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

Many studies have shown that learning to read in a second language (L2) is similar, in many ways, to learning to read in a first language (L1). Nevertheless, reading development also relies upon oral language proficiency and is greatly influenced by orthographic consistency. This longitudinal study aimed to analyze the role of linguistic predictors (phonological awareness, letter knowledge, pseudoword repetition, morphosyntactic comprehension, lexical knowledge and rapid naming) in reading outcomes (fluency, accuracy and comprehension) in a group of bilingual children (n = 30) reading Italian as an L2, compared to a group of monolingual children (n = 56). We ran a multi-group structural equation model. Our findings showed that rapid automatized naming was a significant predictor of reading speed in both groups. However, the study revealed different patterns of predictors for reading accuracy, predictors for monolinguals being LK, phonological awareness and lexical knowledge, while pseudoword repetition was a predictor for bilinguals. Morphosyntactic comprehension was the most significant predictor of comprehension skills in bilingual children. Implications for clinical and educational settings are discussed. 相似文献

There is currently a growing interest in control of stretching of DNA inside nanoconfined regions due to the possibility to analyze and manipulate single biomolecules for applications such as DNA mapping and barcoding, which are based on stretching the DNA in a linear fashion. In the present work, we couple Finite Element Methods and Monte Carlo simulations in order to study the conformation of DNA molecules confined in nanofluidic channels with neutral and charged walls. We find that the electrostatic forces become more and more important when lowering the ionic strength of the solution. The influence of the nanochannel cross section geometry is also studied by evaluating the DNA elongation in square, rectangular, and triangular channels. We demonstrate that coupling electrostatically interacting walls with a triangular geometry is an efficient way to stretch DNA molecules at the scale of hundreds of nanometers. The paper reports experimental observations of λ-DNA molecules in poly(dimethylsiloxane) nanochannels filled with solutions of different ionic strength. The results are in good agreement with the theoretical predictions, confirming the crucial role of the electrostatic repulsion of the constraining walls on the molecule stretching. 相似文献
