A system for increasing user interaction with a digital video library. In response to receiving a question by an interactive digital video library server from a user regarding course material being presented from a digital video library, it is determined whether the question is in an audio format. In response to determining that the question is in an audio format, the question is converted into a text format. The course material is searched in a time sliced video index database for an answer to the question using keywords found in the text format of the question. Also, other course materials similar to the course material are searched in a video knowledge base. A weight is assigned to each search result hit found in the course material and the other course materials. Search result hits are outputted in a priority order according to assigned weight and user preference.

The present invention is a system and method for maintaining the integrity of data during the offline mode of an e-learning process. The invention maintains the integrity of online course material in a learning management system by determining when a student attempts to access online course material and to downloaded the material from a learning management server to a student server for offline utilization resulting in an offline access mode. The invention then provides a set of procedures for monitoring the course material when it has been accessed. The set of procedures may determine that the course material is in an offline access mode and prevent the student from accessing the course object from the learning management server while the course object is in the offline access mode. Further, the system and method of the present invention may also serve to synchronize the course material between the learning management server and the student server by copying the course material from one server to another. In one embodiment, the system and method of the present invention can prevent a student from uploading the course material to the learning management server unless the student has completed the one or more progress objectives associated with the course object. Finally, the set of procedures can provide a security mechanism to insure the security of the online course material when it is in the offline access mode.

An on-line course system involves an On-Line Course Content Serving Web Server (OCCSWS). The OCCSWS serves, or otherwise enables the providing of, on-line course materials such as textual materials and/or a video to a large number of remotely located students. The students view the course materials and take part in the classes remotely via the internet. The OCCSWS performs volunteered user data collection, thereby obtaining for each student items of first classification information. The OCCSWS performs behavioral user data collection, thereby obtaining for each student items of second classification information. The items of first and second classification information are used to group the students into groups. The OCCSWS then communicates, to each student, an indication of the group to which the student has been assigned. The OCCSWS facilitates the students engaging in group activities, monitors the students, and if necessary prompts the students to perform certain group activity tasks.

Techniques pertaining to automating generation of curricula for a class of students with blended-learning contents are presented. The blended-leaning contents provide common topics shared by all the students in a class as well as self-learning materials for sub-groups of the class. This approach creates curricula optimally attending to students with different interests and backgrounds. The course materials are selected by searching multiple external sources publically available while filtering the search results through inputs of the students and requirements set by the instructors. The course contents and schedules of the curricula are further optimized by organizing the filtered search results with respect to a set of constraints.
