Description

System and method for transmitting and receiving synchronized contents between Learning Contents Management System and Learning Management Systems}

The present invention relates to a synchronized content transmission / reception system between a learning content management system (LCMS) and a learning management system (LMS), and more specifically, uLMS (ubiquitous LMS) of e-learning / e-learning. Learning contents installed in the learning contents management system (LCMS server # 1) interworking with the learning management system for learning (LMS server # 1) are multicasted by exporting the original contents or by exporting encrypted contents, and synchronized The learning content (A, B, C, D) and content list files are simultaneously distributed to the learning content management system (LCMS server # 2) of another learning management system (LMS server # 2). Learning content management that provides export and import of synchronized content to prevent malfunctions caused by interference of information linked by content numbering It relates to a system for transmitting and receiving synchronized content between a system and a learning management system.

LMS (Learning Management System) is a system that manages students 'grades, progress, and attendance online, and manages students' grades and progress through computer online, as well as managing matters across the school including attendance and absences. System. It is a system that can operate and manage the entire process of teaching and learning from development to delivery, evaluation, and management of learning contents, and is also called a learning management system or a bachelor management management platform.

In addition, LMS applies not only to schools, but also to businesses and public institutions. In the case of a company, the production of educational contents using the Internet is used as a solution interlocking with enterprise resource planning (ERP), knowledge management system (KMS), and human resources management system, thereby invigorating in-house education at a low cost. Public institutions are currently the most utilized system, and are considered to be a system that is effective in fostering human resources required for institutions.

LCMS (Learning Contents Management System) is a system that manages content in an ICT-based learning environment.

In addition, LCMS is a system that develops, stores, and manages content in units of learning objects to provide reusability of previously developed content and adaptive content suitable for learner characteristics. LMS performs the function to support and manage the learner's learning process, whereas LCMS performs the delivery function to deliver the content requested by the LMS and extract the contents accordingly, and the management function necessary to systematically manage the content System.

LCMS is the main management target for learning content, while LMS is a person-centered management system that supports learner learning.

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

The LCMS can be used jointly after the central development by the government and the municipal office of education to develop common elements, but the LMS has a characteristic that it is necessary to individually implement the system according to the purpose of use and the scale of the system development budget.
