Description

System for sending and receiving synchronized content between learning content management system and learning management system {System and method for transmitting and receiving synchronized contents between Learning Contents Management System and Learning Management Systems}

The present invention relates to a system for transmitting and receiving synchronized contents between a learning contents management system (LCMS) and a learning management system (LMS), and more particularly, an uLMS (ubiquitous LMS) of e-learning / e-learning. Learning content on the learning content management system (LCMS server # 1) that is linked to the learning management system (LMS server # 1) for multicasting by exporting the original content, or encrypted content, and synchronized Simultaneously distribute the learning contents (A, B, C, D) and the contents list file to the learning contents management system (LCMS server # 2) of another learning management system (LMS server # 2). Learning content management, providing export and import of synchronized content to prevent malfunction due to interference of information linked by numbering of content The present invention relates to a synchronized content transmission and reception system between a system and a learning management system.

LMS (Learning Management System) is a system that manages students' grades, progress, and attendance online. It manages student's grades, progress, attendance and absence through the computer online. System. It is a system that can operate and manage the entire process of teaching and learning from development, delivery, evaluation, and management of learning contents. It is also called learning management system or academic management operation platform.

LMS also applies to businesses and public institutions as well as schools. In the case of corporations, educational content production using the Internet is used as a solution that interlocks with enterprise resource management (ERP), knowledge management system (KMS), and personnel management system, thereby activating in-house training at low cost. Public institutions are currently the most widely used system, and it is evaluated as a system that is effective for fostering the necessary manpower.

Learning Contents Management System (LCMS) is a system for managing contents in an ICT-based learning environment.

In addition, LCMS is a system that provides adaptive content that is suitable for the reusability of previously developed content and the characteristics of learners by developing, storing, and managing content in units of learning objects. While the LMS supports and manages the learner's learning process, the LCMS delivers the contents requested by the LMS and extracts the contents accordingly, and the system performs the management functions necessary to systematically manage the contents. to be.

LCMS is the main management object, while LMS is a person-centered management system that supports learners' learning.

LCMS supports the automation of content management in a standardized way, and LMS is a website-type system that can be flexibly constructed according to the direction and planning intention of cyber learning.

The LCMS can be used jointly by the government and municipal education offices after deciding common factors and developing them centrally. However, the LMS has the characteristics of implementing the system separately according to the purpose of use and the size of the system development budget.
