Predicting The Performance Of Interpreting Instruction Based On Digital Propensity Index Score In Text And Graphic Formats

Norman, David 01 January 2008 (has links)
Practitioners have proposed that Digital Natives prefer graphics while Digital Immigrants prefer text. While Instructional Design has been extensively studied and researched, the impact of the graphical emphasis in instructional designs as it relates to digital propensity has not been widely explored. Specifically, this study examined the performance of students when presented with text-only and graphic-only instructional formats. The purpose of this study was to test the relationship between Digital Propensity Index scores of individuals and their performance when interpreting online instruction. A sample of students from the population of a large metropolitan university received the Digital Propensity Index questionnaire, which is a measure of an individual's time spent interacting with digital media. Each student was randomly assigned varying formats of a computer-based instructional unit via a public survey. The instructional unit consisted of the DPI questionnaire and six tasks related to the Central Florida commuter rail system. Participants were asked to answer the DPI questionnaire on a website by clicking on a link in an emailed invitation. Following the DPI questionnaire, participants were randomly assigned to one of two groups. Group One saw three instructional tasks shown in text and shuffled in random order. Each task was displayed on its own webpage. By submitting an answer to the task, the group progressed through the website to the next task. Group Two saw graphic tasks first, again, shuffled in random order. After the first three tasks, the groups swapped instructional formats to view the opposing group's initial questions. Participants were timed on how many seconds they spent reviewing each task. Each task had an assessment question to evaluate the learning outcomes of the instructional unit. Finally, the DPI score of the participant was matched with the time spent viewing each presentation format. The findings indicate that DPI score had a statistically significant prediction of time spent navigating each type of instruction. Though the link between DPI score and time spent navigating instruction was statistically significant, the actual measurable time difference between navigating text and graphic formats was only a fraction of a second for each increment in DPI score. Limitations and potential future research related to the study are discussed as well.

Guider la pratique et la formation éthique des professionnels de la santé : établir les fondements du modèle de la déontologie réflexive (MDR)

Potvin, Marie-Josée 03 1900 (has links)
Si l’approche par compétences au Canada et aux États-Unis est particulièrement valorisée pour orienter la pratique des professionnels de la santé (PDS) – et en bioéthique clinique –, les travaux permettant de mieux comprendre les fondements psychologiques, ontologiques et philosophiques de ces compétences sont peu présents dans la littérature en bioéthique. Les principaux outils actuellement disponibles se divisent généralement en quatre principales catégories : 1) les documents officiels (codes de déontologie, règlements institutionnels, etc.); 2) les principales théories éthiques (éthique de la discussion, éthique de la vertu, principisme, etc.); 3) les ouvrages de référence scientifiques; 4) les outils de prise de décision éthique. Ces documents sont des incontournables pour les bioéthiciens et les PDS, mais leur disparité, voire leur contenu parfois contradictoire, jumelée à une compréhension limitée de l’éthique, est souvent source de confusion dans les processus décisionnels et peut être la cause de comportements ne répondant pas aux standards éthiques des pratiques professionnelles. Notre recherche constitue une réflexion qui s’inscrit en amont de ces outils dont le caractère pragmatique a le désavantage de simplifier la réflexion théorique au profit de données plus concrètes. Nos travaux visent à développer les bases d’un modèle flexible et inclusif – le modèle de la déontologie réflexive (MDR) – permettant de : 1) poser les principaux repères philosophiques, sociaux et déontologiques des problématiques éthiques rencontrées en pratique; 2) saisir les principales tensions éthiques inhérentes à cette complexité; 3) mieux comprendre, dans une perspective psychologique et développementale, les exigences personnelles et professionnelles qu’impose le statut de professionnel de la santé dans le contexte actuel des soins de santé. Entreprise théorique, ce projet consiste principalement à mettre en relation dynamique un ensemble de dimensions (légale, éthique, clinique, sociale, psychologique) à l’oeuvre dans la rencontre du bioéthicien et du PDS avec la complexité des situations éthiques, en s’inspirant du concept de sensibilité éthique de la « petite éthique » de Paul Ricoeur (1990), du modèle des quatre composantes de Rest (1994) et de la théorie du soi et des modes identitaires d’Augusto Blasi (1993). Ce processus implique trois étapes successives : 1) une mise en ii perspective de la posture épistémologique particulière du bioéthicien et du PDS à la lumière de la « petite éthique » de Ricoeur; 2) une revue de la littérature interdisciplinaire sur le concept de sensibilité éthique afin d’en proposer une définition et de le mettre en perspective avec d’autres compétences éthiques; 3) le développement d’un cadre de référence en matière d’identité éthique professionnelle (professional ethics identity tendencies, PEIT), inspiré de la théorie du soi et des modes identitaires de Blasi. Ces PEIT proposent un repère normatif aux exigences liées à la construction de l'identité en contexte de pratique des PDS et suggèrent des pistes de réflexion quant à la formation et à la recherche en éthique professionnelle. Cette recherche souhaite établir des fondements théoriques pour le développement ultérieur du modèle de la déontologie réflexive (MDR). / If the competency approach seems to be particularly valorised in Canada and in the United States for orienting the practice of health care professionals (HCP) – and in clinical bioethics – material that could provide with a better understanding of the psychological, ontological and philosophical foundations of these competencies seems rather limited in the bioethical literature. The tools that are generally available can be divided into four main categories: 1) official documents (e.g., code of ethics, institutional policies); 2) the main ethical theories (e.g., virtue ethics, theories of justice, principlism); 3) scientific references (e.g., journals, books); 4) decision-making tools. These documents are important for bioethicists and HCPs, but their disparities and even contradictions, coupled with poor knowledge in professional ethics, may be a significant source of confusion in the decision making process and even lead to behaviour that does not meet the ethical standards of HCP. This thesis is an upstream reflection regarding these tools, whose pragmatic character has the disadvantage of simplifying theoretical reflection at the benefit of more concrete evidence useful for practical decision making. This project aims at developing the foundations for a flexible and inclusive model – a model of deontological reflexivity (MDR) – that will: 1) present the main philosophical, psychological, sociological and deontological landmarks characterising ethical issues encountered in practice; 2) understand, from a psychological and developmental perspective, the personal and professional requirements inherent to the status of the health care professional in the current context of health care. A theoretical enterprise, this project primarily consists in relating, in a dynamic manner, a variety of dimensions (legal, ethical, clinical, psychological) at work in complex ethical situations encountered by HCPs and bioethicists, inspired by the concept of ethical sensitivity, the “petite éthique” of Paul Ricoeur (1990), the self theory along with Blasi's Identity modes (Blasi, 1993). The analysis process will consist in three successive phases: 1) a putting into perspective of the bioethicist's and HCPs’ epistemological posture in light of the “petite éthique” of Paul Ricoeur (1990); 2) an interdisciplinary literature review of “ethical sensitivity” in order to propose a definition of the concept and place it into perspective with other ethical competencies; 3) the development of a framework regarding professional ethics iv and identity (professional ethics identity tendencies, PEIT), inspired both by the self theory and Blasi's Identity modes. These PEITs provide a normative benchmark related to the construction of identity in the health care context and suggest some innovative avenues for professional ethics research and education. This research wish to elaborate the theoretical foundations that will be utilised further in the future to develop the model of deontological reflexivity (MDR).
