An analysis of story comprehension through spoken and written summaries in school-age children

This paper discusses the ability of children in third (about 8-years-old) and fifth (about 10-years-old) grade to produce spoken and written summaries. Two main measurement types were distinguished: micropropositional analysis and story grammar analysis. In micropropositional analysis, the results showed significant differences between both summary conditions (spoken/written); while the spoken condition provided the use of inferences and macrorules, the written condition increased the literal recall (copy-delete). In contrast, in the story grammar analysis, the findings showed that both the structural organization and the type of propositions recall were very similar in both types of summaries. Finally, our results showed that the older children appeared to have some qualitative advantage in the use of the story schema; and the effects of the summary type seemed to be less significant.     

Towards a change in the role of the support teacher in the Spanish education system

This paper presents a research study carried out in Murcia, Spain. The research explores the way support teachers understand their role and how they carry it out. We have analysed certain aspects of the schools studied, the students with special educational needs who attend these schools and the support teachers' training. This information allows us to assess their role and to determine the changes necessary to understand it from the curricular model characteristic of an inclusive school.     

Contexto y procesos cognitivos. La interacción niño-adulto

Resumen

En este trabajo se revisa la incidencia del contexto social en el desarrollo cognitivo del niño. En él se analiza este problema desde diferentes perspectivas teóricas inspiradas en la biología y la etología, y se alude al planteamiento ecológico de Bronfenbrenner. Se presenta especial atención a los trabajos empíricos que, partiendo de la obra de Vygotsky, analizan la relación del niño con el adulto insistiendo en cómo ésta desempeña un importante papel en el paso de la regulación de la propia conducta a partir de los otros a la autorregulación y en cómo facilita al niño, en situaciones de aprendizaje o de solución de problemas, formas adecuadas de codificación o de estructuración de las tareas.     

La autonomía como objetivo de la educación: implicaciones de la teoría de Piaget

RESUMEN

Para Piaget el fin de la educación debe ser el desarrollo de la autonomía, tanto en el terreno moral como en el intelectual. Esto significa desarrollar la capacidad de pensar críticamente por sí mismo. Tanto los valores morales como los conocimientos intelectuales no deben ser interiorizados por los niños, sino construídos desde el interior a través de la interacción con el medio. La educación actual refuerza la heteronomía de los niños y les impide desarrollar su autonomía, que es una tendencia natural en el hombre de base biológica. Algunos principios de enseñanza de una educación que tenga como objetivo el desarrollo de la autonomía son: reducir el poder de adulto del profesor; inducir al niño a intercambiar y coordinar sus puntos de vista con otros niños y con el profesor de igual a igual; incitar a los niños a tener una mentalidad activa y a tener confianza en su propia capacidad de descubrir cosas.     

Intangible resources and technology adoption in manufacturing firms

Our objective in this paper is to analyse the determinants of the use of advanced manufacturing technologies in manufacturing firms. We go beyond more traditional approaches and consider the role of complementarities in technology adoption at two levels. First, we adapt Teece's (1986) framework to study the incentives to use new technology that stem from investments in R&D, human capital and advertising. Second, we analyse whether technology use is conditioned by a system effect that arises from the use of related technologies. We test our hypotheses on a representative sample of manufacturing firms in Spain. Our results fully support the idea that R&D investments increase the likelihood of technology use, but only offer partial support for human capital and advertising investments. Export intensity, being part of a business group and epidemic effects are also important determinants of adoption.     

Contribution of historical Spanish inventions to the knowledge of olive oil industrial heritage

This article presents new research, which has the objective of quantifying the knowledge produced by historical technological innovations in the field of olive oil industrial heritage. It studies inventions related to the mechanical processes of the extraction of olive oil between 1826 and 1966, which are recorded in the Historical Archive of the Spanish Patent and Trademark Office. It uses a new adaptation of the methodology of knowledge management (KM) defined by Nonaka and Takeuchi. We have obtained the knowledge value of each innovation according to the level of technological knowledge registered at the time, while distinguishing between the historical evolution of inventions relating to milling and those relating to pressing. In the first analysis, the results show a recession in the quantitative level of knowledge in the olive oil sector with respect to the technological potential of the time. However, when contrasted with the events relating to industrial heritage at the time, it is possible to account for this technological evolution and prove the validity of the methodology used. The results show that general evolution of the knowledge generated has decreased, particularly in the pressing process, although this is not the case in the milling process.     

“Palabras de la ciencia”: Pedro Castera and Scientific Writing in Mexico’s Fin de Siècle

This essay explores the career of the understudied writer Pedro Castera (1846–1906), who is regarded as one of the first practitioners of science fiction in Mexico. A man of many talents, Castera is one of the most eccentric and eclectic figures in the intellectual life of fin-de-siècle Mexico City. His career took many turns: While during specific periods he devoted himself to writing and participating within the liberal, cosmopolitan culture of Mexico City, he often disappeared from the public eye to devote himself to the development of inventions in the mining industry. The essay discusses the different meanings of ‘invention’ within Castera’s oeuvre, namely poetic and scientific innovation. Setting these two concepts within the domains of literature and scientific writing in the global and local fin de siècle, the essay investigates how Castera’s journalism and fiction (specifically his 1890 novel Querens) are representative of the wider question of scientific development in Mexico and Latin America as a whole during the nineteenth century. Furthermore, it explores the intersections of aesthetics and science during a critical period of modern intellectual history, in which these two areas of knowledge were gradually defining themselves as two distinctive cultures.     

Determinism and Underdetermination in Genetics: Implications for Students’ Engagement in Argumentation and Epistemic Practices

In the last two decades science studies and science education research have shifted from an interest in products (of science or of learning), to an interest in processes and practices. The focus of this paper is on students’ engagement in epistemic practices (Kelly in Teaching scientific inquiry: Recommendations for research and implementation. Sense Publishers, Rotterdam, pp 99–117, 2008), or on their practical epistemologies (Wickman in Sci Educ 88(3):325–344, 2004). In order to support these practices in genetics classrooms we need to take into account domain-specific features of the epistemology of genetics, in particular issues about determinism and underdetermination. I suggest that certain difficulties may be related to the specific nature of causality in genetics, and in particular to the correspondence between a given set of factors and a range of potential effects, rather than a single one. The paper seeks to bring together recent developments in the epistemology of biology and of genetics, on the one hand, with science education approaches about epistemic practices, on the other. The implications of these perspectives for current challenges in learning genetics are examined, focusing on students’ engagement in epistemic practices, as argumentation, understood as using evidence to evaluate knowledge claims. Engaging in argumentation in genetics classrooms is intertwined with practices such as using genetics models to build explanations, or framing genetics issues in their social context. These challenges are illustrated with studies making part of our research program in the USC.
