The coronavirus disease 2019 (Covid-19) pandemic caused an abrupt transition from face-to-face to online anatomy teaching, learning, and assessment. Although online education has ensured the continuity of anatomy education during the pandemic, its implementation has been challenging, and its effectiveness has been questioned. Therefore, literature pertinent to online anatomy education during the pandemic is crucial to explain Covid-19's disruptions to this field. Accordingly, this scoping review explored changes, disruptions, and gaps in anatomy teaching and assessment during Covid-19 using an enhanced version of Arksey and O′Malley's six-stage protocol. Five online databases were searched for articles that described changes and disruptions in anatomy education. Three independent researchers were involved in titles, abstracts, and full texts screening, while another four researchers were independently involved in data extraction, charting, and synthesis. This review revealed six themes: immediate strategic plans and actions, teaching and learning changes, online assessment practice, students' and educators' receptivity and adaptability, online learning and assessment effects, and future directions. It also revealed four gaps: non-future-ready curricula, learning obstacles, administrative and teaching challenges, and online education ethical issues. The results were reported in tabular and narrative forms, following the PRISMA Extension for Scoping Reviews (PRISMA-ScR guidelines). Understanding the evolution and gaps in anatomy education during the Covid-19 pandemic will help anatomists design future-ready, adaptable curricula.  相似文献   

Training Transfer and Transfer Motivation: The Influence of Individual,Environmental, Situational,Training Design,and Affective Reaction Factors     

Muhammad Awais Bhatti  Sharrifah Ali  Mohd Faizal Mohd Isa  Mohamed Mohamed Battour 《Performance Improvement Quarterly》2014,27(1):51-82

The purpose of this study is to examine the effects of individual, environmental, training design, and affective reaction factors on training transfer and transfer motivation. To determine the relationship between these factors and their influence on training transfer and to test the model, the researchers collected data from employees in the Malaysian banking sector. Structural equation modeling with Amos 16 was used to test the model and determine the relationship. The study suggested that training stakeholders should manage the training program effectively. Transfer is maximized when trainees have social support, high performance self‐efficacy, and transfer motivation. Stakeholders (e.g., trainers, trainees, supervisors, and peers) are important to the training transfer process, as are learner readiness, trainee reaction, instrumentality, and training retention. This study revealed that perceived content validity and transfer design work together and influence the trainee's performance self‐efficacy. In other words, if trainers want to improve the performance self‐efficacy level of trainees, they need to explain how the trainee can transfer the learned skills at the workplace and make sure the content of the training is similar to the actual job. The main objective of training programs is to align the employee's expertise with organizational goals. Organizations can achieve their desired objectives only when employees transfer the learned skills on the job. Unfortunately, employees often transfer only a small percentage of skills they have learned in training. To effectively manage their training programs, organizations need to identify and focus on the factors that resist effective training transfer.  相似文献   

Mathematics Achievement as a Function of Within- and Between-School Differences     

Ebrahim Mohammadpour  Mohamed Najib Abdul Ghafar 《Scandinavian Journal of Educational Research》2014,58(2):189-221

Achievement in mathematics of eighth-grade students is modeled as a function of within-school, between-school and cross-country differences. The data were obtained from 217,728 students, within 7,216 secondary schools, in 48 countries, who participated in the 2007 Trends in International Mathematics and Science Study. Multilevel analysis showed that out of the total variance in mathematics achievement, 40.39%, 20.61%, and 38.99% were accounted for within-school, between-school-within-country, and cross-country differences, respectively. Mathematics self-concept followed by socioeconomic status was the strongest predictor of achievement at the student level. At the school level, school location yielded the strongest link to achievement, while at the country level socioeconomic status was the main predictor of national mathematics average.  相似文献

Alleviation of Dimethylnitrosamine-Induced Liver Injury and Fibrosis by Supplementation of Anabasis articulata Extract in Rats     

Azza M. Mohamed  Mohga S. Abdalla  Maha Z. Rizk  El-Sayed M. E. Mahdy  Abdel-Razik H. Farrag  Fatma S. El-Sharabasy  Hanan F. Aly  Mohamed R. Mohamed 《Indian journal of clinical biochemistry : IJCB》2014,29(4):418-429

Anabasis articulata (Forssk) Moq. (Chenopodiaceae) is an herb, grows in Egypt, and used in folk medicine to treat diabetes, fever, and kidney infections. The protective and therapeutic effects of the ethanol extract of A. articulata aerial parts were evaluated against dimethylnitrosamine (DMN)-induced liver fibrosis, compared with the standard drug, silymarin. Hepatic hydroxyproline content, serum transforming growth factor-β1 (TGF-β1), interleukin 10 (IL-10) and fructosamine were measured as liver fibrosis markers. Hepatic malondialdehyde (MDA), nitric oxide (NO), catalase (CAT), glutathione reductase (GR) and glutathione content (GSH) were measured as oxidant/antioxidant markers. Parallel histopathological investigations were also performed. Protective and therapeutic administration of A. articulata (100 mg/kg daily for 4 weeks), markedly prevented DMN-induced loss in body and liver weights. The extract significantly inhibited the elevation of hepatic hydroxyproline, NO and MDA (P < 0.05), as well as serum fructosamine, and TGF-β1 (P < 0.05) induced by DMN while it restored IL-10 to normal level in both protective and therapeutic groups. Furthermore, A. articulata prevented the depletion in CAT, GR, and GSH levels (P ≤ 0.05). In addition, oral administration of A. articulata extract and silymarin to both protective and therapeutic groups reduced the increase in liver function enzyme activities; alanine and aspartate amintransferases, gamma-glutamyl transferase in addition to alkaline phosphatase, and caused significant increase in serum albumin concentration as compared to DMN group. These data corresponded closely with those obtained for the drug silymarin. Histopathological studies confirmed the biochemical data and revealed remarkable improvement in liver architecture. Thus, it could be concluded that, A. articulata extract exhibited in vivo hepatoprotective and therapeutic effects against DMN-induced liver injury and may act as a useful agent in controlling the progression of hepatic fibrosis through reduction of oxidative stress and improving liver function.  相似文献   

Predicting e-readiness at firm-level: An analysis of technological,organizational and environmental (TOE) effects on e-maintenance readiness in manufacturing firms     

Mohamed Gamal Aboelmaged 《International Journal of Information Management》2014

This study predicts the impact of technological, organizational and environmental (TOE) determinants on e-maintenance technology readiness in manufacturing firms. Survey responses of 308 managers from a wide spectrum of manufacturing firms have been validated and analyzed by means of structural equation modelling. The findings indicate that dimensions of e-maintenance technology readiness in manufacturing firms are mainly influenced by technological and organizational determinants involving technological infrastructure and competence, expected benefits and challenges of e-maintenance, and firm size and ownership. Surprisingly, there is no significant effect of competitive pressures on e-maintenance readiness. This study offers managers and vendors a frame of reference to analyze firm's situation before initiating new innovations. In case of e-maintenance technology, adoption strategies should be built around fostering level of employees’ technological knowledge and skills, technology infrastructure as well as sustaining potential benefits and encountering potential challenges associated with e-maintenance technology. This paper is one of the early studies that predict dimensions of technology readiness index (TRI) through the determinants of technology–organization–environment (TOE) framework. Also, it is among the first attempts to link prominent technology adoption models to e-maintenance technology as a novel form of enterprise innovations.  相似文献   

Tour de France,Giro, Vuelta,and classic European races show a unique progression of road cycling speed in the last 20 years

Abstract

Road cycling ranks among the most intense endurance exercises. Previous studies and mathematical models describing road cycling have not analysed performances per se. We describe the evolution of road cycling performance over the past 116 years. We studied the top ten cyclists' mean speeds in eight famous classic races and three European Grand Tours, using a previously published multi-exponential model that highlights the different progression periods of an event during the century. In addition, we measured an indicator of difficulty for the Tour de France by calculating the climbing index (i.e. the total altitude climbed over total distance). The eleven races' mean speed increased progressively from 23.13 km · h^?1 in 1892 to 41.19 ± 2.03 km · h^?1 in 2008. Road cycling development, like other quantifiable disciplines, fits a piecewise progression pattern that follows three periods: before, between, and after the two World Wars. However, a fourth period begins after 1993, providing a speed progression of 6.38% from the third one. The Tour de France's climbing index also provided insight into a recent paradoxical relationship with speeds: when the climbing index increased, the winner's speed also increased. Our results show a major improvement (6.38%) in road cycling performance in the last 20 years and question the role of extra-physiological parameters in this recent progression.  相似文献   

Teaching elements of nature of science: A yearlong case study of a fourth‐grade teacher     

Valarie L. Akerson  Fouad Abd‐El‐Khalick 《科学教学研究杂志》2003,40(10):1025-1049

This study examined and supported the efforts of Tina, an experienced elementary teacher, in helping her fourth graders internalize informed views of the inferential, tentative, and creative nature of science (NOS). Tina held informed views of, and was motivated to teach about, NOS. The study aimed to answer the following question: What specific supports were needed to enable Tina to make the target NOS elements explicit in her teaching? The lead researcher visited Tina's classroom every week and interacted with her on a continuous basis. Data sources included classroom observations and videotapes, teacher NOS questionnaires and associated interviews, teacher–researcher communications, and teacher and researcher logs. Although Tina's understandings and intentions were necessary to enable her to teach about NOS, they were not sufficient. Tina needed support to translate her NOS views and intentions into pedagogically appropriate instructional activities that would make the target NOS aspects accessible to her students. Socially mediated support was needed at the personal level in terms of helping Tina activate her tacit NOS understandings, and at the professional level in terms of modeling explicit NOS instruction in Tina's own classroom by the lead researcher. © 2003 Wiley Periodicals, Inc.
