Faculty authoring of course-specific software for disadvantaged nursing students using LinkWay: a case study.

This article adds to the literature on the use of hypermedia systems for software development in nursing education by describing design and authoring considerations in the construction of course-specific remediating software. In 1991, under the guidance of an instructional designer, faculty members developed LinkWay folders on aspects of the endocrine system for remedial use by students in Project Get Ahead in Nursing at Southern Illinois University at Edwardsville. Existing content outlines were modified according to design criteria, including representing information graphically, making the software translation interactive, embedding visual prompts and cues, and conforming to a specific design protocol. The use of LinkWay in facilitating the implementation of both procedural of both procedural and screen protocol is discussed, and several screen templates are presented, including menus, multiple choice, short answer, multiple choice browsing, and end-of-section evaluation. Current project status and conclusions for remediation using a hypermedia approach are discussed.

Diffusion of innovations: anatomical informatics and iPods.

Over the course of many centuries, evolving scientific methods and technologies have advanced the study of anatomy. More recently, such dissemination of innovations has been formally studied in multidisciplinary psychosocial contexts, yielding useful knowledge about underlying principles and processes. We review these precepts and show how diffusion of innovations theory and principles apply to the development and dissemination of anatomical information methods and resources. We consider the factors affecting the late-20th-century dissemination of personal computers and World Wide Web hypermedia into widespread use in anatomical research and instruction. We report on the results of a small experiment in applied diffusion, the development and Internet-based distribution of learning resources for a popular, widely distributed personal media player. With these wearable microcomputer devices already in use by a variety of students, new opportunities exist for widespread dissemination of anatomical information. The continuing evolution of wearable computing devices underscores the need for maintaining anatomical information transportability via standardized data formats.

Desirable attributes of public educational websites.

Certain attributes are particularly desirable for public educational websites, and websites for ethics education in particular. Among the most important of these attributes is wide accessibility through adherence to the World Wide Web Consortium (W3C) standards for HTML code. Adherence to this standard produces webpages that can be rendered by a full range of web browsers, including Braille and speech browsers. Although almost no academic websites, including ethics websites, and even fewer commercial websites are accessible by W3C standards, as illustrated by the Online Ethics Center for Engineering and Science , even websites created on limited budgets and with an undergraduate student staff can fulfill these standards. Other desirable attributes, such as provision of annotation for all links and the use of annotated links to give the user alternate ways of ordering and organizing content, are important for making full use of the educational possibilities of hypermedia for websites.

Distance learning, problem based learning and dynamic knowledge networks.

This paper is an attempt to develop a distance learning model grounded upon a strict integration of problem based learning (PBL), dynamic knowledge networks (DKN) and web tools, such as hypermedia documents, synchronous and asynchronous communication facilities, etc. The main objective is to develop a theory of distance learning based upon the idea that learning is a highly dynamic cognitive process aimed at connecting different concepts in a network of mutually supporting concepts. Moreover, this process is supposed to be the result of a social interaction that has to be facilitated by the web. The model was tested by creating a virtual classroom of medical and nursing students and activating a learning session on the concept of knowledge representation in health sciences.

Embedding a pedagogical model in the design of an online course.

The importance of course design and its relationship to learning is overlooked when the electronic version of a course is static. The author discusses the process used to redesign a traditional course into a dynamic and interactive Web-based course by using a pedagogical model developed specifically for hypermedia. Congruence between the instructional methods and the media is a must for a successful design that meets the needs of a wide variety of learners. The hyperlearning model, Dimensions, provides the infrastructure to facilitate the congruence of methods and media while supporting multiple learning styles.

Hyperad: augmenting and visualizing free text radiology reports.

Hyperad is an automated computer system designed to extract key concepts from thoracic radiology reports and give physicians access to a large database containing the reports and key concepts. The concepts are extracted from textual documents with natural language processing techniques, then stored with the original documents in the database, which can be queried in terms of findings or associated attributes from an intuitive and easily accessible interface. The extracted concepts are represented both textually in a coded hypertext format and graphically on a coronal cross-sectional anatomy atlas, an idealized graphical model of human anatomy. To facilitate implementation, the communication protocols and standards of the World Wide Web (Web) were adopted. The reports and associated forms are encoded in standard hypertext markup language, which makes it possible to use hypermedia links to navigate the Hyperad database with any graphical Web browser. In the future, Hyperad may prove useful for other applications.

[Multimedia methods for the teaching of pharmacology].

Pharmacology is by definition a subject of integration. Students take on a passive role during the learning process and do not count with image aids that could foster understanding, fixation and evocation. Therefore, a hypermedia pharmacology CD ROM program was developed. Such a program includes the following features: hypertext format set up as a network of nodes and arcs, multimedia technology, highly interactive and customized navigation. The prototype thoroughly develops cholinergic neurotransmission pharmacology in its historical, anatomic, physiological, biochemical, pharmacological and therapeutic aspects. The program is divided into three modules; namely, information, exercises and evaluation. Each network node may contain a text, hypertext, images, 3D animation and experimental videos. Information resources include the navigation conceptual map for the chosen node, a track record to go back or forward immediately, the possibility of adding text or images, a text search function, images, animation and videos to find such objects in the different nodes together with the possibility of printing any of the contents. Apart from the information framework, the model has manifold useful integration exercises to assess the learning improvement and prompt the student accordingly to review the topic whenever mistakes exceed a certain amount. This program promotes knowledge integration and building through association of contents. To access to the program's demo, consult the following page.

Formalising and acquiring model-based hypertext in medicine: an integrative approach.

Combining a knowledge acquisition methodology with a powerful data model we present an approach to the acquisition, maintenance and browsing of scientific medical hypertext. The hypergraph-based data model supports the consistent treatment of cyclic data structures, the nesting of complex object and provides an elegant way of path declaration to represent time-dependent medical processes or large hypertext tours. It encourages a stepwise schema design and therefore supports a spiral-shaped acquisition process. We formally define view mechanisms on the basis of a rule-based query and modification language. The views enable a context-sensitive presentation of medical knowledge according to the informational needs of the physician. Our approach has been applied to the implementation of an authoring and tutoring environment for a computer-based hypermedia reference book for cerebrovascular diseases (NeuroN). During the acquisition process the expressive power and flexibility of the representational formats have been evaluated.

Web-based continuing medical education (I): field test of a hybrid computer-mediated instructional delivery system.

BACKGROUND: The Internet and the World Wide Web (the Web) present exciting new possibilities for distributing educational materials at a distance and facilitating collaborative learning among geographically isolated physicians. This article provides a brief overview of the Web as an instructional delivery platform and discusses its strengths and weaknesses as a potential medium for enhancing distance learning opportunities for rural and remote physicians. It also describes an innovative hybrid instructional delivery model that was field tested by the Telemedicine Centre to determine its efficiency and effectiveness for providing Web-based instruction. A hybrid model merges the Web and CD-ROMs (compact disk read-only memory) to use several of the more valuable instructional components of Web-based education (i.e., multimedia, interactive forms, hypermedia, and computer-mediated communications). The results of the field test indicate that the hybrid delivery model was an efficient means for delivering computer-mediated continuing medical education instruction on dermatologic office procedures to a group of rural physicians in low telecommunication bandwidth regions.

Evaluating the efficacy of tele-cognitive rehabilitation for functional performance in three case studies.

Traumatic brain injury (TBI) is one of the main causes of long-term disability, and its rehabilitation is a challenge to the healthcare team. Tele-rehabilitation, through using advancements in networking and tailor-made software, has been developed and applied to the cognitive rehabilitation of persons with brain injury in the present study. Tele-cognitive rehabilitation uses customized online computer software as a treatment mode. The online treatment software is operated on an interactive tele-communication platform--for example, video conferencing with screen sharing. Through implementing the tele-cognitive rehabilitation activities, therapists can help clients to practise and thus improve their cognitive skills through using the treatment software successfully. Moreover, hypermedia programming techniques allow the therapist to adjust the software to meet the client's treatment needs, so that the treatment is appropriate to his/her functional levels and living environment. Also the software can customize immediate visual, auditory and personalized feedback to motivate the client and training can be set at the right pace for the client's needs. The present study aimed to evaluate the effectiveness and perceived efficacy of the newly developed customized tele-cognitive rehabilitation programme for three subjects with traumatic brain injury through using single-case and qualitative research design. The cognitive factors investigated in this pilot study were, respectively, Chinese word recognition, prospective memory and semantic memory. The subjects had undergone a recruitment process with stipulated screening criteria. A single case experimental design (ABA reversal/withdrawal design) consisted of a no-intervention baseline phase (A), an intervention phase (B) and a no-intervention withdrawal phase (A). There were six sessions in each phase, making a total of 18 sessions. Tele-cognitive rehabilitation software was tailor-made according to each subject's cognitive functional needs. To monitor the change in cognitive functions, variables were tapped by tailor-made assessment and qualitative questionnaires through interviews, and they were then used to explore subjects' opinions of the programme and to test the treatment efficacy of the tele-cognitive rehabilitation programme. Finally, the relationships among the three phases were analysed through visual analysis and trend line analysis by means of the split-middle method. The three persons with brain injury showed improving trends and levels of specific cognitive performance during the treatment phase. Qualitative findings were analysed and confirmed the efficacy of the treatment module. The tele-cognitive rehabilitation approach was well received by subjects. The authors suggest that further replication studies of this kind should be conducted in the future and that more subjects should be recruited to improve the generalizability of the results.

Changing surgical education strategies in an environment of changing health care delivery systems.

Emerging changes in health care delivery will have a significant impact on the structure of surgical education in academic departments of surgery. Based on some assumptions as to the probable nature of the final product of this reform, this article encourages a proactive stance by surgical educators to anticipate changes and move toward restructuring in areas of curricular content, the teaching process, performance evaluation strategies, and faculty infrastructure of the academic department. Curriculum changes must bridge the gap between public health and medicine and continue the aggressive trend toward teaching in the outpatient setting. Surgical educators must adapt to evolving computer and instructional technology that will make multimedia presentations, distance education, teleconferencing, hypermedia, and virtual reality commonplace in the teaching setting. Increased emphasis on accountability and accreditation will require stringent criteria in performance and program evaluation methodology. The academic infrastructure will need to adapt to the changing goal of training more general surgeons and fewer specialists and yet maintain the fundamental responsibility of an academic surgeon for mentoring the medical student and surgical resident.

The use of graphic design in an interactive computer teaching program.

The widespread diffusion of affordable computers into the scientific and educational community has provided the opportunity to design medical and scientific teaching programs illustrated either by hand or by utilizing commercially available software and manipulating existing computer generated images. The medical illustrator can provide the ideal aesthetic link between text format information and the visual representation of such knowledge in a concise presentation format. The availability of interactive multimedia programs has given the medical illustrator an environment to create and enhance Hypermedia designed specifically for the purpose of medical education. This paper will focus on the incorporation of illustration and screen design into "CT The Game," an experimental medical teaching program currently being developed in the Johns Hopkins Body CT Imaging Laboratory. The program is designed to provide an enjoyable approach to learning Computed Tomography (CT), and is directed toward an audience of medical students, residents, and fellows.

Design of workcards for aircraft inspection.

The workcard is the primary document that controls an aircraft inspection task and serves as a major factor influencing inspection performance. The present study develops a methodology for design of workcards, based on the application of human factors knowledge to the analysis of aircraft inspection tasks. A taxonomy for design of usable documentation was developed using four basic categories: information readability, information context, information organization, and physical handling/environmental factors. Within the framework of this taxonomy two extreme representative conditions of aircraft inspection tasks, the A-check and the C-check, were analysed for usability. Issues for workcard redesign were identified within the taxonomy using data from user responses. These were then used to develop alternative design solutions offering improved usability. The increase in usability was measured using inspections of DC-9 aircraft, and proved significant. Not only does this study propose specific design solutions, it also provides a generic methodology that can be followed for design of quality documentation for other aircraft inspection tasks. This methodology is currently being extended for the design of usable information for automated workcards and hypermedia-based documentation.

Knowledge-based system for the automated solid-phase extraction of basic drugs from plasma coupled with their liquid chromatographic determination. Application to the biodetermination of beta-receptor blocking agents.

Techniques for the preparation of biological samples are often based nowadays on solid-phase extraction (SPE). The different SPE steps can be performed automatically on disposable extraction cartridges (DECs) by means of a sample processor. A knowledge-based system was developed to facilitate the development of fully automated methods for the solid-phase extraction of relatively hydrophobic basic drugs from plasma, coupled with their determination by high-performance liquid chromatography (HPLC). The DEC filled with 50 mg of cyanopropyl-bonded silica phase is first conditioned with methanol and buffer solution (pH 7.4). After sample application, the DEC sorbent is washed with the same buffer. The analytes are then desorbed with an appropriate eluent and the eluate is finally diluted with the same buffer as used in the HPLC mobile phase before injection. Under these conditions, only three variables are still to be optimized: the composition and volume of the elution solvent and the volume of buffer to be added to the eluate. On the basis of this general strategy, a decision tree providing information about suggested starting conditions and guidelines for the optimization of the three variables was developed and implemented by use of a hypermedia software. This didactic expert system was evaluated using several beta-receptor blocking agents as model compounds and the operating conditions obtained for the automated SPE of these compounds are presented. A method for the determination of propranolol in plasma using the SPE conditions deduced from the knowledge-based system was validated. The absolute recovery of propranolol is ca. 93% and the limit of detection is 1.3 ng ml-1. The mean within-day and between-day reproducibilities are 2.3 and 3.6%, respectively.

A veterinary anatomy tutoring system.

A veterinary anatomy tutoring system was developed by using Knowledge Pro, an object-oriented software development tool with hypermedia capabilities, and MS Access, a relational database. Communication between them is facilitated by using the Structured Query Language (SQL). The architecture of the system is based on knowledge sets, each of which covers four different descriptions of an organ, namely gross anatomy (general description), gross anatomy (comparative features), histology, and embryology, which constitute the knowledge units. These knowledge units are linked with three global variables that define the animals, the topographies, and the system to which this organ belongs, creating three data-bases. These three data-bases are interrelated through the organ field in order to establish a relational model. This system allows versatility in the student's navigation through the information space by offering different modes for information location and presentation. These include course mode, review mode, reference mode, dissection mode, and comparison mode. In addition, the system provides a self-evaluation mode.
