La formación de conceptos y símbolos en niños pequeños

Resumen

En este articulo el autor analiza el desarrollo conceptual y simbólico y sus relaciones evolutivas a los dieciocho meses De acuerdo con los datos que aporta el autor sobre el desarrollo conceptual temprano, existe un desfase entre el desarrollo simbólico y el conceptual siendo la formación del simbolo un fenómeno evolutivo de aparición posterior. Los datos apoyan la hipotesis de que la formación de conceptos y de símbolos constituyen sistemas estructurales independientes aunque ambos desarrollos tienen implicaciones mutuas. Por una parte, la cognición proporciona lina organización conceptual relativamente sofisticada que será utilizada, aunque sólo en parte, por la temprana simbolización. Por otro lado, la simbolización amplía el espacio sobre el que se aplica la conceptualización extendiéndolo basta el no-aquí y no-ahora.     

Education for sustainable development in early childhood education: a review of the research literature

The aim of the study is to describe and analyse research articles relating to the subject of education for sustainable development (ESD) for early childhood education (ECE), published during the years 1996–2013. This is done by answering three specific questions: (1) How is ESD defined by researchers in ECE? (2) What are the major research inquiries and results? (3) What does the research say about young children acting for change in relation to sustainability? Our analysis identified two different definitions of ESD: first, as a threefold approach to education based on questions concerning education about, in and for the environment; and, second, as an approach to education that includes three interrelated dimensions: economic, social and environmental. Two major research areas are identified in this study. The first area relates to how teachers understand ESD, while the second area focuses on how ESD can be implemented in educational practice. During the period studied, the research has evolved from teaching children facts about the environment and sustainability issues to educating children to act for change. This new approach reveals a more competent child who can think for him- or herself and make well-considered decisions. The decisions are made by investigating and participating in critical discussions about alternative ways of acting for change.     

Development and initial validation of a multidimensional questionnaire on the relationship to work (RWQ)

The paper presents first the theoretical foundations used to develop a pre-experimental version of a questionnaire on relationship to work, and then the four stages of its initial validation leading to an experimental version. These stages included: (1) Defining the dimensions and sub-dimensions of the relationship to work concept; (2) Operationalizing the dimensions and sub-dimensions and creating the items; (3) Verifying the face and content validity and developing the pre-experimental questionnaire; (4) Testing the pre-experimental questionnaire with 550 workers and 538 students, assessing its psychometric properties and elaborating the experimental questionnaire.

     

An education policy paradigm that fails upper secondary school pupils

In this article, we illustrate the creation of the education policy paradigm that constitutes the framework of vocational education and training (VET) programmes, and analyse local school representatives’ perception of VET in upper secondary schools in Sweden. The education policy paradigm, established through three periods of reform during the twentieth century, undervalues VET as being less worthy than general/academic education. This paradigm generates the rhetoric used by interviewed school representatives that encourages school pupils to choose the ‘right’ (academic) programmes in order to foster a specific citizenship competence, even if this competence is not fully compatible with labour market demands. Young people who cannot, or will not, attain the ‘right’ education, and thus the advocated citizenship competence, lose out in a school system where general/academic education and higher education preparatory programmes are consistently prioritised over VET. An educational system that advocates discrimination and suspicion of VET limits career options and restricts entry into the labour market, as well as risk stigmatising pupils undertaking VET; this paradigm is neither justified nor democratic.     

Learning biology and mathematics outdoors: effects and attitudes in a Swedish high school context

This research suggests that learning biology in an outdoor environment has a positive cognitive and affective impact on 13–15-year-old, Swedish high school pupils. Eighty-five pupils in four classes participated in a quasi-experimental design. Half the pupils, taking a biology course in ecology or diversity of life, had several lessons outdoors and the other half were taught indoors. All of the classes, but one, also had mathematics lessons outdoors once a week. Twenty-one pupils were interviewed five months after the course and all were positive towards the new learning environment they had experienced outdoors in biology and/or mathematics. They also valued the higher degree of interaction among the pupils. Other findings from the interviews were that the pupils from the outdoor classes showed a higher degree of long-term knowledge retention. They remembered both activities and contents better than the pupils in the indoor classes. An essay-type question assessing their biological understanding qualitatively according to the Structure of Observed Learning Outcome taxonomy revealed no differences between the groups. The results are discussed in the light of neurocognitive models of long-term memory.     

The moderating role of internal and external resources on the performance effect of multitasking: Evidence from the R&D performance of surgeons

R&D employees frequently must split their limited time between explorative R&D and exploitative operative tasks. This article explores the influence of this multitasking (pursuing both R&D and operations) on employee R&D performance. The article also analyzes how the relationship between multitasking and individual R&D performance interacts with the degree of access to internal and external resources. We hypothesize that multitasking positively affects R&D performance. Furthermore, we assume that the internal resources (funding, facilities, and support) are increasingly relevant when employees combine R&D and operative activities. However, multitasking employees may show less of a need for external resources (access to networks) in comparison to more focused colleagues. The results of a survey of 332 surgeons from 20 academic medical centers in Germany support our hypotheses. We conclude that managers should ensure that their R&D workforce is also involved in daily operations. Output will be optimized if these employees are not only engaged with explorative tasks but are also involved in exploitative activities. However, managers should also ensure that the appropriate organizational support is provided to individuals who attempt to combine exploration and exploitation. Multitasking individuals benefit the most from access to internal resources, whereas external resources are more efficiently allocated to explorative-only employees.     

Privileging and Artifacts: On the Use of Information Technology in Science Education

The aim of this paper is to develop an approach that can be used in addressing the issue of the use of information technology and its importance in human meaning making. By using a combination of Wittgenstein’s work method, a sociocultural perspective on learning, and a sociotechnical perspective on artifacts a specific focus for analyses was discerned: the relation between the use-of-technology in meaning-making on one hand and the circumstances for this meaning-making on the other hand. The conversations of six groups of children, who worked with an assignment, that required that they doubted information they encountered, were video recorded and analyzed. The analyses were done in three interrelated steps. (a) The students use-of-technology in meaning making, (b) the meaning patterns that the students encounter on the web, and (c) students’ intentions and habits. Our findings show that, while the mode of reinforcement of the texts used by the students may have provided little opportunity for doubt or learning how to doubt, the students’ habits and intentions with their work determined the result of the interaction, namely copying information from the web. Taking our point of departure in this empirical illustration we discuss theoretical and methodological questions concerning the understanding of the use of information technology in educational settings.     

Recent trends in European migration policies

This paper describes the composition of the migrant worker population in the countries of Western Europe. It traces developments in government policies regarding control and stabilization of immigration, provision for education and granting of political rights. The current international recession and the freeze on immigration might provide a much-needed breathing space for re-thinking policies that affect the personal, educational and vocational futures of large numbers of human beings.
