When learning a second language does not mean losing the first: bilingual language development in low-income, Spanish-speaking children attending bilingual preschool

This article discusses two investigations which explored the bilingual language development outcomes of comparable groups of low-income, Spanish-speaking, Mexican American children who either did or did not attended a bilingual (Spanish/English) preschool. Study 1 is a replication of a study by Rodríguez, Díaz, Duran, and Espinosa, involving a new sample of 26 children who attended bilingual preschool for one year and 20 control children who remained at home. Study 2 represents a 1-year, longitudinal follow-up of Rodríguez et al.'s, sample of children during and after the children spent another year at home or in the preschool. In both investigations, standardized, objective measures of three components of children's language proficiency (productive language, receptive language, and language complexity) in English and Spanish were obtained at the beginning and end of the academic year. Contrary to fears that have been expressed by some that early exposure to English would lead to children's native language loss, the results of both studies offered no evidence of Spanish proficiency loss for children attending bilingual preschool. Children who attended bilingual preschool, compared to those who remained at home, showed significant and parallel gains in Spanish language development as well as significant and greater increases in English language proficiency over time. Results are discussed in terms of the need for more systematic research to be conducted in this area to inform policy and practice in the early education and development of language-minority children.     

Adaptation of Child Abuse Potential Inventory in Chile: analysis of the difficulties and challenges in the application in Chilean studies

OBJECTIVE: This paper describes two studies aimed at validating the Chilean version of Child Abuse Potential (CAP). The paper also discusses problems in what respects conceptualizing and detecting maltreatment within a process of research as it relates to a specific culture. METHOD: An instrument based on the Child Abuse Potential Inventory was administered to two different samples of 134 people and 280 people, respectively. Both studies are contrasted in terms of internal consistency, factor analysis, and the instrument's ability to discriminate between abusers and non-abusers. RESULTS: Both studies feature good internal consistency (.98 and .95) and a factor structure similar to that of the original instrument; however, the second study shows problems concerning correct subject classification. The contrast of both studies suggests that the instrument is suitable for discriminating between severe child physical abuse and very well-treated children. The indecision area of classification is 67%. CONCLUSION: The results of both studies highlight the need to conceptualize and operationalize child abuse within a specific cultural context. The distinction between abusers and non-abusers becomes more blurred in the less extreme cases.     

Reading and spelling acquisition in European Portuguese: a preliminary study

We investigated the initial development of reading and spelling in European Portuguese. First-graders, tested in February and June, had to read and spell words and pseudowords. In February there were regularity and graphemic complexity effects, indicating that these children relied on grapheme–phoneme conversion. The lexicality effect found in spelling, in June, suggest that by the end of first grade these children had begun to construct an orthographic lexicon. However, lexical addressing is not inconsistent with phonological mediation as regularization errors increased between the sessions. Additionally, the previously reported similarity in global performance of Portuguese and French beginning readers may conceal processing differences that are related to specific characteristics of the corresponding orthographic codes.

Analysis of lexical quality and its relation to writing quality for 4th grade,primary school students in Chile

Few studies have addressed vocabulary quality in developing writing skill in Spanish. Even less addressed it within the Chilean educational system. The specific objective of this study was to characterize, using a comprehensive set of indicators, the quality of the vocabulary produced by Chilean 4th grade students. Based on a national writing survey, a sample of 2056 texts written by 685 students was collected (narrative, persuasive, and informative texts). Current literature defines lexical quality as a composite of diverse factors that, while distinct, are interrelated. To represent the properties of the vocabulary, a set of indicators were selected: (a) lexical diversity; (b) lexical sophistication; and (c) lexical density. Using multilevel modeling (students and schools as levels 1 and 2) to explain a global writing score we found that diversity was a significant determinant for narrative and persuasive texts, density was a significant determinant for the three genres and sophistication was a significant determinant for narrative and expository text. In addition, indicators related to gender and socioeconomic conditions were only significant determinants of narrative stories. The parts of speech most often used also varied according to the purpose of each text. In all genres, words had a short extension and were very sensitive to the input presented in the stimuli. These results imply a significant challenge to this education system: how to promote the development of vocabulary in all children in order to support language learning.     

When differences do not matter: inclusion in a Mexican primary school / Cuando las diferencias no importan: la inclusión en una escuela primaria mexicana

Studies show that disability is a cause of educational exclusion worldwide. Different countries adopt different views of the inclusion movement. Different variables seem to be associated with the success or failure of inclusion. This study takes place in a primary school located in Mexico. It aims to identify how inclusion is experienced by children with and without special needs, and the connections between inclusion and quality of life. Measures utilized were the questionnaire My Primary School from the Index for Inclusion and the Questionnaires on Assessment of Quality of Life for Children, self-report, and parents’ report. Participants are 69 regular students and 15 students with special education needs. Self-reports from regular children and proxy reports from the mothers of the special education needs students were analysed. Results indicated that there is an association between perceived inclusion and experiencing quality of life; having special needs does not impact on scores on QoL or inclusion; educational level does not impact on perceived QoL or inclusion for special education students. These results are discussed in light of a culture that appreciates diversity.     

Distinct Influences of Mothers and Fathers on Kindergartners’ Numeracy Performance: The Role of Math Anxiety,Home Numeracy Practices,and Numeracy Expectations

The current study analyzed maternal and paternal differential influences on numeracy performance in kindergarten children. Participants were 180 Chilean children from backgrounds of low and high socioeconomic status (SES), their mothers, and their fathers. A path analysis was used to explore the influences of both maternal and paternal numeracy practices on children’s numeracy performance and the influences of maternal and paternal expectations and anxiety on those activities. Research Findings: Results showed that mothers and fathers who endorse higher numeracy expectations for their children and who report lower levels of math anxiety also report engaging more frequently in advanced numeracy practices with their children. Mothers’—but not fathers’—engagement in numeracy practices at home predicted children’s numeracy performance. Also, low-SES mothers engaged more frequently in numeracy practices with their children, and mothers in general engaged more often in numeracy activities with girls than with boys. Practice or Policy: These findings improve understanding of how maternal and paternal processes relate differently to numeracy performance in kindergarten children. Moreover, these results highlight the need to take into account parents’ numeracy attitudes and practices, as well as their SES, when designing interventions directed at increasing family support for math achievement.     

The application of production functions to the higher education system — some examples from Portuguese universities

Production functions were established for the Arts and Law Faculties of Coimbra and Lisbon Universities and for the Higher Institute of Engineering of Lisbon, in which the number of enrolled students was related to the number of professors and assistants. It was possible to find in Coimbra and Lisbon Universities the existence of possibilities of substitution among those factors and economies of scale. In the case of the Higher Institute of Engineering there seems to exist a relation of complementarity between the number of professors and assistants. Also with regard to this Institute, a production function for graduates was estimated which relates them to the expenditures on academic staff and materials. It was found that in this case it was necessary to introduce time as a representative of technological progress, although it was found to be negative. These results are discussed, and the interest and the limitations of the use of production functions for educational management purposes are outlined.
