Abstract

A computerized teaching system is described, which comprises an interactive group communication system, wherein students in a first group interact with a teacher in Social Mode, and, in some case, while students in a second group proceed with work in Independent Mode.

Claims

1. An electronic teaching system, comprising:

(a) at least one group leader terminal;

(b) a plurality of participant terminals connected to the group leader terminal;

(c) subject matter storage means for storing a plurality of subjects, wherein each subject includes at least one frame;

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

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

(f) group designation means for dividing the participant terminals into a plurality of groups, wherein the participant terminals within a group are isolated from the participant terminals in other groups;

(g) Social Mode means, operative within a first group, for coordinating the participant terminals within the first group to collectively address a frame from the subject matter storage means, wherein the Social Mode means comprises means for addressing an empty frame and means for comparing a response entered on a participant terminal with a desired response after a response action is completed; and

(h) Independent Mode means, operative within a second group, for allowing the participant terminals within the second groups to independently address a frame from the subject matter storage means.

2. The system of claim 1, further comprising means for comparing at every keystroke a response entered on a participant terminal with an answer in a frame stored in the subject matter storage means and means for supplying an ongoing correctness indication for the response entered on the participant terminal while the response is being entered, wherein the correctness indication is simultaneously displayed on the group leader terminal.

3. The system of claim 1, wherein the Social Mode means further comprises audio-visual means, under the control of the group leader terminal, for displaying audio-visual material pertaining to the frame to the first group.

4. The system of claim 1, wherein the Social Mode means further comprises means for simultaneously displaying selected responses of the first group on a public display.

5. The system of claim 4, wherein the Independent Mode means further comprises means for preventing response times from being significantly affected when the first group is using a public display.

6. The system of claim 1 wherein the Social Mode means further comprises means for storing student responses in student response storage means, wherein one of the responses from the student response storage means is selected and stored in the subject matter storage means.

7. An electronic teaching system, comprising:

(a) at least one group leader terminal;

(b) a plurality of participant terminals connected to the group leader terminal;

(c) subject matter storage means for storing a subject, wherein the subject comprises a plurality of frames;

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

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

(f) Social Mode means for coordinating the participant terminals to collectively address a frame from the subject matter storage means, wherein the Social Mode means comprises means for addressing an empty frame and means for comparing a response entered on a participant terminal with a desired response after a response action is completed; and

(g) means for simultaneously displaying a part of the frame on all the participant terminals by selecting the frame at the group leader terminal.

8. The system of claim 7, wherein the Social Mode means further comprises means for displaying a plurality of responses on the group leader terminal and means for independently displaying only a particular response on a public display.

9. The system of claim 7, wherein the participant terminals further comprise means for adapting the participant terminals for use by handicapped students, wherein the frame are programmed with at least two correct answers so that a handicapped participant can response with a single character response that is compared against a first correct answer based on a multiple choice question requiring a single character response, while simultaneously a non-handicapped participant can respond with a multi-character response that is compared against a second correct answer.

10. The system of claim 9, wherein the participant terminals further comprise means for displaying variable size characters.

11. An electronic teaching system, comprising:

(a) at least one group leader terminal;

(b) a plurality of participant terminals connected to the group leader terminal, the plurality of participant terminals comprises at least one participant terminal located remotely from the group leader terminal;

(c) communication control means for transmitting data between the group leader terminal and the at least one remotely located participant terminal, wherein the communication means receives multi-character responses from the participant terminals;

(d) subject matter storage means for storing a subject, wherein the subject comprises a plurality of frames;

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

(f) Social Mode means for coordinating the participant terminals to collectively address a frame from the subject matter storage means, wherein the Social Mode means comprises means for addressing an empty frame and means for comparing a response entered on a participant terminal with a desired response after a response action is completed;

(g) audio-visual means, attached to the at least one remotely located participant terminal, for displaying the frames from the subject matter storage, wherein the frames contain audio-visual control codes to activate the audio-visual means; and

(h) public display means, attached to the group leader terminal, for displaying messages, wherein messages displayed on the public display means are transmitted to the at least one remotely located participant terminals.

12. An electronic teaching system, comprising:

(a) at least one group leader terminal;

(b) a plurality of participant terminals connected to the group leader terminal, the plurality of participant terminals including at least one participant terminal located remotely from the group leader terminal;

(c) subject matter storage means for storing at least one subject, wherein each subject includes at least one frame;

(d) two-way data and voice mode communication means, adapted to be controlled from the group leader terminal, for transmitting data and voice conversation between the group leader terminal and the at least one remotely located participant terminal;

(e) means for simultaneously addressing all the participant terminals, including the at least one remotely located participant terminal, to a desired frame in the subject matter storage means by selecting the desired frame at the group leader terminal;

(f) communication control means for receiving multi-character responses from the participant terminals, wherein the communication means comprises tone generation means, actuated from the group leader terminal, for switching from voice to data communication and from data to voice communication at the at least one remotely located participant terminal; and

(e) data processing logic means for simultaneously displaying the participant terminal responses on the group leader terminal as the responses are received by the communication control means.
