This study, situated in a multilingual, English-medium educational context, draws on theory from mathematics and language education to capture teachers’ perspectives on the place of language in their mathematics pedagogy. The benchmark study explored this topic through surveying and interviewing teachers. Additionally, it sought to relate teachers’ views to their practice by focusing on observing three teachers’ mathematics lessons at primary one, three, and five. Findings are that mathematics teachers placed importance on teaching language, being specifically concerned with language as input and comprehension. They taught vocabulary and reading skills in supportive ways explicitly yet differently at the three grade levels. Particularly at the lower levels, teachers contextualised language in the concrete examples employed for mathematics teaching. At all three levels, prominence was given to teaching pupils how to read word problems as well as how to solve them. However, at primary three, a tension was observed between the two aims of teaching mathematical vocabulary and teaching the reading skills for word problems. This paper illustrates the tension and discusses its possible causes. 相似文献

This paper describes how a ‘whole-school/community development’ anti-bullying programme was designed, implemented and evaluated in an initiative in Erris, Co. Mayo, Ireland, involving local primary and post-primary schools and community groups. Students from seven participating schools (five primary, two post-primary) completed modified versions of the Olweus Bully/Victim Questionnaire both prior to and following programme implementation. Thereafter, there were reductions in students' reports of involvement in bully/victim problems and increases in their reports of feelings about bullying and countering bullying that were consistent with an anti-bullying ethos. The sizes of these effects were modest, in some cases perhaps due to the significantly low incidence of students' involvement in bully/victim problems prior to the programme. This model is in continued use in Erris, and in its further development it is intended to seek out opportunities to implement and evaluate it in other locations. 相似文献

ABSTRACTWe investigated students’ perceptions related to psychological constructs in their science classes and the influence of these perceptions on their science identification and science career goals. Participants included 575 middle school students from two countries (334 students in the U.S. and 241 students in Iceland). Students completed a self-report questionnaire that included items from several measures. We conducted correlational analyses, confirmatory factor analyses, and structural equation modelling to test our hypotheses. Students’ class perceptions (i.e. empowerment, usefulness, success, interest, and caring) were significantly correlated with their science identification, which was correlated positively with their science career goals. Combining students’ science class perceptions, science identification, and career goals into one model, we documented that the U.S. and Icelandic samples fit the data reasonably well. However, not all of the hypothesised paths were statistically significant. For example, only students’ perceptions of usefulness (for the U.S. and Icelandic students) and success (for the U.S. students only) significantly predicted students’ career goals in the full model. Theoretically, our findings are consistent with results from samples of university engineering students, yet different in some ways. Our results provide evidence for the theoretical relationships between students’ perceptions of science classes and their career goals. 相似文献

This article will focus on an event in the educational history of Wales in the 1980s which still impacts both on school practice and on thinking about concepts of Welsh identity. That event was the creation of the History Committee for Wales which was charged with devising a history curriculum for Welsh schools in the wake of the 1988 Education Act. The story will be told largely by using evidence gleaned in elite interviews with the ministers, senior inspectors and civil servants most closely associated with the decision to support or accept the creation of this committee. The significance of the decision will be assessed by charting the progress of curriculum devolution in Wales from the beginnings of state education and the implications of this for ideas of Welshness. This background will be briefly sketched, as will the background to the 1988 Education Act on a wider canvas. General reaction to that act in the Welsh Office will be discussed before the detailed implications for the subject of history will be explored in detail. It will then be argued that wider discussions as to how schools should approach and reflect the history and culture of nations not only shed important light on devolutionary processes which were gathering pace at the time but also reflect the nature of Welshness as perceived by senior figures in the world of education policy-making. 相似文献

Recent research in science and technology studies changed the way we understand science as it is practiced—that is, how scientific knowledge emerges from social, natural, social, political, cultural, historical, and economic contingencies of scientific work. Many science educators agree that students should learn not only science but also about science. In this article, we (a) outline important findings, research methods, and ways of reporting research that emerged from science and technology studies; and (b) show how familiarity with science and technology studies research can provide science educators with valuable insights about curriculum design and research on learning. We conclude that science and technology studies can serve as a resource to science education and that there is a potential for conducting collaborative work between science education and science and technology studies. Such collaborations have the potential to yield better theories about how people become competent in science from childhood to adulthood. © 1998 John Wiley & Sons, Inc.

Demands for educational accountability are being called for at all levels: preschool through graduate school. Standardized tests are being widely utilized, but this measurement is not appropriate for young children. Portfolio assessment is a more promising approach to measure children's growth, development, and achievement. This paper outlines criteria that portfolios must have in order to be effective assessment tools. Methods of gathering information and tips for portfolio development are shared and several examples of children's work samples are included 相似文献

The paper combines a comprehensive account of the probabilistic model of retrieval with new systematic experiments on TREC Programme material. It presents the model from its foundations through its logical development to cover more aspects of retrieval data and a wider range of system functions. Each step in the argument is matched by comparative retrieval tests, to provide a single coherent account of a major line of research. The experiments demonstrate, for a large test collection, that the probabilistic model is effective and robust, and that it responds appropriately, with major improvements in performance, to key features of retrieval situations.Part 1 covers the foundations and the model development for document collection and relevance data, along with the test apparatus. Part 2 covers the further development and elaboration of the model, with extensive testing, and briefly considers other environment conditions and tasks, model training, concluding with comparisons with other approaches and an overall assessment.Data and results tables for both parts are given in Part 1. Key results are summarised in Part 2. 相似文献

The biotechnology industry is a striking example of the disconnect between the location of knowledge creation and its commercial development. I argue that national technological performance in biotechnology is critically affected by institutions governing scientific careers, which shape the professional identities and boundary-spanning activities of research scientists. I test this in a comparison of the United States and France. Drawing on fieldwork and analysis of patent data, I compare institutional frameworks and estimate models of forward patent citations. The models show that entrepreneurial firms are associated with high-performing innovations in this sector whereas large established firms perform poorly in both countries, and highlight the importance of institutions in creating country-specific combinations of human capital with organizational capabilities. 相似文献
