Previous studies have shown that anatomy students who complete oral laboratory presentations believe they understand the material better and retain it longer than they otherwise would if they only took examinations on the material; however, we have found no studies that empirically test such outcomes. The purpose of this study was to assess the effectiveness of oral presentations through comparisons with other methods of assessment, most notably, examination performance. Specifically, we tested whether students (n = 256) performed better on examination questions on topics covered by their oral presentations than on other topics. Each student completed two graded, 12‐minute laboratory presentations on two different assigned topics during the course and took three examinations, each of which covered a third of the course material. Examination questions were characterized by type (memorization, pathway, analytical, spatial). A two‐way repeated measures analysis of variance revealed that students performed better on topics covered by their presentations than on topics not covered by their presentations (P < 0.005), regardless of presentation grade (P > 0.05) and question type (P > 0.05). These results demonstrate empirically that oral presentations are an effective learning tool. Anat Sci Educ 2: 260–264, 2009. © 2009 American Association of Anatomists. 相似文献

The purpose of this qualitative study is to explore the reasons university students with nonapparent disabilities gave for formally disclosing their disability and seeking the university’s disability services or not and the consequences they associate with their decisions. Conducted in a Mid-western four-year university, nine students with self-identified nonapparent disabilities participated in the study. Qualitative semistructured interviews were conducted to gather in-depth data from participants. A five-stage approach to qualitative data analysis was adapted to analyse the data. The findings indicate positive experiences with formal disability disclosure, but revealed barriers impeding students’ desire to disclose. Recommendations challenge colleges and universities to create an inclusive ethos for all students with disabilities by removing barriers impeding their full participation in academia. 相似文献

IntroductionThe Fourth Universal Definition of Myocardial Infarction Global Taskforce recommends the use of high sensitive troponin (hs-Tn) assays in the diagnosis of acute myocardial infarction. We evaluated the analytical performance of the Atellica IM High-sensitivity Troponin I Assay (hs-TnI) (Siemens Healthcare Diagnostics Inc., Tarrytown, USA) and compared its performance to other hs-TnI assays (Siemens Advia Centaur, Dimension Vista, Dimension EXL, and Abbott Architect (Wiesbaden, Germany)) at one or more sites across Europe.Materials and methodsPrecision, detection limit, linearity, method comparison, and interference studies were performed according to Clinical and Laboratory Standards Institute protocols. Values in 40 healthy individuals were compared to the manufacturer’s cut-offs. Sample turnaround time (TAT) was examined.ResultsImprecision repeatability CVs were 1.1–4.7% and within-lab imprecision were 1.8–7.6% (10.0–25,000 ng/L). The limit of blank (LoB), detection (LoD), and quantitation (LoQ) aligned with the manufacturer’s values of 0.5 ng/L, 1.6 ng/L, and 2.5 ng/L, respectively. Passing-Bablok regression demonstrated good correlations between Atellica IM analyser with other systems; some minor deviations were observed. All results in healthy volunteers fell below the 99th percentile URL, and greater than 50% of each sex demonstrated values above the LoD. No interference was observed for biotin (≤ 1500 µg/L), but a slight bias at 5.0 g/L haemoglobin and 50 ng/L Tn was observed. TAT from was fast (mean time = 10.9 minutes) and reproducible (6%CV).ConclusionsReal-world analytical and TAT performance of the hs-TnI assay on the Atellica IM analyser make this assay fit for routine use in clinical laboratories. 相似文献

This article investigates the discursive register through which lives become grievable by focusing on a case study of the discourses surrounding the death of radical feminist, Andrea Dworkin. I argue that Dworkin becomes embroiled in an interlocking nexus of illicit subject positions that set the terms of her grievability and obstruct recognition of her as a rational being by framing her (1) as the quintessential emotional and irrational woman who is not worthy of the respect typically offered to the dead and (2) in relation to her wild, unruly, and excessive body, which is conflated with her feral work. 相似文献

In 1981, President Reagan declared a moratorium on the production of new government-financed pamphlets, periodicals, and audiovisuals. This study examines the impact of that action on the format and content of printed publications, issued during the freeze, by the Department of Health and Human Services. Analysis of those publications distributed to Government Printing Office depository libraries during the moratorium reflected: (1) no significant reduction in the number of documents produced, (2) a shift toward smaller, less-costly print formats, and (3) no significant reduction in the release of publicity/advertising materials. Changes observed in the quantity, format, and content of Department of Health and Human Services publications issued during the moratorium were not those expected given the presidential guidelines. 相似文献

Teaching with student response systems in elementary and secondary education settings: A survey study 总被引:2,自引:0,他引:2

This study examined how 498 elementary and secondary educators use student response systems in their instruction. The teachers
all completed an online questionnaire designed to learn about their goals for using response systems, the instructional strategies
they employ when using the system, and the perceived effects of response systems. Participants in the study tended to use
similar instructional strategies when using the technology as have been reported in higher education. These include posing
questions to check for student understanding and diagnose student difficulties, sharing a display of student responses for
all to see, asking students to discuss or rethink answers, and using feedback from responses to adjust instruction. A latent
class analysis of the data yielded four profiles of teacher use based on frequency of use and breadth of instructional strategies
employed. Teachers who used the technology most frequently and who employed broadest array of strategies were more likely
to have received professional development in instructional strategies and to perceive the technology as more effective with
students. 相似文献

Sociocultural theories of learning and development underpin a number of studies of young children's experiences as they move from early childhood education centres to school settings. This paper summarises research designed to investigate children's transition to primary school from Pacific early childhood centres in New Zealand. The study records experiences of transition to school of families from each of five Pacific groups (Cook Islands, Niue, Samoa, Tokelau, and Tonga). The emphasis is on language and children's other experiences as they move from Pacific Islands early childhood centres into English-language primary schools. Findings from in-depth interviews with children, parents, early childhood teachers, and school teachers are summarised, and brief reference is also made to analyses of the content of the 19 participating schools' charters. The paper draws on sociocultural perspectives to comment on aspects of facilitating transition. Les the´ories socioculturelles d'apprentissage et de de´veloppement soutiennent un certain nombre d'e´tudes sur les expe´riences des petits enfants pendant qu'ils se de´placent des centres d'e´ducation de la petite enfance a ¤ un cadre d'e´cole. Cet article re´sume la recherche conc¸ue pour e´tudier la transition des enfants a ¤ l'e´cole primaire des centres d'e´ducation de la petite enfance d'iles Pacifiques en Nouvelle-Ze´lande. Cette e´tude enregistre des expe´riences de transition a ¤ l'e´cole des familles de chacun de cinq groupes Pacifiques (iles Cook, Nioue´, Samoa, Toke´lao, et Tonga). L'emphase est sur la langue et les autres expe´riences des enfants pendant qu'ils se de´placent des centres d'e´ducation de la petite enfance d'iles Pacifiques dans les e´coles primaires de langue anglaise. Des re´sultats des entrevues de´taille´es avec des enfants, avec des parents, avec des enseignants spe´cialise´s dans l'e´tude la petite enfance, et des enseignants d'e´cole sont re´sume´s, et on fait une re´fe´rence bre ¤ ve aux analyses du contenu des chartes des 19 e´coles qui participent. L'article tire sur des perspectives socioculturelles pour faire des observations sur des aspects de la facilitation de la transition. Las teori´as socio-culturales del aprendizaje y el desarrollo apuntalan un nu´mero de estudios sobre las experiencias de nin ¨ os pequen ¨ os cuando pasan de los centros de educacio´n para la primera infancia al medio de la escuela. Este ensayo resume la investigacio ´n disen ¨ ada para investigar la transicio´n de los nin ¨ os a la escuela primaria de centros preescolares del Paci´fico en Nueva Zelanda. El estudio registra experiencias de la transicio´n a la escuela de familias de cada uno de cinco grupos del Paci´fico (islas Cook, Niue, Samoa, Tokelau, y Tonga). El e´nfasis esta´ en el lenguaje y las otras experiencias por las que pasan los nin ¨ os al desplazarse de los centros pre-escolares de las Islas del Paci´fico a las escuelas primarias de lengua inglesa. Se resumen aqui´ los resultados de entrevistas detalladas con los nin ¨ os, los padres, los maestros de la primera infancia, los ensen ¨ antes de escuela y se hace breve referencia a los ana´lisis del contenido de los estatutos de las 19 escuelas que participan. El ensayo utiliza las perspectivas socioculturales para comentar sobre los aspectos de la facilitacio´n de esta transicio´n. 相似文献
