Service-Oriented E-Learning System

Abstract

Instead of building an e-Learning system from scratch, it can be assembled by choosing the required functionalities from a set of web services related to e-Learning. Web services eliminate many interoperability issues between components written and running on different hardware and software platforms. This study aims to construct a set of e-Learning web services. With these web services, new e-Learning system(s) can be constructed by choosing the services which are required. The developed web services include Assessment, Course Management, Grading, Marking, Metadata, Registration and Reporting web services. These web services are highly in demand as the functionalities for each of the web services are very useful and important in e-Learning systems. In Marking web service, rubrics can be defined to assist in assessment evaluation. In Metadata web service, Learning Object Metadata (LOM) is applied to capture the description of the learning objects.

A Grid-Enabled Infrastructure for Resource Sharing, E-Learning, Searching and Distributed Repository Among Universities

“…It introduces a collaborative computing platform framework that supports the creation of multi-user collaborative sessions, allowing users to self-organise and communicate, share tasks, workloads, and content, and interact across multiple different computing platforms. The work in [23] proposes a service oriented e-learning systems that include assessment, course management, grading, registration and reporting web services. eframework in [24] is a service-oriented approach for education and research, the methodologies used helps to identify shared and common services that form a part of the information environment.…”

A Trust Evaluation Model for E‐Learning Systems

“…The system was made with Adobe Flash, and it was capable of recognizing two positions and motions of user's fingers from a Universal Serial Bus camera (Nagata et al, 2009). As the Web services eliminate many interoperability issues for distributed components running on different hardware and software platforms, a new e-learning system based on Web services has been proposed, in which the developed Web services include Assessment, Course Management, Grading, Marking, Metadata, Registration, and Reporting Web services (Su et al, 2007). As a powerful and expressive non-textual medium that can capture and present information, instructional videos are extensively used in e-learning service systems.…”

Putting adaptive granularity and rich context into learning objects

“…[3] And some others [8] tried to include the information created in the use of the learning object in the metadata to achieve the "value adding" target, such as keeping the natural language information as one part of the context description. Some works have been done to give the extension of the metadata of the content object, according to the needs of the services, such as to extent the LOM to include "the marks and grade awarded to a particular learning object" into the metadata [9]. However, these researches don't give us a common framework to deal with this question.…”
