Integration of medical imaging into preclinical anatomy courses is already underway in many medical schools. However, interpretation of two-dimensional grayscale images is difficult and conventional volume rendering techniques provide only images of limited quality. In this regard, a more photorealistic visualization provided by Cinematic Rendering (CR) may be more suitable for anatomical education. A randomized, two-period crossover study was conducted from July to December 2018, at the University Hospital of Erlangen, Germany to compare CR and conventional computed tomography (CT) imaging for speed and comprehension of anatomy. Sixteen students were randomized into two assessment sequences. During each assessment period, participants had to answer 15 anatomy-related questions that were divided into three categories: parenchymal, musculoskeletal, and vascular anatomy. After a washout period of 14 days, assessments were crossed over to the respective second reconstruction technique. The mean interperiod differences for the time to answer differed significantly between the CR–CT sequence (−204.21 ± 156.0 seconds) and the CT–CR sequence (243.33 ± 113.83 seconds; P < 0.001). Overall time reduction by CR was 65.56%. Cinematic Rendering visualization of musculoskeletal and vascular anatomy was higher rated compared to CT visualization (P < 0.001 and P = 0.003), whereas CT visualization of parenchymal anatomy received a higher scoring than CR visualization (P < 0.001). No carryover effects were observed. A questionnaire revealed that students consider CR to be beneficial for medical education. These results suggest that CR has a potential to enhance knowledge acquisition and transfer from medical imaging data in medical education.  相似文献   

Investigating morphological awareness and the processing of transparent and opaque words in adults with low literacy skills and in skilled readers     

Nancy L. To  Elizabeth L. Tighe  Katherine S. Binder 《Journal of Research in Reading》2016,39(2):171-188

For adults with low literacy skills, the role of phonology in reading has been fairly well researched, but less is known about the role of morphology in reading. We investigated the contribution of morphological awareness to word reading and reading comprehension and found that for adults with low literacy skills and skilled readers, morphological awareness explained unique variance in word reading and reading comprehension. In addition, we investigated the effects of orthographic and phonological opacity in morphological processing. Results indicated that adults with low literacy skills were more impaired than skilled readers on items containing phonological changes but were spared on items involving orthographic changes. These results are consistent with previous findings of adults with low literacy skills reliance on orthographic codes. Educational implications are discussed.  相似文献   

Which future,university or bureaucracy?     

Jim Binder 《Innovative Higher Education》1983,8(1):29-37

This article is critical of major institutions of higher education because they often establish criteria for rewarding professors and organizational processes that have little to do with developing a real university. The author argues for the reconstruction of universities based on values of freedom and responsibility. A model based on such values, a creative university is developed and contrasted with educational bureaucracies. Arguments are given to favor the creative university as our best hope for the future.  相似文献

Reading expressively and understanding thoroughly: An examination of prosody in adults with low literacy skills     

Katherine S. Binder  Elizabeth Tighe  Yue Jiang  Katharine Kaftanski  Cynthia Qi  Scott P. Ardoin 《Reading and writing》2013,26(5):665-680

The purpose of the current study was to explore the relationship between prosody, which is the expressive quality of reading out loud, and reading comprehension in adults with low literacy skills compared to skilled readers. All participants read a passage orally, and we extracted prosodic measures from the recordings. We examined pitch changes and how long readers paused at various points while reading. Finally, for the adults with low literacy skills, we collected information on decoding, word recognition, and reading comprehension. We found several interesting results. First, adults with low literacy skills paused longer than skilled readers and paused at a substantially greater number of punctuation marks. Second, while adults with low literacy skills do mark the end of declarative sentences with a pitch declination similar to skilled readers, their readings of questions lack a change in pitch. Third, decoding and word recognition skills were related to pauses while reading; readers with lower skills made longer and more frequent and inappropriate pauses. Finally, pausing measures explained a significant amount of variance in reading comprehension among the adults with low literacy skills.  相似文献   

Hypertext Design Issues     

Carl Binder 《Performance Improvement Quarterly》1989,2(3):16-33

Hypertext is a computer technology for “nonsequential reading and writing” in which chunks or nodes of information are connected by fixed links. Users access hypertext by selecting cross-reference (or “buttons”) in the context of a given node that is connected via links to other nodes. Such an “associative” strategy for information storage and retrieval differs from the indexing and searching technology of conventional database management and text retrieval systems, and offers significant advantages when used instead of or in combination with search systems. Hypertext is an ideal medium for making job aids, reference materials, and ‘just in time training’ available online to information-based workers. This article reviews five commercially available hypertext systems, and discusses several key hypertext design issues. Among the most important of these issues are the critical role of navigational aids in preventing users from becoming “lost” in the hypertext, the application of structured writing techniques to hypertext development, and the potential contributions of the human performance technology approach to hypertext in the form of systematic analysis, design, and evaluation methods.  相似文献   

Ein Fuzzy-Rechercheassistent für bibliographische Datenbanken     

Ingo R. Homann und Wolfgang Binder 《Informatik - Forschung und Entwicklung》2004,19(2):97-108

Zusammenfassung. Dadurch, dass Literaturnachweise und Publikationen zunehmend in elektronischer und auch vernetzter Form angeboten werden, haben Anzahl und Größe der von wissenschaftlichen Bibliotheken angebotenen Datenbanken erheblich zugenommen. In den verbreiteten Metasuchen über mehrere Datenbanken sind Suchen mit natürlichsprachlichen Suchbegriffen heute der kleinste gemeinsame Nenner. Sie führen aber wegen der bekannten Mängel des booleschen Retrievals häufig zu Treffermengen, die entweder zu speziell oder zu lang und zu unspezifisch sind. Die Technische Fakultät der Universität Bielefeld und die Universitätsbibliothek Bielefeld haben einen auf Fuzzy- Suchlogik basierenden Rechercheassistenten entwickelt, der die Suchanfragen der Benutzer in Teilsuchfragen an die externen Datenbanken zerlegt und die erhaltenen Teilsuchergebnisse in einer nach Relevanz sortierten Liste kumuliert. Es ist möglich, Suchbegriffe zu gewichten und durch Fuzzy- Aggregationsoperatoren zu verknüpfen, die auf der Benutzeroberfläche durch natürlichsprachliche Fuzzy-Quantoren wie möglichst viele, einige u.a. repräsentiert werden. Die Suchparameter werden in der intuitiv bedienbaren einfachen Suche automatisch nach heuristischen Regeln ermittelt, können in einer erweiterten Suche aber auch explizit eingestellt werden. Die Suchmöglichkeiten werden durch Suchen nach ähnlichen Dokumenten und Vorschlagslisten für weitere Suchbegriffe ergänzt. Wir beschreiben die Ausgangssituation, den theoretischen Ansatz, die Benutzeroberfläche und berichten über eine Evalution zur Benutzung und einen Vergleichstest betreffend die Effizienz der Retrievalmethodik.CR Subject Classification: H.3.3, H.3.5Eingegangen am 3.

Promoting HPT Innovations A Return to Our Natural Science Roots     

Carl Binder 《Performance Improvement Quarterly》1995,8(2):95-113

The core innovations represented by the field of Human Performance Technology (HPT) trace their origins, by way of Programmed Instruction, to the field of Behavior Analysis, a natural science methodology for the study of behavior developed by B.F. Skinner. This methodology, like all experimental natural science, rests on a foundation of functional analysis and standard units of measurement. Functional analysis is basic experimental method, whereby the investigator or practitioner keeps all but one variable constant, changes the variable in question (an “intervention”), and measures the effect on other variables. Behavior Analysis, like HPT, emphasizes prediction and control of individual behavior rather than determination of average effects across groups of individuals. In order for HPT to support and encourage greater and more effective innovation, it must re-emphasize reliance on standard units of measurement and functional analysis and promote policies and procedures that increase variation of interventions. The combination of encouraging variation and selecting interventions by means of functional analysis and objective measurement will ensure steady, reliable progress in Human Performance Technology.  相似文献
