Differential effects of home and preschool learning environments on early language development 下载免费PDF全文

The present study is based on longitudinal data from a German early childhood education and care (ECEC) governmental initiative assessing children's grammatical and vocabulary development between 2;6 and 4;0 years (N = 1,331), quality of the home learning environment and quality of the preschool setting. Results showed that the quality of the home learning environment predicted development in grammatical skills, but not in receptive vocabulary at age 4, while the effects of preschool process quality showed similar relative impacts on both language outcomes. Further analyses revealed effects of accumulated advantages of preschool quality for children from medium‐ and high‐quality home learning environments in their vocabulary development. The results are compared with previous findings from the German ECEC context and discussed with respect to implications for policy efforts to improve ECEC quality and ways in which both learning environments act together on children's development. 相似文献

The Sci-Tec project was based on an interactive, non-deficit model of in-service in which the fundamental principle was to
value the expertise of all participants, and to encourage them to share that expertise with others. As part of the unfolding
of the project, the participants also identified various areas of need as they arose, and these too became elements of the
in-service agenda. The model has proved to be robust when applied in a wide range of schools, and with teachers who originally
expressed widely varying degrees of confidence and interest in teaching primary science and technology.

AbstractSpeech sound disorders are a common communication difficulty in preschool children. Teachers indicate difficulty identifying and supporting these children. The aim of this research was to describe speech and language characteristics of children identified by their parents and/or teachers as having possible communication concerns. 275 Australian 4- to 5-year-old children from 45 preschools whose parents and teachers were concerned about their talking participated in speech-language pathology assessments to examine speech, language, literacy, non-verbal intelligence, oromotor skills and hearing. The majority (71.3%) of children demonstrated lower consonant accuracy than expected for their age, 63.9% did not pass the language-screening task, 65.5% had not been assessed and 72.4% had not received intervention from a speech-language pathologist. The 132 children who were identified with speech sound disorder (phonological impairment) were more likely to be male (62.9%) who were unintelligible to unfamiliar listeners, and had poor emergent literacy and phonological processing skills, despite having typical hearing, oral structures, and intelligence. Children identified by parents and teachers with concerns may have a range of speech, language and communication needs requiring professional support. 相似文献

The One Laptop per Child (OLPC) initiative has been at the forefront of introducing low-cost computers in developing countries. We argue that the problem is not as much as a focus on the provision of affordable technologies, but the lack of consideration of deeply contextualized implementation design and the lack of understanding of psychological mechanisms at the user-level that influence learning impact. A longitudinal quasi-experimental design among nine rural Indian primary schools involved pre- and post- experiment measures conducted with both test (n = 126) and control groups (n = 79). The study objective was to prioritize local contexts during technology implementation design in order to attain educational impact in terms of improved learning outcomes for students. The Contextualized-OLPC education project utilized strategies identified by the Technology-Community-Management model to address contextually germane factors of teacher training, unbiased gender access, and local language use. A second objective was to assess impact of technology introduction while countering extant techno-determinist approaches of impact assessment. We first demonstrated that technological knowledge was associated positively with functional literacy. We situated the experiment in the social cognitive theory to demonstrate that computer self-efficacy mediates the relationship between technological literacy attained as a consequence of the Contextualized-OLPC education project and a specific learning outcome, functional literacy. Overall, the research illustrated that giving primacy to mere deployment of OLPC laptops has limited relevance to children, both in use and outcome. In support, the results demonstrated the role of contextualized technology in rural classrooms alongside an understanding of user psychology that influence learning impact. 相似文献

Elementary school children are often unclear which operations to use when tackling mathematical problems of the open sentence kind (e.g. 3+*=7). We give details of (a) some of their impasse-repair and other problem-solving strategies; (b) computer models of knowledge and misconceptions underlying those strategies; and (c) a CAI program which can identify strategies and remedy gaps in knowledge and misconceptions. Tests of that program with second graders in five schools over six weeks indicate that one third profited significantly. The results are further discussed.1. Jacobijn A. C.

This article explores the effects of the coronavirus disease 2019 (Covid-19) pandemic on the evolution of both physical and digital cadavers within the unique ecosystem of the anatomy laboratory. A physical cadaver is a traditional and established learning tool in anatomy education, whereas a digital cadaver is a relatively recent phenomenon. The Covid-19 pandemic presented a major disturbance and disruption to all levels and types of education, including anatomy education. This article constructs a conceptual metaphor between a typical anatomy laboratory and an ecosystem, and considers the affordances, constraints, and changing roles of physical and digital cadavers within anatomy education through an ecological lens. Adaptation of physical and digital cadavers during the disturbance is analyzed, and the resiliency of digital cadaver technology is recognized. The evolving role of the digital cadaver is considered in terms of increasing accessibility and inclusivity within the anatomy laboratory ecosystem of the future. 相似文献

This case study is based on a research through design project (RTD) that focuses on a technical communication video of the live-action format. It investigates the usability and design-implications of a live-action how-to video, by means of analyzing user-centered data such as YouTube analytics data, usability, and comprehension assessments. In the study, four key live-action video affordances are identified: verifiability, comparability, recordability, and visibility. The identification of these affordances when related to the users’ assessments resulted in several design implementations that would warrant sought-for communication efficacies. Findings show that some assumed efficacies appear to be mitigated by the complexity and the density of the video information. One implication of this is that the implementation of conventional video editing techniques and the addition of on-screen text that serve to make content briefer and more concise into instructional live-action videos requires the technical communicator’s careful consideration. 相似文献

A class of discrete-time nonlinear system and measurement equations having incrementally conic nonlinearities and finite energy disturbances is considered. A linear matrix inequality-based design approach is presented, which guarantees the satisfaction of a variety of performance criteria ranging from simple estimation error boundedness to dissipativity. Some simulation examples are included to illustrate and provide support to the proposed design methodology. 相似文献
