Three questions are explored in this dissertation. The first is whether the executive functions of Head Start participants are improved in comparison to those of children who did not attend center-based care before attending kindergarten. By matching and comparing the outcomes of a nationally representative cohort of kindergarten children (ECLS-K:2011) grouped by the type of childcare they received in the year preceding school entry, I find that Head Start participants exhibit slightly higher cognitive flexibility scores (as well as reading and math outcomes) in comparison to highly similar children who did not experience center-based care before starting school. Children who participated in Head Start demonstrate working memory skills that are not significantly different from those of closely-matched children who experienced no center-based care, but their skills in this area are slightly weaker than those of similar children who attended school-based public pre-k or other center-based care. The second question is how math content level during kindergarten affects children with different early care experiences, with focus on Head Start participants. The use of piece-wise linear growth curves to analyze children’s development in working memory, cognitive flexibility, reading and math reveals that advanced math content in kindergarten does have a positive relationship with math and reading achievement for Head Start participants, but these students do not gain as much on average from this instructional approach as more advantaged groups do. More basic math content, such as counting has a negative association with growth in math for more advantaged groups of children. Finally, any increases in kindergarten growth rates resulting from math content do not appear to persist through first and second grades. The third question asks whether there are significant differences in the trajectories of Head Start participants according to parent nativity. In analysis using piece-wise linear growth curve models to analyze Head Start (HS) participants’ development in working memory, cognitive flexibility, reading and math, results indicate that HS participants with immigrant parents exhibit an additional surge in EF development in the period between the spring of kindergarten and the spring of second grade, later than the average kindergarten increase for all HS participants. Additionally, HS participants with immigrant parents exhibit slightly higher average growth rates in reading during kindergarten when compared to HS participants with non-immigrant parents.

The feminization of Mexican migration to the United States is increasing, and more mothers who migrate leave their children behind for long periods to be cared for by grandparents or relatives in Mexico. Women also form new families when they arrive in the United States, but continue to "care" for the children who stayed in Mexico. We know little about how transnational familial ties across the U.S. -Mexico border influence the educational trajectories of children who stay behind, are born here and are brought over from Mexico. This study asks how Mexican maternal migration has influenced care arrangements and education trajectories of the children in Mexico, comparing these to their siblings who were brought over to America or who were born in the United States. In this dissertation I address how U.S. bound Mexican maternal migration shapes and influences children and youth in both sides of the border. These families, or what refer to "transnational care constellations" include the following types of members: New York based undocumented mothers; the children they brought to the U.S. (also undocumented); their U.S. born offspring (U.S. citizens); children they have left behind in Mexico; and children's caregivers in Mexico. Drawing on ethnographic method I examine transnational caregiving practices among women with children in New York and Mexico. After recruiting twenty families to participate in my study I established three levels of engagement with participants. Eight transnational care constellations constituted the center of my qualitative research. I spent time with them in Mexico and in New York and tracked half of them for over three years. The second level of engagement happened with the other twelve families who I interviewed and observed in New York City, but visited less times in Mexico. Finally, participants who belonged to the third level of engagement were forty mothers in New York City, fathers, caregivers and over sixty children and youth in Mexico who were not matched. In addition I surveyed over 200 children between the ages of seven and sixteen in three schools in Puebla to assess the impacts of maternal remittance on school achievement. Specifically, I compare the educational experiences and social trajectories of three groups of children: the ones left in Mexico, the undocumented children and youth brought to the U.S., and those born in the U.S. The ethnographic core of my dissertation work tracked twenty transnational families who are split between Mexico and the U.S over a period of 18 months. I have traveled back and forth between different states in Mexico and New York in order to capture the dynamism of communities who are "here and there." The children and youth in what I refer to as "care constellation" share the same biological mother who has migrated to New York City, but their lives differ dramatically in terms of academic achievement and familial support.

More than one in four children under age 6 in the United State are children of immigrants, and the majority of these children are Asian and Hispanic. Despite this, there have been few studies on the early development of young children of immigrants. In particular, although healthy development in the early years of life is important in helping children get ready for school, little is known about school readiness among children in immigrant families. Therefore, this study examines school readiness among children of Asian and Hispanic immigrant mothers, with particular attention to two important characteristics of immigrant families: maternal language use and use of preschool. This study is composed of five chapters, starting with Chapter 1 that introduces the background and purpose of this study. Chapter 2 reviews the theoretical backgrounds for the association between maternal language use and the development of young children in immigrant families, and then for the role of preschool in children's school readiness. Using a nationally representative sample of children of Asian and Hispanic immigrant mothers from the Early Childhood Longitudinal Study-Birth Cohort (ECLS-B), Chapters 3 and 4 examine whether maternal language use is associated with school readiness and whether preschool plays a protective role in promoting school readiness, respectively. Finally, Chapter 5 concludes by summarizing the findings and providing implications for theory and methodology, future research, and social work and policy. In Chapter 3, this study finds generally advantages of maternal use of English and bilingualism for children's cognitive development at kindergarten entry in both Asian and Hispanic groups. It also finds, compared to children of home language Asian mothers, higher levels of pro-social behavior among those of English dominant and bilingual Asian mothers, but also higher levels of behavior problems among those of English dominant Asian mothers. Furthermore, in additional analyses, this study finds that longer residency in the U.S. is associated with higher levels of approaches to learning for children of bilingual Asian mothers and lower levels of behavior problems for children of bilingual Hispanic mothers. In Chapter 4, this study finds that attending preschool (mostly prekindergarten or other center-based care) is associated with better academic school readiness at kindergarten entry among children of Asian immigrant mothers, but not children of Hispanic immigrant mothers. This study also finds higher levels of behavior problems and lower levels of approaches to learning among children in Head Start compared to those in parental care in both Asian and Hispanic groups. In addition, this study finds beneficial associations between preschool and academic school readiness at the year of participation among children of both Asian and Hispanic immigrant mothers, but these beneficial associations do not hold up at kindergarten entry among children of Hispanic mothers, while such associations are still found at kindergarten entry among children of Asian mothers. This study also finds more pronounced beneficial influences of preschool on academic school readiness at the year of participation among children of mothers who speak their home language in both Asian and Hispanic groups, but such more pronounced benefits are gone at kindergarten entry in both groups.

The out-migration of parents has become a common childhood experience worldwide. It can confer both economic benefits and social costs on children. Despite a growing literature, the circumstances under which children benefit or suffer from parental out-migration are not well understood. The present study examined how the relationship between parental out-migration and children’s education varies across migration streams (internal vs. international) and across 2 societies. Data are from the Mexican Family Life Survey (N = 5,719) and the Indonesian Family Life Survey (N = 2,938). The results showed that children left behind by international migrant parents are worse off in educational attainment than those living with both parents. Internal migration of parents plays a negative role in some cases, though often to a lesser degree than international migration. In addition, how the overall relationship between parental migration and education balances out varies by context: It is negative in Mexico but generally small in Indonesia.
