Three studies are reported of children and youth aged 11–19 years (n?=?3478) examining the nature of beliefs about athletic ability. Drawing on related research in academic, moral and stereotyping domains, development of a psychometric instrument assessing athletic ability beliefs is detailed. Support was found for a multidimensional hierarchical structure that is invariant across age and gender. Confirmatory factor analysis revealed a structure comprising two higher-order factors of entity and incremental beliefs underpinned by beliefs that athletic ability is stable and a gift (entity), and is open to improvement and can be developed through learning (incremental). Incremental beliefs, indirectly through a task goal orientation, and entity beliefs directly, predicted self-reported amotivation towards physical education and sport. On the other hand, enjoyment of physical activity in youth was predicted directly by task orientation and incremental beliefs. Predictions concerning the moderating role of perceived competence were not supported. Our findings highlight the importance of ability beliefs and goals in understanding the determinants of physical activity in children and youth. 相似文献

Surveys of academic staff in six universities in the UK provide insights for publishers into scholarly article and book reading patterns of academics and differences based on personal characteristics of readers. These surveys were part of the 2011 UK Scholarly Reading and the Value of the Library Study funded by JISC Collections and based on studies conducted by Tenopir and King since 1977. Scholarly articles, especially those obtained from the library's e‐journal collections, are a vital part of academic work. Reading patterns of books are quite different than articles; books most often come from personal print collections. Book readings are still important for research and teaching, however, especially for humanists. Academics come into contact with multiple sources of information every day and therefore, convenience and easy access are important factors. Knowing more about academic reading patterns helps publishers and librarians design more effective journal systems and services now and into the future. 相似文献
