This document reports on the results of re-designing and re-implementing the Ceilidh courseware system. It highlights the limitations identified in the thirteen years of Ceilidh's use at the University of Nottingham. It also illustrates how most of these limitations have been resolved by re-designing Ceilidh's architecture and improving various aspects of the marking and administrating processes. The new system, entitled CourseMarker, offers enhanced functionality by adding useful features that have long been needed by Ceilidh's community. The paper concludes with an evaluation of the changes and a brief report on the experience of CourseMarker's use over the last three years. Finally, recent developments and future directions are discussed.  相似文献

Retrieval practice has been shown to produce powerful learning gains in laboratory experiments but has seldom been explored in classrooms as a means of enhancing students’ learning of their course-relevant material. Furthermore, research is lacking concerning the role of individual differences in learning from retrieval. The current study explored the effects of retrieval in a large undergraduate introductory biology course as a function of individual differences in student achievement. Students completed in-class exercises that required them to retrieve course information (e.g., recalling definitions for terms and labeling diagrams) followed by feedback or to simply copy the information without retrieving it. A later quiz over the information showed that high-performing students benefited more from retrieving than copying, whereas middle- and low-performing students benefited more from copying than retrieving. When asked to predict their quiz scores following the in-class exercises, high-performers demonstrated better overall metacognitive calibration compared to middle- or low-performers. These results highlight the importance of individual differences in learning from retrieval and encourage future research using course-relevant material to consider the role of student achievement in classroom-based interventions.  相似文献

The delivery of postgraduate courses to registered nurses is faced with the challenge of providing learning opportunities which accommodate a wide range of backgrounds and which draw upon the students' clinical experiences as well as upon conventional academic sources. Courses not providing such opportunities may be devalued by the students and perceived by them as removed from, and irrelevant to, clinical practice.

This paper describes a course which appears to have been successful both in providing for background diversity and in securing the integration of academic content and the clinical experiences of postgraduate nursing students. The course uses a problem based learning approach to cover concepts and principles relating to patient education and aspects of clinical teaching. The rationale of the approach and an outline of its features are provided.

The procedures used to evaluate the course are also described. The qualitative and quantitative data realised by these procedures indicate that the course was perceived by the students to be stimulating, interesting and consonant with their clinical needs and aspirations. The data also show that the main cognitive objective of the course was achieved by a substantial proportion of the students but that students would benefit from receiving more assistance with their learning skills.

It is concluded that the form of problem based learning used in the course can provide for the postgraduate educational needs of nurses from diverse professional and academic backgrounds.  相似文献

BACKGROUND: To determine whether CT-detected cerebral infarct in young children is associated more often with abuse or unintentional head injury. METHODS: Retrospective case-control study of injured children under age 6 who had abnormal initial head CT scans and who were admitted to the only Level I pediatric trauma center in Washington State for closed head injury (CHI) from January 1, 1992 to December 31, 1998. RESULTS: Fifteen children developed cerebral infarct after CHI during the 7 year period. These cases were compared to 53 controls (those who did not develop infarct). After adjusting for the presence of SDH and for severity of injury, patients with infarcts were six times more likely to have been abused than patients without infarcts (OR 6.1; 95% CI, 1.02-36.0). CONCLUSIONS: Cerebral infarct after CHI appears to result more frequently from abuse than unintentional injury in young children.  相似文献

While research indicates that technology can be useful for supporting learning and collaboration, there is still relatively little uptake or widespread implementation of these technologies in classrooms. In this paper, we explore one aspect of the development of a multi-touch classroom, looking at two different designs of the classroom environment to explore how classroom layout may influence group interaction and learning. Three classes of students working in groups of four were taught in the traditional forward-facing room condition, while three classes worked in a centered room condition. Our results indicate that while the outcomes on tasks were similar across conditions, groups engaged in more talk (but not more off-task talk) in a centered room layout, than in a traditional forward-facing room. These results suggest that the use of technology in the classroom may be influenced by the location of the technology, both in terms of the learning outcomes and the interaction behaviors of students. The findings highlight the importance of considering the learning environment when designing technology to support learning, and ensuring that integration of technology into formal learning environments is done with attention to how the technology may disrupt, or contribute to, the classroom interaction practices.  相似文献

Differentiated thyroid carcinoma (DTC) generally has a favorable outcome. Thyroid disease, treatments, stress, and comorbidity can compromise health-related quality of life (QoL) and indirectly weigh upon the outcome. From 2004 to 2008, we evaluated QoL longitudinally in 128 DTC subjects. During scheduled examinations, subjects were asked to undergo a semi-structured psychiatric interview and five rated inventories. The same examination was conducted in 219 subjects after surgery for benign thyroid pathology. Low scores represent a better QoL. DTC and control subjects were similar in terms of age, male/female ratio, concomitant psychopharmacological treatments, and frequency of psychiatric diseases. In DTC subjects, Billewicz scale (BS) scores showed an increasing trend over time, especially among females. The ad hoc thyroid questionnaire (TQ) scores were similar in both groups and did not change over time, but at the end of the study ad hoc TQ and BS were significantly related. Ad hoc TQ scores were also related to age on entry to the study. In both male and female DTC subjects, Hamilton’s tests for anxiety (HAM-A), but not for depression (HAM-D), showed an improving trend. At the end of the study, HAM-A and HAM-D scores were comparable to those of the control group. HAM-A and HAM-D were both positively correlated with the stage of cancer and the time between diagnosis and treatment. Only HAM-D correlated with age on entry to the study. Kellner symptom questionnaire (KSQ) item scores were higher in DTC subjects than in controls. The change over time in the items including anxiety, somatization, depression, and hostility was significant. Somatization and hostility were more significantly reduced in DTC females than in DTC males. Hostility scores were significantly lower in DTC subjects than in controls at the end of the study. Somatization and depression were significantly related to staging on diagnosis and age on entry to the study. Our study confirms a wide variation of illness perception in DTC subjects, which is generally unrelated to the favorable clinical follow-up of the disease. Psychological evaluation during long-term follow-up improved QoL scores, which reached the same levels noted in subjects with a history of thyroid surgery for benign thyroid pathology. Our data indicate that special attention should be paid to QoL in older DTC subjects and those with more severe staging on diagnosis.  相似文献

Eating disorders often emerge, resurface, or worsen in individuals during college (National Eating Disorders Association, 2013), substantiating the need to identify protective factors. The relationship between mindfulness, self‐compassion, and emotion regulation and disordered eating was examined in a sample of 100 university students. Results of a path analysis indicated significant direct and indirect effects. Clinical implications and recommendations for future research are discussed.  相似文献

Children may say they want to grow up to be a police officer, but we typically do not hear children saying they want to work in a prison or jail when they grow up. Given negative media attention of correctional facilities, it may not be surprising that many students enter criminal justice programs uninterested in correctional careers. Correctional facility tours can be useful for exposing criminal justice students to careers they may not have previously considered or ones about which they held negative stereotypes. Drawing on the premises of Experiential Learning Theory and using student essays, we address the following research questions: (1) Does attending a jail or prison tour influence how students think of correctional officers and correctional careers? (2) What perceptions do students have of correctional officers prior to attending a jail or prison tour and what do students think of correctional officers after the tour?  相似文献

ABSTRACT

Case studies have been a central methodology employed by scholars working in the rhetoric of science and technical communication. However, concerns have been raised about how cases are constructed and collected, and what they convey. The authors reflect on how rhetoricians of science and technical communication researchers can – and do – construct a variety of case-based mixed-methods studies in ways that may make our research more portable and durable without undercutting the important and central role of case-based analysis.  相似文献
