone, etc. The system is to use network and multimedia technique to build a distributed instruction environment. The paper also develops a new concept of a CAI method which changes traditional passively learning to an actively learning method.
