Low-income, inner-city children were involved in a two-year intervention delivered in the regular classroom by regular classroom teachers to develop phonological awareness and word recognition skills. For the treatment children, an 11-week phoneme awareness program in kindergarten was followed by a first grade reading program (extended to grade 2 for some children) that emphasized explicit, systematic instruction in the alphabetic code. Control children participated in the school district's regular basal reading program. Both groups participated in a phonetically-based spelling program mandated by the district. At the end of grade 1, treatment children (n = 66) significantly outperformed control children (n = 62) on measures of phonological awareness, letter name and letter sound knowledge, and three measures of word recognition, and reached marginal significance (0.056) on a fourth. They also significantly outperformed the control children on two measures of spelling. One year later, at the end of grade 2, the treatment children (n = 58) significantly outperformed the control children (n = 48) on all four measures of word recognition. For the groups as a whole, there were no differences on the one measure of spelling readministered at the end of grade 2. However, there were significant differences in spelling between the treatment (n = 16) and control children (n = 13) who remained in the bottom quartile of spellers at the end of grade 2 when partial credit was given for phonetically correct spelling, and significant differences in reading favoring these treatment children on all four measures of word recognition.  相似文献

The use of Computer Algebra Systems (CAS) in years 9 and 10 classrooms as a tool to support learning or in preparation for senior secondary mathematics is controversial. This paper presents an analysis of the positive and negative aspects of using CAS identified in the literature related to these year levels, along with the perceptions of 12 experienced secondary teachers who were working with years 9 and 10 students. The literature review shows that CAS is valued for calculation and manipulation capabilities, the option of alternative representations, the opportunity for systematic exploration and for prompting rich discussion. However, the technical overhead, initial workload for the teacher and unresolved questions about the perceived relative contribution of machine and by-hand work to learning currently pose obstacles to teaching with CAS in the middle secondary years. The teachers who contributed data to this study perceived that using CAS in their teaching is, on balance, worth the effort. However, they believed that CAS is of most benefit to their high ability students and may present an obstacle to their low ability students’ learning of mathematics.  相似文献

It is believed that increasing the X-factor (movement of the shoulders relative to the hips) during the golf swing can increase ball velocity at impact. Increasing the X-factor may also increase the risk of low back pain. The aim of this study was to provide recommendations for the three-dimensional (3D) measurement of the X-factor and lower trunk movement during the golf swing. This three-part validation study involved; (1) developing and validating models and related algorithms (2) comparing 3D data obtained during static positions representative of the golf swing to visual estimates and (3) comparing 3D data obtained during dynamic golf swings to images gained from high-speed video. Of particular interest were issues related to sequence dependency. After models and algorithms were validated, results from parts two and three of the study supported the conclusion that a lateral bending/flexion-extension/axial rotation (ZYX) order of rotation was deemed to be the most suitable Cardanic sequence to use in the assessment of the X-factor and lower trunk movement in the golf swing. The findings of this study have relevance for further research examining the X-factor its relationship to club head speed and lower trunk movement and low back pain in golf.  相似文献

Despite the considerable media time devoted to the teachers’ industrial dispute in England and Wales during 1985‐86 little or no effort was made to represent the conduct of the dispute in particular schools or through the experiences of individual teachers. The impression conveyed was of a uniform type of ‘action’ and similar effects in different schools, although some were reported as being ‘harder hit’ than others, that is more days on strike. In reality, although related to a set of general conditions affecting teachers’ work, the dispute was enacted and experienced very differently in different schools and localities. The conduct of the dispute in particular schools emerged from and was related to a variety of ‘local’ factors. In this paper some of these institutional variations are examined.

The paper consists of two sections. The first attempts to describe and analyse recent structural changes affecting the conditions of work of teaching and thus provide a context for the 1985‐86 industrial action in schools. The second section explores teachers’ interpretations of and involvements in the industrial action in particular schools. The data on which the paper is based were collected as part of a more general research study on school organisation and micro‐politics.  相似文献

ABSTRACT

Although scholarship is important in higher education and faculty productivity expectations are continually increasing, we still do not understand the holistic view of faculty productivity. This study takes a different viewpoint on faculty productivity examining differences by university classification and by discipline. Most importantly, we sought to obtain the effects of the delivery mode of terminal degree on later faculty productivity. The mode of terminal degree via Internet delivery looks attractive to students, but this study found that this has implications for future research productivity. These three elements illustrate a different scope that has important implications for administrative leaders looking to hire future faculty as well as students thinking about becoming a future faculty member. To capture this view, 600 faculty members from 59 American universities were surveyed. From this survey, five different variables emerged to create an overall faculty scholarly productivity factor. This factor was then compared against university classification, discipline, and mode of terminal degree. Results showed surprising significant differences between university classifications and disciplines as compared to scholarly productivity. One of the most noteworthy findings was that there is a significant difference in faculty productivity based on the mode of terminal degree. Furthermore, no difference in later faculty scholarly productivity exists between that of a hybridized, online degree and a purely online degree. Again, these results indicate significant finds which have a high influence on faculty scholarly productivity, which holds important implications for the future of the university.  相似文献

This paper reports on data drawn from a study exploring the educational strategies of 62 Black Caribbean heritage middle-class parents. In this paper, we consider the respective roles of race and class in the shaping of parents’ educational strategies, deploying an analysis that focuses on their intersection and seeks to hold both race and class in productive tension. Drawing on empirical data, we illustrate how parents’ classed and raced identities shape their interactions with school staff.  相似文献

Review     
This essay offers a historical commentary on Turning Points: Preparing Youth for the 21st Century, the 1989 report on middle school education by the Carnegie Council's Task Force on Education of Young Adolescents, The report's opposition to tracking and its advocacy of teacher empowerment, initiatives that have been popular with school reformers of the 1980s, does distinguish Turning Points from earlier proposals for educational change. Most of the report, however, seems to recommend policies that bear a striking similarity to the kind of changes promoted by the advocates of efficiency oriented school reform earlier in the century. The essay examines the historical antecedents for two of these policy recommendations, curriculum integration and school‐based health services. In considering these earlier attempts at reform, this essay identifies flaws that may mitigate the effectiveness of the policies recommended in Turning Points but which the authors of the report fail to mention .  相似文献

This article is based on surveys undertaken for a British Library Research and Innovation Centre/Library and Information Commission‐funded research project. It describes the models of operation of purchasing consortia in two library sectors (health and higher education) and their expenditure patterns. Present and future savings deriving from consortial activity and the effects of consortia on periodicals suppliers are discussed. The article closes by predicting future activity.  相似文献
