Online teaching strategies to improve collaboration among nursing students.

Collaborative problem-solving is an essential competency for nurses and all health professionals. This paper compares the design characteristics and educational benefits of three online-teaching strategies that nurse educators can use to build the critical thinking and social skills needed for effective collaboration: computer supported collaborative learning, case-based facilitated discussion, and cognitive flexibility hypermedia. These strategies support a critical instructional outcome required for effective collaboration: the ability to examine, assess, and synthesize multiple perspectives to resolve illstructured problems (i.e., problems for which there is no clear-cut solution). Descriptions, examples, and guidelines for implementing each strategy are provided. By integrating these strategies into their online courses, nurse educators can prepare nurses to work effectively with others to solve complex problems in clinical practice and the broader health-care system.

Multimedia based medical instrumentation course in biomedical engineering.

Computer assisted instruction in education, including biomedical engineering education, has been explored and changed dramatically for more than two decades. The Internet, with its capacity to transmit synchronous and asynchronous audio, text, and graphics, presents educators with tremendous opportunies for distance education and independent learning. In this work, we have developed a new educational hypermedia for medical instrumentation courses. It is designed to be suitable for biomedical and technical curricula where these courses are scheduled. The courseware provides support for the education of medical instrumentation. The work is presented herein to provide multimedia course material with animations to assist learning some key Medical Instrumentation topics on the World Wide Web.

'Ten golden rules' for designing software in medical education: results from a formative evaluation of DIALOG.

Evaluation of educational material has become very important in a climate where there is increasing concern with assessing and maintaining quality. DIALOG (acronym for Distance Interactive Learning in Obstetrics and Gynaecology) is an electronic program on CD-ROM for continuing education. A formative evaluation of DIALOG was carried out to determine whether DIALOG was achieving its educational objectives. The results of the evaluation helped to suggest '10 golden rules' for designing software for the purpose of CPD for medical practitioners. These 'rules' should help in designing future software in medical education. They highlight the importance of content, presentation, design, use of hypermedia and multimedia and reduced cost in order to facilitate appropriate use of such programmes.

The sociocognitive psychology of computer-mediated communication: the present and future of technology-based interactions.

The increased diffusion of the Internet has made computer-mediated communication (CMC) very popular. However, a difficult question arises for psychologists and communication researchers: "What are the communicative characteristics of CMC?" According to the "cues-filtered-out" approach, CMC lacks the specifically relational features (social cues), which enable the interlocutors to identify correctly the kind of interpersonal situations they find themselves in. This paper counters this vision by integrating in its theoretical frame the different psycho-social approaches available in current literature. In particular, the paper describes the characteristics of the socio-cognitive processes-emotional expression, context definition, and identity creation-used by the interlocutors to make order and create relationships out of the miscommunication processes typical of CMC. Moreover, it presents the emerging forms of CMC-instant messaging, shared hypermedia, weblogs, and graphical chats-and their possible social and communicative effects.

The globalization of crystallographic knowledge.

The rapid growth of the World Wide Web provides major new opportunities for distributed databases, especially in macromolecular science. A new generation of technology, based on structured documents (SD), is being developed which will integrate documents and data in a seamless manner. This offers experimentalists the chance to publish and archive high-quality data from any discipline. Data and documents from different disciplines can be combined and searched using technology such as eXtensible Markup Language (XML) and its associated support for hypermedia (XLL), metadata (RDF) and stylesheets (XSL). Opportunities in crystallography and related disciplines are described.

Teaching microbiology with hypertext: first steps towards a virtual textbook.

Computer-assisted learning materials for medical microbiology were developed using hypertext-authoring software (Folio 3.1). Two versions of a text-only introductory tutorial (detailed, read only, and read-write noteform) were then evaluated in a prospective, randomized trial. Evaluation was by pre- and post-exposure multiple choice questions, and by self-administered questionnaire. There was a small difference in outcome between the two groups; the read-write group scoring higher, and students who used either software performed better than those who did not (P = 0.014). Responses to the post-test questionnaires showed that many students regarded the read-only software as an electronic handout, more frequent users requesting the addition of illustrations, self-assessment questions, and greater interactivity. A small group of students made use of the read-write version of the tutorial as a 'virtual textbook' by adding extra material to the starter file. Our experience suggests that the low-cost option of text-only hypermedia produces only modest learning gains for medical undergraduates.

Veterinary education in the era of information technology.

A major innovation in the delivery of the veterinary curriculum is being implemented at The University of Melbourne using the subject of systematic bacteriology and mycology as a pilot project. Students receive course information as interactive, multimedia databases. These consist of text and an associated library of catalogued digital images, movies and sounds. The databases employ a hypermedia information system to achieve efficient integration within and between subjects. The new delivery method encourages greater autonomy and more active learning roles for students than occurs in traditionally taught courses. Students will use their databases as the principal resource of information for undergraduate studies. A unique feature of this system for delivering the curriculum is that students will modify and expand their databases during the course. The ultimate aim is for students at graduation to receive, on disc, a copy of their own databases, adapted by themselves to their particular future professional needs. As graduate veterinarians they will continue to use their databases as a major resource for information and learning, thus providing continuity from undergraduate to continuing postgraduate education.

Ontology driven dynamic linking of biology resources.

Biologists were early adopters of the Web and continue to use it as the primary means of delivering data, tools and knowledge to their community. The Web is made by the links between pages, yet these links have many limitations: they are static and maintained by hand; they can only link one lexical item to another single resource; ownership is necessary for the placement of link anchors and the link mechanism is essentially inflexible. Dynamic linking services, supported by ontologies, offer a mechanism to overcome such restrictions. The Conceptual Open Hypermedia Service (COHSE) system enhances web resources through the dynamic addition of hypertext links. These links are derived through the use of an ontology and associated lexicon along with a mapping from concepts to possible link targets. We describe an application of COHSE to Bioinformatics, using the Gene Ontology (GO) as an ontology and associated keyword mappings and GO associations as link targets. The resulting demonstrator (referred to here as GOHSE) provides both glossary functionality and the possibility of building knowledge based hypertext structures linking bioinformatics resources.

The radiographic signs of arthritis: a computer teaching module.

This article describes the steps involved in production of a computer teaching module on the radiographic diagnosis of arthritis. The module was part of a research project aimed at producing seven computer teaching modules. Several staff radiologists and residents were involved, as well as a consultant on medical education. A generic shell program was used as a frame for all seven modules. The author of each module then filled in the empty pages of the shell with the appropriate text and images, along with additional short program scripts. The module on the radiographic diagnosis of arthritis described and illustrated the basic radiographic signs of arthritis. Practice cases were also included, and interactive and hypermedia features were implemented. The modules were then evaluated by means of task list tests and interviews. The experience was judged to have been successful, although the amount of time spent by some authors was much more than expected.

The World-Wide Web: an interface between research and teaching in bioinformatics.

The rapid expansion occurring in World-Wide Web activity is beginning to make the concepts of 'global hypermedia' and 'universal document readership realistic objectives of the new revolution in information technology. One consequence of this increase in usage is that educators and students are becoming more aware of the diversity of the knowledge base which can be accessed via the Internet. Although computerised databases and information services have long played a key role in bioinformatics these same resources can also be used to provide core materials for teaching and learning. The large datasets and archives that have been compiled for biomedical research can be enhanced with the addition of a variety of multimedia elements (images, digital videos, animation etc.). The use of this digitally stored information in structured and self-directed learning environments is likely to increase as activity across World-Wide Web increases.

A simple method for serving Web hypermaps with dynamic database drill-down.

BACKGROUND: HealthCyberMap http://healthcybermap.semanticweb.org aims at mapping parts of health information cyberspace in novel ways to deliver a semantically superior user experience. This is achieved through "intelligent" categorisation and interactive hypermedia visualisation of health resources using metadata, clinical codes and GIS. HealthCyberMap is an ArcView 3.1 project. WebView, the Internet extension to ArcView, publishes HealthCyberMap ArcView Views as Web client-side imagemaps. The basic WebView set-up does not support any GIS database connection, and published Web maps become disconnected from the original project. A dedicated Internet map server would be the best way to serve HealthCyberMap database-driven interactive Web maps, but is an expensive and complex solution to acquire, run and maintain. This paper describes HealthCyberMap simple, low-cost method for "patching" WebView to serve hypermaps with dynamic database drill-down functionality on the Web. RESULTS: The proposed solution is currently used for publishing HealthCyberMap GIS-generated navigational information maps on the Web while maintaining their links with the underlying resource metadata base. CONCLUSION: The authors believe their map serving approach as adopted in HealthCyberMap has been very successful, especially in cases when only map attribute data change without a corresponding effect on map appearance. It should be also possible to use the same solution to publish other interactive GIS-driven maps on the Web, e.g., maps of real world health problems.

A learning tool in medical imaging: using procedure graphs in radiographic process simulation.

Teaching the procedural elements of imaging protocols and understanding the interrelationships and interdependencies of diagnostic X-ray system parameters and their effects on image quality, are among the main objectives of medical imaging training programs. A teaching tool is designed and implemented to support these goals. Tool design is influenced by hybrid learning system architectures and it is based on a graph approach, which is described. Implementation is carried out using a hypermedia development environment (Toolbook) coupled with a database (Paradox). The core of the system is an attributed priority graph, capable of supporting the organization of the domain knowledge, monitoring of user-machine interaction and managing the user-system dialogue. Use of this approach resulted in an interactive simulation tool, which provides computer aided learning support, to radiology related personnel, such as radiologists and radiographers. The potential value of the tool is not restricted only to didactic tasks, but may include trouble-shooting and documentation.

A framework for the integration of distributed autonomous healthcare information systems.

This paper presents a domain-specific framework for the integration of geographically distributed heterogeneous autonomous healthcare information systems. Integration is seen and understood in terms of access to information resources, and in terms of content, structure, and visualization of patient record segments, with the goal of creating a virtual patient record at the medical workstations. The proposed approach covers integration aspects related to presentation, control, data, and function. The architecture and the components of the framework are based on the newly introduced Patient Meta-Record (PMR) concept, but also make use of existing or emerging standards for distributed object-oriented computing and information presentation. At the application and middle-ware layers of the presented healthcare information systems architecture, the PMR concept enhances or enables services for data mediation, distributed directory access, and workflow management. At the bitways layer, high performance networks provide a fast medium, which is indispensable for medical image distribution, collaborative work, hypermedia library applications, and teleconsultation.

Internet image database: development and implementation.

The widespread acceptance of World Wide Web (WWW) hypermedia protocols allows rapid cross-platform development of database interfaces. Using the WWW as the interface promotes easy integration of databases with other publicly available Internet resources. We present our experience with an image database search program (IDBS) developed on the PC platform using freely available UNIX development tools. The database routines were written in PERL. The image database program provides a familiar user interface to a collection of clinical images stored in digital form, either on local media or on the Internet. The design goals of the project and the strategies used to meet them are presented. The source code and a demonstration database are available on the Internet at http:/(/)www.webmedix.com/idbs.

W.W.W. cooperative multimedia interface in medicine.

The World Wide Web is now the most used multimedia information system on Internet allowing, by means of Web browsers such as Netscape Navigator or Mosaic, distribution or consultation of hypermedia documents. Although the Web has appeared only recently, the growth of its use has generated the emergence of numerous information and knowledge bases in the medical field. We suggest to investigate extended functionalities in order to introduce cooperative activities in our medical information system. These new activities allow asynchronous exchange of records and synchronous cooperation for a better coordination of the work within and between hospitals.

Browsing and querying multimedia report collections.

In this paper a system and new methodologies that enable efficient exploration of distributed collections of multimedia reports are described. A conceptual model for the report and a method to semi-automatically create a hypermedia report network have been defined. The main issues addressed in this project were to exploit the textual component of a report to give a more evident semantic meaning to the data produced during the relative exam and to provide users with new interaction paradigms based on Internet technologies.
