1. Proceedings of the International Association for Development of the Information Society (IADIS) International Conference on Cognition and Exploratory Learning in Digital Age (CELDA) (Madrid, Spain, October 19-21, 2012)

Abstract

The IADIS CELDA 2012 Conference intention was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There had been advances in both cognitive psychology and computing that have affected the educational arena. The convergence of these two disciplines is increasing at a fast pace and affecting academia and professional practice in many ways. Paradigms such as just-in-time learning, constructivism, student-centered learning and collaborative approaches have emerged and are being supported by technological advancements such as simulations, virtual reality and multi-agents systems. These developments have created both opportunities and areas of serious concerns. This conference aimed to cover both technological as well as pedagogical issues related to these developments. The IADIS CELDA 2012 Conference received 98 submissions from more than 24 countries. Out of the papers submitted, 29 were accepted as full papers. In addition to the presentation of full papers, short papers and reflection papers, the conference also includes a keynote presentation from internationally distinguished researchers. Individual papers contain figures, tables, and references.

2. The 21st Century Information Environment.

Author

Badger, Rod

Abstract

This paper on the 21st century information environment begins with a section that discusses the impact of e-commerce over the next ten years. The second section addresses government focus areas, including ensuring a telecommunications infrastructure, developing the IT (information technology) industry, promoting innovation and entrepreneurship, establishing a regulatory regime that will provide a secure online environment for users and foster e-commerce, ensuring that users have IT skills, leading by example through the provision of government information and services online, and encouraging businesses and the community to get online. The third section considers two core issues for the library and information sector in the new economy, i.e. how it will improve current business activities, and how it will take advantage of new business opportunities. The fourth section describes the challenges ahead for the library community, including attracting a broader cross section of the community into the library, allocating staff time and resources, training staff, and providing access to standard computer applications (e.g., word processing, spreadsheets) as well as the Internet. The fifth section outlines necessary IT education and skills. (MES)

3. m-Learning: Positioning Educators for a Mobile, Connected Future

Author

Peters, Kristine

Abstract

Mobile learning is variously viewed as a fad, a threat, and an answer to the learning needs of time-poor mobile workers, so does it have a place in delivering mainstream learning? Based on a 2005 comparative research project, commissioned by the Australian Flexible Learning Framework, the paper reports on research into Web-based information about the use of mobile technologies for commerce and learning, which was then tested through 29 interviews with manufacturers of mobile devices, businesses and education providers. The research found that mobile technologies were in common use in some commercial sectors, but their use purely for learning was rare. m-Learning lends itself to new methods of delivery, however, that are highly suited to the "just enough, just in time, and just for me" demands of 21st Century learners.

Abstract

With recent advances in information technologies such as global position system and mobile internet, a huge volume of spatio-textual objects have been generated from location-based services, which enable a wide range of spatial keyword queries. Recently, researchers have proposed a novel query, called Spatial Pattern Matching (SPM), which uses a pattern to capture the user's intention. It has been demonstrated to be fundamental and useful for many real applications. Despite its usefulness, the SPM problem is computationally intractable. Existing algorithms suffer from the low efficiency issue, especially on large scale datasets. To enhance the performance of SPM, in this paper we propose a novel Efficient Spatial Pattern Matching (ESPM) algorithm, which exploits the inverted linear quadtree index and computes matched node pairs and object pairs level by level in a top-down manner. In particular, it focuses on pruning unpromising nodes and node pairs at the high levels, resulting in a large number of unpromising objects and object pairs to be pruned before accessing them from disk. We experimentally evaluate the performance of ESPM on real large datasets. Our results show that ESPM is over one order of magnitude faster than the state-of-the-art algorithm, and also uses much less I/O cost. [ABSTRACT FROM AUTHOR]
