Students' motivation is a vital determinant of academic performance that is influenced by the learning environment. This study aimed to assess and analyze the motivation subscales between different cohorts (chiropractic, dental, medical) of anatomy students (n = 251) and to investigate if these subscales had an effect on the students' anatomy performance. A 31-item survey, the Motivated Strategies for Learning Questionnaire was utilized, covering items on intrinsic and extrinsic goal orientation, task value, control of learning belief, self-efficiency for learning and performance, and test anxiety. First-year dental students were significantly more anxious than chiropractic students. Second-year chiropractic students attached more value to anatomy education than second-year medical students. The outcome of this research demonstrated a significant relationship between first- and second-year chiropractic students between anatomy performance and motivation subscales controlling for gender such as self-efficacy for learning and performance was (β = 8, CI: 5.18–10.8, P < 0.001) and (β = 6.25, CI: 3.40–9.10, P < 0.001) for first year and second year, respectively. With regards to intrinsic goal orientation, it was (β = 4.02, CI: 1.19–6.86, P = 0.006) and (β = 5.38, CI: 2.32–8.44, P = 0.001) for first year and second year, respectively. For the control of learning beliefs, it was (β = 3.71, 95% CI: 0.18–7.25, P = 0.04) and (β = 3.07, CI: 0.03–6.12, P = 0.048) for first year and second year, respectively. Interventions aimed at improving these motivation subscales in students could boost their anatomy performance.  相似文献

The importance of patient-centered decisions is embedded throughout clinical practice. The principle that the patient is at the center of all decisions has helped form the contemporary approach to death and dying. The concept of a “good death” will naturally mean different things to different individuals, but is based on the foundation of being pain free, comfortable, and able to make informed decisions. Potential donors are faced with many personal, ethical, and often spiritual considerations when they come to think about their wishes after death. One consideration is that of a “good death.” This article explores how the concept of a “good death” may be applied to anatomy. Where first-person consent is in place, the motivating factors frequently include the wish for others to learn from the donation, and this notion may form part of the “good death” for the donor. Such motivations may impact positively on how students feel about dissecting and may provide comfort, assuaging feelings of discomfort, and allowing students to focus on anatomical learning. For donors where second-person consent is in place, the concept of a “good death” must depend on whether the individual wanted to donate their body in the first instance. The notion of a “bad death” may also be considered with body donation where no consent for donation is in place. This article proposes that there is ultimately a place for the concept that a “good death” may involve an individual donating their body to medical education.  相似文献

This study investigated trajectories of individual and vicarious online racial discrimination (ORD) and their associations with psychological outcomes for African American and Latinx adolescents in 6th–12th grade (N = 522; Mgrade = 9th) across three waves. Data were analyzed using growth mixture modeling to estimate trajectories for ORD and to determine the effects of each trajectory on Wave 3 depressive symptoms, anxiety, and self-esteem. Results showed four individual and three vicarious ORD trajectories, with the majority of participants starting out with low experiences and increasing over time. Older African American adolescents and people who spend more time online are at greatest risk for poor psychological functioning.  相似文献

The number-line task has been extensively used to study the mental representation of numbers in children. However, studies suggest that proportional reasoning provides a better account of children’s performance. Ninety 4- to 6-year-olds were given a number-line task with symbolic numbers, with clustered dot arrays that resembled a perceptual scaling task, or with spread-out dot arrays that involved numerical estimation. Children performed well with clustered dot arrays, but poorly with symbolic numbers and spread-out dot arrays. Performances with symbolic numbers and spread-out dot arrays were highly correlated and were related to counting skill; neither was true for clustered dot arrays. Overall, results provide evidence for the role of mental representation of numbers in the symbolic number-line task.  相似文献

In an era when children’s rights are paramount, there are still few practical examples to guide us when seeking informed consent from children. This article therefore makes a significant contribution to the field by examining three practical approaches to negotiating informed consent with young children under 6 years old. We draw on researcher field notes, images and observations from four research projects that employed creative methods for seeking informed consent from young children. We take a reflexive approach, considering how successful the three techniques have been in facilitating young children’s decision-making around research participation. Our findings suggest that innovative approaches to informed consent create spaces for children to engage in dialogue and questioning about the research project. However, in order for the approaches to be meaningful, they need to be pedagogically appropriate to the maturity and capabilities of the children. We also demonstrate that, irrespective of the approach devised, researchers have a responsibility to ensure consent is continuously negotiated throughout the project through reflexive questioning.  相似文献

Large urban school districts often struggle with hierarchy, fragmented processes and cultures whereby organisational silos between school and central office staff serve as a major barrier for reaching the desired strategic goals of improving student achievement. In addition, school district staff are undergoing change requiring leaders and staff in these organisations to adapt and build their capacity to support changing demands. However, little attention is paid to how to build the necessary systems and learning environments to support capacity building and leader development. This article reports on an action research study using mixed methods that reveal how central office leaders and school principals break down organisational silos to build a culture of learning using learning organisation principles. Using the Dimensions of the Learning Organization Questionnaire (DLOQ) short form, participants completed questions related to the school district's capacity for learning. Data from the survey and interviews outline key findings that illustrate how the learning organisation framework served as a model to create the organisational conditions and culture to enable support and cooperation for learning, capacity, change and improvement to occur. This action research case study is a look at one organisation's approach to addressing a gap in learning organisation research in the area of learning organisation interventions. In addition, it extends current research on schools as learning organisations with an example of data-informed change in one large school district in the southern United States.  相似文献

Background:Participation in physical activity supports greater cardiorespiratory fitness(CRF),a correlate of cognitive control.However,the relationship between muscular fitness(MF)and cognitive control is less clear.The present study investigated the differential relationship of CRF and MF with cognitive control in older adolescents.Methods:This cross-sectional study involved students(1517 years old,n=541,43%female)from 20 secondary schools who completed tests of inhibition(modified flanker task),working memory(n-back task),CRF(Progressive Aerobic Cardiovascular Endurance Run),and MF(standing long jump and push-up test).Multilevel analyses tested the association between CRF or MF and cognitive outcomes while accounting for the influence of the other fitness variable and relevant demographic factors.Results:CRF predicted response accuracy during incongruent flanker trials,the condition requiring greater inhibition.For the working memory task,CRF predicted greater target accuracy and greater d’scores on the 1-back task,requiring lesser amounts of working memory.In the 2-back task,which requires greater amounts of working memory,CRF also predicted greater target and non-target accuracy and d’scores.Comparatively,MF did not predict any cognitive outcomes after adjustment for CRF.Conclusion:CRF was selectively related to better performance during task conditions that require greater amounts of inhibition and working memory.This finding suggests that CRF,but not MF,may benefit cognitive control in older adolescents.This selective influence of CRF on older adolescents’cognition highlights the value of aerobic physical activity.  相似文献
