Socio-Economic and Cultural Context in the Development of Early Mathematical Competencies
This research presents the findings of a comparative study of mathematical competence among 130 students ( M = 54.08 months; SD = 2.57) from vulnerable school contexts in Chile and the Spanish public school system. The study analyses a set of general and specific domain precursors for which evidence of socioeconomic background exists. Using multivariate regression and discriminant analysis techniques, we calculated similarities and differences be…
Modulation of general and specific cognitive precursors to early mathematical competencies in preschool children
Numerical Estimation and Mathematical Learning Methodology in Preschoolers
One of the means for representing quantities/magnitudes is the mental number line. It is still a nonsolved question as to whether the method of learning mathematics in the early years could improve this type of estimating. A total of 233 students, aged four and five years, who learned mathematics with a new method called Open Algorithm Based on Number or the more traditional Closed Based on Ciphers approach, were evaluated with a reliable estimat…
Algunos factores asociados al desempeño académico en matemáticas y sus proyecciones en la formación docente
El estudio permite identificar elementos a considerar en procesos de formación de profesores de matemáticas de ciclo inicial, a partir de la evidencia y análisis empírico de diversas variables asociadas al logro académico en la disciplina. Se destaca la necesidad de relevar el rol de factores afectivo-actitudinales vinculados al aprendizaje de la matemática, ya que ellos pueden afianzar, bloquear o inhibir su nivel de logro. En base a esta eviden…
Longitudinal study of low and high achievers in early mathematics
Background. Longitudinal studies allow us to identify, which specific maths skills are weak in young children, and whether there is a continuing weakness in these areas throughout their school years.Aims. This 2-year study investigated whether certain socio-demographic variables affect early mathematical competency in children aged 5-7 years.Sample. A randomly selected sample of 127 students (64 female; 63 male) participated. At the start of the …
Positive Behavioral Intervention in Children Who Were Wards of the Court Attending a Mainstream School 1
This report looked at the effects of treatment using contingency contracts and token economy procedures in three children, two 14 yr. and one 8 yr., who were wards of the court and attending a mainstream school. Students presented problems of adaptation to school, such as making constant noises with the mouth, hands, or pencil on the desk; frequently emitted raucous cries in the classroom; destruction of school resource materials; verbal aggressi…

El uso de esquemas figurativos para ayudar a resolver problemas aritméticos
Los alumnos con dificultades de aprendizaje presentan, en ocasiones, déficits en matemáticas, especialmente en el área de resolución de problemas. Parece bien establecido que los niveles de resolución de problemas son significativamente más bajos en los alumnos con dificultades de aprendizaje. Los programas instruccionales diseñados para la mejora del aprendizaje en resolución de problemas aritméticos han establecido la importancia de incorporar …
Relationship of Arithmetic Problem Solving and Reflective—Impulsive Cognitive Styles in Third-Grade Students
Different individuals approach mathematical problems in a variety of ways, with these different approaches also reflected in over-all cognitive styles. This investigation had two purposes, first, to determine whether good and poor arithmetic problem solvers differ substantially in cognitive style, and second, to determine whether the students, after training in techniques of solving arithmetic problems, improve their performance with no significa…
Social Exclusion and Minimum Income Programmes in Spain
This article analyses the ways in which Spanish society is dealing with extreme poverty and social exclusion. Spanish society exhibits a paradoxical combination of widespread precariousness and a limited degree of extreme poverty and exclusion. Social exclusion is still, to a great extent, a remnant of the past rather than a result of recent trends in employment. Some of the social policy actions carried out during the last fifteen years with an …
