Sixty-four neglected and abused children with a mentally retarded parent seen from one to seven years earlier, were followed to determine placement outcomes. At the time of follow-up, 11 of 64 children remained with their low functioning parents. Six children had been relinquished voluntarily for adoption and courts had terminated parental rights for 34, resulting in a total of 40 who had been adopted. Nine children were in foster care at the time of the study; two had been awarded to their nonretarded parent following divorce; and two had died. All families had received public financial assistance and medical care and used an average of 10 other services per family. Because of their cognitive limitations, most of these retarded parents were unable to benefit sufficiently from community services to enable them to care for their children. These findings point up the need for a mechanism whereby the retarded adult's right to parent and the child's right to nurturance and protection may both be preserved. Until this dilemma can be resolved, decisions to terminate parental rights in such cases should be made more quickly.  相似文献

Improving science education is often regarded as a priority for developing countries in order to promote longterm economic development. Thus initiatives, both government and foreign-aid sponsored, aimed at improving science education in developing countries abound. However, all too often the focus of such initiatives is limited to the development of science curricula, while the details of how the curricula will be implemented at school level are often neglected. This paper represents an effort to lay the groundwork for a theory of curriculum implementation with particular reference to developing countries. We have drawn on school development, educational change, and science education literature in order to develop three constructs that could form the heart of such a theory, namely, Profile of Implementation, Capacity to Innovate, and Outside Support. Six propositions are offered to suggest how the constructs may inter-relate as a basis for the development of the theory. The implementation of the natural sciences learning area of the South African Curriculum 2005 is used to illustrate the emerging theory.  相似文献

The present study describes the development and validation of an instrument to measure volition in the exercise context. Volition describes an individual’s self-regulatory mental processes that are responsible for taking and maintaining a desirable action (e.g., exercising regularly). The scale structure was developed in an exploratory factor analysis which resulted in a reliable structure of the following six factors: Volitional Inhibition—Reasons, Volitional Inhibition—Postponing Training, Volitional Facilitation—Self-Confidence, Volitional Inhibition—Unrelated Thoughts, Volitional Inhibition—Approval From Others, and Volitional Facilitation—Coping with Failure. A sound theoretical explanation for these six factors is based on the Personal System Interaction Theory. This six-factor structure was also confirmed in a new sample in a confirmatory factor analysis, delivering an 18-item questionnaire with strong model fit and good internal consistency. In addition, the Volition in Exercise Questionnaire showed convergent validity because it was able to predict exercise participation. It showed incremental validity by explaining additional variance to the Sport Motivation Scale’s well-established predictors of exercise participation.  相似文献

ABSTRACT

Participation in youth sport is positively associated with physical fitness and performance. The purpose of the current study was to examine if physical fitness measures during childhood and early adolescence predicted high school sport participation. Participants included youth in the Michigan State University Motor Performance Study. Measures consisted of the endurance shuttle run, Wells sit-and-reach, jump and reach, standing long jump, agility shuttle run and 30-yard dash. Individual, generalized estimating equation models were used to estimate the association between each measure and the odds of participating in high school sport. For both sexes, the endurance shuttle run and agility shuttle run were related to sport participation. For boys only, the long jump and 30-yard dash were also associated with sport participation. Better physical fitness and performance across several dimensions in childhood, including those related to motor skills, enhanced the likelihood of sport participation in high school.  相似文献

Didactic and laboratory anatomical education have seen significant reductions in the medical school curriculum due, in part, to the current shift from basic science to more clinically based teaching in North American medical schools. In order to increase medical student exposure to anatomy, with clinical applicability, a student-run initiative called surgically oriented anatomy prosectors (SOAP) club was created within the extracurricular program at the Schulich School of Medicine and Dentistry, The University of Western Ontario, London, Canada. SOAP invites surgeons and residents from various surgical specialties to demonstrate, on a cadaver, a surgical procedure of their choosing. During the demonstration, the anatomy, as it relates to the surgical procedure, is discussed. The students then break into smaller groups to examine the relevant anatomy on the cadavers, during which time the discussion is broadened. The group continues the conversation in a social environment with refreshments. SOAP is one of the most popular extracurricular clubs with 65% of first and second year medical students registered as members. The high demand for SOAP, along with the positive participant feedback, may be due to its utilization of the principle of education through recreation, which seeks to provide opportunities for learning seamlessly throughout all facets of life. It also demonstrates the desire, amongst certain medical students, to learn applied anatomy, particularly within a surgical context.  相似文献
