Effects of knowledge and display design on comprehension of complex graphics     

Matt Canham  Mary Hegarty 《Learning and Instruction》2010,20(2):155-166

In two experiments, participants made inferences from weather maps, before and after they received instruction about relevant meteorological principles. Different versions of the maps showed either task-relevant information alone, or both task-relevant and task-irrelevant information. Participants improved on the inference task after instruction, indicating that they could apply newly acquired declarative knowledge to make inferences from graphics. In Experiment 1, participants spent more time viewing task-relevant information and less time viewing task-irrelevant information after instruction, and in Experiment 2, the presence of task-irrelevant information impaired performance. These results show that domain knowledge can affect information selection and encoding from complex graphics as well as processes of interpreting and making inferences from the encoded information. They also provide validation of one principle for the design of effective graphical displays, namely that graphics should not display more information than is required for the task at hand.  相似文献

The textbook problem: Investigating one possible solution     

Mary S. Laskowski   《Library Collections, Acquisitions, and Technical Services》2007,31(3-4):161-170

This article explores the inherent problems for academic libraries in providing access to textbooks to students, the growing demand for such access by students, and presents the findings of a reserve pilot project conducted at a major Midwest university. Findings indicate the pros and cons of the pilot attempted as well as demonstrating the need for continued research and collaborative work with appropriate organizations on the campus and beyond.  相似文献

Perceptions of nurses and mothers in four studies of the peripartum period          下载免费PDF全文

Moore ML 《The Journal of perinatal education》2004,13(3):55-57

How individuals perceive themselves and how they are perceived by others are an important part of the relationships between childbirth educators, nurses, other health-care providers, and the families they serve. In this paper, four studies are reviewed. One study focused on labor nurses' perception of their roles. Three other studies, each using a different research strategy, examined mothers' perceptions of their experiences during the peripartum period.  相似文献   

Library service delivery via hand-held computers--the right information at the point of care     

Peterson M 《Health information and libraries journal》2004,21(1):52-56

Today's health and medical librarians are well aware of the move towards evidence-based clinical practice which has emerged during the past decade. Hand-in-hand with this trend is the need for health practitioners to have access to the best possible evidence to help them in their clinical decision making. Libraries have a key role in the provision of information to their clients, and this means keeping abreast, not only of the various information sources available, but also the means by which those sources may be used. This paper will examine the effects that the hand-held computer is having on the work practices of our clients-library users. It is hoped that the paper will give an insight into the various types of library material which are suitable for use with hand-held devices, and an understanding of their advantages and limitations.  相似文献   

Individual pathways in the development of forceful throwing     

Langendorfer SJ  Roberton MA 《Research quarterly for exercise and sport》2002,73(3):245-256

Halverson, Roberton, and Langendorfer (1982) reported the development of children ages 6-13 years filmed longitudinally performing the forceful overarm throw. These authors described the children's progress through developmental sequences for trunk, humerus, and forearm actions; however, they did not study developmental relationships ("profiles") across these components. This paper reports how the profiles changed in the same children across trials within filming sessions and over time. The data revealed both common and individual developmental pathways. The frequencies of some pathways were not chance occurrences (p < or = .01), suggesting that within-person constraints eliminated certain movement relationships while encouraging others. The authors hypothesize that the kinematics of trunk rotation may serve as a control parameter for pattern change.  相似文献

Validating Student Score Inferences With Person‐Fit Statistic and Verbal Reports: A Person‐Fit Study for Cognitive Diagnostic Assessment     

Ying Cui  Mary Roduta Roberts 《Educational Measurement》2013,32(1):34-42

The goal of this study was to investigate the usefulness of person‐fit analysis in validating student score inferences in a cognitive diagnostic assessment. In this study, a two‐stage procedure was used to evaluate person fit for a diagnostic test in the domain of statistical hypothesis testing. In the first stage, the person‐fit statistic, the hierarchy consistency index (HCI; Cui, 2007 ; Cui & Leighton, 2009 ), was used to identify the misfitting student item‐score vectors. In the second stage, students’ verbal reports were collected to provide additional information about students’ response processes so as to reveal the actual causes of misfits. This two‐stage procedure helped to identify the misfits of item‐score vectors to the cognitive model used in the design and analysis of the diagnostic test, and to discover the reasons of misfits so that students’ problem‐solving strategies were better understood and their performances were interpreted in a more meaningful way.  相似文献
