The early course of language development among children from bilingual homes varies in ways that are not well described and as a result of influences that are not well understood. Here, we describe trajectories of relative change in expressive vocabulary from 22 to 48 months and vocabulary achievement at 48 months in two groups of children from bilingual homes (children with one and children with two native Spanish-speaking parents [ns = 15 and 11]) and in an SES-equivalent group of children from monolingual English homes (n = 31). The two groups from bilingual homes differed in their mean levels of English and Spanish skills, in their developmental trajectories during this period, and in the relation between language use at home and their vocabulary development. Children with two native Spanish-speaking parents showed steepest gains in total vocabulary and were more nearly balanced bilinguals at 48 months. Children with one native Spanish- and one native English-speaking parent showed trajectories of relative decline in Spanish vocabulary. At 48 months, mean levels of English skill among the bilingual children were comparable to monolingual norms, but children with two native Spanish-speaking parents had lower English scores than the SES-equivalent monolingual group. Use of English at home was a significant positive predictor of English vocabulary scores only among children with a native English-speaking parent. These findings argue that efforts to optimize school readiness among children from immigrant families should facilitate their access to native speakers of the community language, and efforts to support heritage language maintenance should include encouraging heritage language use by native speakers in the home.

The unique relation of language use (i.e., output) to language growth was investigated for forty-seven 30-month-old Spanish-English bilingual children (27 girls, 20 boys) whose choices of which language to speak resulted in their levels of English output differing from their levels of English input. English expressive vocabularies and receptive language skills were assessed at 30, 36, and 42 months. Longitudinal multilevel modeling indicated an effect of output on expressive vocabulary growth only. The finding that output specifically benefits the development of expressive language skill has implications for understanding effects of language use on language skill in monolingual and bilingual development, and potentially, for understanding consequences of cultural differences in how much children are expected to talk in conversation with adults.

More community college students are taking out loans than ever before and their median debt levels are increasing. This trend is disconcerting because community college borrowers are overrepresented among loan defaulters and those who dropout without having earned a degree. While not without criticism, a growing number of community colleges are choosing not to participate in the federal student loan programs, citing a desire to protect their students from future financial hardships. This study used data from the Beginning Postsecondary Student (BPS:04/09) survey and propensity score matching techniques to examine the effects of loans on persistence for students enrolled in associate's degree programs. Results indicated that borrowing during the 1st year had a positive effect on persistence at the end of year one, but had a negative effect on persistence measured three and 6 years after initial enrollment. As community college students assess their prospects for degree completion and the return on their financial investment in higher education, we hypothesize that borrowers are more likely to become dissatisfied with their investment decision than non-borrowers and choose to dropout rather than take on additional loan debt. Findings from this study suggest the need to carefully reconsider current policies and practices regarding loan use among community college students.

The robust relation between maternal education and child language that is observed in monolingual populations has not been reliably replicated among bilingual children from immigrant families in the United States. We hypothesized that a variable that operates in immigrant populations-the language in which mothers achieved their highest level of education, is relevant to the benefits of maternal education to children's language growth. The participants were 92 U.S.-born bilingually developing children (47 boys, 45 girls) with native Spanish-speaking immigrant mothers. The mothers varied both in their level of education and in the language (English or Spanish) in which they had achieved their highest level of education. The children's expressive vocabulary in English and Spanish was assessed at 6-month intervals between 30 and 60 months. Four sets of multilevel models, which included estimates of children's relative amount of input in each language and mothers' age of arrival, found that maternal level of education in English was significantly related to children's English skill, but not their Spanish skill, and that maternal level of education in Spanish was related to children's Spanish skill, but not their English skill. These language specific relations between mothers' levels of education and their children's language development potentially explain previous findings in immigrant populations. These findings further argue that maternal education benefits children's language because education changes mothers' use of the language in which that education was achieved. There was no evidence of a language general benefit of education, as might arise from increased knowledge of child development. (PsycINFO Database Record
