The purpose of this study was to analyze student achievement data from the first 3 years of the Memphis Restructuring Initiative (MRI). The MRI represents one of the first efforts by an urban school district to move past traditional top-down versus bottom-up reform debates by providing systemic support for outside-in/inside-out implementation and local co-construction of externally-developed reform designs in schools. Analyses of academic achievement focus on a state-of-the-art measure of value added assessments. At the end of 3 years the reforming schools had produced generally positive gains relative to locally matched control schools. Those results varied somewhat by reform type and by level of poverty in the communities being served. Based on the research methods used and the results, implications for future research and practice in educational reform are discussed.  相似文献

本论文主要就高职高专翻译师资建设的现状及其相应对策进行较为深入地探究。翻译课作为高职高专英语专业的一门重要必修课,然而在教学建设上却相对滞后。而其中,翻译师资被普遍认为是翻译教学的瓶颈。针对高职高专翻译师资建设中存在的一系列问题,笔者提出了相应对策,从而对翻译师资的角色进行综合界定,以符合高职高专翻译教学的特殊性,符合翻译教学效果的最大化。  相似文献

Stated learning objectives for final year projects tend to be fairly generic. As a result, individual students' experience of project work will depend heavily on the attitudes and beliefs of their supervisor. This paper questions the purpose of projects in the computing curriculum and proposes a personal theory of teaching through projects. In deciding whether such a personal theory should emphasize disciplinary specific content or an experiential approach to learning we consider teaching and learning as a process of enculturation. The personal theory of teaching proposed envisages projects as an opportunity for students to engage in realistic activity which allows them to learn something of the nature of the discipline. The student may be thought of as being on a journey, while the supervisor takes the role of a guide pointing out alternatives along the route but allowing students ultimately to find their own way.  相似文献

Abstract

Promoting self-determination has become an important aspect of the educational programs of students with disabilities. There is now a sufficient literature base to support some syntheses that enable researchers to judge their progress in this area to date and to provide direction for future research and practice. For this study, we conducted a literature review of studies that measured or examined global self-determination.  相似文献

The purpose of this study was to compare the effects of peer‐mediated versus teacher‐directed reading intervention on the reading performance of high school sophomores. Participants (n = 57) from the lowest 25th percentile of their sophomore class in reading were assigned randomly to peer‐mediated or teacher‐directed intervention. Fifteen to sixteen 25‐minute intervention sessions over 12 weeks included listening passage preview, retelling, and main idea questioning. Linear regression revealed statistically significant main effects of intervention on maze selection, with both treatment groups outperforming a nonequivalent control group (ES = .69–1.00). There were no statistically significant differences on oral reading fluency or maze selection between the peer‐mediated and teacher‐directed groups. Participating in peer‐mediated intervention and receiving more minutes of instruction were significantly associated with higher performance on the district reading assessment. Implications for allocating resources to tiered intervention in secondary schools are discussed.  相似文献

A study of Norwegian science textbooks for grade 8 indicates an individualistic image of science where individual scientists are discovering truth, through experiment. Scientific rationality is grounded in procedures of inquiry alone and not in debate and argumentation within scientific communities. The communal aspects of science tend to become visible in historical examples where science did not function properly due to prejudices or ignorance. Furthermore, science proper and school science are not differentiated between, and 'scientific knowledge about nature' and 'nature' are one and the same. The discourse identified is well suited to provide students with broad and general knowledge about natural and everyday phenomena. However, it is less suitable for teaching about the scientific enterprise in contemporary society. This is worrying for students' scientific literacy as future adults, as this dimension is essential for understanding the nature of science and for democratic citizenship in socio-scientific issues.  相似文献
