La segmentación de textos. El comportamiento evolutivo entre cinco y once años

Resumen

Mediante tareas de segmentación de textos, se investiga la evolución infantil en el conocimiento de las unidades gramaticales del castellano. Los datos demuestran dos niveles: I. Segmentación por las unidades ortográficamente correctas (espacios), y II. Segmentación por unidades superiores teniendo en cuenta las relaciones sintácticas. Se argumenta sobre la influencia escolar en la solución de estas tareas.     

Peculiaridades de la lectura táctil del braille. Un estudio empírico

Resumen

Este artículo ofrece una discusión sobre las posibles causas que pueden explicar por qué el desarrollo cognitivo de los ciegos presenta retrasos importantes en el período de las operaciones concretas, mientras que no presenta diferencias respecto a los videntes en tareas de tipo proposicional. Para ello se examinan tres posibles explicaciones: la influencia del modo de escolarización, las características del tacto y la remediación verbal. Se acaba concluyendo que estas dos últimas hipótesis son las que ofrecen una explicación más convincente. Los datos que aquí se aportan pare?en sostener la hipótesis dual sobre la representación de la información en la memoria.     

A psychopedagogical approach to the teaching of a programming language in secondary schools

Abstract

Some of the aspects that characterize the novelty and the difficulties observed in the pupil/computer interaction in the school context are discussed from a psycho-cognitive and a psycho-pedagogical point of view. Special emphasis is put on the need to be particularly sensitive to the problems posed to pupils by the introduction of a formal language and by its use for programming and problem-solving.     

Kulturelle Bildung an den Schulen in Deutschland

Previous research findings suggest that school types differ in terms of their extracurricular art-aesthetic offers and that at “Gymnasien” (grammar schools) and “Comprehensive Schools” conditions for art-aesthetic education are particularly favorable. Furthermore, at all-day schools they seem to be more favorable than at other schools. To see whether these findings can be confirmed and differences between school types can be found even after controlling for relevant school characteristics, a nationwide representative survey of school leaders at state schools was analyzed. Three dimensions of art-aesthetic education were examined: extracurricular art-aesthetic offers, cooperation with out-of-school cultural institutions and, finally, school profiles. The results allow for a differentiation and complementation of former findings concerning the specific conditions at different school types regarding the advancement of art-aesthetic experiences, because characteristics such as all-day-school organization, school size or resources were considered.     

Mapping citation patterns of book chapters in the Book Citation Index

In this paper we provide the reader with a visual representation of relationships among the impact of book chapters indexed in the Book Citation Index using information gain values and published by different academic publishers in specific disciplines. The impact of book chapters can be characterized statistically by citations histograms. For instance, we can compute the probability of occurrence of book chapters with a number of citations in different intervals for each academic publisher. We predict the similarity between two citation histograms based on the amount of relative information between such characterizations. We observe that the citation patterns of book chapters follow a Lotkaian distribution. This paper describes the structure of the Book Citation Index using ‘heliocentric clockwise maps’ which allow the reader not only to determine the grade of similarity of a given academic publisher indexed in the Book Citation Index with a specific discipline according to their citation distribution, but also to easily observe the general structure of a discipline, identifying the publishers with higher impact and output.

Analysis of the body composition of Paralympic athletes: Comparison of two methods

Body composition is a physiological variable associated with physical activity and, in some cases, is related to athletic performance. Our objectives were to describe the body composition of participants in three distinct Paralympic sports and to compare the values of body density and estimated body fat obtained from the Paralympic athletes on the National Team by air-displacement plethysmography (ADP) and by the anthropometric method (skinfolds (SFs)). The sample consisted of 70 volunteers of both genders. The body composition of the volunteers was evaluated using the ADP in a Bod Pod^® and seven SFs. There were no significant differences between the values obtained by ADP and SF for body fat percentage (p?=?.58) and body density (p?=?.49). Analysis by Bland–Altman plots showed mean differences of 0.56?±?4.94 (?9.12–10.23) and ?0.0017?±?0.0113 (?0.024–0.020) for body fat percentage and body density, respectively. In conclusion, body composition analyses of Paralympic athletes by the ADP and SF methods show similar results, and ADP should be used as the first option when available. When the use of ADP is not possible, estimating body density and fat percentage by SF is a viable alternative for Paralympic athletes when future comparisons will use the same analysis method.     

Urban classroom conflict: Student-teacher perception: Ethnic integrity,solidarity, and resistance

This study compared student-teacher perception of discipline; inquired if it were interpersonal, procedural, or substantive; and examined how ethnicity, achievement, gender, and position influenced practice. Gay's (1981) theory about interethnic group interactions, combined with perceptual disparity and cultural discontinuity, provided the conceptual framework. Data sources were interviews, classroom observations, and school records. Students (N=16), African American, Chicano, European American, and Filipino, and teachers (N=9) from an urban high school participated. The data analysis revealed that interpersonal conflicts were more consequential for students of color. Evidence of disparate perceptions among ethnically diverse students and teachers surfaced. The attitudes, beliefs, and values of students and teachers differed and were associated with ethnicity, gender, and level of academic achievement.     

Professional Learning Through Everyday Work: How Finance Professionals Self-Regulate Their Learning

Professional learning is a critical component of ongoing improvement and innovation and the adoption of new practices in the workplace. Professional learning is often achieved through learning embedded in everyday work tasks. However, little is known about how professionals self-regulate their learning through regular work activities. This paper explores how professionals in the finance sector (n-30) self-regulate their learning through day-to-day work. Analysis focuses on three sub-processes of self-regulated learning that have been identified as significant predictors of good self-regulated learning at work. A key characteristic of good self-regulation is viewing learning as a form of long-term, personalised self-improvement. This studyprovides a foundation for future policy and planning in organisations aiming to encourage self-regulated learning.     

Influence of source credibility on students’ noticing and assessing comprehension obstacles in science texts

This study aims to analyse the effect of source credibility on students’ identification and assessment of comprehension obstacles in science texts. Source credibility was manipulated by providing 12th grade students with paragraphs supposedly taken from science textbooks or, alternatively, from students’ reports. The paragraphs contained information expected to be difficult to understand by the participating students. The students were instructed to report any comprehension obstacle they might find and to rate the comprehensibility of the paragraphs. There was no effect of source credibility on noticing and reporting comprehension obstacles in the conditions of our experiments. However, there was a significant finding regarding comprehensibility scores. The students rated the comprehensibility of the paragraphs supposedly taken from science textbooks higher than the comprehensibility of the same paragraphs supposedly taken from peer reports. The finding has implications on the way students approach the understanding of science texts. An enhancement of students’ feelings of competence in dealing with scientific subject matter would have a beneficial effect on students’ assessment and validation of information in science texts.
