Aprender a leer y escribir implica, como sostiene la autora, mucho más que la simple traducción del habla al papel y viceversa. Todo un universo de cambios y posibilidades se abre, desde sus inicios, ante el sujeto que se alfabetiza. Se expone aquí cuáles son esos cambios, agrupados en tres grandes aspectos, y se defiende su presencia conjunta desde los primeros pasos de la enseñanza de la lectoescritura. 相似文献

ResumenSólo los seres humanos utilizan herramientas para dejar trazas permanentes de sus actos comunicativos. Esta capacidad notacional se manifiesta en distintos sistemas notacionales: dibujo, escritura o notación numérica que se distinguen entre sí por sus elementos, por sus regularidades combinatorias y por cumplir distintas funciones. En este trabajo exploramos cómo comprenden los niños entre 3:8 y 6:6 años de edad las relaciones entre sistemas utilizando dos situaciones de producción de notaciones. En la primera los niños debían escribir qué y cuántos objetos aparecen dibujados en una serie de tarjetas. El objeto de esta situación fue verificar sus posibilidades de producir notaciones diferenciadas según las restricciones formales y adecuadas a las funciones específicas de cada sistema. En la segunda, los niños debían inventar letras, números y palabras que no existen. El propósito fue averiguar en qué medida las restricciones formales y la adecuación funcional que hubieran demostrado en la primera situación estaban implícitas en sus procedimientos de producción o podían ser internamente explicitadas, y por tanto transgredidas. Los resultados demuestran que desde muy temprana edad los niños producen notaciones diferenciadas según las restricciones formales propias de la escritura y del sistema de notación numérico. Sin embargo, la diferenciación formal no asegura el uso adecuado de las notaciones para sus funciones específicas. A pesar del conocimiento de las restricciones formales de cada sistema, algunos niños recurren al dibujo para indicar qué objetos hay en una figura o a la escritura para indicar cuántos objetos hay. Sólo cuando el conocimiento de las restricciones formales que estaba implícito en los procedimientos de producción se explicita internamente, y puede por tanto ser transgredido, el niño utiliza cada sistema según su función específica. 相似文献

AbstractThere is a paucity of dietary data in football referees. In this study, 23 elite main and assistant referees (34.4 ± 5.6 years) completed a 7-day dietary record during the competitive season. No nutritional intake differences were observed between main and assistant referees. Referees’ mean daily energy intake (DEI) was 2819 ± 279 kcal. The intake of proteins (1.7 ± 0.2 g · kg?1), carbohydrates (4.1 ± 0.8 g · kg?1) and fats (1.4 ± 0.2 g · kg?1) represented, respectively, 18.4 ± 1.5%, 44.4 ± 4.4% and 34.6 ± 4.1% of the DEI. Carbohydrate intakes before, during and after exercise were 66 ± 42, 7 ± 15 and 120 ± 62 g. Daily carbohydrate, fibre, polyunsaturated fat and water intakes were below recommendations, while fat, saturated fat, cholesterol and sodium intakes were above recommended values. The prevalence of inadequate intake was high for vitamin E (96%), folate (74%), vitamin A (61%), vitamin C (39%), magnesium (26%) and calcium (22%). Carbohydrate intake before, during and after exercise were far from achieving the minimum recommended values. Most referees demonstrated a negligent behaviour of hydration during exercise. Referees would benefit from dietary education in order to optimise performance and health. 相似文献

An activity involving analysis of art in biology courses was designed with the goals of piquing undergraduates’ curiosity, broadening the ways in which college students meaningfully engage with course content and concepts, and developing aspects of students’ higher-level thinking skills, such as analysis, synthesis, and evaluation. To meet these learning outcomes, the activity had three key components: preparatory readings, firsthand visual analysis of art during a visit to an art museum, and communication of the analysis. Following a presentation on the methodology of visual analysis, students worked in small groups to examine through the disciplinary lens of biology a selection of approximately 12 original artworks related in some manner to love. The groups then developed and presented for class members a mini-exhibition of several pieces addressing one of two questions: 1) whether portrayals of love in art align with the growing understanding of the biology of love or 2) whether the bodily experience of love is universal or, alternatively, is culturally influenced, as is the experience of depression. Evaluation of quantitative and qualitative assessment data revealed that the assignment engaged students, supported development of higher-level thinking skills, and prompted meaningful engagement with course material. 相似文献

Preschoolers?? metalinguistic and visual capabilities may be associated with the writing system of their culture. We examined patterns of performance in phonological awareness, naming of letters, morphological awareness, and visual-spatial relations, in 5-year-old native speakers of Spanish (n?=?43), Hebrew (n?=?40), and Cantonese (n?=?63) and the relations of these literacy related skills to concurrent word writing and word reading. The writing systems in these languages represent three major categories, i.e., alphabetic (Spanish), abjad (Hebrew), and morphosyllabic (Chinese). Phonological awareness, letter naming, and perception of visual-spatial relations differed across groups, whereas morphological awareness showed a similar level of attainment in all three languages. Stepwise regression analyses explaining writing and reading for each language separately revealed both commonalities and differences between languages. Phonological awareness assessed by initial syllable deletion contributed to writing and to reading in Cantonese and in Spanish. Phonological awareness assessed by final phoneme isolation explained reading in Hebrew, whereas final and initial phoneme isolation explained writing in Hebrew. Letter naming predicted both writing and reading in Spanish and in Hebrew, while perception of visual-spatial relations did so in Cantonese. At age 5, children??s metalinguistic knowledge and visual discrimination abilities are already attuned to the particular features of the writing system to which they are exposed. 相似文献

AbstractIn this paper, we present a collaboration project within one urban Puerto Rican classroom, focused on constructing a critical literacy inquiry curriculum grounded in the students’ out-of-school literacy practices in their communities, including their experiences with media and popular culture. We focused on a critical literacy and media inquiry unit centered on the students’ self-selected subject of the telenovela. Here, we examine one student’s work to highlight two overarching findings: (1) the visibility of the students’ complex understanding of the media landscapes in telenovelas, particularly the construction of dominant social discourses across telenovela worlds, and (2) the ways that bringing children’s mediatized cultural imaginaries in their creative work supports an approach to literacy in classrooms, where explorations of discourses of power emerge from the students’ knowledge. In order to articulate how children actively examine and construct discourses across multiple social worlds, we examine these findings using the Four Resource Model, and elements of discourse analysis, as theoretical and analytical frameworks, focusing on the construction of identities, worlds and meanings in relation to the social discourses of telenovelas. 相似文献

Background:Few electronic resources are available for new mothers with concerns about changes in their pelvic floor following childbirth. Patients may struggle when seeking authoritative information regarding pelvic floor conditions online given the sensitivity of the topic as well as the inadvertent connection to obscene or demeaning content found online. A health sciences librarian partnered with the Motherhood and Pelvic Health Study, an interdisciplinary research group, to provide expert searching skills for a particularly challenging health condition that patients struggle to find useful information on.Case Presentation:A custom rubric was developed to evaluate existing information products, which included criteria for cultural sensitivity, conflicts of interest, and other red flags. This evaluation process enabled the research team to identify top-tier evidence-based materials that were culturally congruent. This collaborative evaluation process led to the creation of a web-based toolkit resource for new mothers concerned about changes in their pelvic floor. The toolkit connects women to pertinent information on a national health organization''s patient portal, supplemented by videos created by the team to serve as models of communication for women and health care providers.Conclusion:When developing a web-based resource, health sciences libraries can partner with research teams to find, evaluate, and disseminate information. Culturally congruent toolkits such as this one can improve access to health information and lead to improved health outcomes. To ensure that the information highlighted in toolkits is both culturally congruent and authoritative, research teams should form advisory committees and partner with relevant professional medical associations. 相似文献

Standardizing aspects of assessments has long been recognized as a tactic to help make evaluations of examinees fair. It reduces variation in irrelevant aspects of testing procedures that could advantage some examinees and disadvantage others. However, recent attention to making assessment accessible to a more diverse population of students highlights situations in which making tests identical for all examinees can make a testing procedure less fair: Equivalent surface conditions may not provide equivalent evidence about examinees. Although testing accommodations are by now standard practice in most large-scale testing programmes, for the most part these practices lie outside formal educational measurement theory. This article builds on recent research in universal design for learning (UDL), assessment design, and psychometrics to lay out the rationale for inference that is conditional on matching examinees with principled variations of an assessment so as to reduce construct-irrelevant demands. The present focus is assessment for special populations, but it is argued that the principles apply more broadly. 相似文献
