Abstract:	Providing methods and systems for a computer-aided group-learning environment, where a number of users can interact and work on a subject together. The system and method can monitor and analyze users' inputs. The analysis process can identify a user's performance on the subject, and can understand some of the user's traits, such as confidence level and learning attitude. The system can include an interaction controller, which sets a duration of time for the users to communicate in a dialogue environment. Working on the subject in a group and working alone can be intertwined. For example, the users first work on the materials generated individually, and then solve the problem together in a dialogue environment. During the dialogue session, the interaction controller can provide hints to the users. The system can also include a user registry, which restricts the users who can use the embodiment to work on the subject. The registry can receive potential user's characteristics to determine whether such user may be allowed to join the existing users to work on the subject. The registry can also access a summarized profile of the existing users to help the potential user make joining decisions. The system can also include a notepad for a user to take notes. The interaction controller can also guide the user to take notes.
Claim:	We claim: .[.1. A computer-aided group-learning method for more than one user to work on a subject, the method comprising the steps of: setting a duration of time for users to communicate in adialogue session so as to allow the user to work on materials on the subject; and monitoring at least one user's inputs during the dialogue session so as to have the monitored inputs available for analysis to guide at least one user back to the subjectin the dialogue session when one or more users have been distracted from the subject; such that the dialogue session provides an interactive environment to help the users learn..]. .[.2. A computer-aided group-learning method as recited in claim 1 wherein the materials for at least one user to work on are tailored to that user based on monitored inputs..]. .[.3. A computer-aided group-learning method as recited in claim 1 further comprising the step of responding to a user's natural-language question..]. .[.4. A computer-aided group-learning method as recited in claim 1 further comprising the step of restricting one user from communication with at least one other user..]. .[.5. A computer-aided group-learning method as recited in claim 1 wherein the analysis includes analyzing the relevancy of the user's inputs..]. .[.6. A computer-aided group-leading method as recited in claim 1 wherein the analysis is also for generating a profile of one or more users..]. .[.7. A computer-aided group-learning method as recited in claim 1 further comprising the step of restricting one or more users who can work on the subject..]. .[.8. A computer-aided group-learning method as recited in claim 7 wherein the restriction is on limiting a user to observing but not interacting in the dialogue session..]. .[.9. A computer-aided group-learning method as recited in claim 1 further comprising the step of restricting a potential user from learning the subject with the more than one users based on information related to the potential user..]. .[.10. A computer-aided group-learning method as recited in claim 1 further comprising the step of retrieving information related to one or more users for a potential user to decide on learning the subject with one or more users..]. .[.11. A computer-aided group-learning method as recited in claim 1 further comprising the step of guiding the user to take notes on the subject so as to help the user learn the subject; wherein the guidance is related to the subject..]. .[.12. A computer-aided group-learning method as recited in claim 1 wherein: the users communicate in a mode of communication; and the mode of communiaoin can be selected from a unicast, multicast and broadcast mode..]. .[.13. A computer-aided group-learning system for more than one user to work on a subject, the system comprising: a controller configured to set a duration of time for users to communicate in a dialogue session so as to allow the users to workon materials on the subject; and a monitoring apparatus configured to monitor at least one user's inputs to the system during the dialogue session so as to have the monitored inputs available for analysis to guide at least one user back to the subjectin the dialogue session when one or more users have been distracted from the subject; such that the dialogue session provides an interactive environment to help the users learn..]. .[.14. A computer-aided group-learning system for more than one user to work on a subject the system comprising: a plurality of notepads, with at least two of said notepads coupled together to allow information to communicate between eachother; at least one of the notepads being configured for a user to take notes while working on the subject through the system; and a notepad controller configured to monitor the user's inputs to guide the user to take notes on the subject so as to helpthe user learn that subject; wherein the guidance is related to the subject, and the system allows more than one user to work on the subject in a dialogue session to help the users learn..]. .[.15. A computer-aided learning system as recited in claim 14 wherein the guidance is presented in the notepad..]. .[.16. A computer-aided learning system as recited in claim 14 wherein the guidance depends on the user's strength in the subject..]. .[.17. A computer-aided learning system as recited in claim 14 wherein the system is configured to allow the user to cut materials on the subject the user has received, and paste the materials in the notepad..]. .[.18. A computer-aided learning system as recited in claim 14 wherein the system is configured to allow the user to link the notes taken to the subject's materials that the user is working on..]. .[.19. A computer-aided group-learning system as recited in claim 18 wherein the link is from an area in the notes to a point in the materials..]. .[.20. A computer-aided group-learning method for more than one user to work on a subject, the method comprising the steps of: providing a plurality of notepads, with at least two of said notepads coupled together to allow information tocommunicate between each other; allocating an area in a notepad for a user to take notes while working on the subject; and monitoring the user's inputs to guide the user to take notes on the subject so as to help the user learn the subject; whereinthe guidance is related to the subject, and the method allows more than one user to work on the subject in a dialogue session to help the users learn..]. .Iadd.21. A computer-implemented group-learning method for more than one user to work on a subject, the method comprising: setting a time for a group of users to start a dialogue session to work on materials related to the subject so as toprovide an interactive environment to help the users learn; allowing a user to share materials generated by the user with other users, with the user's changes in the materials available to be seen by the other users in real time during the session; retrieving materials related to the subject during the dialog session for the group of users; assessing, during the session, the understanding of at least one user in an area of the subject; allowing some of the users to interact among themselvesprivately, separate from at least one other user, and among the some of the users, allowing one user to transmit materials to the other users, with the materials available to be received by the other users during the session; and generating a reportthat includes information regarding the understanding of the at least one user in at least the area of the subject, wherein the report also can include information regarding the understanding of a number of users as a group in at least one area of thesubject..Iaddend. .Iadd.22.
