Physics and geoscience consistently rank near the bottom among all disciplines in their ability to attract and retain African American students. Before delving into these trends, it is important to establish a context for discussing the data and their implications. African Americans comprise 12.4% of the U.S. population, but their representation…

Extensive research indicates that there are more boys than girls who are struggling readers, although considerable variation in gender ratios has been reported as a result of a lack of consensus in defining and measuring poor reading. The purpose of this study was to establish stable and consistent gender ratios for poor reading using a single…

This article describes a collaborative teacher-researcher project exploring how 4-8-year-old children understood and worked with new forms of literacy at home and at school.

Having a child is a major determinant of geographic mobility. Little is known, however, about the opposite process--whether geographic mobility is a determinant of fertility.

Factor analysis identified two race-related reasons for college choice, the race focus of the institution…

In an attempt to increase applications from low-income students, some selective 4-year colleges are developing programs to target and attract low-income students.

If major search engines show biased coverage it can be considered a significant economic and political problem because…

The purpose of this article is to analyze interpersonal problems among adult learners in three family literacy programs and to identify how these tensions were connected to place or distinctive community contexts.
