Working memory and planning are fundamental cognitive skills supporting fluid reasoning. We show that 2 games that train working memory and planning skills in school‐aged children promote transfer to 2 different tasks: an attentional test and a fluid reasoning test. We also show long‐term improvement of planning and memory capacities in 8‐year‐old children after playing adaptive computer games specifically tailored to entrain these cognitive functions. Working memory capacity expanded from 5 to 7 items by using our games. Furthermore, steady progression in the task indicates that this capacity can be trained rapidly. Planning abilities persisted in a nonmarkovian form of play, where a move is highly influenced by previous moves, avoiding back‐ups. Here, we introduce a public and growing platform ( http://www.matemarote.com.ar/ ) developed for this research which has the potential for wide use in educational research. 相似文献

Self-assembly is the fundamental but counterintuitive principle that explains how ordered biomolecular complexes form spontaneously in the cell. This study investigated the impact of using two external representations of virus self-assembly, an interactive tangible three-dimensional model and a static two-dimensional image, on student learning about the process of self-assembly in a group exercise. A conceptual analysis of self-assembly into a set of facets was performed to support study design and analysis. Written responses were collected in a pretest/posttest experimental design with 32 Swedish university students. A quantitative analysis of close-ended items indicated that the students improved their scores between pretest and posttest, with no significant difference between the conditions (tangible model/image). A qualitative analysis of an open-ended item indicated students were unfamiliar with self-assembly prior to the study. Students in the tangible model condition used the facets of self-assembly in their open-ended posttest responses more frequently than students in the image condition. In particular, it appears that the dynamic properties of the tangible model may support student understanding of self-assembly in terms of the random and reversible nature of molecular interactions. A tentative difference was observed in response complexity, with more multifaceted responses in the tangible model condition. 相似文献

This paper presents a new approach to science education that takes a path through sociocultural theory and into the ideas of Gloria Anzaldúa. We apply Anzaldúan theory to science education by illustrating it in action through various examples which explore the multidimensionality of teaching science with Latin@ students in various contexts including dual language settings. We present what it is to journey through transformation using examples from educators at various levels of science within the world of teaching science with Latin@ students in the U.S. Our examples illustrate how Latin@ students cross many cultural borders in Spanish, English, Latin@ home culture, school culture, and the world of scientific dialogue and content, and in doing so, go through tensions and transformations between dominant and non-dominant worlds, which should be acknowledged and better understood through Anzaldúan theory. Fundamentally, we present a transformative notion of Latin@ science learning as “living on the bridges” of many dialogic and cultural practices, and having to negotiate these in-between spaces, or “nepantla” (Anzaldu´a and Keating in Interviews, Psychology Press, London, 2000), where Latin@ students must contend with the fragmented and sometimes painful struggle of living in racialized reality amidst the demands of a dominant culture, and where transformation and healing are possible through the path of conocimiento. We advocate for teachers to become science teacher nepantler@s, who guide their students through nepantla, and into a new mestiz@ consciousness of science education. 相似文献

AbstractThe years 1989–91 saw tremendous changes in the political map of Eastern Europe. These changes have resulted in varying degrees of acquisition difficulties for Slavic and Eastern European language collections in Western libraries. The following is an early assessment of the difficulties and the resultant damage done to Slavic collections in the West. Preliminary results show that, on the whole, book receipts are down considerably, prices are up considerably, and inconsistency is the only consistency. The data discussed here were gathered by means of a survey of certain aspects of Slavic1 acquisitions. These data are supplemented throughout by qualitative material gleaned from comments made by vendors and librarians at the 1993 Slavic Librarians' Workshop held at Urbana, Illinois. 相似文献

Contemporary scientific publishing in mathematics and physics (as in other exact sciences) is a complex and rapidly changing process. The most important element of this process, namely, the refereeing process is considered. In particular, meaningful changes towards refereeing process in mathematics and physics are identified and predicted. Considering a transition that takes place from the traditional refereeing system to other models and introducing the four basic parameters of the refereeing process, namely, the review stage, the openness for editors, referees and authors, journals and e-journals, feedback and e-feedback, several different models are proposed and described for improving the traditional refereeing system (e.g., 2-stage open and semi-open pre-review models, 1-stage open and blind pre-review models, and 0-stage open post-review models). 相似文献

In the current media environment the texts available to media audiences are from very diverse sources. This paper deals with a theoretical question of how the audiences' understanding of author co-determines the reader's interpretation of the particular text. Drawing on the tradition of philosophical hermeneutics, a concept of the imagined author is introduced: a result of the text-reader encounter, where the notion of the author suggested by the text is realized by the reader through their prior knowledge and expectations of an author. A multidimensional model of the author is therefore proposed to appreciate different characteristics and values potentially associated by audiences with varying forms of authorial presence. Distinguishing various dimensions of the author allows a matrix of authorial characteristics to be built that positions the author brought into the encounter by the text as a paratextual feature that co-determines the meaning of the text. 相似文献

This essay demonstrates the ways in which some lesbian, gay, bisexual, transgender, or queer (LGBTQ) rights and immigrant rights organizations enact a form of cultural citizenship that relies upon normative belonging with their depiction of LGBTQ and immigrant rights. It also shows how other groups engender what Aimee Carrillo Rowe refers to as “differential belonging,” by directly confronting normative and exclusionary discourses. This paper first justifies linking these two issues by establishing the notion of the “stranger” as a way to describe how both migrants and queers threaten the way the nation state sees itself. It then unpacks both the normative and differential discourses of belonging in relation to two prominent neoliberal values: family values and good citizenship. Finally, this essay considers the implications of differential belonging as a strategy of cultural citizenship that may confront the exclusions that currently constitute the way the US nation-state imagines belonging. 相似文献

This article uses a case study to contribute to the debate on media-political clientelism and its relation to the theory of media systems. It proposes a cross-disciplinary approach between the fields of communication and political sciences and thus analyzes four dimensions to observe the evolution of these practices in the area of television policies during Spanish democracy: license granting, television ownership regulation, politicization of the public service, and partisan news coverage. The period analyzed includes conservative and social democrat governments, trying to find differences in clientelistic practices among the different political parties. The analysis demonstrates how partisan relationships have evolved and what mechanisms have been put in place to maintain clientelistic ties. 相似文献

The author discusses the history and work of the program at the National Széchényi Library to find, document, and collect Hungarica—defined as published in Hungary, written in the Hungarian language, written by a Hungarian author, or written about Hungary or Hungarians—published in Hungary or outside of it. Today both domestically-published and foreign Hungarica are documented in the library's online catalog and in a database of humanities research in Hungarian studies. 相似文献
