Exploring novice users' training needs in searching information on the World Wide Web.
Searching for information on the WWW involves locating a website and locating information on that site. A recent study implied that novice users' training needs exclusively relate to locating websites. The present case study tried to reveal the knowledge and skills that constitute these training needs. Fourteen pre-university students, classified as novice (n = 7) or experienced WWW-user (n = 7) performed three web search tasks. Their actions and verbalisations were recorded. Between-group compa
Can kindergarten children be successfully involved in probabilistic tasks?
This paper describes a classroom teaching experiment, concerning the concept of probability, with children aged 5 in a kindergarten school. The teaching experiment was based on constructivist and interactionist theories about the learning of school mathematics and lasted one month. The collection of the information was based on the tape-recorded interviews with the children (each child was interviewed prior to the research program, at the end of the program and one month later) and the videotape
An innovative teaching and learning environment for school mathematics
The paper presents the main characteristics, the background reference, and educational aims of an innovative teaching and learning environment designed and implemented for promoting arithmetic problems solving skills in children of compulsory school. The project is partially funded by the European Community Research and Development Project ITALES "Innovative Teaching and Learning Environments for Schools" (IST 2000-23356). The research addresses a sector (that of arithmetic problem solving) whi
Determining the Sources of Delay in a Distributed Learning Environment
In the context of LeGE-WG we expect to see the Open Grid Services Architecture (OGSA) being used as a guiding framework for the future deployment of Distributed Learning Environment (DLEs). OGSA is totally service-oriented and it has been known for sometime that Quality of Service (QoS) is key to the success of DLEs. Delay in particular, as experienced by the end user, is one of the key QoS parameters for a DLE. This paper describes techniques for identifying sources of such delay, and a model f
Personalisation Services for Self e-Learning Networks
This paper describes the personalisation services designed for self e-learning networks in the SeLeNe project. A self e-learning network consists of web-based learning objects that have been made available to the network by its users, along with metadata descriptions of these learning objects and of the network's users. The proposed personalisation facilities include: querying learning object descriptions to return results tailored towards users' individual goals and preferences; the ability to
A Model for Interoperability in Computer Supported Collaborative Learning
Computer Supported Collaborative Learning activities involve combination of complex software tools that often need to interoperate in a wider context of learning. This paper proposes a data model that accommodates requirements of typical collaborative learning situations and facilitates interoperability of tools and interchange of products of collaboration and evaluation data. The model has been tested against various typical tools used for both synchronous and asynchronous collaboration of grou
An Advisory QoS Service for GRID Based Learning Environments
This paper argues that the assumption of end-to-end QoS provision for use in Grid based applications is unsafe. We present an architecture which provides an adaptive QoS service for GRID applications which are prepared to adapt rather than assume the best and then suffer the worst. This is particularly relevant to Internet based GRIDs. An example application from the field of collaborative learning environments is given, featuring adaptive QoS for Real Time Protocol (RTP) based audio and visual
Futurelab: Personalisation and Digital Technologies
The 'Personalisation and Digital Technologies' report moves the personalisation debate forward by focusing specifically on the potential of digital technologies in four key areas: enabling learners to make informed educational choices; diversifying and acknowledging different forms of skills and knowledge; creating diverse learning environments; and developing learner-focused forms of assessment and feedback. The report also contains a Learner's Charter, which sets out a series of entitlements t

Tutorial planning : Adapting course generation to todays needs.
Most of today's course generation does not allow an in-depth, generic representation of pedagogical knowledge. However, supporting individual learners with different goals requires an elaborate representation of pedagogical expertise. In this paper, I describe a framework that adapts existing approaches for representing and using pedagogical knowledge to meet today's needs. Furthermore, I will show how in this framework several of today's problems are solved, such as the integration of distribut
Networked Learning, a relational approach weak and strong ties.
In this paper, we explore the idea of weak ties in networked learning. We go back to the original conception of the strength of weak ties (Granovetter 1973) and relate this to a dialogic understanding of networked learning (Koschmann 1999, Dysthe 2002). These theoretical ideas are applied to the examination of two networked settings in which educational leaders exchange ideas and have the potential to create knowledge. We examine these networks from the point of view of the overall pattern of in
Semantic Learning Model and Extended Student model: towards an AHAM-based adaptive system
In adaptive hypermedia systems, we distinguish AHAM as the most popular reference model which is based on the Dexter model. Our work consists on building an adaptive system following this model. In this paper, we deal both with the domain and the user's model. On one hand, the domain model called Semantic Learning Model (SLM) is described taking into account the pedagogical structure resulting from our pedagogical segmentation process. On the other hand, our user's model called eXtended Student
Semantic Annotation for Learning Material
This paper aims at providing the specification for semantic annotation tools for e-learning. From the specific requirements of annotating learning material, we categorize and evaluate the existing annotation tools, mainly general purpose ones. We illustrate two research prototypes of annotation tools we developed, and evaluate to what extend the specific requirements of annotating learning material are reached by these research prototypes.

Auburn vs. Clemson (1954)
"The triumph was another team victory for the Plainsmen as they chalked up their fourth win in a row. Hoppy Middleton, with three first half touchdowns, lead the Auburn Tigers to a smashing 27 to 6 decision over Clemson before a Homecoming crowd of 24,000. Although the game was marred by a constant flow of penalties, the Plainsmen left no doubt of their superiority in the minds of Coach Frank Howard's elevens. The Auburn forward wall deserved much credit for the decisiveness of the victory. They
Helping Students to Write With Clarity
Most of us can benefit from a second set of eyes reading something we write. At Penn, there’s a place to go to get constructive criticism for everything from a research paper written for a course to an article penned for a peer review journal. The Marks Family Writing Center, part of the Critical Writing Program in Penn’s Center for Programs in Contemporary Writing, gives students the kind of individual attention and feedback needed to write with clarity. Established in 2009 through a g

A National Study of Chronic Disease Prevalence and Access to Care in Uninsured U.S. Adults
Background: No recent national studies have assessed chronic illness prevalence or access to care among persons without insurance in the United States. Objective: To compare reports of chronic conditions and access to care among U.S. adults, by self-reported insurance status. Design: Population-based survey. Setting: National Health and Nutritional Examination Survey (1999–2004). Participants: 12 486 patients age 18 to 64 years. Measurements: Estimates of national rates of cardiovascular d
Confronting Health Inequity: The Global Dimension
Since the days of Hippocrates, health inequities and the role of social and environmental factors in the determination of marked differences in health status have been well recognized. For some time now, the driving force behind public health has been understanding and intervening in the underlying causes of health inequity. The publication of the Black Report1 in the United Kingdom in 1980 brought a more focused approach to this discourse by identifying specific factors, such as social class, g
