In this paper, we investigate the question of what assessment tools are being used in practice by United States computing programs and what the faculty doing the assessment think of the tools they use. After presenting some background with regard to the design, implementation, and use of assessment, with particular attention to assessment tools, we report on the results of two surveys, distributed to the SIGCSE mailing list and to the chairs of all ABET-CAC accredited computer science programs. This combination of community practice and advice for non-experts could be helpful to someone designing, evaluating, or improving an assessment plan.  相似文献

The goal of the study was to investigate how teachers' reflection and feedback asking – two crucial components of professional development – can be explained by occupational self-efficacy, learning goal orientation and transformational leadership. A survey study with data from 456 teachers from a Dutch College for Vocational Education and Training shows that occupational self-efficacy and learning goal orientation are positively related to reflection and feedback asking. Furthermore, learning goal orientation mediates the relationships between occupational self-efficacy and reflection and asking feedback. Finally, the positive relationship between transformational leadership and reflection and asking feedback appears to depend on learning goal orientation.  相似文献

The analysis of variability both within and between performers can reveal important information about how athletes satisfy situational constraints. Transitory changes in the basketball free-throw shot were examined across different stages in skill development. Six female basketball players were selected, representing a range of playing expertise (pretest: 0-90% baskets scored). Each participant was video recorded performing 30 shots. Contrary to predictions, there was not a clear pattern of a reduction in trajectory variability with increasing skill level. However, improvements in skill level were associated with an increasing amount of intertrial movement consistency from the elbow and wrist joints. It is suggested that the angular motions of the elbow and wrist joints were compensated for each other toward the end of each throw to adapt to subtle changes in release parameters of the ball.  相似文献

The purpose of this study was to compare the reverse two and one half somersault dive in a tuck position (305C) performed by females (n = 24), and the reverse two and one half somersault dive in a pike position (305B) performed by males (n = 21), to determine changes required by females to successfully perform 305B. Key performance variables in reverse dives were also compared to those of forward dives. Video data of the dives performed at the 1999 FINA World Diving Cup were captured and digitised to obtain times and postures of the divers at specific events including hurdle landing, takeoff, and entry. Estimates of hurdle flight height and mass-normalised work done on the springboard were obtained from hurdle and flight times. The males did more work on the springboard to achieve greater height and rotation than females. Females performing 305C had less hip and knee flexion at hurdle landing than males performing 305B and took longer to achieve maximum hip flexion after takeoff from the springboard. To progress from 305C to 305B females need to adjust their techniques to put more energy into the system. Desirable changes include increased height in the hurdle and increased hip and knee flexion prior to hurdle landing. Comparison of results for reverse dives with data previously presented for forward dives indicated that divers are more limited in the number of somersaults and dive position in reverse dives than forward dives despite equivalent or better height in reverse dives than forward dives.  相似文献

Background: Retirement from professional sport has been recognised as a major psychological stressor, and there is a need to identify factors that increase the risk of mental health problems after career termination. The current study examined associations between career-ending injury, chronic pain, athletic identity, and depressive symptomology in retired professional footballers. Methods: A cross-sectional study was performed with 307 retired male footballers who had played within a professional United Kingdom league. Participants completed measures of depressive symptoms (Short Depression-Happiness Scale), chronic pain (Pain Intensity Numerical Rating Scale), and athletic identity (Athletic Identity Measurement Scale), and reported their reasons for retirement. Results: A total of 48 participants (16%) met the cut-off score for possible cases of clinically relevant depression. These participants were more recently retired, and had higher athletic identity than those without depressive symptoms. Former players with depressive symptoms were more likely to cite injury as a retirement reason, and report higher levels of ongoing injury-related pain. Multivariate logistic regression revealed that the presence of depressive symptoms was independently associated with retirement through injury (OR?=?3.44; 95% CI?=?1.39, 8.51), higher pain levels (OR?=?1.38; 95% CI?=?1.02, 1.86), and increased athletic identity (OR?=?1.28; 95% CI?=?1.14, 1.44). Conclusions: Career-ending injury is strongly associated with higher odds of depressive symptomology during retirement, while experiencing chronic pain, and maintaining a high sense of athletic identity, are additional potential contributors.  相似文献

Relationships between girls and women have typically been explored through the lexicon of ‘friendship’ or, where there is a presence of sexual desire, ‘lesbian’. This article suggests the complexity and impact of female (same-sex) sociality, and its relationship to heteronormativity and power dynamics between girls and women runs deeper than the terms ‘friendship’ or ‘lesbian’ give rise to. Exploring social and power dynamics amongst girls and women, this article explores how gender is policed and negotiated within a framework of homosociality. Drawing on empirical research within a women's Australian Rules football team, I explore the complexity of female same-sex bonds, the negotiation of gender embodiment and performance within female homosocial spaces, and the emergence of women's own lexicons in making sense of their relationships with other women in this particular social sphere, further considering how this might be applied to other female homosocial spaces, including same-sex educational and sporting sites.  相似文献
