A latent growth curve approach to investigating developmental dynamics and correlates of change in children's perceptions of physical competence.

In both the physical and academic domains interest has recently grown regarding developmental change in children's perceptions of competence. Recent advances in statistical methodology, such as latent growth modeling, enable the researcher to analyze developmental trends from both an inter- and intraindividual perspective, thus serving to increase our understanding of correlates of change in perceived competence. Using latent growth modeling, the purpose of the present study was to investigate developmental change in children's perceived competence at physical skills, examining maturational factors and chronological age as possible correlates of change. Subjects were male adolescents (N = 94). Data were collected during the child's sixth, eighth, and ninth grade school years. Results revealed a good fit for the hypothesized model, which specified mean level changes in the variables over time and an interrelationship among the latent chronometric common factors. Although a significant relationship existed between maturation and perceived competence, no significant relationship was evident between chronological age and perceived competence. Findings are discussed with particular reference to the utility of latent growth curve models for assessing developmental processes at both the inter- and intraindividual level.     

Work-based antipoverty programs for parents can enhance the school performance and social behavior of children

We assess the impact of the New Hope Project, an antipoverty program tested in a random assignment experimental design, on family functioning and developmental outcomes for preschool- and school-aged children (N = 913). New Hope offered wage supplements sufficient to raise family income above the poverty threshold and subsidies for child care and health insurance to adults who worked full-time. New Hope had strong positive effects on boys' academic achievement, classroom behavior skills, positive social behavior, and problem behaviors, as reported by teachers, and on boys' own expectations for advanced education and occupational aspirations. There were not corresponding program effects for girls. The child outcomes may have resulted from a combination of the following: Children in New Hope families spent more time in formal child care programs and other structured activities away from home than did children in control families. New Hope parents were employed more, had more material resources, reported more social support, and expressed less stress and more optimism about achieving their goals than did parents in the control sample. The results suggest that an anti-poverty program that provides support for combining work and family responsibilities can have beneficial effects on the development of school-age children.     

An assessment of the benefits of the diffusion of an innovation

A benefit-cost analysis of an innovative pharmaceutical in a relatively small market in the United Kingdom was carried out. The market was that for anti-tuberculosis drugs. The impact of the innovation, as it proceeded through its commercial life cycle, on competing products and on alternative hospitalisation therapy was evaluated. Despite the high cash price of the product relative to those it replaced this price was dwarfed by the benefits provided.     

Rationalizing teacher roles in developing and assessing physical literacy in children

PROSPECTS - Physical literacy serves as the foundation for several skills or attributes needed for lifelong physical activity participation. Based on its connection to physical activity, physical...     

Negotiating school-university partnerships: Participants' voices in co-reform

Although many educators recognize the importance of voice, fostering voice in those who have traditionally been voiceless has been difficult. This article, like the program that it describes, tackles that challenge by having participants speak for themselves. Specifically, the participants speak about their involvement in the first year of an alternative teacher education project. In describing their involvement, the participants focus on their roles and relationships as well as the type of partnership and collaboration that emerged from this project.
