Grades often decline during the high school transition, creating stress. The present research integrates the biopsychosocial model of challenge and threat with the implicit theories model to understand who shows maladaptive stress responses. A diary study measured declines in grades in the first few months of high school: salivary cortisol (N = 360 students, N = 3,045 observations) and daily stress appraisals (N = 499 students, N = 3,854 observations). Students who reported an entity theory of intelligence (i.e., the belief that intelligence is fixed) showed higher cortisol when grades were declining. Moreover, daily academic stressors showed a different lingering effect on the next day's cortisol for those with different implicit theories. Findings support a process model through which beliefs affect biological stress responses during difficult adolescent transitions. 相似文献

AbstractInterlibrary loan (ILL) services receive requests for resources that are available locally and form a major portion of canceled requests. The purpose of this study is to examine the relationship between requests canceled due to local availability and three aspects to identify impacts on ILL. The authors explored library service aspects such as collection format, the link resolver knowledge base, and discovery system functionality for potential influence on requests for locally available resources. Quantitative methods were used to identify evidence of different aspects’ impact through analysis of ILL borrowing request data. The most important finding was that the discovery system had impact on ILL services by improving retrievability of locally available resources published recently. The results suggest that a modern discovery system can efficiently provide more relevant results sourced from a carefully curated set of authoritative resources, save users’ time to access available materials, and reduce library staff members’ time and effort. This study will be helpful to libraries through its analysis of library services that impact the cancelation of ILL requests due to local availability and how those services may influence service improvement. 相似文献

Understanding basic human anatomy can be beneficial for all students, regardless of when, or if, they will later undertake a formal course in the subject. For students who are preparing to undertake a formal anatomy course, educational comics on basic anatomy can serve as a concise and approachable review of the material. For other students, these comics can serve as a helpful and fun introduction to the human body. The objective of the comics in this study was to promote an understanding of fundamental human anatomy through self‐learning among students. Based on the authors' previous teaching experience, these anatomy comics were produced in a simple, direct style. The comics were titled after the two main characters, “Anna” (a girl) and “Tommy” (a boy). These comics were then presented to groups of elementary school students, high school students, premedical students, and medical students to assess the comics' ability to enhance student interest and comprehension of basic anatomy. Quiz scores among high school students and premedical students were significantly higher among participants who read the educational comics, indicating a deeper comprehension of the subject. Among medical students, close reading of the comics was associated with improved course grades. These educational anatomy comics may be helpful tools to enrich a broad spectrum of different students in learning basic human anatomy.

This paper examines the relationship between altruism and positive illusion, as formulated by Taylor and Brown (1988). It
was predicted that, compared to the non-exemplary, general population, exemplary altruists would exhibit a higher level of
positive illusion, which, in turn, suggests a higher level of mental health. Forty exemplary altruists and forty non-exemplary
altruists were assessed in terms of positive illusion and compared with each other using Hotelling T2followed by univariatet-test. The results supported the prediction that exemplary altruists showed higher scores in terms of positive illusion than
that of the non-exemplary general population. The implications of the results are discussed. 相似文献

Three studies examined the effects of receiving fewer signs of positive feedback than others on social media. In Study 1, adolescents (N = 613, Mage = 14.3 years) who were randomly assigned to receive few (vs. many) likes during a standardized social media interaction felt more strongly rejected, and reported more negative affect and more negative thoughts about themselves. In Study 2 (N = 145), negative responses to receiving fewer likes were associated with greater depressive symptoms reported day-to-day and at the end of the school year. Study 3 (N = 579) replicated Study 1’s main effect of receiving fewer likes and showed that adolescents who already experienced peer victimization at school were the most vulnerable. The findings raise the possibility that technology which makes it easier for adolescents to compare their social status online—even when there is no chance to share explicitly negative comments—could be a risk factor that accelerates the onset of internalizing symptoms among vulnerable youth. 相似文献

At community colleges, student preparedness for college-level work is a significant initial barrier. Over 70% of community college students are reported to be inadequately prepared for college mathematics. Because students need to pass college-level math in order to enroll in subsequent courses required for their majors or to complete general requirements for their degrees, community colleges have searched for instructional redesign approaches that can produce more positive results. This study reports on a developmental math redesigned curriculum that dramatically improved student course completion rates and resulted in some advantage in enrolling in college-level math compared with their peers in the traditional developmental sequence. Results are discussed in terms of their practical significance and implications for further research. 相似文献

In the Visible Korean project, serially sectioned images of the pelvis were made from a female cadaver. Outlines of significant structures in the sectioned images were drawn and stacked to build surface models. To improve the accessibility and informational content of these data, a five‐step process was designed and implemented. First, 154 pelvic structures were outlined with additional surface reconstruction to prepare the image data. Second, the sectioned and outlined images (in a browsing software) as well as the surface models (in a PDF file) were placed on the Visible Korean homepage in a readily‐accessible format. Third, all image data were visualized with interactive elements to stimulate creative learning. Fourth, two‐dimensional (2D) images and three‐dimensional (3D) models were superimposed on one another to provide context and spatial information for students viewing these data. Fifth, images were designed such that structure names would be shown when the mouse pointer hovered over the 2D images or the 3D models. The state‐of‐the‐art sectioned images, outlined images, and surface models, arranged and systematized as described in this study, will aid students in understanding the anatomy of female pelvis. The graphic data accompanied by corresponding magnetic resonance images and computed tomographs are expected to promote the production of 3D simulators for clinical practice.
