The black-white test score gap widens with age?

We re-examine the theoretical concept of a production function for cognitive achievement, and argue that an indirect production function that depends upon the variables that constrain parents' choices is both moretractable from an econometric point of view, and more interesting from an economic point of view than is a direct production function that depends upon a detailed list of direct inputs such as number of books in the household. We estimate flexible econometric models of indirect production functions for two achievement measures from the Woodcock-Johnson Revised battery, using data from two waves of the Child Development Supplement to the PSID. Elasticities of achievement measures with respect to family income and parents' educational levels are positive and significant. Gaps between scores of black and white children narrow or remain constant as children grow older, a result that differs from previous findings in the literature. The elasticities of achievement scores with respect to family income are substantially higher for children of black families, and there are some notable difference in elasticities with respect to parents' educational levels across blacks and whites.

Children in the welfare state. A social investment approach

Children occupy centre-stage in any new welfare equilibrium. Failure to support families may produce either of two undesirable scenarios. We shall see a society without children if motherhood remains incompatible with work. A new family policy needs to recognize that children are a collective asset and that the cost of having children is rising. The double challenge is to eliminate the constraints on having children in the first place, and to ensure that the children we have are ensured optimal opportunities. The simple reason why a new social contract is called for is that fertility and child quality combine both private utility and societal gains. And like no other epoch in the past, the societal gains are mounting all-the-while that families’ ability to produce these social gains is weakening.In the following 1 analyze the twin challenges of fertility and child development. I then examine which kind of policy mix will ensure both the socially desired level of fertility and investment in our children? The task is to identify a Paretian optimum that will maximize efficiency gains and social equity simultaneously.

Government and the distribution of skills

Individuals' life chances in the future will very much depend on how we invest in our children now. An optimal human capital model would combine a high mean with minimal variance of skills. It is well-established that early childhood learning is key to adult success. The impact of social origins on child outcomes remains strong, and the new role of women poses additional challenges to our conventional nurturing approach to child development. This paper focuses on skill development in the early years, examining how we might best combine family inputs and public policy to invest optimally in our future human capital. I emphasize three issues: one, the uneven capacity of parents to invest in children; two, the impact of mothers' employment on child outcomes; and three, the potential benefits of early pre-school programmes. I conclude that mothers' intra-family bargaining power is decisive for family investments and that universal child care is key if our goal is to arrive at a strong mean with minimal variance.

Ideas previas de una población universitaria sobre el desarrollo infantil

El presente estudio analiza las ideas sobre el calendario evolutivo de 1.460 estudiantes que acaban de entrar en la Universidad. Las respuestas dadas a un cuestionario en el que se plantean diversas preguntas sobre la edad en que aparecen determinadas conductas y sobre la edad en que es oportuno interactuar con los niños, son, en términos generales, pesimistas (los estudiantes predicen edades tardías) e inexactas (porcentajes pequeños de aciertos). Se analiza también como las predicciones varían en funcion de determinadas variables (sexo, paternidad, edad, etc.) y en función de los conocimientos adquiridos por los estudiantes tras un año de enseñanza en psicologia evolutiva.

Trajectòries de la psicomotricitat: la vivència corporal com a accés a la pròpia identitat i a la representació mental

The Arts (Music, Arts&Crafts and Drama) as a procedure for learning pre-school content: Grupo Edebé Project

There is nothing as amazing and fascinating as children learning process. Between 0 and 6 years old, a child brain develops in a waythat will never be repeated. At this age, children are eager to discover and they have great potential of active and affective life.Because of this, their learning capacity in this period is incalculable. (Jordan-Decarbo y Nelson, 2002; Wild, 1999).Pre-school Education is a unique and special stage, with self identity, which aims are:attending children as a whole,motivate them to learn,give them an affective and stable environment in which they can grow up and get to be balanced and confident people and inwhich they can relate to others, learn, enjoy and be happy.Arts, Music, Visual Arts and Drama (Gardner, 1994) can provide a framework of special, even unique, personal expression.With the aim of introducing qualitative improvements in the education of children and to ensure their emotional wellbeing, and havingnoticed that teachers had important needs and concerns as regards to diversity in their student groups, we developed a programbased on the detection of needs and concerns explained by professionals in education.This program of Grupo edebé, object of our research, is a multicultural, interdisciplinary and globalizing project the aims of which are:developing children's talent and personality,keeping their imagination and creativity and using these as a learning resource,promoting reasoning, favouring expression and communication,providing children with the tools to manage their emotions,and especially, introducing Arts as a procedure to increase learning.We wanted to start the research by studying the impact (Brice, 2003) that this last point had on the learning of five-year-old childrenschooled in multicultural environments.Therefore, the main goal of the research was the assessment of the implementation of a child education programme attending todiversity in a population of five-year-old children, specifically in the practice of procedures based on the use of Arts (music, arts andcrafts and theatre) as a vehicle or procedure for learning contents in Pre-school stage.Because children emotional welfare was a subject of our concern, and bearing in mind that the affective aspects are of vitalimportance for learning and child development (Parke and Gauvain, 2009), Grupo Edebé has also evaluated the starting, evolving andfinal impact in five-year-old children given that they finish Pre-school education at that age.

Acerca de la unidad de análisis en psicologia del desarrollo

La propuesta de Vygotski de sustituir la unidad de análisis de naturaleza diádica propuesta por Piaget por una unidad de análisis de naturaleza triádica en la que ('alguien' organiza socialmente la actividaddel sujeto con el objeto de conocimiento ha llevado a diversos autores a formular como unidad de análisis ((la actividad semióticamente mediada)). En este articulo discutimos, a partir de la noción de contexto y mediante un ejemplo, la validez de dicha unidad. El ejemplo forma parte de un conjunto de observaciones de un niño de 4 años con su madre en situaciones naturales y en el contexto familiar. En las conclusiones mostramos la adecuación de las propuestas de Vygotski sobre la naturaleza social de la mente humana

Expectativas evolutivas, ideas y creencias sobre la educación infantil de familias y maestros: ¿continuidad o discontinuidad?

La perspectiva ecológica sobre el desarrollo humano (Bronfenbrenner, 1979) pone el acento en la relación entre los diferentes contextos de vida de los niños. En la educación infantil, los contextos de vida mas importantes son la familia y la escuela. En este artículo mostramos los aspectos de continuidad y discontinuidad entre ambos contextos en relación a las ideas de las familias y las educadoras sobre el desarrollo infantil y también a sus creencias y expectativas sobre la educación. Los resultados muestran que existe un acuerdo notable en muchos aspectos entre las familias y las educadoras, si bien también existen aspectos de desacuerdo, principalmente entre las educadoras de parvulario y las familias

Las habilidades motrices básicas en educación primaria: aspectos de su desarrollo = Key motor skills in primary education: developmental aspects

The physical education curriculum stresses the importance of improving students’ key motor skills. This idea agrees with the contributions of research into motor development concerning the important role these skills play in child development. In order to facilitate this improvement is essential to know the different basic aspects of how these key motor skills evolve as well as the essential factors related to the characteristics and conditions of educational practice

Seeds of hope: Assessing the effect of development aid on the reduction of child mortality

The Millennium Declaration (2000) set as one of its targets a substantial reduction in child mortality. This paper studies whether the massive increase in development aid can account for part of the reduction in child mortality observed in developing countries since the year 2000. To do so, we analyze a panel of more than 130 developing countries over the 2000-2008 period. We use the time trend evolution of aid to identify an exogenous source of variation. Total aid has had no statistically significant effect on child mortality. However, a disaggregate analysis identifies certain sectors of aid that have had a significant impact. The effects have been larger in high mortality countries, including Sub-Saharan Africa. Projections based on our estimates strongly support the concern that most countries in that region will miss the Millennium Goals target on child mortality.

The usefulness of phonological information for the acquisition of grammatical structure in child language development

During the process of language development, one of the most important tasks that children must face is that of identifying the grammatical category to which words in their language belong. This is essential in order to be able to form grammatically correct utterances. How do children proceed in order to classify words in their language and assign them to their corresponding grammatical category? The present study investigates the usefulness of phonological information for the categorization of nouns in English, given the fact that it is phonology the first source of information that might be available to prelinguistic infants who lack access to semantic information or complex morphosyntactic information. We analyse four different corpora containing linguistic samples of English speaking mothers addressing their children in order to explore the reliability with which words are represented in mothers’ speech based on several phonological criteria. The results of the analysis confirm the prediction that most of the words to which English learning infants are exposed during the first two years of life can be accounted for in terms of their phonological resemblance
