Increasing student financial aid programs: A misdirected means of expanding access?

Federal and state student financial aid programs have increased substantially in past years. Such programs have clearly provided greater access to postsecondary education for low income and minority students.However, data recently collected in Los Angeles indicate that additional financial aid may have a diminishing impact on increasing access. The Los Angeles study, commissioned by the California Legislature, revealed that low levels of academic achievement, inadequate information, and inflexible admission policies are greater barriers to college for the poor than financial need.Educational opportunity programs, which provide counseling, tutoring, and information services, should become increasingly important in addressing nonfinancial barriers. Yet such programs are often politically unattractive to legislators and administrators who view student grant programs as simpler and less costly.

How do college students solve proportion problems?

Problems which could be solved using proportional reasoning were administered nationwide by college faculty to their own science classes during a three year period. The reasoning of more than 8000 students covering three sections of the country was classified as concrete, transitional, or formal using Piagetian categories. Data from the West closely replicated that from the Midwest on similar metric conversion tasks. Student performance changed noticeably with a different problem format. The percentages of students using a ratio formula, ratio attempt, or intuitive methods of solution held approximately constant over time, task, and section of the country. The data shows the use of additive and conversion methods of solution depends upon the problem presentation.     

Child care quality: centers and home settings that serve poor families

The effects of center-based care on early development, outside of carefully controlled demonstration programs, appear to be positive yet often modest for children from low-income families. But little is known about variation in the quality of centers and preschools found among low-income neighborhoods. Evidence also remains scarce on the observed quality of home-based care, the settings that most children attend and into which large infusions of federal dollars are now directed. This paper reports on the observed quality of 166 centers and 187 nonparental home settings (including family child care homes and kith or kin providers) serving children in five cities situated in California, Connecticut, or Florida. Centers displayed higher mean quality as gauged by provider education and the intensity of structured learning activities, compared to home-based settings, but did not consistently display more positive child–provider interactions. Great variability among centers and home-based settings was observed, including between-city differences. Second, we found that contextual neighborhood attributes accounted for the quality of providers selected more strongly than family-level selection factors. Mothers with stronger verbal abilities (PPVT scores) did select higher quality centers; those employed longer hours each week relied on kith and kin providers with lower education levels. Interrelationships among different quality measures are detailed. The policy implications of such wide disparities in center and home-based care quality are discussed, including how states could more carefully strengthen regulatory or quality improvement efforts.     

Child Care Selection Under Welfare Reform: How Mothers Balance Work Requirements and Parenting

This paper examines the reasoning and experiences of mothers in selecting child care while trying to meet welfare-to-work requirements. Three theoretical positions that have been used to look at child care selection -rational choice, structuralist, and cultural - are examined and critiqued in light of a structural developmental psychology perspective. The paper then reports on semi-structured, open-ended interviews with seven mothers from three different ethnic groups—African- American, Anglo, and Latina—who range in age from 21 to 42. Interviews covered a 15-month period of time following the mothers' enrollment in a welfare- to-work program. The major finding is that mothers have hierarchically ordered criteria for evaluating child care possibilities, and the preeminent criteria is that they trust the child care provider to keep their children safe and well cared for. Structural constraints on the mothers choices are also analyzed. The findings in this article suggest that policy makers should focus on issues of trust and legitimacy of child care providers, as well as on more traditional concerns of supply and educational quality.
