1. A rapidly responsive, real-time interactive, computer-based education system comprising:

  • central computer means for storing and executing interactive educational software and providing a forward channel data flow, said forward channel data flow including digital code sequences indicative of data to be displayed by a receiving display terminal, the forward channel data flow rate of said digital code sequences per receiving display terminal averaging hundreds of bits per second;

    a plurality of remotely located, keyboard actuated display terminals, each said display terminal receiving certain code sequences from such forward channel data flow, displaying data represented thereby and providing as an output, real-time user responses to said displayed forward channel data in the form of keystroke data, the flow rate of said keystroke data averaging tens of bits per second;

    high speed communications means dedicated to unidirectionally transmitting said forward channel data flow to said display terminals, said communications means including uplink-satellite transmitting means and at least one downlink satellite recevie-only means; and

    land-based communication means including a reverse channel for transmitting said keystroke data from each said display terminal to said central computer means whereby said computer means responds to said key stroke data in its execution of said interactive educational software.
