While the factors that influence college minority student attendance have been the subject of recent study, there remain unresolved questions about how different factors influence college attendance decisions of applicants from historically disadvantaged backgrounds. In particular, there is ambiguity about whether blacks are more or less likely to attend than whites and what factors might improve their attendance rates. This study uses two sets of logistic regressions to identify the factors that can promote minority attendance: a set that examines attendance by all high school seniors in the high school class of 1982 and a set that examines attendance by college applicants in this class. Consistent with prior research on student access, three factors are identified that can potentially improve college attendance by minority students: (1) improved academic preparation in elementary and high school; (2) increased aspirations for higher levels of educational attainment; (3) increased levels of financial aid. Public interventions that would improve any of these factors for minority high school students are likely to improve minority participation rates.  相似文献

Interest in the potential benefits of providing tablet computers to students has grown in recent years, both in UK institutions, and across the world. Limited research studies have been reported in higher education (HE), and primary and secondary school settings, tentatively suggesting a range of positive impacts on learners, but little conclusive research has been published on the introduction of tablets in further education (FE). This article presents a case study of a single, mid-size English FE college, which piloted the provision of tablets to bounded groups of students and teachers in four diverse curriculum areas. The author was invited to help design the college’s evaluation of the pilot, which would inform a potential business case to extend the pilot to all students. One element was a qualitative research project, with data captured through a series of focus group interviews with all 64 students who received tablets, and separate interviews with their ten teachers. Findings are reported here, exploring the extent to which students and teachers perceived learning benefits from the tablets: for some learners, this was reported as enhancing the organisation of learning; supporting greater independence of learning and enabling more purposive learning. Barriers to learning enhancement were also identified, including institutional issues (frustration with technical infrastructure), and individual learner disengagement (distraction and surface engagement with mere ‘novelty’). Concluding that the tablets’ clear benefits were not automatically transformative, and engagement was not uniform, findings are relevant to FE managers and leaders of other institutions considering tablets as a possible learning panacea.  相似文献

Culture has featured prominently in minority educational research, policies, and intervention since the early 1960s. It is receiving even more attention today in minority education discourse due to the emergence of cultural diversity and multicultural education as popular national issues. A careful analysis of the new discourse suggests, however, that the issue has shifted from how cultural differences enhance or deter the school adjustment and academic performance of minority children to the problem of cultural hegemony and representation in school curriculum and other domains of education. But cultural diversity and multicultural education are only a partial solution to the problems of culture in minority education. This essay is in two parts. In part one I argue for a reconsideration of the earlier question about how culture affects minority school adjustment and academic performance. I also proposecultural frame of reference as a new level of analysis of the cultural problems that confront minority students at school. In part two I illustrate my points with two case studies from Minority Education Project in Oakland, California.  相似文献

Increasing evidence indicates that individuals with Intellectual Disabilities (ID) might benefit from phonics‐based reading instruction. However, research and instruction in this field has predominantly focused on sight word reading. Models for complex interventions recommend that feasibility research be conducted prior to conducting randomised studies to assess efficacy of interventions (Thabane et al., 2010). The aim of the current paper is therefore to investigate feasibility questions relating to conducting a full‐scale randomised controlled trial (RCT) evaluation of an online, phonics‐based reading programme (Headsprout? Early Reading; HER) with children with ID. Employing a randomised pre‐test post‐test group design, this study explores and trials important aspects of a RCT evaluation to inform a full‐scale RCT. We also found that HER had a significant effect on reading skills when compared with ‘education as usual’, with large effect sizes on the main outcome measure. This indicates that further, more robust evaluations using HER with children with ID are a worthwhile pursuit.  相似文献

Attitudinal data were collected for a sample of 492 parents and public school children before implementation of a metropolitan desegregation plan and for 2 years after implementation. The variables measured included racial attitudes, feelings out desegregation, and school-related attitudes. There were small but significant changes on 7 of the 11 measures, with most of the changes occurring during the first year. There were race and grade-level differences on some of the variables before desegregation, but race and grade level were generally not related to changes over time.This research has been supported by a grant from the Rockefeller Foundation, Division of Social Sciences.  相似文献

Mental toughness can be conceptualised as a set of attributes that allow people to deal effectively with challenges, stressors and pressure. Recent work has suggested that it may be a valuable construct to consider within educational settings. The current studies explored the associations between mental toughness and educational transitions. Study 1 examined the relationships between mental toughness and concerns about moving to a new school in 105 children aged 12–13 years of age. The results revealed significant relationships between several aspects of mental toughness, but particularly confidence in abilities, and children’s concerns. Study 2 examined the relationships between mental toughness and adjustment to university in 200 undergraduate students at various stages of their course. The results revealed a role for several aspects of mental toughness; commitment, control of life, control of emotion, confidence in abilities and interpersonal confidence. The results are discussed in terms of implications for educational practice. It is suggested that measures of mental toughness could be used to identify individuals who may benefit from additional support during transition to a new school or to university, and that future research should explore the potential benefits of mental toughness training.  相似文献

Recent research on principles of best practice for designing effective multimedia instruction has rarely taken into account students’ alternative conceptions, which are known to strongly influence learning. The goal of this study was to determine how well students of quantum mechanics could learn ‘vicariously’ by watching a student-tutor dialogue based on alternative conceptions. Two video treatments were created to summarize key aspects of quantum tunneling, a fundamental quantum mechanical phenomenon. One video depicted a student-tutor dialogue, incorporating many of the common alternative conceptions on the topic, and resolving inconsistencies in reasoning through discussion. The other presented the same correct physics material in an expository style without alternative conceptions. Second year physics students were randomly assigned to one of the two treatments and were tested before and after watching the video during a lecture. Results show a statistically significant (p < .01) advantage for the learners in the dialogue treatment (d = 0.71). Follow-up interviews of students yielded insight into the affective and cognitive benefits of the dialogue video.  相似文献

The purpose of this article is to report findings from an ethnographic study that focused on the co‐development of science literacy and academic identity formulation within a third‐grade classroom. Our theoretical framework draws from sociocultural theory and studies of scientific literacy. Through analysis of classroom discourse, we identified opportunities afforded students to learn specific scientific knowledge and practices during a series of science investigations. The results of this study suggest that the collective practice of the scientific conversations and activities that took place within this classroom enabled students to engage in the construction of communal science knowledge through multiple textual forms. By examining the ways in which students contributed to the construction of scientific understanding, and then by examining their performances within and across events, we present evidence of the co‐development of students' academic identities and scientific literacy. Students' communication and participation in science during the investigations enabled them to learn the structure of the discipline by identifying and engaging in scientific activities. The intersection of academic identities with the development of scientific literacy provides a basis for considering specific ways to achieve scientific literacy for all students. © 2004 Wiley Periodicals, Inc.

As the costs of certain types of scientific research have escalated and as growth rates in overall national science budgets have declined, so the need for an explicit science policy has grown more urgent. In order to establish priorities between research groups competing for scarce funds, one of the most important pieces of information needed by science policy-makers is an assessment of those groups' recent scientific performance. This paper suggests a method for evaluating that performance.After reviewing the literature on scientific assessment, we argue that, while there are no simple measures of the contributions to scientific knowledge made by scientists, there are a number of ‘partial indicators’ — that is, variables determined partly by the magnitude of the particular contributions, and partly by ‘other factors’. If the partial indicators are to yield reliable results, then the influence of these ‘other factors’ must be minimised. This is the aim of the method of ‘converging partial indicators’ proposed in this paper. We argue that the method overcomes many of the problems encountered in previous work on scientific assessment by incorporating the following elements: (1) the indicators are applied to research groups rather than individual scientists; (2) the indicators based on citations are seen as reflecting the impact, rather than the quality or importance, of the research work; (3) a range of indicators are employed, each of which focusses on different aspects of a group's performance; (4) the indicators are applied to matched groups, comparing ‘like’ with ‘like’ as far as possible; (5) because of the imperfect or partial nature of the indicators, only in those cases where they yield convergent results can it be assumed that the influence of the ‘other factors’ has been kept relatively small (i.e. the matching of the groups has been largely successful), and that the indicators therefore provide a reasonably reliable estimate of the contribution to scientific progress made by different research groups.In an empirical study of four radio astronomy observatories, the method of converging partial indicators is tested, and several of the indicators (publications per researcher, citations per paper, numbers of highly cited papers, and peer evaluation) are found to give fairly consistent results. The results are of relevance to two questions: (a) can basic research be assessed? (b) more specifically, can significant differences in the research performance of radio astronomy centres be identified? We would maintain that the evidence presented in this paper is sufficient to justify a positive answer to both these questions, and hence to show that the method of converging partial indicators can yield information useful to science policy-makers.  相似文献
