Motivational Influences of Using Peer Evaluation in Problem-Based Learning in Medical Education
This study investigates the ways in which medical students’ achievement goal orientations (AGO) affect their perceptions of learning and actual learning from an online problem-based learning environment, Calibrated Peer ReviewTM. First, the tenability of a four-factor model (Elliot & McGregor, 2001) of AGO was tested with data collected from medical students (N = 137). Then, a structural regression model relating the factors of AGO to students’ perceptions of grading fairness, judgments of learning, and scoring accuracy was tested. The results indicate that student engagement and success in diagnosing a patient’s presentation using a peer feedback-rich web-based PBL environment is somewhat dependent on student motivation. Theoretical and practical implications, in terms of problem-based learning environments in medical education, are discussed
A framework for the design of usable electronic text
This thesis examines the human issues underlying the design and usability of electronic
text systems. In so doing it develops a framework for the conceptualisation of these
issues that aims to guide designers of electronic texts in their attempts to produce usable
systems.
The thesis commences with a review of the traditional human factors literature on
electronic text according to three basic themes: its concern with perceptual,
manipulatory and structural issues. From this examination it is concluded that
shortcomings in translating this work into design result from the adoption of overly
narrow uni-disciplinary views of reading taken from cognitive psychology and
information science which are inappropriate to serve the needs of electronic text
designers.
In an attempt to provide a more relevant description of the reading process a series of
studies examining readers and their views as well as uses of texts is reported. In the
first, a repertory grid based investigation revealed that all texts can be described in
reader-relvant terms according to three criteria: why a text is read, what a text contains
and how it is read. These criteria then form the basis of two investigations of reader-text
interaction using academic journals and user manuals.
The results of these studies highlighted the need to consider readers' models of a
document's structure in discussing text usability. Subsequent experimental work on
readers' models of academic articles demonstrated not only that such models are
important aspects of reader-text interaction but that data of this form could usefully be
employed in the design of an electronic text system.
The proposed framework provides a broad, qualitative model of the important issues
for designers to consider when developing a product It consists of four interactive
elements that focus attention on aspects of reading that have been identified as central to
usability. Simple tests of the utility and validity of the framework are reported and it is
shown that the framework both supports reasoned analysis and subsequent prediction
of reader behaviour as well as providing a parsimonious account of their verbal
utterances while reading. The thesis concludes with an analysis of the likely uses of
such a framework and the potential for electronic text systems in an increasingly
information-hungry world
Assessing computer -mediated communication discourse of a traumatic brain injury survivor
Speech-language pathologists and audiologists have begun using computer technology for information storage and retrieval and as one means of providing clinical services to communication-disordered patients. The purpose of this study is to develop a protocol to assess the written communication of brain-injured clients whose communication therapy milieu includes interactions with the world outside the treatment room through computer-mediated communication (CMC).;A panel of experts reviewed a series of discourse analysis procedures and rated their perceptions of validity, reliability, and ease-of use for the procedures as means of evaluating CMC discourse. The Computer-Mediated Communication Evaluation Protocol (CMC-EP) was developed based on the results of the analysis of the panel ratings and a post-rating consensus inquiry.;A series of e-mail messages and on-line text chats generated over a period of three years were evaluated using the CMC-EP. The results of the CMC-EP were examined to determine if patterns of change were revealed in the CMC discourse of a traumatic brain injury. The CMC-EP consists of four procedures: T-unit analysis, cohesion analysis, Correct Information Unit analysis, and three scales of the Rating of Communication Behaviors. Using the CMC-EP enables speech-language pathologists to complete surface/sentential analysis, cohesion analysis, informational analysis, and conversation analysis of CMC discourse
The Next Frontier in Communication and the ECLIPPSE Study: Bridging the Linguistic Divide in Secure Messaging
abstract: Health systems are heavily promoting patient portals. However, limited health literacy (HL) can restrict online communication via secure messaging (SM) because patients’ literacy skills must be sufficient to convey and comprehend content while clinicians must encourage and elicit communication from patients and match patients’ literacy level. This paper describes the Employing Computational Linguistics to Improve Patient-Provider Secure Email (ECLIPPSE) study, an interdisciplinary effort bringing together scientists in communication, computational linguistics, and health services to employ computational linguistic methods to (1) create a novel Linguistic Complexity Profile (LCP) to characterize communications of patients and clinicians and demonstrate its validity and (2) examine whether providers accommodate communication needs of patients with limited HL by tailoring their SM responses. We will study >5 million SMs generated by >150,000 ethnically diverse type 2 diabetes patients and >9000 clinicians from two settings: an integrated delivery system and a public (safety net) system. Finally, we will then create an LCP-based automated aid that delivers real-time feedback to clinicians to reduce the linguistic complexity of their SMs. This research will support health systems’ journeys to become health literate healthcare organizations and reduce HL-related disparities in diabetes care.The article is published at https://www.hindawi.com/journals/jdr/2017/1348242
Measurement Properties of Visual Analogue Scale, Numeric Rating Scale, and Pain Severity Subscale of the Brief Pain Inventory in Patients With Low Back Pain:A Systematic Review
Visual Analogue Scale (VAS), Numeric Rating Scale (NRS), and Pain Severity subscale of the Brief Pain Inventory (BPI-PS)] are the most frequently used instruments to measure pain intensity in low back pain (LBP). However, their measurement properties in this population have not been systematically reviewed. The goal of this study was to provide such systematic evidence synthesis. Six electronic sources (MEDLINE, EMBASE, CINAHL, PsycINFO, SportDiscus, Google Scholar) were searched (July 2017). Studies assessing any measurement property in patients with non-specific LBP were included. Two reviewers independently screened articles and assessed risk of bias using the COSMIN checklist. For each measurement property: evidence quality was rated as high, moderate, low, or very low (GRADE approach); results were classified as sufficient, insufficient or inconsistent. Ten studies assessed the VAS, 13 the NRS, four the BPI-PS. The three instruments displayed low or very low quality evidence for content validity. High quality evidence was only available for NRS insufficient measurement error. Moderate evidence was available for: NRS inconsistent responsiveness, BPI-PS sufficient structural validity and internal consistency, and BPI-PS inconsistent construct validity. All VAS measurement properties were underpinned by no, low or very low quality evidence, likewise the other measurement properties of NRS and BPI-PS
Applied Evaluative Informetrics: Part 1
This manuscript is a preprint version of Part 1 (General Introduction and
Synopsis) of the book Applied Evaluative Informetrics, to be published by
Springer in the summer of 2017. This book presents an introduction to the field
of applied evaluative informetrics, and is written for interested scholars and
students from all domains of science and scholarship. It sketches the field's
history, recent achievements, and its potential and limits. It explains the
notion of multi-dimensional research performance, and discusses the pros and
cons of 28 citation-, patent-, reputation- and altmetrics-based indicators. In
addition, it presents quantitative research assessment as an evaluation
science, and focuses on the role of extra-informetric factors in the
development of indicators, and on the policy context of their application. It
also discusses the way forward, both for users and for developers of
informetric tools.Comment: The posted version is a preprint (author copy) of Part 1 (General
