Measuring the quality of early childhood education: Associations with children's development from a national study with the IMCEIC tool in Colombia.

National-level monitoring of quality of early childhood education (ECE) is key to achieving inclusive and equitable education. Most countries report structural quality while process characteristics are rarely observed at the national level. This study examined the associations between ECE and children's development in a middle-income country using data from a nationally representative sample of public centers serving Colombian children (N = 3163; M = 4.3 years, 50% girls; 42% Mestizo, 16% White, 15% Afro-Colombian, 4% Indigenous, 23% not reported). Descriptive findings evidenced low to moderate quality. Multilevel models showed several positive associations between structural and process quality and child outcomes. Results have implications for the existing literature and highlight the feasibility of quality monitoring in low- and middle-income countries.

Modified Profile of Matrix Metalloproteinase 2 and 9 Production by Human Fallopian Tube Epithelial Cells After Infection In Vitro With Neisseria gonorrhoeae.

Epithelial shedding and scarring of fallopian tube mucosa are the main consequences of sexually transmitted Neisseria gonorrhoeae infection and probably involve an imbalance of host extracellular matrix components and their regulators such as matrix metalloproteinases (MMPs). In the current study, primary human fallopian tube epithelial cells were infected with N. gonorrhoeae, and MMP patterns were examined. Gonococcal infection induced a significant increase in secreted MMP-9 and an accumulation of cytoplasmic MMP-2 over time, but no significant MMP-3 or MMP-8 production was observed. Thus, MMP-9 in particular could play a role in tubal scarring in response to gonococcal infection.

Examining the Link between Math Anxiety and Math Performance in Colombian Students / Examinando la Relación entre la Ansiedad Matemática y el Desempeño Matemático en Estudiantes Colombianos / Examinando a Relação entre a Ansiedade Matemática e o Desempenho Matemático em Estudantes Colombianos

This study examines the link between math anxietyand math performance in a group of Colombian students. A total of 296 students between 8 and 16 years of age took part in this study. Analyses by gender and grade were conducted, while controlling for other types of anxiety (i.e., general and test anxiety). In line with that reported in other countries, a negative correlation was found between performance in mathematics and math anxiety. Importantly, this trend was stronger in girls than in boys. Given the limited number of studies exploring the relationship between math anxiety and math performance in Latin America and, particularly, in Colombia, this study fills an important gap in the literature. The results are particularly relevant in view of the poor performance of Colombian students in mathematics, revealed by the most recent PISA reports.

El presente estudio examina la relación entre la ansiedad matemática y el desempeño matemático, en un grupo de estudiantes colombianos. Un total de 296 estudiantes entre 8 y 16 años de edad participaron en la investigación. Se realizaron análisis por género y grado escolar, controlando por otros tipos de ansiedad (i.e., general y relacionada con exámenes). En línea con lo reportado en otros países, se encontró una correlación negativa entre el desempeño en matemática y la ansiedad matemática. Aún más importante, esta tendencia fue mayor en las niñas que en los niños. Dados los pocos estudios que han explorado la relación entre ansiedad matemática y desempeño matemático en Latinoamérica y, particularmente, en Colombia, este estudio llena un vacío importante. Los resultados son particularmente relevantes a la luz del pobre desempeño de los estudiantes colombianos en matemáticas, revelado recientemente por las pruebas PISA.

Teacher-child relationships and the development of academic and behavioral skills during elementary school: a within- and between-child analysis.

Despite recent growth in research highlighting the potential of teacher-child relationships to promote children's development during the early years of school, questions remain about the importance of these relationships across elementary school. Using data from the NICHD Study of Early Child Care (N = 1,364), this study examines between- and within-child associations between teacher-child relationship quality and children's academic achievement and behavior problems from kindergarten (ages 4-6 years) through 5th grade (ages 9-11 years). Results suggest that increases in teacher-child relationship quality are associated with improvements in teacher-reported academic skills and reductions in behavior problems consistently throughout elementary school. As children progressed from kindergarten through fifth grade, the importance of teacher-child relationship quality is unchanging.

Child care and the development of behavior problems among economically disadvantaged children in middle childhood.

Research examining the longer term influences of child care on children's development has expanded in recent years, but few studies have considered low-income children's experiences in community care arrangements. Using data from the Three-City Study (N=349), the present investigation examines the influences of child care quality, extent and type on low-income children's development of behavior problems during middle childhood (7-11 years old). Higher levels of child care quality were linked to moderate reductions in externalizing behavior problems. High-quality child care was especially protective against the development of behavior problems for boys and African American children. Child care type and the extent of care that children experienced were generally unrelated to behavior problems in middle childhood.

Children's early approaches to learning and academic trajectories through fifth grade.

Children's early approaches to learning (ATL) enhance their adaptation to the demands they experience with the start of formal schooling. The current study uses individual growth modeling to investigate whether children's early ATL, which includes persistence, emotion regulation, and attentiveness, explain individual differences in their academic trajectories during elementary school. Using data from the Early Childhood Longitudinal Study - Kindergarten Cohort (ECLS-K), the present investigation examined the association between ATL at kindergarten entry and trajectories of reading and math achievement across 6 waves of data from kindergarten, 1st, 3rd, and 5th grade (n = 10,666). The current study found a positive link between early ATL and individual trajectories of reading and math performance. Overall, children's early ATL was equally beneficial for children regardless of their race/ethnicity and dimensions of their socioeconomic background. However, links between early ATL and academic trajectories differed by their gender and initial levels of math and reading achievement.

A developmental perspective on full- versus part-day kindergarten and children's academic trajectories through fifth grade.

Children's kindergarten experiences are increasingly taking place in full- versus part-day programs, yet important questions remain about whether there are significant and meaningful benefits to full-day kindergarten. Using the Early Childhood Longitudinal Study's Kindergarten Cohort (N= 13,776), this study takes a developmental approach to examining associations between kindergarten program type and academic trajectories from kindergarten (ages 4-6 years) through 5th grade (ages 9-12 years). Full-day kindergarten was associated with greater growth of reading and math skills from fall until spring of kindergarten. Initial academic benefits diminished soon after kindergarten. The fade-out of the full-day advantage is in part explained by differences in the children who attend part- and full-day kindergarten as well as school characteristics.

El vínculo de apego entre hermanos. Un estudio exploratorio con niños Colombianos de estrato bajo / The attachment relation among siblings. An exploring study with low-strata Colombian children

Uno de los aspectos que han permitido casi completamente al margen de la investigación empírica en el área del desarrollo emocional, a pesar de su relevancia teórica, es la posibilidad de establecer vínculos de apego con figuras diferentes a la madre o al principal cuidador. En Colombia la ausencia de investigación sobre este tema se enmarca en un contexto en el que dadas las condiciones sociales y económicas, personas diferentes a los padres son quienes con frecuencias deben sumir el cuidado de los niños. Este es el marco dentro del cual se inscribe el presente estudio que estuvo dirigido a explorara el vínculo de apego entre hermanos que se forma en los niños bogotanos de estratos bajos. Específicamente, se evaluó el potencial del hermano mayor para actuar como figura de apego subsidiaria durantes las ausencias situacionales de la madre. En el estudio se incluyeron 20 parejas de hermanos que fueron observados interactuando en sus casas por espacio de una hora y media. El vínculo de apego entre los hermanos fue evaluado a través del Q-Sort de Apogeo. Los puntajes de las dimensiones evaluadas con el Q-Sort (Seguridad y dependencia), respaldan la hipótesis de que existe un vínculo de apego entre hermanos El hermano mayor actúa como figura del apego subsidiaria y como tal, se constituye en una fuente de seguridad y una base segura desde el cual el hermano menor puede explorara el ambiente.
