Learning objects are elements that have been defined as reusable entities. However, their reusability is limited by the heterogeneity of the platforms that support them and by the standards employed in their development. A proposal of ours to deal with learning objects as Web services in order to solve the reusability problem has been presented in previous works. In addition to, the modification of...
Accessibility of e-learning systems to people with some disabilities is a current common problem. So, to create accessible e-learning platforms, we need a richer implementation of their pedagogical content. An ontological representation of learning object can be suitable way to encourage reusability, share and interoperability of learning object. The aim of this study is to present a design of an...
Scientific education is strongly based on laboratory activities, but today laboratories are radically different with respect to their 20th century precursors. Computer technologies, digital networks and on line learning platforms are exploited increasingly in order to publish teaching materials, course calendars, class news and to support on line discussions, assignments and reviews even for face...
Over the Internet, e-Learning has speeded up the knowledge transfer without restrictions on time and space in recent years. In order to achieve the goal of knowledge sharing and reusing interactively, lots of available e-Learning standards have been adapted to complete this purpose. Normally, learning objects meeting these standards are sharable with other e-Learning platforms. Most e-Learning platforms,...
Along with the development of Internet technology, e-Learning as a flexible and convenient educational method has been widely accepted in tertiary education institutions to enhance and facilitate learning. By avoiding costly duplication and enabling the rapid creation of online courses, the employment of Learning Objects (LOs) and their reusability can benefit any educational institution when developing...
In the new learning environments, built width digital technologies, the need to promote quality of education resources, commonly known as Learning Objects, which can support formal and informal distance learning, emerge as one of the biggest challenge that educational institutions will have to face. Due to the fact that is expensive, the reuse and sharing became very important issue. This article...
Current e-learning applications are limited with respect to learning cooperation and communication among learners, because these applications such as on-line courses offered in China often involve large numbers of geographically dispersed students who have diverse learning preferences and different requirements. Constructing learner communities of interest is critical and necessary to implementing...
E-learning is about using IT technologies to support on-line learning processes. In this context, a learning object (LO) is a re-usable digital content, which has some metadata associated with it to facilitate its search, retrieval and processing, which includes assemble it with other LOs to form a more complex one. An interesting form to retrieve and manipulate collections of LOs is declaratively...
This article introduces the concept of e-Learning and gives its corresponding architecture. Based on this three-layer architecture of the e-learning, this article proposes the systematic design and the implementation scheme for teaching the communicational courses while meeting the training requirements of the students of the communication engineering major in the e-learning environment.
The traditional learning style theory is being used in the development of e-learning materials progressively. Usually the process of working with learning styles begins with the development of tests or questionnaires that are focus on determining the preferences of students to learn, and then prepare the material according to them. But once the content is implemented there is no tool to measure or...
The present paper describes an approach for keyword- and concept-based search of relevant learning objects and delivery of them to learners. The paper also proposes to blend the keyword- and concept-based search with personalization to increase relevancy of delivered documents to the learners preferences. The relevancy of learning object to the learner request is defined as a weighted linear combination...
