Abstract The purpose of this study was to identify correlates of physical activity behavior in a sample of rural, predominantly African American youth. Three hundred sixty-one fifth-grade students from two rural counties in South Carolina (69% African American, median age = 11 years) completed a questionnaire designed to measure beliefs and social influences regarding physical activity, physical activity self-efficacy, perceived physical activity habits of family members and friends, and access to exercise and fitness equipment at home. After school physical activity and television watching were assessed using the Previous Day Physical Activity Recall (PDPAR). Students were classified as physically active according to a moderate physical activity standard: two or more 30-min blocks at an intensity of 3 METs (metabolic equivalents) or greater, and a vigorous physical activity standard: one or more 30-min blocks at an intensity of 6 METs or greater. According to the moderate physical activity standard, 34.9% of students were classified as low-active. Multivariate analysis revealed age, gender, television watching, and exercise equipment at home to be significant correlates of low activity status. According to the vigorous physical activity standard, 32.1% of the students were classified as low-active. Multivariate analysis revealed age, gender, television watching, and self-efficacy with respect to seeking support for physical activity to be significant correlates of low activity status. In summary, gender and the amount of television watching were found to be the most important correlates of physical activity in rural, predominantly African American youth. 相似文献

The Effects of Mastery and Competitive Conditions on Self-Assessment at Different Ages 总被引:1,自引:0,他引:1
Ruth Butler 《Child development》1990,61(1):201-210
It was hypothesized that self-evaluative accuracy will increase with age in a competitive condition, while even young children will appraise their performance quite accurately in a mastery condition. Children at ages 5, 7, and 10 working in either a match-the-standard or a competitive condition copied a drawing and then evaluated their copies. As hypothesized, competing 5-year-olds overestimated the quality of their copies, and self-assessments became less positive and better correlated with adult judgments with age. There were no age differences in self-evaluative accuracy in the mastery condition. Examination of children's explanations for their ratings and their interest in the task supported the interpretation that young children are guided by a nonnormative concept of ability, which can lead to overoptimistic perceptions of competence under competition. Older children tended to adopt normative goals and criteria for self-assessment in competition and mastery ones in the match the standard condition, and were realistic about their performance in both. 相似文献

To examine the development of triplets, 23 sets of triplets were matched with 23 sets of twins and 23 singletons (N=138). Maternal sensitivity was observed at newborn, 3, 6, and 12 months, and infants' cognitive and symbolic skills at 1 year. Triplets received lower maternal sensitivity across infancy and exhibited poorer cognitive competencies compared with singletons and twins. The most medically compromised triplet showed the lowest regulation, received lower maternal sensitivity, and demonstrated the weakest outcomes compared with siblings. Structural modeling charted three levels of influence on cognitive outcomes: direct, indirect, and contextual. The triplet ecology provides a context for assessing the relations among infant inborn dispositions, the rearing environment, and the role of exclusive parenting in development. 相似文献

Considerable research has compared how students learn science from computer simulations with how they learn from “traditional” classes. Little research has compared how students learn science from computer simulations with how they learn from direct experience in the real environment on which the simulations are based. This study compared two college classes studying introductory oceanography. One class learned using an interactive computer simulation based on a dynamic, three‐dimensional model of physical oceanography. The other class learned by spending a day on a research ship using scientific tools and instruments to measure physical properties of the ocean directly. In classes preceding and following the simulation or field experience, students performed the same exercises regarding currents and salinity, had the same instructor presentations, and did the same homework. The study found that the field experience helped contextualize learning for students with little prior experience of the ocean while the simulation made it easier for students to connect what they learned from it to other content they learned in class. These and other findings shed light on what computer simulations can and cannot help students learn, and what concepts are best learned in the real environment. © 2005 Wiley Periodicals, Inc.

Explorations in Middle School Science is a set of 72 computer-simulated laboratory lessons in life, earth, and physical Science for grades 6–9 developed by Jostens Learning Corporation with grants from the California State Department of Education and the National Science Foundation.3 At the heart of each lesson is a computer-simulated laboratory that actively involves students in doing science improving their: (1) understanding of science concepts by applying critical thinking to solve real problems; (2) skills in scientific processes and communications; and (3) attitudes about science. Students use on-line tools (notebook, calculator, word processor) to undertake in-depth investigations of phenomena (like motion in outer space, disease transmission, volcanic eruptions, or the structure of the atom) that would be too difficult, dangerous, or outright impossible to do in a live laboratory. Suggested extension activities lead students to hands-on investigations, away from the computer. This article presents the underlying rationale, instructional model, and process by whichExplorations was designed and developed. It also describes the general courseware structure and three lesson's in detail, as well as presenting preliminary data from the evaluation. Finally, it suggests a model for incorporating technology into the science classroom. 相似文献

Conclusion Environmental education at the early childhood level is about fostering a sense of appreciation and caring. The adult's role
in the process is primarily that of sharing versus instructing: “sharing enthusiasm, curiosity, and wonder” (Dighe, 1993.
p. 59). Helping young children grow in their understanding and appreciation of the natural world can greatly benefit the development
of the child and has the potential for enhancing the humanearth relationship. 相似文献

The increasing flow of Chinese graduate students to the West for advanced study is examined in the context of earlier attempts to modernize China by introducing ideas and technologies from abroad. The author suggests that the theory of communicative action associated with Habermas may provide a framework for examining the quality and nature of the intellectual interaction now taking place between Chinese scholars and their counterparts in the universities of the capitalist world. This discussion uses three episodes as points of focus; firstly the discussion over intellectual freedom on the 30th anniversary of the Hundred Flowers movement, secondly the debate over political structure reform and finally the student movement of December 1986. The author argues that these occurrences are linked to a fundamental change in the knowledge orientation of Chinese universities. 相似文献

ABSTRACT: Lifelong learning is something which one does for oneself that no one else can do for one: it is a public and personal human activity, rather than private or individualistic. One of the features of the education system is the paucity of a language for learning as process and participative experience. Personalised learning requires a sense of the worthwhileness of 'being a learner'– a virtue in the 21st century. A sense of one's own worth as a person is essential to understanding one's identity as a learner. Research suggests the human capacity to learn can be understood as a form of consciousness which is characterised by particular values, attitudes and dispositions, with a lateral and a temporal connectivity. This 'consciousness' has several dimensions which are all related to becoming a person, with a learning identity. They also enable the learner to become aware of and appropriate what is of worth and map onto the sorts of core values that learning communities espouse. Awareness of self and of one's own worth as a person is a necessary condition for 'becoming a learner' and for identifying and engaging with 'what is of worth'. Furthermore, a sense of self as a learner is formed in relationship, and understood as one learns to tell one's own story, as a participant in the conversation of the learning community. Character is the way in which we refer to that quality of personhood in which there is rooted the capacity to change and learn over time. 相似文献

Counselor-client contracts were employed to facilitate parental participation in decision making for their children who were in out-of-home care. The components of such contracts are described and an example is provided. A significant relationship was found between parental willingness to sign a written agreement and outcome. 相似文献
