Young children working together. Cooperative learning effects on group work of children in Grade 1 of primary education     

《Learning and Instruction》2020

It was examined whether cooperative learning within the Success for All (SfA) program led to improved group work behaviour of Grade 1 pupils. 168 pupils of six SfA schools and 144 pupils of four control schools participated. Positive and negative group work behaviour was observed during a group task, taking into account socioemotional ethos, group participation, and type of dialogue. Longitudinal multilevel analysis was used for the sequence of observed 20-s time intervals. SfA groups showed more positive and less negative group work behaviour compared to control groups, whilst controlling for several group characteristics. Results suggest that negative group work behaviour increased gradually during the whole task in control groups, while in SfA groups it increased only towards the end of the task. The findings indicate that cooperative learning may lead to improved group work behaviour of young pupils (6–7 years old).  相似文献   

Covid-19: Emerging Considerations for Body Sourcing and Handling. A Perspective View from Nigeria     

Izuchukwu Azuka Okafor  Terkuma Chia 《Anatomical sciences education》2021,14(2):154-162

The current Coronavirus disease (Covid-19) pandemic has spread to about 220 countries of the world and has resulted in a significant number of deaths globally. Infections are still on the rise, and the impact on the global death rate could be devastating. There are fears over the likely impact of a large number of deaths on body sourcing and handling of cadavers for teaching and research. Historically, epidemics come with several challenges and have often led to some level of negligence of ethical practices and health and safety regulations associated with body sourcing and handling. The authors highlighted some emerging problems in this article, focusing on Africa and Nigeria in particular. These problems include a higher risk of coronavirus exposure for body handlers, shortage of cadavers for teaching and learning, a lack of standard regulations leading to unethical body sourcing and handling, and a lack of monitoring and collaboration needed for a well-coordinated Covid-19 pandemic response strategy. If these issues are ignored, the previous gains made in anatomical ethical practices may be destroyed. Some useful recommendations for policymaking geared toward prevention or curtailing these emerging issues have been instilled in this article.  相似文献   

The Unintentional Effects on Body Donation Programs of a Competency-Based Curriculum in Postgraduate Medical Education     

Geoffroy P.J.C. Noël  Joseph Dubé  Gabriel Venne 《Anatomical sciences education》2021,14(5):675-681

As medical programs place increasing importance on competency-based training and surgical simulations for residents, anatomy laboratories, and body donation programs find themselves in a position of adapting to changing demands. To better assess the demand for “life-like” cadaveric specimens and evaluate the possible impacts that competency-based medical education could have upon the body donation program of McGill University, Canada, the authors tracked, over the course of the last 10 years, the number of soft-embalmed specimens, along with the number of teaching sessions and the residents enrolled in competency-based programs that are using cadaveric material. The results reveal that the number of soft-embalmed specimens used within residency training increased from 5 in 2009 to 35 in 2019, representing an increase from 6% of bodies to 36.5% of the total number of body donors embalmed in this institution. Correspondingly, the number of annual teaching sessions for residents increased from 19 in 2012 to 116 in 2019. These increases in teaching are correlated with increasing number of residents enrolled in competency-based programs over the last 3 years (Pearson r ranging from 0.9705 to 0.9903, and R² ranging from 0.9418 to 0.9808). Those results suggest that the new skill-centered curricula which require residents to perform specific tasks within realistic settings, exhibit a growing demand for “life-like” cadaveric specimens. Institutions’ body donation programs must, therefore, adapt to those greater need for cadaveric specimens, which presents many challenges, ranging from the logistical to the ethical.  相似文献   

Comparison of Haptic and Biometric Properties,Bacterial Load,and Student Perception of Fixative Solutions: Formaldehyde Versus Chilean Conservative Fixative Solution with and without Formaldehyde in Pig Kidneys     

Marianne Skopnik-Chicago  Katherine Poblete-Cordero  Natali Zamora  Roberto Bastías  Pablo A. Lizana 《Anatomical sciences education》2021,14(6):836-846

One of the most widely used solutions to fix and preserve organic tissues is formaldehyde, despite reservations regarding its toxicity and the fact that formaldehyde-embalmed bodies lose their original characteristics. Anatomy laboratories have been replacing formaldehyde with solutions that retain the characteristics of fresh tissue. For this purpose, alternative solutions with a very low concentration of formaldehyde or without any formaldehyde have been analyzed. The objective of this study was to compare biometry, coloration, haptic properties, and bacterial load on animal specimens (pig kidneys) embalmed with formaldehyde, and with Chilean Conservative Fixative Solution with and without formaldehyde (formaldehyde chCFS and formaldehyde-free chCFS). Also, the perception of health and biological science students toward specimens treated with different solutions was assessed. The results indicated that there were no significant differences in specimens’ retraction, or bacterial load. Students showed a preference for organs embalmed in formaldehyde chCFS and formaldehyde-free chCFS; indicating that with these treatments they could better visualize structures and that the prosections had greater flexibility and the colors were more similar to those of fresh tissue. Additionally, students recommended the material embalmed in formaldehyde chCFS and formaldehyde-free chCFS for anatomy learning. In contrast, students indicated that formaldehyde-fixation negatively affected their practical experience. In conclusion, embalming with formaldehyde chCFS or formaldehyde-free chCFS provides an advantageous practical experience over the use of formaldehyde and may be an alternative to replace the use of formaldehyde in anatomy laboratories.  相似文献   

Facilitating flexible learning by replacing classroom time with an online learning environment: A systematic review of blended learning in higher education     

《Educational Research Review》2021

Higher education institutions are trying to provide more flexibility and individualization, which is mainly realized through the use of new technologies and implemented in online or blended learning designs. This systematic review aims to investigate the impact of replacing classroom time with an online learning environment. The meta-analysis (k = 21 effect sizes) applied strict inclusion criteria concerning research design, measurement of learning outcomes and implementation of blended learning. The estimated effect size (Hedge's g) was positive, although not significantly different from zero and the confidence interval [-0.13, 0.25], suggesting that overall differences between blended and conventional classroom learning are small, and, at best, very small negative or moderate positive effects are plausible. This means that despite a reduction in classroom time between 30 and 79 per cent, equivalent learning outcomes were found. Consequently, blended learning with reduced classroom time is not systematically more or less effective than conventional classroom learning.  相似文献   

The Effectiveness of an Augmented Reality Head-Mounted Display in Learning Skull Anatomy at a Community College     

Elizabeth A. Duncan-Vaidya  Erica L. Stevenson 《Anatomical sciences education》2021,14(2):221-231

Despite an increase in the use of technology in undergraduate anatomy education, and the rising popularity of online anatomy courses at community colleges in the United States, there have been no reports on the efficacy of augmented reality on anatomy education in this population. The purpose of this study was to test the hypothesis that augmented reality is an effective and engaging tool for learning anatomy in community college students. Participants recruited from Cuyahoga Community College (Cleveland, OH) studied skull anatomy using either traditional tools (i.e., textbook and plastic skull model) or an augmented reality head-mounted display with an interactive virtual skull application. Comparison of knowledge before and following the study period revealed that augmented reality was an effective tool for learning skull anatomy: pre-quiz = 32.7% (± 25.2); mean (± SD), post-quiz = 61.8% (± 19.5); n = 15; t₍₂₈₎ = 3.53; P = 0.001. The traditional tools were equally effective: pre-quiz = 44.9 % (± 18.6), post-quiz = 67.9 % (± 17.3); n = 17; t₍₃₂₎ = 3.73; P = 0.0007. Students rated the augmented reality device as 9.6 (± 1.0); mean (± SD) when asked if it fit the statement “fun to use” on a semantic differential scale from 1 (poor) to 10 (excellent). In conclusion, this study found that augmented reality is an effective and engaging tool for the instruction of skull anatomy at a community college.  相似文献

Promoting quality education in Chile: the politics of reforming teacher careers     

Alejandra Mizala 《教育政策杂志》2020,35(4):529-555

ABSTRACT

Reformers in developing countries increasingly seek to raise education quality. Yet we know little about the politics of improving education. One significant and instructive case of reforms designed to boost education quality comes from Chile, where in 2016 the government enacted a sweeping reform of teaching careers. This paper first uses a quantitative analysis of appearances in the news to identify key stakeholders and then turns to process tracing to analyze how and when these stakeholders influenced reform dynamics. Comparatively, the Chilean case differs from similar reforms elsewhere in Latin America due to the absence of business, the strong role of policy networks, and the final negotiated settlement with the teacher union. Theoretically, the analysis confirms general theories that emphasize the roles of distributive politics and policy networks.  相似文献
