«Un redondel con muchas cosas dentro». Eso es un conjunto

Resumen

Se examina la comprensión infantil de algunas nociones de la teoría de conjuntos en una muestra de sesenta niños madrileños entre 6 y 11 años de edad. El análisis se centra en la definición y reconocimiento de conjuntos por parte de los niños, la formación de conjuntos a partir de un material dado y la conciencia de la utilidad de los conjuntos y su relación con otras áreas de las Matemáticas. Los resultados indican que más del 50% de los sujetos identifica el conjunto con el diagrama que lo representa y son incapaces de aplicar esas nociones a problemas concretos. Se interpretan estas dificultades a la luz de la descripción piagetiana de los dos tipos de abstracción—empírica y reflexiva—, y los dos tipos de conocimiento—físico y lógico-matemático—a que dan lugar.     

Types of aggressive victims in bullying situations at secondary school / Tipos de víctimas agresivas en situaciones de bullying en Educación Secundaria

Abstract

The distinction between subtypes of passive and aggressive victims in studies of bullying has been a cornerstone of research in recent decades. However, some aspects of victimization still need further elaboration, such as the differentiation of subtypes of aggressive victims of bullying, the dynamics of the process of victimization, and the perceptions that participants have of their victimized classmates. The objective of this qualitative research is to distinguish between different types of aggressive victims, taking account of the testimonies of secondary school students. Focus groups and in-depth interviews have been conducted with 72 adolescents from the second, third and fourth years of Compulsory Secondary Education and the information has been analysed following the steps proposed by Grounded Theory; a systematic methodology involving the discovery of theory through the analysis of data. The results identify six types of aggressive victims: due to the accumulation of stress, provocative victims, victims through contagion, passive telltale victims, academically gifted victims protected by teachers, and finally, displaced aggression victims.     

Clase social y situación dentro de la fratria: Interacción y efectos sobre el desarrollo del individuo

Resumen

En este estudio se analiza la influencia de la clase social, el número de hermanos y el orden de nacimiento sobre una serie de variables cognitivas y de rendimiento escolar.

Se ha realizado la investigación sobre una muestra de 507 alumnos de 1° de E.G.B., pertenecientes a los Centros Públicos de Valladolid y provincia. Las variables de rendimiento escolar se evaluaron a través de la opinión del profesor. La valoración, en cambio, de las cognitivas se realizó por medio de pruebas estandarizadas. Dentro de los efectos principales, y dejando aparte las diferencias marcadas por el medio social, obviamente esperadas, destacamos una fuerte influencia del orden de nacimiento sobre prácticamente todas las variables dependientes. Su interacción con la variable socio cultural es el resultado más destacable del presente trabajo. Dedujimos como hipótesis explicativa las diferentes pautas culturales que propician o no la estabilidad de los patrones educativos familiares.     

Variables involved in personal, social and school adjustment in a sample of preschool-aged children from different cultural backgrounds

The continuing incorporation of immigrant populations into the Spanish educational system poses an important challenge in that all participants must cooperate toward creating the best possible adaptation process at the academic level as well as on the personal and social levels. A number of different factors appear to influence children’s adjustment during the preschool stage, and these factors are especially relevant since many studies have shown that this is a key period for the prevention of future difficulties. The present study examines the variables involved in the adaptation of a group of preschool-aged children from different cultural backgrounds in Spain. The results indicate that preschoolers, regardless of their background, have similar performance and learning potential, with language proficiency being the factor that most clearly affects the other variables investigated. It was also found that children’s attitudes toward learning were related to the presence of behavioral difficulties and with the quality and type of parental child-rearing practices. These practices appear to be related to a number of difficulties immigrant children may experience on personal and social levels.     

Learning styles and approaches to learning in excellent and average first-year university students

We assessed the learning approaches and learning styles of a sample of 148 excellent students selected from 11 degrees from nine centers of the Polytechnic University of Valencia (Spain), and we compared the results with those of a sample of 133 average students from the same centers. We found that excellent students took deeper approach than average students and that they preferred reflective and theoretical learning styles. Average students adopted a more surface approach, and they preferred active and pragmatic learning styles. Greater academic achievement was related to the deep approach and to the reflective and theoretical learning styles. Poorer academic achievement was related to the surface approach and an active style. University professors may reinforce the deep approach by placing high aims for students which go well beyond reproducing knowledge but use other complementary methods other than expository teaching: problem solving, case studies, designing projects, raising questions, discussion and negotiation in the classroom, etc. To accomplish this, teachers must encourage students to be committed, and these methods help do that. It also helps to introduce more demanding evaluation procedures which do not merely involve repeating what has been learnt, but include training guidance that offers students feedback.     

Comparative study of the evaluation of professional competencies by experienced and trainee Spanish primary teachers

Taking as reference the proposals of the European Higher Education Area, the aim of this study is to identify the competencies which a wide sample of teachers in Spanish primary schools (6–12 age group) consider to be important for their professional performance and which they use in their everyday teaching, and to what extent their university training prepared them for their practising professional development. To do this, an ad hoc instrument was devised and applied to experienced practising teachers and to teacher trainees who were on teacher training placements during the last semester of their course. The results of the study show that initial teacher training should deal in depth with the competencies related to the organisation and management of teaching–learning, the use of new technologies in the primary classroom, the involvement of the families, education in values, social skills and skills for working in professional groups. Finally, proposals are made for training based on the articulation between theory and practice, to allow the professional competencies mentioned to be developed and used in practice, as well as encouraging close collaboration between teacher trainers and experienced practising teachers.     

Successful secondary school principalship in disadvantaged contexts from a leadership for learning perspective

The paper we present here is part of the International Successful School Principalship Project (ISSPP), which is designed to analyse the characteristic traits of successful leadership in different contexts and countries [Day, C., and K. Leithwood. 2007. Successful School Leadership in Times of Change. Dordrecht: Springer-Kluwer; Day, C., and D. Gurr. 2014. Leading School Successfully. Stories from the Field. London: Routledge]. One subgroup of the Spanish research team participating in the ISSPP at the University of Granada has contributed to the project by carrying out a comparative study of the type of leadership for learning at four secondary schools in disadvantaged contexts. Following ISSPP data collection protocols and using a category system specially designed to analyse the leadership for learning carried out by the four principals, the results show that four secondary schools have principals with a similar traits, dispositions and value systems; however, the secondary schools with the best academic results employed practices and strategies more closely associated with leadership for learning than schools with poorer academic results. The data provided by this study confirm the traits and strategies that the ISSPP has been identifying in successful principals in disadvantaged contexts in various countries. It also serves as a source of reflection and discussion on the type of leadership for learning present in some disadvantaged secondary schools in Spain.     

Understanding of graphs in social science undergraduate students: selection and interpretation of graphs

How do university students understand the graphs that they read in their textbooks? How does their knowledge regarding the content and their statistical training influence this understanding? Does the kind of task demand also influence this understanding? To answer these questions, we asked a group of psychology students and a group of economics students to choose the most suitable graph for presenting the results of different psychological research studies (reports) (selection task) or to explain in words the results of the same reports shown by means of their graphic representations only (interpretation task). The results showed there were very few differences between groups. Most of the students were able to relate textual information to the adequate graph, but also revealed significant shortcomings and mistakes in their understanding of important syntactic aspects of graphs. They also interpreted the graphs correctly but their interpretation had different levels of complexity, which were not always optimal. We also identified significant differences regarding the difficulty of the reports and the kinds of misinterpretations of graphs. The two tasks thus revealed different pictures of students’ skills in reading and interpreting graphs and, consequently, how the characteristics of task demands influence their performance.     

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.
