Two carriers of modern educational information

The transmission of modern educational information is inseparable from two carriers: hardware and software. Hardware is the "transmitter" of information, and software is all kinds of films, tapes and disks carrying modern educational information.

Traditional and Modern Teaching Media

There are many ways to spread modern educational information, which can be divided into traditional teaching media and modern teaching media. Traditional teaching media include teaching materials, objects, specimens, models, books, etc. Modern teaching media include visual media, auditory media, audio-visual media and comprehensive (interactive) media.

Unidirectional and bidirectional information flow

According to the reciprocity of information flow, the communication mode of modern educational information can also be divided into one-way and two-way directions. One-way information flow means that the transmission of information is one-way, such as teachers imparting knowledge to students; Two-way information flow means that information transmission is two-way, such as the interaction between students and teachers.
