Many sports associated with anterior cruciate ligament (ACL) injury require athletes attend to a ball during participation. We investigated effects of attending to a ball on lower extremity mechanics during a side-cut maneuver and if these effects are consistent for males and females. Sagittal and frontal plane hip and knee kinematics and joint moments were measured during side-cut maneuvers in 19 male and 19 female National Collegiate Athletic Association division III basketball players. Participants also experienced two side-cut conditions that required attention to a ball. Our results did not indicate that the effect of attention varies with gender. However, during side-cut conditions while attending to a ball, internal knee adductor moment was 20% greater (p = 0.03) and peak knee flexion angle was 4° larger (p < 0.01). Females demonstrated 5° less hip flexion (p = 0.046), 12° less knee flexion (p < 0.01), and 4° more knee abduction (p = 0.026) at initial contact during all side-cut conditions than males. Attention to a ball may affect lower extremity mechanics relevant to ACL injury. The validity of laboratory studies of lower extremity mechanics for sports that include attention to a ball may be increased if participants are required to attend to a ball during the task. 相似文献

Design activities, when embedded in an inquiry cycle and appropriately scaffolded and supplemented with reflection, can promote the development of the habits of mind (scientific abilities) that are an important part of scientific practice. Through the Investigative Science Learning Environment (ISLE), students construct physics knowledge by engaging in inquiry cycles that replicate the approach used by physicists to construct knowledge. A significant portion of student learning occurs in ISLE instructional labs where students design their own experiments. The labs provide an environment for cognitive apprenticeship enhanced by formative assessment. As a result, students develop interpretive knowing that helps them approach new problems as scientists. This article describes a classroom study in which the students in the ISLE design lab performed equally well on traditional exams as ISLE students who did not engage in design activities. However, the design group significantly outperformed the non-design group while working on novel experimental tasks (in physics and biology), demonstrating the application of scientific abilities to an inquiry task in a novel content domain. This research shows that a learning environment that integrates cognitive apprenticeship and formative assessment in a series of conceptual design tasks provides a rich context for helping students build scientific habits of mind. 相似文献

The study was designed to test several hypotheses derived from intergroup theory concerning the effects of the presence of a novel social category on the formation of intergroup attitudes. Elementary school children (N = 61; aged 6–9) were given measures of classification skill and self-esteem and assigned to 1 of 3 types of school classrooms in which teachers made: (1) functional use of "blue" and "yellow" groups assigned on the basis of a biological attribute, (2) functional use of "blue" and "yellow" groups assigned on the basis of a random drawing, or (3) no explicit groups (despite the presence of blue and yellow groups). After 4 weeks, children completed measures of intergroup attitudes and behavior. As predicted, the functional use of color groups affected children's attitudes toward group members, with children showing consistent biases favoring their own group. Children with higher levels of self-esteem showed higher levels of intergroup stereotyping. 相似文献

Since enactment of Public Law 94-142, residential schools for d/Deaf or hard of hearing (d/Dhh) students have lost enrollment to public schools. Public school counselors now must meet d/Dhh students' counseling needs. There is little literature on if and how counselors are doing this. The present study used a survey to evaluate the job satisfaction and expectations of 22 counselors working with d/Dhh students in programs across the United States. Follow-up interviews were conducted with 6 participants functioning as counselors for d/Dhh students. Results indicated that the counselors were generally pleased with their role, which, however, diverged markedly from the American School Counselor Association (2003) national model. The interviews revealed 5 themes that may be unique to counselors serving d/Dhh students in public schools: Authority Based on Experience, Director 相似文献

This case study explores student perceptions and experiences of advising at a New Zealand university. It considers the implications arising from the students’ responses and also investigates the influence of students’ demographic characteristics on perceptions of advice. Both first‐ (n = 191) and final‐ (n = 171) year cohorts of students were surveyed to determine why they chose particular courses, what advice they received and how aware they were of various support services. Although students were happy overall with the advice received, many had little or no expectations of the type of advice they should be receiving. The main sources of advice were the University enrolment pack, family and University School’s Liaison Officers. Academic advisers were less well used as a source of advice, even during later years of study. Advisers need to be educated about particular advising issues related to first‐generation students, part‐time students and international students. Many students had a career path in mind so it is important to provide holistic developmental academic advice that includes future career options. 相似文献

The present longitudinal study measured student adjustment to higher education, comparing 50 participants from alternative
schools (Steiner, Montessori, New Schools) with 80 students from the traditional school system. We hypothesized that students
from alternative schools adapt better, because of greater perceived social support, academic self-efficacy, and task-oriented
coping styles. Measures were taken during the last school year (baseline characteristics), and at the beginning of the first
and last terms of the first year in higher education. The quality of adjustment was assessed through academic results, and
physical and psychological well-being. The following instruments were used: the State-Trait Anxiety Inventory by Spielberger
(1983), the 13-items Depression Inventory by Beck et al. (1961), the Coping Inventory for Stressful Situations by Endler and Parker (1990), and semi-directed interviews. Results show that students from alternative schools adjust better to higher education: they
report less anxiety and depression symptoms, and show greater life satisfaction and academic achievement. 相似文献

Delayed conditional discriminations in which a sample indicates which comparison stimulus is correct have typically been used
in working memory research with animals. Following acquisition with no (0-sec) delay between the offset of the sample and
the onset of the comparison stimuli, delays of variable duration are introduced. The resulting retention functions are taken
as a measure of memory. We suggest that, in addition to memory loss due to the delay, the comparison of matching accuracy
at the 0-sec training delay with relatively novel test delays may produce a generalization decrement that varies as a function
of increasing delay. We tested this hypothesis by training pigeons with a mixed delay procedure from the start and found that
the retention functions for these pigeons were significantly shallower than those for a control group trained with 0-sec delays
and tested with longer delays, and, although reduced in magnitude, the differences persisted for as many as 15 sessions. We
propose that a measure of animals’ working memory can be obtained uninfluenced by a generalization decrement if they have
received comparable training with all of the delays that are tested. 相似文献

This study examines libraries’ nursing collections using the Interagency Council on Information Resources in Nursing's Essential Nursing Resources’ (ENR) 26th edition. An inventory of the online collections of 235 libraries was assembled and compared to free, government, or National Library of Medicine resources and licensed resources from the ENR. The top five resources listed on library websites in descending order were MEDLINE, CINAHL, ERIC, PsycINFO, and Google Scholar. The availability of specialized resources varied, based on factors such as the level of nursing degree at each institution or the libraries’ National Network of Libraries of Medicine membership statuses. 相似文献

The use of technology to facilitate education and the provision of an entire higher education degree has exploded in the last two decades. Social work educators have been a part of that trend and have started to utilize distance education (DE) technologies. There is a growing literature regarding the efficacy of DE instruction in social work, and scholars are actively developing best practices. However, there is little research in general to support the cost of DE, no cost studies in social work, and none comparing costs of DE delivery to costs associated with a face-to-face program. This study hopes to fill this gap by providing an analysis of the direct costs of an MSW DE program in comparison to similar costs of a face-to-face program. 相似文献
