We present, in this article, an investigation about the potential of the relationship between formal and non-formal educational environments. Therefore it is not an empirical research, but an essay on the topic. This paper demonstrates the concept that science education and science outreach can be privileged by actions that are developed by closer relations between formal and non-formal places. Currently, non-formal environments such as museums and science and technology centres are considered potential educational resources within the reach of schools. Educators from museums have conducted studies which demonstrate a predominant model of the utilization of these institutions by teachers, which consists of illustrative visits during the exhibitions, but does not feature a collaborative relationship or partnership between schools and these institutions. In Brazil, the main examples of approaches to collaboration between these places and schools have been taking place through the initiatives of teachers or through projects developed by the educational sector, aiming to broaden the dialogue between their institutions and the school community. Another approach mechanism relates to research and extension projects developed by university researchers, sponsored by state and federal funding agencies. In this case, the universities and university museums appear as new social actors that stand in the way of the schools and the cultural environments, complicating the relationship and, at the same time, bringing new questions to the field of educational research. We believe that the discourse in this paper should bring about further discussions in the initial teacher training courses to contribute to the understanding of practices related to the extension of the field of activity of the school.  相似文献   

Defending Constructivism in Science Education     

Gil-Pérez  Daniel  Guisasola  Jenaro  Moreno  Antonio  Cachapuz  Antonio  Pessoa De Carvalho  Anna M.  Martínez Torregrosa  Joaquín  Salinas  Julia  Valdés  Pablo  González  Eduardo  Gené Duch  Anna  Dumas-Carré  Andrée  Tricárico  Hugo  Gallego  Rómulo 《Science & Education》2002,11(6):557-571

After an impressive development throughout the last two decades, supported by a greatamount of research and innovation, science education seemed to be becoming a newscientific domain. This transformation of Science Education into a specific field of researchand knowledge is usually associated with the establishment of what has been called anemergent consensus about constructivist positions. However, some voices have begunto question these constructivist positions and therefore the idea of an advancementtowards a coherent body of knowledge in the field of science education. The goalof this work is to analyse some of the current criticisms of the so-called constructivistorientations and to study their implications for the development of science education asa coherent body of knowledge.  相似文献   

Teaching and learning about solid waste: aspects of content knowledge     

Heloisa Chalmers Sisla Cinquetti  Luiz Marcelo de Carvalho 《Environmental Education Research》2007,13(5):565-577

This paper investigates aspects of content knowledge related to teaching and learning about solid waste, focusing on the processes of learning and teaching by Elementary School teachers in Brazil, in two modalities of continuing education: courses and school‐based meetings. We analyse elements of teachers' reflections whilst referring to three dimensions of environmental education: knowledge, values (ethic and aesthetic), and political participation. We identify which dimensions are predominant, or absent, and the aspects included and developed in projects elaborated by teachers. The results raise issues we consider important to support teacher education and curriculum programmes and help teachers develop more substantial, critical and effective projects about the subject.  相似文献   

Defining and Communicating What “Intercultural” and “Intercultural Communication” Means to Us     

Lily A. Arasaratnam  Roberto Avant-Mier  Aisha Durham  Lisa Flores  Wendy Leeds-Hurwitz 《Journal of International and Intercultural Communication》2014,7(1):14-37

In order to engage in our larger discussion, we needed to share our definitions, framings, and theorizings of what “intercultural” and “intercultural communication” mean to us and how we inflect these based on our own experiences, identities, and perspectives. Discussants break down how they understand the notion of “intercultural” behind commonly used and circulated terms in our scholarship.  相似文献   

Assessment of the state of conservation of stone artworks after laser cleaning: comparison with conventional cleaning results on a two-decade follow up     

Renzo Salimbeni  Roberto Pini  Salvatore Siano  Giancarlo Calcagno 《Journal of Cultural Heritage》2000,1(4):2215

The utilization of laser light to produce fine and selective cleaning of superficial deposits and encrustation from stones was originally proposed more than 20 years ago by John Asmus who performed pioneering trials of laser cleaning on stone façades in Venice, Cremona and Padua. The opportunity to collect stone samples from these sites allowed us to carry out an original study aimed at evaluating the conservation state of stone surfaces cleaned 10–20 years ago by means of three different techniques: Nd:YAG laser radiation, micron sandblasting and chemical pads. Samples of various stone types, as Istria limestone, Botticino limestone and Nanto sandstone were collected and examined by means of optical and SEM microscopy, FT/IR, and EDAX analyses. The results provided preliminary indications that the state of conservation of stone surfaces previously subjected to laser cleaning is generally better in comparison with those which concurrently underwent mechanical and chemical cleaning.  相似文献

History, Philosophy and Science Teaching: Some Answers to “How?”     

Anna Maria Pessoa De Carvalho  Andréa Infantosi Vannucchi 《Science & Education》2000,9(5):427-448

The study of the history and philosophy of science in school science courses is highly recommended. This paper deals with the methodological aspects derived from research in science education and how they have to be taken into account in order to generate effective classroom activities, so that history and philosophy are not relegated to the status of additional rhetoric of conclusions in an extensive curricula. This is illustrated with the analysis of episodes ___ transcribed from videotape records ___ which took place when such activity was introduced into high school physics classes. This analysis has shown that students, when working in cooperative groups over problematic historical episodes, may come to discuss essential features of science. This not only provides a more realistic view of science, but also enhances cognitive and argumentation skills, besides emphasizing the importance of teachers' guidance.  相似文献   

Despicable Others: Animated Othering as Equipment for Living in the Era of Trump     

Julia Khrebtan-Hörhager  Roberto Avant-Mier 《Journal of Intercultural Communication Research》2017,46(5):441-462

This essay comparatively examines U.S.-Russian and U.S.-Mexican interculturality in the Despicable Me movie franchise. We argue that cultural transformations of the main protagonists – Russian Gru and Mexican El Macho – are politically significant cases of U.S.-Russian and U.S.-Mexican interculturality, reflected and constructed by popular culture in general, and by animated cartoons in particular. Conceptualizing and analyzing animation as “equipment for living,” we demonstrate how these cases serve as epistemological and pedagogical tools of confirming U.S.-dominant ideology, and discursively and visually constructing (Russian and Mexican) Others the way that they are currently understood and treated in (the non-fictional) U.S. society.  相似文献   

Indirect estimation of injected mortar volume in historical walls using the electrical resistivity tomography     

Nasser Abu Zeid  Marco Balducci  Francesco Bartocci  Roberto Regni  Giovanni Santarato 《Journal of Cultural Heritage》2010,11(2):220-227

The electrical resistivity tomography (ERT) represents one of the widely used geophysical techniques for the exploration of the subsurface. In the last few years, this method has been demonstrated to be an efficient reconnaissance tool not only for monitoring degradation status of walls and foundations of historical buildings, but also for imaging the spatial distribution of injected mortar, commonly employed for consolidation purposes. A 3D resistivity tomography survey was carried out on four selected wall portions of the historical church of Montepetriolo, Perugia, Central Italy. The obtained 3D resistivity distribution models before and after grouting provided suggestive images of the internal structure of the studied walls. Moreover, the spatial distribution of the zones being filled with mortar was determined quantitatively by scaling the post- to the preinjection resistivity values. Using a well known correlation between resistivity and porosity, established in the geophysical community, a further step towards a more quantitative assessment was attempted to indirectly determine the unit volumes of the injected mortar The obtained results were satisfactory and in some cases almost similar to the yard data. Furthermore, two flat-jack tests confirmed the local increment of the mechanical resistance of the studied left front (2) and right lateral (3) wall portions.  相似文献
