Digital network interactive teaching system and teaching interactive method

Abstract

The invention relates to a digital network interactive teaching system, which comprises a computer, an input device and an output device, wherein time-division multiple address and asynchronous serial transmission modes are used between the computer, the input device and the output device, wherein the computer is orderly connected with a network communication card, a network communication switch and a plurality of interactive teaching terminals which are parallelly connected with the network communication switch through an ethernet line. A handwritten interactive teaching method in the digital network interactive teaching system is that a system starts a teaching program, a teacher selects a teaching mode, then a network connecting is built, and the system awaits students to login and enter a teacher end to do the handwritten interactive work with a student end. The system produces and stores interactive work data according to the selected teaching mode, and a teacher replays the interactive work data which is produced by the system to all students and evaluates the work. The network line uses an ethernet network to conveniently wiring in a whole network, the system combines a programmable gate array in field and a single chip microcomputer to control, which leads the steady and the reliability thereof to be higher compared with a multimedia computer network, the power dissipation is low, and the digital network interactive teaching system is economical and environmental.

Description

technical field [0001] The invention relates to a computer network teaching system and a teaching interaction method thereof. Background technique [0002] With the rapid development of science and technology, all kinds of multimedia teaching with the help of computers, networks and other means are gradually being used experimentally. However, due to the limitations of their respective technologies, there are still many technical problems in the interaction between teachers and students that need to be solved urgently. [0003] An all-digital multimedia language laboratory: This teaching system is a digital improvement of the traditional analog language laboratory. Teachers can communicate with students in language and text. Teachers can also communicate with students through external display devices such as monitors and projectors. Teachers' DVDs, display stands and other video content are broadcast to students, but their application is limited to language teaching and cann...
