Abstract

A computerized teaching system is described including an interactive group communication system, wherein students interact with a teacher and the teacher can obtain quantitative reports on student performance without preprogrammed lessons and where a lesson program can be constructed from the responses of the students. The teaching system may be spread over a large geographic area comprising a multiplicity of learning centers with a multiplicity of students at each center, wherein the students interact with a teacher who is remotely located from one or more learning centers.

Claims

1. An electronic teaching system comprising:

(a) at least two learning centers having a plurality of participant alpha-numeric terminals, each with a common computer and a common communication control unit;

(b) a group leader terminal, located within a teacher'"'"'s center, wherein the group leader terminal includes a keyboard, screen, memory and logic means for displaying multi-character response information from the memory onto the screen;

(c) communication distribution means within the teacher'"'"'s center for communicating with learning centers via a plurality of communication channels;

(d) a transmission buffer within the memory of the common computers in the learning centers for continuously transmitting the multi-character responses, and adapted for storing at least the keystrokes of all the participant terminals in the relevant learning center together with terminal identifying information for the keystrokes for at least the time period between successive communications from the communication distribution means;

(e) means in the communication channels for transmitting the information from each transmission buffer to the memory of the group leader terminal, the information then being displayed on the screen of the group leader terminal, contemporaneously with the multi-character responses being entered at the participant terminals; and

(f) social mode means for coordinating participant terminals within the learning centers to collectively respond to a particular question indicated by the group leader terminal.

2. The system of claim 1, wherein one of the learning centers with a multiplicity of participant terminals is remotely located from the teacher'"'"'s center.

3. The system of claim 1 wherein the two learning centers are each provided with separate lesson storage means and separate comparator means adapted to compare a response from a participant'"'"'s terminal with a programmed correct response in the lesson storage means.

4. The system of claim 3 wherein a reinforcement signal is transmitted to the relevant participant'"'"'s terminal when the comparison is favorable, wherein transmission of the reinforcement signal is independent of transmission rates between a particular learning center and the teacher'"'"'s center.

5. The system of claim 3 wherein the result of comparison is transmitted to the group leaders'"'"'s terminal for display on its screen.

6. The system in claim 1 wherein the group leader terminal further comprises lesson storage means and a comparator for comparing a participant'"'"'s response with a programmed correct response stored in the lesson storage means, the result of the comparison being displayed on the group leader terminal.

7. The system in claim 1 wherein the learning centers are provided with a public display monitor operable from the common computer in the learning center and the group leader terminal is adapted to send characters to the common computers in the learning centers which appear on the public display monitor in each learning center.

8. The system in claim 7 wherein the group leader terminal is further adapted to send a participant'"'"'s response from the memory of the group leader terminal for display on the public display monitors in the learning centers.

9. The system in claim 7 wherein the group leader terminal further comprises means for sending a participant'"'"'s response from the memory of the group leader terminal to the memory of the common computer in the learning center to be displayed on the public display monitors in the learning centers.

10. The system in claim 1, wherein each of the learning centers are each provided with a public display monitor operable from the common computer and the common computer is provided with lesson storage means, the group leader terminal being adapted to send characters to the common computers in the learning centers to cause a message from the lesson storage means to appear on the public display.

11. The system in claim 1, wherein each of the learning centers are provided with audio visual devices operable from the common computer, the group leader terminal being adapted to send characters to the common computers in the learning centers to activate the audio visual devices.

12. The system of claim 1, wherein the group leader terminal further comprises means for selecting an unanticipated multi-character response of a participant terminal and comparing the unanticipated multi-character response with the multi-character responses from other participant terminals.

13. The system of claim 12 wherein the group leader terminal further comprises a score buffer for storing the results of the comparison.

14. The system of claim 12 wherein the number of responses of a similar types are counted and displayed.

15. The system of claim 12 wherein the participant terminals are provided with reinforcement means, for reinforcing a favorable comparison between the selected unanticipated response on the group leader terminal and the responses from other participant terminals.

16. The system of claim 1, wherein a communication channel is provided with a modem at both ends, between each of the learning centers and the group leader terminal.

17. The system in claim 1, wherein the group leader terminal further comprises means for sending a unique identification code to the common computer of each learning center and wherein the learning centers share a common communication channel, the common computers at the learning centers being adapted to respond only to the unique identification code for that computer.

18. An electronic teaching system, comprising:

(a) at least one group leader terminal;

(b) a plurality of participant terminals connected to the group leader terminal, wherein the participant terminals collectively address a frame without a particular programmed correct response;

(c) communication control means for receiving multi-character responses from the participant terminals;

(d) means for storing student responses in a student response storage means;

(e) data processing logic means for simultaneously displaying the participant terminal multi-character responses on the group leader terminal as the participant terminal multi-character responses are received by the communication control means; and

(f) means for selecting from the group leader terminal one of the displayed participant terminal multi-character responses and immediately comparing the participant terminal multi-character response with other responses from the student response storage means, the responses being scored correct where a match occur.

19. The system in claim 18 further comprising reinforcement means for indicating the correctness of one of the participant terminal multi-character responses on all the participant terminals that provide the correct responses.

20. An electronic teaching system, comprising:

(a) at least one group leader terminal;

(b) a plurality of participant terminals connected to the group leader terminal, wherein the participant terminals collectively address a frame without a particular programmed correct response;
