ABSTRACTThis study aims to compare word spelling outcomes for French-speaking deaf children with a cochlear implant (CI) with hearing children who matched for age, level of education and gender. A picture written naming task controlling for word frequency, word length, and phoneme-to-grapheme predictability was designed to analyze spelling productions. A generalized linear mixed model on the percentage of correct spelling revealed an effect of participant’s reading abilities, but no effect of hearing status. Word frequency and word length, but not phoneme-to-grapheme predictability, contributed to explaining the spelling variance. Deaf children with a CI made significantly less phonologically plausible errors and more phonologically unacceptable errors when compared to their hearing peers. Age at implantation and speech perception scores were related to deaf children’s errors. A good word spelling level can be achieved by deaf children with a CI, who nonetheless use less efficiently the phoneme-to-grapheme strategy than do hearing children. 相似文献

Research Findings: This study investigated how the Strengthening Families through Early Care and Education initiative in Illinois (SFI) influenced change in 4 child care programs. Findings indicate that SFI influenced quality improvements through 4 primary pathways: (a) Learning Networks, (b) the quality of training, (c) the engagement of program directors, and (e) the organizational climate at programs. SFI's multilevel model of implementation was key to its effectiveness. Two barriers to improving family partnership practices were identified: lack of cultural competence and a negative organizational climate. Practice or Policy: First, quality improvement and professional development efforts are likely to be more effective in promoting real change when they target multiple levels of the context in and around child care programs. SFI's multilevel implementation approach is a model. Second, quality improvement efforts in the area of family engagement may be more effective when specific attention is given to strategies for creating a supportive organizational climate and collegial relationships among staff. Relationships within programs set the tone for relationships with families. Third, cultural competence requires increased attention to efforts to improve the quality of family partnership practices. A focus on organizational cultural competence may provide the workplace environment necessary to support culturally competent practice among program staff. 相似文献

This article looks closely at the talk of two pre-service teachers over time to examine how they used language as a way of rehearsing their evolving agency as literacy educators. Drawing on critical sociocultural theory, I use Agency Tracing to highlight how pre-service teachers’ agentic actions are not isolated phenomena but ones developed and planned with others in language. Through rehearsals, they considered possible options and outcomes of actions before taking risks, therefore bolstering their confidence to act and resist individual and institutional Discourses of literacy. Analysis reveals that because pre-service teachers rehearse agency over time via language, such agency can be developed in teacher education coursework and field experiences. Findings indicate four recommendations to foster agency: rehearsals over time, dissonance to the point of frustration, observations and approximations in field experiences, and interactional spaces for critical reflection. 相似文献

In educational discourse on human learning (i.e. the result of experience) and development (i.e. the result of maturation), there are three fundamental theoretical frameworks, – behaviourism, cognitivism and constructivism, each of which have been applied, with varying degrees of success, in online environments. An ecological framework of human learning and development in interactive learning environments is proposed. Such an inclusive paradigm organizes the fundamental theoretical assumptions of behaviourism (i.e. automated learning), cognitivism (i.e. recall, understanding, analysis, synthesis, evaluation, creativity, problem solving) and constructivism (i.e. private and shared meaning). Based on review of the literature, behaviourism is best conceptualized as a learning theory; constructivist theoretical assumptions are best applied to cognitive development including private online experience (cognitive constructivism) and shared online experience (social constructivism). Cognitivism is a particularly relevant theoretical orientation in understanding both human learning and development in interactive learning environments. 相似文献

Contemporary commentary notes that students are frequently ahead of their teachers in their ability to manipulate and be creative with the internet, digital programs, and mobile technology. In this context it is important to ask, ‘What knowledge do teachers need to teach in the contemporary context where texts are elaborately multimodal, constructed not just of print but of image, sound, and movement?’ This paper proposes some signposts to assist teachers with navigating in this environment. Using teachers’ and researchers’ reflections on practices in a diverse range of settings, both primary and secondary, the analysis explicates the challenges that teachers face in this multimodal context and elucidates some ways they can effectively operate within it. In particular, it argues that it is teachers’ expertise as analysts and critics of texts that needs to guide their planning and teaching in this ‘new’ text world. 相似文献

Conceptualizations of teacher knowledge have shifted to focusing on the role of experiential rather than theoretical knowledge. There are different approaches to this, but the idea of an image that guides practice is widespread. One approach to images that has not been frequently investigated in studies of second language teachers is through sociocultural theory, specifically in the contribution of activity theory known as orienting activity. In this view, images mediate teaching actions by linking theoretical knowledge and practical experience. This article will use orienting activity to examine the role that images play in an English as a second language teacher’s personal practical knowledge by drawing on classroom observations, informal discussions, simulated recall interviews and documentary evidence collected over a nine month period. Analysis of the data shows that several key images mediated the teacher’s classroom actions. These emerged in the observations and in the teacher’s commentary on planned and spontaneous, routine and novel and successful and unsuccessful activities. The images appeared to have developed through both tacit knowledge associated with practical experience and theoretical knowledge associated with research and theory. This demonstrates the usefulness of orienting activity as a theoretical framework for exploring classroom practices and teacher development through the links it can make between theory and practice. 相似文献

This article explores the crucial moments of scientists’ research activities when they decide to shift to a radical new domain or to perpetuate a project. We introduce what we have called the “respiration model” which describes and analyses key cognitive components which occur in this complex process. Respiration either privileges epistemic expectations which are rooted in socio-cognitive metrics of “concentration” or in a functionality-multiple horizon context which we refer to as “extension”. The respiration model accords particular attention to the elements curiosity and synergy in science. 相似文献

The methodology of protecting the European stained glass windows against environmental risk (e.g. meteorological factors, air pollution, microorganisms) by means of an external glazing is not new. In spite of many scientific studies carried out in the last 20 years, some questions were still up for discussion. The European VIDRIO (2002–2005) project gave an answer to these questions. The research carried out by the different project partners established a new multidisciplinary approach aimed at evaluating the efficiency of the protective glazing systems and their effects on stained glass windows conservation, and finally at assessing the most appropriate strategy to preserve stained glass windows. Scientific results showed that the so-called isothermal glazing (i.e. ventilation by the air coming from the inside of the building) protected efficiently the ancient stained glass window from environmental attack (i.e. rain, pollutants, condensation, thermal shocks) with very limited secondary effects. The scientific research highlighted that its efficiency was strongly related to the technical design of the protective system. In particular, the ventilation and the size of the interspace had to be carefully considered. The research developed within the VIDRIO project was turned into general recommendations to the owners and practitioners on the best practice for the stained glass windows future conservation. 相似文献

ABSTRACTPreviously, heavy use of biocides for the treatment of objects made of organic materials in museum collections (e.g. ethnographic, historical collections) was very common. Now suitable decontamination methods/technologies are being sought. A decontamination treatment by li-CO2 was optimized that considered the specific requirements of museum objects. The treatment was tested on model materials artificially contaminated with biocide solutions containing dichlorodiphenyltrichloroethane (DDT), pentachlorophenol (PCP), lindane, and permethrin or cypermethrin. High decontamination was achieved for DDT, lindane, PCP, and permethrin on artificially biocide loaded wool and wood model materials. Optimal process parameter settings for li-CO2 decontamination include a single 30?min cycle for woolen materials and three sequential 30?min cycles each for wood. These methods allow a reduction of at least 90% of all biocides for wool and between 70% and 85% for wood. Decontamination of the latter was more effective for less polar biocides as DDT and permethrin. Despite a significant improvement in decontamination for wood using co-solvents such as acetone, ethanol, and methyl tertiary-butyl ether (MTBE), their use is not recommended due to the increased risk of damage to the objects, in particular if a surface coating is present. 相似文献

ABSTRACT The idea that pornography promotes sexism is a commonly purported one. This study employed an online sample of heterosexual men (N = 323) to investigate the relationship between pornography use (in terms of both overall level of pornography use and use of violent and/or humiliating pornography) and old-fashioned and modern sexism. The moderating effects of agreeableness and perceived realism of pornography were also assessed. Level of general pornography use and use of violent and/or humiliating pornography was not predictive of either sexism measure. Agreeableness was negatively predictive of both sexism measures, whereas perceived realism was positively predictive of sexism. Agreeableness and perceived realism did not moderate the relationship between level of pornography use and any of the outcome measures. 相似文献
