Model Design of Reusable Learning Objects Constructed in LCMS (1)

[Abstract] At present, a large number of online learning resources are difficult to share, and different education systems are difficult to communicate with each other. At the same time, learning resource developers and developers are difficult to create personalized learning resources in such a context. Design and development staff put forward higher requirements. It also hinders the sharing and exchange of online education resources. Regarding the issue above. This paper is based on the research of a new generation of network education application system-learning content management system. Combined with existing network education technology standards. Go deep into the grassroots to discuss the construction model of reusable learning objects in the learning content management system and the internal element construction principles. Provide a set of construction strategies for instructional designers and content developers. Finally, this paper also gives the basic method of constructing learning objects.

I. Introduction

Modern online education offers people a whole new way of learning. It has its unique features: it can enable the sharing of educational resources; create a personalized learning space for learners: promote the development of educational socialization and provide a lifelong learning concept for human beings. therefore. Many countries have invested heavily in this area. The impact on the international market after joining the WTO. China must speed up the development of online education. Efforts are made to promote the cultural quality of the people throughout the country. and. At present, China's online education is facing a lot of problems that need to be solved, such as the construction of online education resources. It manifests itself as: various types of educational resources are complex, construction standards are different, and the level of resource sharing is low. Especially when creating reusable learning content, instructional designers and content creation personnel are incapable. Against the above problems in the field of online education. This article is based on the study of a new generation of online education application system—Learning contents management system. Combined with existing network education technology standards. In-depth exploration of the reusable learning object (Reusable learning 0bject) in the LCMS construction model and its internal element construction principles. Provide a set of construction strategies for instructional designers and content creators.

Second, learning content management system

(LCMS) Architecture and Composition Reviewing the development of LCMS, it has gone through four stages: general resource library, learning management system, external supply network education platform, and learning content management system. In general, LCMS is a system that can create, store, publish, and manage personalized learning content in the form of learning objects.

1. LCMS system architecture and system composition

According to the definition of LCMS. It combines the core features of LMS and CMS. Based on the RLO and related network education technology standards, the LCMS system architecture can be represented as shown in Figure 1.

In the figure, the producer uses the existing learning content, the content of various existing file formats, and new content to create learning objects, which are then combined into a library of learning objects. We must fully consider the different needs of learners when publishing learning objects. One LMS is nested in the LCMS. The LMS is controlled by the network administrator on the one hand, and connects the user interface used by the active web page publishing device and the learner on the other hand, and is also connected with other systems. Expanded LCMS functionality. LCMS is mainly to provide users with a network education application system that can create learning content, store learning objects, manage learning, and dynamically publish personalized learning content. It has the following four components: learning object library, production tools, dynamic publishing interface, and management software. The Learning Object Library is at a core location, and it plays a pivotal role in the operation of all aspects of LCMS.

2. The Reusable le-arning objects repository (RLOR) in the LCMS is a database that can store and manage learning content. It is mainly used to mark and store RLO. This facilitates effective management of various RLOs. It combines learning object metadata description model, RLO's internal structure framework and object-oriented database technology ideas to establish, and has made great contributions to the construction, storage, management, sharing, and reuse of individual RLOs.

According to the previous LCMS system architecture diagram, we can go deep into the RLOR to explore. When the system invokes learning objects in the RLOR, factors such as the conceptual content of the learning content, the state of the learner, the learning process, and the personality of the learner are taken into consideration. This kind of adaptive learning research needs to be further developed. From this we can see that the internal operation of RLOR is very complicated, and it will only show a virtuous cycle state in LCMS.
