The attitudes of young people arise from an intense interaction with their social groups of reference, and in this work we examine the extent to which this background conditions the individual environmental attitudes of the young. Using data provided by the PISA 2006 survey for the European Union, we test for the influence of the family, the characteristics of the school, and the social interactions or school peer group on attitudes toward the environment. The existence of social interactions, as well as the important role of family characteristics and school activities, are confirmed. The results allow us to emphasize the importance of the social context of the adolescent, and the need to take this into account as a channel that amplifies the influence of specific environmental education strategies.  相似文献

The definitions of ‘negative knowledge’ and the studies in this regard published to date have not considered the categorial distinction Wittgenstein established between knowledge and certainty. Hence, the important role that certainty, despite its omission, should have in these definitions and studies has not yet been shown. In this article, I contrast the term ‘negative certainty’ with that of ‘negative knowledge’ in order to clarify this concept by describing its significant differences with the first. To characterize negative certainty, I base upon two criteria: on the one hand, negative certainty cannot be directly excluded by a positive certainty, and on the other hand, negative certainty must have an obvious and practical usefulness in which its negative nature is clearly appreciated. To illustrate the use of these two criteria, I describe four examples of negative certainty, paying special attention to their educational implications as well as the contrast between negative certainty and negative knowledge.  相似文献

This article presents a study which aimed to explore the professional identity of early childhood teachers in Chile, applying a sociocultural approach. Relying on an exploratory qualitative design, data were collected through focus groups and photo-narratives. The findings show that these teachers understand that child-centred pedagogy is the pillar of their professional identity; that they perceive that this is under threat from the schoolification of early childhood education; and that they admit that their capacity to resist this tendency is limited to the classroom. These findings suggest that, having scarce resources available to negotiate their professional identity in their working context, early childhood teachers in Chile have a limited capacity for agency.  相似文献

This study tested a set of hypotheses derived from the model of academic achievement in mathematics of the Social Cognitive Career Theory in a sample of Argentinean middle school students. To this aim, 277 students (male and female; age: 13–15 years) were assessed using the following instruments: logical–mathematical self-efficacy scale, mathematics outcome expectations, mathematics performance goals, and mathematics ability test. All of these instruments had been adapted for use in Argentinean students. Academic achievement in mathematics (i.e., grades obtained on regular school exams) was the variable to be modeled through the path analysis technique. The analysis allowed identification of interrelations among the variables and identification of direct and indirect effects. Academic achievement in mathematics was partially explained by the model. Overall, the results support the theoretical postulates of Social Cognitive Career Theory.  相似文献

Background: Question‐answering systems (or QA Systems) stand as a new alternative for Information Retrieval Systems. Most users frequently need to retrieve specific information about a factual question to obtain a whole document. Objectives: The study evaluates the efficiency of QA systems as terminological sources for physicians, specialised translators and users in general. It assesses the performance of one open‐domain QA system, START, and one restricted‐domain QA system, MedQA. Method: The study collected two hundred definitional questions (What is…?), either general or specialised, from the health website WebMD. Sources used by the open‐domain QA system, START, and the restricted‐domain QA system, MedQA, were studied to retrieve answers, and later a range of evaluation measures (precision, Mean Reciprocal Rank, Total Reciprocal Rank, First Hit Success) were applied to mark the quality of answers. Results: It was established that both systems are useful in the retrieval of valid definitional healthcare information, with an acceptable degree of coherent and precise responses from both. The answers supplied by MedQA were more reliable that those of START in the sense that they came from specialised clinical or academic sources, most of them showing links to further research articles. Conclusions: Results obtained show the potential of this type of tool in the more general realm of information access, and the retrieval of health information. They may be considered a good, reliable and reasonably precise alternative in alleviating the information overload. Both QA systems can help professionals and users can obtain healthcare information.  相似文献

This study investigates how different stakeholders in Norway experienced a government-initiated, large-scale policy implementation programme on Assessment for Learning (AfL). Data were collected through 58 interviews with stakeholders in charge of the policy; Ministers of Education and members of the Directorate of Education and Training in Norway, and the main actors such as municipality leaders, teachers, school leaders and students. Successful implementation of AfL processes was found in municipalities where there were dialogue and trust between the municipality level, school leaders, teachers and students and where the programme was adapted to the local context. Implementation was challenged when the policy was interpreted as a way of controlling the schools. Despite the successful implementation in some municipalities, the programme did not have any effect upon students’ learning outcome, as measured on national tests in reading and mathematics. The results are discussed in relation to how local assessment cultures with particular characteristics influence governing, accountability and trust.  相似文献

Resumen

El artículo presenta una panorámica de los procesos que han llevado a la relevancia de las investigaciones ecológicas sobre el entorno en la psicología, incluyendo los propios cambios masivos y acelerados sufridos por los entornos evolutivos actuales. Se señalan las características conceptuales y metodológicas de las principales tendencias, corrientes o enfoques en la operacionalización del entorno educativo y los problemas que se plantean de cara a una aplicación social y educativa de las investigaciones psicológicas sobre los entornos del desarrollo. Por último, se bace una propuesta para el desarrollo ulterior en el área.  相似文献

The paper focuses on educational projects developed in the ETSII (Escuela Técnica Superior de Ingenieros Industriales) of the Polytechnic University of Madrid during the past few years. These projects were developed as new tools for enhancing the active role of students, for improving practical teaching, especially by means of virtual laboratories and different sets of problems and exercises, and for promoting self-learning. The paper analyses the use of ICT in teaching, with the case of a developed e-learning platform as a tracking system for subjects. The paper concludes by discussing the new educational trends in the Centre, devoted to develop an active role of students by activities such as peer mentoring and laboratory monitors programs, and competitions for achieving multidisciplinary engineering challenges.  相似文献
