The specific procedure shown is the two-way, indwelling Foley catheter. The video covers the patient interview, preparing oneself for the procedure following all universal precautions, preparation of the equipment tray, insertion of the catheter using and maintaining sterile technique, catheter removal and appropriate disposal of all used equip
Towards a Generic Service Oriented Framework for Integrated User Management of Virtual Communities
A central Service layer for the European eLearning Grid Infrastructure (ELeGI) is the one for the management of members and the provision of collaborational services (Virtual Community Services).
Because it is a lot of effort to totally newly (re-)write the collaboration services like e.g. a videoconferencing service, it is much more desirable to take existing applications and just to wrap them with a Web Service interface to programmatically access the existing functionality relevant to user m
The impact of simulator-based instruction on the diagramming of the interaction of light and matter
We examine the conceptual development resulting from an instructional experiment with an interactive learning environment in geometrical optics for introductory high school physics. How did teaching-learning processes come to change the ways in which students depicted various everyday optical situations in paper and pencil graphical representations? We view conceptual development as a process resulting in part from increasingly aligning one's practices to a target community by means of participa
Medical Response to Weapons of Mass Destruction: Nerve Agents

The Climate Visualizer: Sense-Making Through Scientific Visualization
This paper describes the design of a learning environment, called the Climate Visualizer, intended to facilitate scientific sense-making in high school classrooms by providing students the ability to craft, inspect, and annotate scientific visualizations. The theoretical background for our design presents a view of learning as acquiring and critiquing cultural practices and stresses the need for students to appropriate the social and material aspects of practice when learning an area. This is fo
Cyclone in the classroom: bringing the atmospheric science community into the high school
There has been much discussion about the failure of traditional science education to prepare students for careers in science (Halloun & Hestenes, 1985; Rutherford & Ahlgren, 1990). Students may become adept at solving textbook problems, but they fail to apply the theories that are learned in school to the actual phenomena that the theories attempt to explain (Tinker, 1992). This is in large part due to the fact that students don't often experience phenomena in the classroom. They spend most of t
Synthesizing instructional technologies and educational culture: exploring cognition and metacogniti
This research was initiated to examine instructional technologies and educational cultures in relation to identified cognitive and metacognitive strategies uses in school tasks. The project involved activities from the social studies curricula that were presented through two new software programs intended to support the development of problem-solving and reasoning strategies - IDEA [Interactive Decision Envisioning Aid, Pea (76)] Notecards (34) - and through instructional approaches bases upon "
Super Users and Local Developers: The Organization of End User Development in an Accounting Company
The paper presents a case study following the activities of super users and local developers during the adoption of a new business application by an accounting firm in Scandinavia (referred to as the Company). The Company launched a program to train super users to help with this process because of the complexity of the new system, a generic, multi-purpose application system replacing several older, non-integrated systems. The system, Visma Business (VB) is a comprehensive financial and accountin
VCLab as an Example of GRIDifying Virtual Scientific Experiments
This paper describes and summarizes the current state of the development for making the Virtual Control Laboratory (VCLab) a GRID application within the ELeGI project. It introduces shortly into GRID techniques and shows how this GRIDifying process is performed to offer virtual scientific experiments (VSE) on the GRID.
The architecture and some technical details of the prototype implementation are presented. The next steps in the development are outlined concerning the collaboration aspects of
Gathering Requirements for a Grid-based Automatic Marking System
This paper reports on our experiences using a Creative Requirements [1] workshop approach to elicit requirements for a Grid-based automatic marking system. The research was conducted for ELeGI, an EU funded project whose goal is to provide a European Learning Grid infrastructure to promote a learning paradigm shift from a teacher-centred approach to a learner-centred approach.
The automatic marking system uses Latent Semantic Analysis (LSA) to assess the meaning of essays written by computer sc
Experiences with Writing Grid Clients for Mobile devices
This paper describes our attempts to write GRID clients for Mobile Devices, such as a PDA, which have restrictive computational and storage facilities. Our experiences are based on an implementation of a mobile GRID client for Finesse, an existing web-based e-learning system.
At this stage of our work we are not looking to novel applications of mobile learning, but rather are exploring the feasibility of mobile devices as GRID platforms, with novel learning applications as our future aim. We ex
A Grid Services Implementation for a Virtual Research Environment
In the past, virtual learning and research environments have typically been implemented as monolithic systems. Current research focuses on creating such environments from selected Grid and Web services.
In this paper we describe the Virtual Orthopaedic European University, which was created to support Higher Surgical Trainees to provide evidence for their learning contracts by carrying out experiments and publishing the results.
We use this environment as a case study for the re-implementation
edCity - a New Learning Environment
edCity will facilitate learning anywhere, anytime, for anyone - for users of all ages both in traditionally taught and in pedagogically innovative courses - by fusing physical and virtual representations of real cities in order to provide a new learning framework.
The edCity project will be scenario-driven with major conceptual inputs to the design generated by highly interactive scenario-building activities.
After 18 months, a "Semantic Web" framework will be published and a prototype of the
Creatures of Habit: A Computational System to Enhance and Illuminate the Development of Scientific T
Creatures of Habit is a computer-based microworld designed to engage middle-to-high school students in the process of scientific inquiry. The system depicts a universe of interacting programmable “creatures” whose individual behavior is guided by simple rules that may model naive psychology, physical laws, chemical affinities, and other domains. Students can create or revise creature rules and explore the resulting (and often surprising) emergent behaviors within “artificial ecosystems”;
Technology and pedagogy for collaborative problem solving as a context for learning
This workshop, sponsored jointly by CSCW'92 and the Centre for Applied Cognitive Science at the Ontario Institute for Studies in Education (OISE), was organized to bring together researchers with interests in the emerging area of Computer Support for Collaborative Learning (CSCL). It was held at OISE on the weekend preceding CSCW'92 and was attended by 27 participants from academia and industry.
Children's mental models of recursive logo programs
Children who had a year of Logo programming experience were asked to think-aloud about what brief Logo recursive programs will do, and then to predict with a hand-simulation of the programs what the Logo graphics turtle will draw when the program is executed. If discrepancies arose in this last phase, children were asked to explain them. A prevaient but misguided "looping" interpretation of Logo recursion was identified, and this robust mental model persisted even in the face of contradiction be
Beyond Amplification: Using the Computer to Reorganize Mental Functioning
Computers are classically viewed as amplifiers of cognition. An alternative conceptualization is offered of computer as reorganizer of mental functioning. Software analyses illuminate the advantages of the latter approach for new visions of the potential cognitive benefits of computers. A new result emerges: Because the cognitive technologies we invent serve as instruments of cultural redefinition (shaping who we are by changing, not just amplifying, what we do), defining educational values beco
Integrating Human and Computer Intelligence
The thesis to be explored in this chapter is that advances in computer applications and artificial intelligence have important implications for the study of development and learning in psychology. I begin by reviewing current approaches to the use of computers as devices for solving problems. reasoning, and thinking. I then raise questions concerning the integration of computer-based intelligence with human intelligence to seme human development and the processes of education.
