It has been noted by staff at the Faculty of Health Sciences, Stellenbosch University that medical students neglect the study of surface anatomy during dissection. This study reports on the novel use of Lodox® Statscan® images in anatomical education, particularly the teaching of surface anatomy. Full body digital X‐ray images (Lodox Statscan) of each cadaver (n = 40) were provided to second year medical students. During dissection students were asked to visualize landmarks, organs, and structures on the digital X‐ray and their cadaver, as well as palpate these landmarks and structures on themselves, their colleagues, and the cadaver. To stimulate student engagement with surface anatomy, dissection groups were required to draw both the normal and actual position of organs on a laminated image provided. The accuracy of the drawings was subsequently assessed and students were further assessed by means of practical identification tests. In addition, students were asked to complete an anonymous questionnaire. A response rate of 79% was obtained for the student questionnaire. From the questionnaire it was gathered that students found the digital X‐ray images beneficial for viewing most systems' organs, except for the pelvic organs. Although it appears that students still struggle with the study of surface anatomy, most students believed that the digital X‐rays were beneficial to their studies and supported their continued use in the future.

In this study the relationship between domain-specific skills and peer assessment skills as a function of task complexity is investigated. We hypothesised that peer assessment skills were superposed on domain-specific skills and will therefore suffer more when higher cognitive load is induced by increased task complexity. In a mixed factorial design with the between-subjects factor task complexity (simple, n?=?51; complex, n?=?59) and within-subjects factor task type (domain-specific, peer assessment), secondary school students studied four integrated study tasks, requiring them to learn a domain-specific skill (i.e. identifying the six steps of scientific research) and to learn how to assess a fictitious peer performing the same skill. Additionally, the students performed two domain-specific test tasks and two peer assessment test tasks. The interaction effect found on test performance supports our hypothesis. Implications for the teaching and learning of peer assessment skills are discussed. 相似文献

Cultural elements such as language, beliefs about health, and family context play important roles in the uptake of rehabilitation and treatment of deafness. Because of cultural issues, minority groups often do not receive optimal care. Focusing on the Netherlands, the researchers explored how the rehabilitation and counseling of deaf children of Turkish-origin parents can be improved. The most important findings were that (a) most parents initially did not believe their child was deaf and regretted later that they did not start hearing rehabilitation earlier; (b) parents had little confidence in the Dutch health care system and sought a second opinion from a medical doctor of their own national origin; (c) parents did not know how to be actively involved in the care of their deaf child. Implications for practice aimed at improving rehabilitation and counseling for these children are described. 相似文献

As the consumption of fructose and saturated fatty acids (FAs) has greatly increased in western diets and is linked with an increased risk of metabolic syndrome, the aim of this study was to investigate the effects of a moderate (10 weeks) and a prolonged (30 weeks) high fructose and saturated fatty acid (HFS) diet on plasma FA composition in rats. The effects of a few weeks of HFS diet had already been described, but in this paper we tried to establish whether these effects persist or if they are modified after 10 or 30 weeks. We hypothesized that the plasma FA profile would be altered between 10 and 30 weeks of the HFS diet. Rats fed with either the HFS or a standard diet were tested after 10 weeks and again after 30 weeks. After 10 weeks of feeding, HFS-fed rats developed the metabolic syndrome, as manifested by an increase in fasting insulinemia, total cholesterol and triglyceride levels, as well as by impaired glucose tolerance. Furthermore, the plasma FA profile of the HFS group showed higher proportions of monounsaturated FAs like palmitoleic acid [16:1(n-7)] and oleic acid [18:1(n-9)], whereas the proportions of some polyunsaturated n-6 FAs, such as linoleic acid [18:2(n-6)] and arachidonic acid [20:4(n-6)], were lower than those in the control group. After 30 weeks of the HFS diet, we observed changes mainly in the levels of 16:1(n-7) (decreased) and 20:4(n-6) (increased). Together, our results suggest that an HFS diet could lead to an adaptive response of the plasma FA profile over time, in association with the development of the metabolic syndrome. 相似文献

This study, based on the qualitatively rendered experiences and perceptions of educational leaders from historically underserved backgrounds in the US, argues that identity impacts leadership practice. To make this point, researchers build upon an emergent theoretical framework for applied critical leadership from the theories and traditions of transformational leadership, personal leadership, critical pedagogy, and critical race theory. With regard to methodology, a two-subject case study was validated by adding three additional participants for points of verification to the findings and discussion. Interview, field notes, and relevant documents were analyzed using phenomenology and constant comparative methods. Major findings indicate participants’ practice reveal characteristics of cross-cultural applied, critical, and transformational leadership. These scholarly findings are significant because they can inform mainstream leadership practices contributing to educational equity, authentic multiculturalism, improved intercultural relations, innovation, increased academic achievement, and sustainable educational change. 相似文献

Anatomy teaching is seeing a decline in both lecture and laboratory hours across many medical schools in North America. New strategies are therefore needed to not only make anatomy teaching more clinically integrated, but also to implement new interactive teaching techniques to help students more efficiently grasp the complex organization of the human body. Among the difficult anatomical concepts that students struggle to understand, the anatomy of the peritoneal cavity with its complex projections of peritoneum could benefit strongly from new learning aids. In this report, an innovative teaching tool is presented to engage students during both lecture and laboratory, and help them build three‐dimensional (3D) mental maps of peritoneal cavity. The model consists of a patchwork of mesenteries and gut made from colored cloth stitched together onto a T‐shirt to denote the origin and outflow of each peritoneum projection. As the lecturer wears the life‐size model, the students can appreciate the 3D organization of the peritoneal cavity on a living body. In addition, the T‐shirt model can be used in parallel with dissection to ensure a strong reinforcement of the spatial understanding of the peritoneal cavity.

Many studies have reported on the perceptions of medical students toward dissection. It is important to understand the feelings and symptoms experienced during dissection so that they can be adequately handled. Prior to dissection, first year students are given lectures on aspects of dissection, death and dying, and death rituals in various cultures. Two separate questionnaires, one given during the first week of dissection and another given one month into the program were then completed anonymously by dissection groups. The questions were designed to be open‐ended, thereby encouraging group discussion amongst students. The questionnaires were used to determine the perception of students to dissection and to discover if these perceptions change during the dissection program. The first questionnaire revealed that students do experience fears and anxiety prior to and at the beginning of dissection; however, most of these fears dissipated by the time of the second questionnaire. One month into dissection students cited talking to peers as their main coping mechanism and fewer students mentioned emotional detachment from their cadaver as a coping mechanism, as was the case in the first questionnaire. Dissection was perceived as a positive experience by our student cohort and most students cited the main advantage of dissection as the ability to visualize organs in three dimensions. The comprehensive answers received from the students indicated that thorough discussion of feelings amongst peers occurred, introducing students to an important coping mechanism at an early stage of their learning.

AbstractIn South Africa the education system for black children is fraught with problems. These problems are the direct result of apartheid and have been compounded by poverty and illiteracy. In this article the problem of poorly qualified or unqualified teachers is discussed especially with regard to the teaching of map skills to children in their fifth school year. The project team needed to develop affordable materials which could be used in large classes by teachers after a very short period of training. Books and other materials which are available commercially were examined, but for various reasons were found to be unsuitable for local conditions. After determining the extent of the problem, the project team followed a grassroots process of developing a flip chart which teachers learnt to use with confidence and which enabled pupils to master the concepts and skills necessary for understanding a map. 相似文献
