Writing is part and parcel of children's active meaning‐making on and with screens, but it has been relatively neglected in the literature focused on children's digital literacies. This study synthesises existing empirical evidence focused on young children's (aged between 2 and 8 years) writing on screen and identifies the relationships between dominant themes in published literature and contemporary theories of children's technology use. A systematic literature review that included studies from diverse disciplines yielded 21 papers. Constant comparative analysis generated five themes that indicate four key directions for future research. We call attention to researchers' theoretical framing to supplement mono‐disciplinary approaches and single levels of analysis. We suggest that future research should provide greater specification of the purpose of children's writing on screen and the different types of tools and applications supporting the activity. We also highlight the need for interdisciplinary approaches that would capture the composing stages involved in the writing process with and around screens. Finally, we point out possible age‐related differences in documenting and reporting the composing process in classrooms. Overall, limitations in the current evidence base highlight the need for research conducted from a critical perspective and focused more directly on multimodality.  相似文献

To plan group-randomized trials where treatment conditions are assigned to schools, researchers need design parameters that provide information about between-school differences in outcomes as well as the amount of variance that can be explained by covariates at the student (L1) and school (L2) levels. Most previous research has offered these parameters for U.S. samples and for achievement as the outcome. This paper and the online supplementary materials provide design parameters for 81 countries in three broad outcome categories (achievement, affect and motivation, and learning strategies) for domain-general and domain-specific (mathematics, reading, and science) measures. Sociodemographic characteristics were used as covariates. Data from representative samples of 15-year-old students stemmed from five cycles of the Programme for International Student Assessment (PISA; total number of students/schools: 1,905,147/70,098). Between-school differences as well as the amount of variance explained at L1 and L2 varied widely across countries and educational outcomes, demonstrating the limited generalizability of design parameters across these dimensions. The use of the design parameters to plan group-randomized trials is illustrated.  相似文献

Abstract

One major aim of international large-scale assessments (ILSAs) is to monitor changes in student performance over time. To accomplish this task, a set of common items is repeatedly administered in each assessment and linking methods are used to align the results from the different assessments on a common scale. The present article introduces a framework for discussing linking errors in ILSAs, in which different components of linking errors are distinguished (country-by-item interaction, assessment-by-item interaction and country-by-assessment-by-item interaction). Furthermore, the different components of linking errors are used to analytically derive standard errors for national trend estimates. In a simulation study, the proposed standard error formula outperforms the method that is used in PISA. In addition, the PISA 2006 and 2009 reading data are used to illustrate how the interpretation of national trend estimates can change when different procedures are applied to calculate standard errors.  相似文献

This article describes two studies testing the efficacy of a commercial one-on-one cognitive training program (LearningRx) and its computer-based version (Brainskills) in laboratory and school settings. Study 1 tested Brainskills in a laboratory setting with 322 middle school students. Paired t-tests revealed significant gains on all cognitive measures and math performance after 3 weeks of training. Study 2, a randomized control study, included 225 high school students randomly assigned to one of three conditions: LearningRx, Brainskills, or study hall (control) in a school setting for a 15-week training period. Univariate ANCOVAs revealed significantly higher scores for the treatment groups compared with controls on working memory, logic and reasoning, and three of four math attitude measures but not for math performance. Implications for school-based interventions are discussed.  相似文献

Grounded practice and the design of constructivist learning environments   总被引:7,自引:11,他引:7  
A variety of instructional approaches has been studied and implemented across educational and training settings. Vastly different design practices have been proposed that reflect fundamentally different philosophies, beliefs, and biases. Yet, evidence of mismatched frameworks and methods are widespread. This has become particularly problematic in advancing emerging constructivist learning environments. In this paper, we advance the concept of grounded design, a process that involves linking the practices of learning systems design with related theory and research. The purposes of this paper are to introduce the fundamentals of grounded design, to describe how underlying foundations and assumptions can be aligned with the corresponding methods, and to introduce examples of grounded constructivist learning environments.  相似文献

Faced with economic constraints, the governments of Western industrial countries are subjecting higher education to sharper scrutiny, and are looking for new guides to difficult policy choices. In many countries, the expectations of higher education held by specific groups have come to carry greater weight in policy-making as a proxy for analysis of national needs. This article draws on evidence from Austria, Japan, Sweden, the United Kingdom, the United States and West Germany to review the changing expectations of the major groups affected by higher education - the increasingly influential employers of graduates, the consumers of research, young people and their families, new groups such as women and adult students, and others; compares these expectations with broader political interpretations of the needs of the community - for equality, investment and other functions; and describes the responses of government and of institutions of higher education.An earlier version of this article was commissioned by OECD to provide a synthesis of a Conference on Expectations of Higher Education, held at Hatfield Polytechnic in January 1982, organised by the UK Department of Education and Science for an OECD/CERI programme on Innovations in Higher Education. My thanks are due to all the participants in that conference, and especially to the authors of papers, some of whose contributions are quoted extensively in this article.  相似文献

Through 23 open‐ended questionnaires and 8 individual interviews, this phenomenological study explored the experiences of Hispanic men and women (N = 23) who completed doctoral degrees in counselor education. Six themes were identified: family role models, educational support, parental expectations, ethnic identity, acculturation/cultural expectations, and intrinsic motivation.  相似文献

The purpose of this study was to examine relationships between functional movement screen scores, maturation and physical performance in young soccer players. Thirty males (11–16 years) were assessed for maturation, functional movement screen scores and a range of physical performance tests (squat jump, reactive strength index protocol and reactive agility cut). Older players significantly outperformed younger participants in all tests (P < 0.05; effect sizes = 1.25–3.40). Deep overhead squat, in-line lunge, active straight leg raise and rotary stability test were significantly correlated to all performance tests. In-line lunge performance explained the greatest variance in reactive strength index (adjusted R2 = 47%) and reactive agility cut (adjusted R2 = 38%) performance, whilst maturation was the strongest predictor of squat jump performance (adjusted R2 = 46%). This study demonstrated that variation of physical performance in youth soccer players could be explained by a combination of both functional movement screen scores and maturation.  相似文献
