Demographic shifts in recent years have resulted in a smaller proportion of white males in the American population. Historically, we have depended on these individuals to comprise almost all of the science and engineering doctorates for our workforce. America must now develop S&E talent more fully among minority groups and women. Colleges and universities have moved ahead admirably in bringing these individuals into S&E programs and preparing them for doctoral study. Predictably, some have had greater success than others. The present study was completed under a National Science Foundation grant. It sought to identify the more successful institutions and to identify the elements of their success in an effort to effect a sharing of know-how. The National Research Council was asked to rank-order institutions according to their rates of success in sending Indian, Hispanic and black students on to graduate study in science and engineering. Site visits and interviews were made at ten of the top institutions. Using George Kuh's rubric for involving institutions, site visitors identified valuable threads among the practices for talent development among the populations under study.  相似文献

This paper reports the findings of a study investigating the clothing preferences and problems of older women. The sample consisted of thirty women age 65 years and over who were members of two clubs in Tallahassee, Florida. Personal interviews were conducted by the researcher in the home of each respondent.

Style features discovered to be preferred were A‐line skirts; princess, A‐line, and shift dresses; V‐necklines; convertible collars; long with cuff, three‐quarter length, and short sleeve styles. Color preferences revealed blue as the most popular color for clothing. Implications of the research for gerontologists in higher education and for the American clothing industry are cited and discussed.  相似文献

Identifying and understanding predictors of school safety perceptions is important due to its consequences for students. However, it is not clear what school‐related factors most contribute to explaining students’ perception of school safety, and how they relate to community‐related factors such as neighborhood safety. The purpose of this study was to understand the factors associated with Chilean elementary and middle school students’ perceptions of school safety. We used a sample of 5,455 students from low socioeconomic status public schools, and analyzed the predictive value of peer physical and verbal victimization; teacher and school staff victimization; teacher's social support; and perception of safety in the students’ neighborhoods on perceptions of school safety. Findings showed that although different forms of school violence, particularly peer physical victimization and physical and sexual victimization from teachers and school staff, contribute to students’ perception of school safety, the highest contribution came from students perceiving their neighborhoods as unsafe. In contrast, teacher social support contributed to increased levels of perceived school safety. We discuss the need for school‐based interventions that address physical victimization and engage teachers in prosocial and less punitive approaches to foster a positive and safe school climate, and in fostering school–community partnerships.  相似文献

At a time when learning and teaching in higher education have become the focus of increasing attention and high priority is being accorded to the attainment of excellence in teaching there is a growing concern that teaching is being reduced to the acquisition of a set of competencies. This paper will draw on the work of Alasdair MacIntyre to explore the nature of a practice and of teaching as a practice, and then draw on a case study of teachers in a higher education institute in Ireland to gain some insights into the realities of practice. While acknowledging that this knowledge is unequivocally contextual, this case study has the potential to contribute to our understanding of teaching by affording insights into how teachers respond to the challenges of practice. The paper will argue that to conceive of teaching as a practice, in the manner in which practice is explained and elaborated by MacIntyre, moves us beyond a narrow and mechanistic view of teaching built around the adoption of effective strategies to one that is broader in scope and takes into account notions of internal standards of excellence, complexity and integrity.  相似文献

Classroom formative assessment (CFA) is considered to be a fundamental part of effective teaching, as it is presumed to enhance student performance. However, there is only limited empirical evidence to support this notion. In this effect study, a quasi-experiment was conducted to compare 2 conditions. In the treatment condition, 17 teachers implemented a CFA model containing both daily and weekly goal-directed instruction, assessment, and immediate instructional feedback for students who needed additional support. In the control condition, 17 teachers implemented a modification to their usual practice. They assessed their students’ mastery of learning goals on the basis of half-yearly mathematics tests, and prepared weekly pre-teaching sessions for groups of low-achieving students. The posttests showed no significant differences in student performance between the 2 conditions after controlling for student and teacher characteristics. The degree of implementation of the CFA model, however, appeared to be positively related to the 5th-grade students’ performance.  相似文献

Educational methods race to keep pace with the opportunities afforded by technology, and in computer science we need methods that tie together the diverse aspects of the discipline and set them in a realistic human context. Projects have the potential to address various aims and perspectives, and international projects add new dimensions to student teamwork, requiring students to handle collaboration that is remote, cross-cultural, and linguistically challenging. This paper examines some of the educational issues associated with international projects, in the discussion of two examples: PASTICS and Runestone.  相似文献

The authors review research on (a) gay, lesbian, bisexual, and transgender (GLBT) families and the nature of discrimination against them; (b) school factors that hinder and facilitate equity for GLBT families; (c) instituting change through organizational consultation or large group-level strategies; and (d) instituting change through traditional consultation or small group and individual level strategies. Taking an ecological perspective, the school is viewed as a system trying to maintain the status quo in the face of increasing pressures to change. The need for systemic change when establishing antiharassment and GLBT-friendly environments in schools is highlighted. The consultant identifies the obstacles hindering change and empowers the system to reorganize itself and connect with resources that will help establish collaboration between straight and gay members of the school community. This role requires a unique combination of expertise in social processes, group dynamics, organizational change, and GLBT issues. Specific consultant strategies for small groups and individuals are identified. Resources for consultants and future research directions also are provided.  相似文献
