En totes les investigacions sobre I'evolució ontogenetica del nen es parteix d'una serie de pressuposits que, plantejats d'una manera explícita o no, determinen el seu enfoc i les seves conclusions teoriques. La relació existent entre desenvolupament i aprenentatge n'es un dels mes importants. Aquesta relació pot considerar-se com a unidireccional (a/ el desenvolupament es una condició previa a I'aprenentatge o b/ I'aprenentatge és desenvolupament) o be com a mútua i interdependent

Based on Rijt-Plooij and Plooij’s (1992) research on emergence of regression periods in the first two years of life, the presence of such periods in a group of 18 babies (10 boys and 8 girls, aged between 3 weeks and 14 months) from a Catalonian population was analyzed. The measurements were a questionnaire filled in by the infants’ mothers, a semi-structured weekly tape-recorded interview, and observations in their homes. The procedure and the instruments used in the project follow those proposed by Rijt-Plooij and Plooij. Our results confirm the existence of the regression periods in the first year of children’s life. Inter-coder agreement for trained coders was 78.2% and within-coder agreement was 90.1 %. In the discussion, the possible meaning and relevance of regression periods in order to understand development from a psychobiological and social framework is commented upon

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

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 actividad del 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

La present comunicació té com a objectiu exposar la innovació docent introduïda en les assignatures de “Coneixement del medi natural, social i cultural” i de “Ciències de la naturalesa i la seva didàctica I”, ambdues assignatures troncals dels estudis de mestre en educació infantil i educació primària respectivament. Aquesta experiència pretén ser una primera prova i recollir criteris que ajudin a orientar les assignatures de l’àrea de ciències experimentals del Departament de didàctiques específiques de cara als nous títols de grau que es posaran en marxa properament. És en aquest nou marc dels estudis superiors on la docència centrada en les competències professionals pren un protagonisme important. Fins aquest curs acadèmic, els alumnes de primer dels estudis de mestre d’educació primària i infantil realitzaven i exposaven les seves propostes didàctiques als propis companys i companyes de classe. Durant el curs 2007-08 s’han modificat els treballs pràctics de tal manera que les propostes didàctiques que es treballin en la facultat es duguin a terme en el context de la Fira de la Ciència amb nens i nenes d’infantil i primària d’escoles de la ciutat de Girona. En concret, els estudiants han de preparar i realitzar “tallers de ciència” adreçats a infants i nens/es. La Fira de la Ciència és una de les activitats incloses en el pla anual del Projecte Pol·len a Girona. Aquest és un projecte europeu de promoció de l’educació científica basada en la indagació i l’experimentació. Les professores responsables de les dues assignatures implicades en l’experiència creiem que aquesta afavoreix el desenvolupament de competències professionals, alhora que introdueix elements motivacionals en relacionar els estudis de mestre amb la realitat escolar en un context i àmbit concret: la didàctica de les ciències experimentals

Les biblioteques públiques per a infants a Catalunya: Anàlisi i propostes de millora de la praxis educativa és una recerca que pretén donar a conèixer la realitat actual catalana entorn les biblioteques públiques infantils, tot fent incidència en les potencialitats educatives que presenten les biblioteques infantils i juvenils. En el desenvolupament del treball s’han recollit i analitzat els avantatges i els inconvenients dels diferents models de biblioteca estudiats, i les possibles relacions que s’estableixen entre aquests models i alguns aspectes com l’autonomia dels infants, els tipus de projectes i activitats infantils que desenvolupen o les repercussions dels espais

This report presents an analysis of the data from the first wave of the Longitudinal Study of Australian Children (LSAC) to explore the wellbeing of 5,107 children in the infant cohort of the study and the 4,983 children, aged 4 to 5 years, in the child cohort. Wave 1 of LSAC includes measures of multiple aspects of children’s early development. These developmental measures are summarised in the LSAC Outcome Index, a composite measure which includes an overall index as well as three separate domain scores, tapping physical development, social and emotional functioning, and learning and cognitive development.

Pooled serum samples collected from 8132 residents in 2002/03 and 2004/05 were analyzed to assess human polybrominated diphenyl ether (PBDE) concentrations from specified strata of the Australian population. The strata were defined by age (0−4 years, 5−15 years, < 16 years, 16−30 years, 31−45 years, 46−60 years, and >60 years); region; and gender. For both time periods, infants and older children had substantially higher PBDE concentrations than adults. For samples collected in 2004/05, the mean ± standard deviation ΣPBDE (sum of the homologue groups for the mono-, di-, tri-, tetra-, penta-, hexa-, hepta-, octa-, nona-, and deca-BDEs) concentrations for 0−4 and 5−15 years were 73 ± 7 and 29 ± 7 ng g−1 lipid, respectively, while for all adults >16 years, the mean concentration was lower at 18 ± 5 ng g−1 lipid. A similar trend was observed for the samples collected in 2002/03, with the mean ΣPBDE concentration for children <16 years being 28 ± 8 ng g−1 lipid and for the adults >16 years, 15 ± 5 ng g−1 lipid. No regional or gender specific differences were observed. Measured data were compared with a model that we developed to incorporate the primary known exposure pathways (food, air, dust, breast milk) and clearance (half-life) data. The model was used to predict PBDE concentration trends and indicated that the elevated concentrations in infants were primarily due to maternal transfer and breast milk consumption with inhalation and ingestion of dust making a comparatively lower contribution.

Polyfluoroalkyl chemicals (PFCs) have been used worldwide for more than 50 years in a wide variety of industrial and consumer products. Limited data exist on human exposure to PFCs in the Southern Hemisphere. Human blood serum collected in southeast Queensland, Australia, in 2006−2007 from 2420 donors was pooled according to age (cord blood, 0−0.5, 0.6−1, 1.1−1.5, 1.6−2, 2.1−2.5, 2.6−3, 3.1−3.5, 3.6−4, 4.1−6, 6.1−9, 9.1−12, 12.1−15, 16−30, 31−45, 46−60, and >60 years) and gender and was analyzed for eight PFCs. Across all pools, perfluorooctane sulfonate (PFOS) was detected at the highest mean concentration (15.2 ng/mL) followed by perfluorooctanoate (PFOA, 6.4 ng/mL), perfluorohexane sulfonate (PFHxS, 3.1 ng/mL), perfluorononanoate (PFNA, 0.8 ng/mL), 2-(N-methyl-perfluorooctance sulfonamide) acetate (Me-PFOSA-AcOH, 0.66 ng/mL), and perfluorodecanoate (PFDeA, 0.29 ng/mL). Perfluorooctane sulfonamide was detected in only 24% of the pools, and 2-(N-ethylperfluorooctane sulfonamide) acetate was detected in only one. PFOS concentrations were significantly higher in pools from adult males than from adult females (p = 0.002); no gender differences were apparent in the pools from children (<12 years old). The highest mean concentrations of PFOA, PFHxS, PFNA, PFDeA, and Me-PFOSA-AcOH were found in children <15 years, while PFOS was highest in adults >60 years. Investigation into the sources and exposure pathways in Australia, in particular for children, is necessary as well as continued biomonitoring to determine the potential effects on human concentrations as a result of changes in the PFC manufacturing practices, including the cessation of production of several PFCs.

Background: Polybrominated diphenyl ethers (PBDEs) are used as flame retardants in many products and have been detected in human samples worldwide. Limited data show that concentrations are elevated in young children. Objectives: We investigated the association between PBDEs and age with an emphasis on young children from Australia in 2006–2007. Methods: We collected human blood serum samples (n = 2,420), which we stratified by age and sex and pooled for analysis of PBDEs. Results: The sum of BDE-47, -99, -100, and -153 concentrations (Σ4PBDE) increased from 0–0.5 years (mean ± SD, 14 ± 3.4 ng/g lipid) to peak at 2.6–3 years (51 ± 36 ng/g lipid; p < 0.001) and then decreased until 31–45 years (9.9 ± 1.6 ng/g lipid). We observed no further significant decrease among ages 31–45, 45–60 (p = 0.964), or > 60 years (p = 0.894). The mean Σ4PBDE concentration in cord blood (24 ± 14 ng/g lipid) did not differ significantly from that in adult serum at ages 15–30 (p = 0.198) or 31–45 years (p = 0.140). We found no temporal trend when we compared the present results with Australian PBDE data from 2002–2005. PBDE concentrations were higher in males than in females; however, this difference reached statistical significance only for BDE-153 (p = 0.05). Conclusions: The observed peak concentration at 2.6–3 years of age is later than the period when breast-feeding is typically ceased. This suggests that in addition to the exposure via human milk, young children have higher exposure to these chemicals and/or a lower capacity to eliminate them. Key words: Australia, children, cord blood, human blood serum, PBDEs, polybrominated diphenyl ethers. Environ Health Perspect 117:1461–1465 (2009). doi:10.1289/ehp.0900596

Executive function (EF) emerges in infancy and continues to develop throughout childhood. Executive dysfunction is believed to contribute to learning and attention problems in children at school age. Children born very preterm are more prone to these problems than their full-term peers.
