Seeing the world's knowledge as a public asset that can be accessed, shared, used and reused, etc. mediated by technology, especially ICT, is a potent idea and it may have an influential impact on educational processes within our society. A decade of development of initiatives that offer open courseware and open educational resources has passed, and all the related projects have contributed to the provision of open university-level digital educational materials. For the time being, there is no articulated set of quality criteria to be used for development, use, modification, evaluation, and comparison of such resources, though, there is concern about this subject. We introduce here a set of criteria for Quality Assurance of open courseware and open educational resources, from a social and constructivist perspective, as a first step towards construction of a quality model. They have been grouped in four categories related with content, instructional design, technology and courseware evaluation. © 2014 Springer-Verlag. Source

Despite the momentum of the open courseware movement around the world, no quality criteria and metrics for evaluation of open courseware or open educational resources' repositories are available yet. Therefore, learners and instructors have no support and guidance in their quest for locating the most suitable learning resource that fulfills their educational aims. The same is true for developers, who have no guidelines for designing and building such educational resources. We present here an evaluation and comparison between two open courseware on data structures and algorithms, which are available from two important open courseware providers and that comply with different open courseware paradigms. Both evaluation and comparison rely on our socio-constructivist quality model, which consists of a set of quality criteria that serve as general guidelines for development, use, modification, evaluation, and comparison of open educational resources and open courseware. © 2014 Springer-Verlag.

In this paper, we analyze and discuss some of the challenges regarding safety, security, and privacy involved in developing a vehicle tracking system, zooming on the tracking device. Potential concerns as vehicle and tracking system safety, tampering activity, criminal activity, and unauthorized access to the system are approached and several solutions are presented. © 2013 IEEE.

Lately there has been a significant boost of interest in music digital libraries, which constitute an attractive area of research and development due to their inherent interesting issues and challenging technical problems, solutions to which will be highly appreciated by enthusiastic end-users. We present here a DL that we have developed to support users in their quest for classical music pieces within a particular collection of 18,000+ audio recordings. To cope with the early DL model limitations, we have used a refined socio-semantic and contextual model that allows rich bibliographic content description, along with semantic annotations, reviewing, rating, knowledge sharing etc. The multi-layered service model allows incorporation of local and distributed information, construction of rich hypermedia documents, expressing the complex relationships between various objects and multi-dimensional spaces, agents, actors, services, communities, scenarios etc., and facilitates collaborative activities to offer to individual users the needed collections and services.

Group creativity is a hot topic in the creativity literature, yet no method to obtain the most creative teams given a group of individuals is available. We introduce here a method for building creative teams, based on unsupervised learning and implemented with support from a multiagent system. Our first experiments with using this method for grouping learners involved in online brainstorming are presented as well. © Springer International Publishing Switzerland 2014 Source
