Effects of a professional development program on classroom practices and outcomes for Latino dual language learners

A randomized, controlled study was conducted to assess the effects of the Nuestros Niños professional development program on classroom practices and child outcomes related to language development and early literacy skills in both English and Spanish. Fifty-five teachers and 193 Latino dual language learners (DLLs) enrolled in the North Carolina More at Four Pre-Kindergarten Program participated in the study. The content of the professional development program consisted of research-based instructional practices designed to complement the core curriculum and scaffold learning for DLLs, and the format included professional development institutes, individualized consultation, and community of practice meetings. The results showed that the intervention led to measurable improvements in both the overall quality of teachers’ language and literacy practices as well as those specific to working with Latino DLLs, and greater gains in children's phonological awareness skills in their primary language.

Characteristics of children referred to school psychologists: A discriminant analysis

This study compared characteristics of 114 elementary school children of average intelligence who had been referred for psychological services with 120 children of average intelligence who had not been referred. Variables included, sex, relative age, race, socioeconomic status, familial stability, achievement test scores, and intraschool factors. At the primary level, significant differences were found between the groups in terms of sex and relative age. Boys were referred 4 times as frequently as girls, and 16 times as many boys within the relatively youngest group were referred as girls within the oldest group. The total groups were successfully discriminated using math achievement, sex, race, and father of the same name in the household. The variables that best discriminated the primary level groups included sex, relative age, father with the same name in the household, and having attended the same school the previous year. Implications and possible preventative measures are discussed.     

Connecting girls and science: A feminist teacher research study of a high school prenatal testing unit

In this article, I explore how a dozen high-school sophomore girls expressed their relationship to and understanding of prenatal testing, and its possible place in their lives and in the lives of others, in the context of a short unit on prenatal testing during a semester-long course in human genetics. The data come from an assignment designed to help students bring their understanding of prenatal testing into the realm of personal choice, as well as practice applying the science of chromosomal inheritance. Difference feminism is used to develop themes evident in these girls' talk about prenatal testing. The instructional choices made were based on difference feminism, which implies that girls would be interested in science that connects to human bodies, children, and traditional women's responsibilities. This claim is elaborated on and applied by this study, in which I concentrate on the question: How can difference feminism help us better to hear and comprehend high school girls' relationships with reproductive technology, their own bodies, and their own lives? I propose that focusing on girls' lives and knowledge is a way to consider alternatives in curricular content, in addition to helping us learn how to help more girls connect with science. © 1998 John Wiley & Sons, Inc.

Potential mediating pathways through which sports participation relates to reduced risk of suicidal ideation

Suicide ranks as the third leading cause of death for American youth. Researchers examining sport participation and suicidal behavior have regularly found inverse relationships. This study represents the first effort to test a model depicting potential mechanisms through which sport participation relates to reduced risk of suicidal ideation. The participants were 450 undergraduate students. Measures assessed participants' involvement in university-run sports and other activities; frequency of physical activity; and perceived social support, self-esteem, depression, hopelessness, loneliness, and suicidal ideation. Regression analyses confirmed a path model and tested for mediation effects. Vigorous activity mediated relationships between sport participation and self-esteem and depression; and self-esteem and depression mediated the relationship between vigorous activity and suicidal ideation. Social support mediated relationships between sport participation and depression, hopelessness, and loneliness; and each of these risk factors partially mediated the relationship between social support and suicidal ideation. However no variable fully mediated the relationship between sport participation and suicidal ideation. This study provides a foundation for research designed to examine pathways through which sport participation relates to reduced risk of suicidal behavior.     

Migration patterns of first-time freshmen in the United States

A place-to-place migration study of first-time freshmen in American four-year colleges and universities presents student migration patterns for each of the fifty states and the District of Columbia in Fall 1986. Migration patterns of all first-time students are reviewed, but the focus of the study is first-time freshmen, the most critical population for institutional enrollment management. State-to-state matrix tables are presented that show where students come from and where they go to school for all fifty-one locations by sector of control (i.e., public and private).Presented at the 29th Annual Forum of the Association for Institutional Research, Baltimore, Maryland, May 2, 1989.
