Online communication forums allow students to collaborate and construct understandings of course material together, but little is known about students’ discussion participation across online and blended (hybrid) classroom environments. This study begins to address this research gap by examining students’ asynchronous discussions (number and length of “initial” and “subsequent” discussion posts)...

In this contribution, we explore the use of e-voting based cryptographic protocols to implement synchronous as well as asynchronous online electronic evaluation procedures in order to alleviate the problems arising from the lack of interpersonal transaction in open and distance learning environments. Our approach is based on the similarity of privacy requirements exhibited on such environments ...

This paper presents a Performance Oriented Adaptation Agent (POAA) architecture that improves adaptive selection of Learning Objects stored in distributed knowledge repositories. This approach can enhance adaptation process in the Open corpus Adaptive Educational Hypermedia System (OAEHS) Server. The focus is on enhancing existing adaptive selection process by considering network performance fa...

As the world gets connected, people need to access information anywhere, anytime, whatever the device is (laptop, cellular phone...). They look for situated services that identify and package relevant context sensitive information. Situated services for mobile people must integrate 1) user profile: who the user is; 2) space: where the user is; 3) time: when the user needs the service 4) context...

With the rapid advance of stand-alone e-learning systems, we believe a sharable and interoperable portal platform capable of integrating various existing learning systems is critical for the future development of elearning systems. We highlight two problems as the root causes for current ineffective sharing of learning resources: learning object interoperability and learning activity interopera...

Web-based learning environments are extensively used nowadays. These environments maintain and produce vast amounts of data. Such vastness lead to the application of data mining techniques so as to further improve usability and qualify e-learning platform courses content. This paper proposes a platform dependant framework for recording, processing and analyzing data from Learning Management Sys...

In the current paper we firstly give a short introduction on e-learning platforms and review the case of the e-class open e-learning platform being used by the Greek tertiary education sector. Our analysis includes strategic selection issues and outcomes in general and operational and adoption issues in the case of the Technological Educational Institute (TEI) of Larissa, Greece. The methodolog...

E-government has emerged as one of the most promising means to reform the public sector. E-government is now being used to improve services for assisted living. The purpose of assisted living services is to provide ways for elderly people to continue to live at home. However, these services require formal decisions by local government officials. Therefore Swedish municipalities aim to move cont...

This article presents an economic model of a monopoly retailer with supply and demand uncertainties that enables the study of incentives for B2B e-procurement technology investments that permit inventory coordination and operating cost control. In this context, we focus on the information technology (IT) adoption behavior of firms, emphasizing the trade-offs they make between managing supply pr...
