This article chronicles pace-setting collaborative educational programs which are succeeding in turning around Bronx public schools. It focuses on the results achieved when corporations, universities, cultural institutions, and health-care facilities become partners with the public schools to share their expertise, sophisticated technology, and superior financial resources with the city's children. The marshalling of new resources from outside the school establishment in support of a number of initiatives has set public education in the Bronx on a new course. The transformation of many troubled neighborhood high schools into theme schools which feature a particular career preparation has already brought dramatic changes in the borough's dropout rate and raised the aspirations of large numbers of students.  相似文献

Evolutionary theory predicts that most populations should consist of roughly as many males as females. Recently, a variety of populations have been described which show very different proportions of the two sexes, especially in invertebrate species that contain individuals whose offspring are almost all female. Some of these instances can now be explained by the diverse actions of various ‘selfish’ elements residing in the cytoplasm of the individuals, which are transmitted exclusively through the female line. These instances of curious sex ratios exemplify an important principle: the fitness of genes, rather than of individuals, is the primary currency of evolution.  相似文献

There still appears to be a gap between what online learning promises and what it can deliver in terms of student learning. Developments in online pedagogies and professional learning appear to lag behind the developments in technology and the promised benefits of technological transformation may not be realised. In this paper, we bring together perspectives that highlight vital aspects of online group-learning by reviewing the group-facilitation literature and the latest online learning literature to interrogate the pedagogical theories and practices currently used in online group-learning in higher education. We specifically focus on the interpersonal interactions between teachers and students, which are described in the online learning literature using the terms instructor immediacy, teaching presence, and social presence. We note differences in the literature regarding how teacher presence is interpreted and enacted and we expound the importance of the personal characteristics of the online teacher. Finally, we provide some signposts that might help course designers and teachers to improve online group learning: the intentional use of effective online learning pedagogies; a deeper understanding of what constitutes teacher presence; and strategies to enact that teacher presence with online groups. Recommendations for further research in online group facilitation are provided.  相似文献

Aspects of post‐16 education, particularly with reference to vocational education and training, have acquired a degree of common presentation in the policy making of many national and international organizations in recent years. This paper compares similarities and differences in the rhetoric and reality of policy implementation in Brazil and the UK in post‐16 education, particularly Technical and Vocational Education and Training. It finds an increasing alignment between these two very different countries at the levels of both discourse and practice. It argues that this reflects the dominance of international and regional agencies on whom both countries draw in developing policy, and the subsequent dissemination of those agencies' particular assumptions about the relationship between education, skills and economic performance.  相似文献

The Youth in Transition Survey is used to follow the postsecondary education (PSE) pathways and outcomes of Canadian youth over the mid 2000s. Students starting at community colleges and four year universities are analyzed separately. First program outcomes are reported, showing the proportions of students who leave their first programs but remain in PSE by switching/transferring to other programs, institutions, or levels. Multinomial regression estimates correlates of students’ first program switching and leaving decisions. Five year graduation rates are calculated to show the importance of different pathways (across programs, institutions, and levels) to earning a PSE credential; in the aggregate and for subgroups of students. Transfers constitute important but not terribly large pathways for Canadian students to adjust their PSE and obtain PSE credentials. We calculate the resulting extent to which institution specific measures of persistence, PSE leaving, and graduation rates misstate the rates experienced by students. Compared to American students, university and community college starters in Canada have higher persistence and graduation rates and lower transfer rates across institutions. For community college starters, much of the difference is due to the relative lack of well defined pathways from community colleges to universities in Canada. We find that students with more family resources are better able to transfer across programs or institutions in order to obtain a PSE credential.  相似文献

Severe underrepresentation of African-Americansamong postsecondary faculty is often linked toeducational pipeline supply problems,while institutional variations in demandfor black faculty labor and barriers to theirrecruitment and retention receive less empiricalattention. Using a nationally representative sample ofcollege faculty from a wide array of institutions andscience disciplines, this study investigates linksbetween internal organizational conditions and blackfaculty representation. Hypotheses derive from competingexplanations of the role of race in academicorganizations: institutionalized discrimination to protectdominant group privileges; statistical discriminationbased on expectations of racial group differences inacademic preparation; labor supply and politicalconstraints on black faculty recruitment. A multivariateanalysis examines organizational conditions that promoteor curb these dynamics and their relationship to blackappointments at different tenure levels. Results indicate that although the discipline-specificblack doctoral labor supply is a powerful constraint onthe representation of black faculty, selectiveorganizational contexts are substantial influences as well. Although we find little evidence thatinsulation from competition or segmented faculty labormarkets influence the racial composition of faculties,black faculty are more often found whereinstitutionalized discrimination may be checked by greaterformalization and black constituencies on campus.Consistent with statistical discrimination, blackfaculty are poorly represented at research-orientedinstitutions, even controlling for the scholarly reputationof doctoral credentials.  相似文献

Although the principle of holography was conceived as long ago as 1947, interest was limited until the advent of the laser in 1960 made possible the off-axis holography widely used today. Since then holography has found many applications and become so well known outside the laboratory as to be a recognized art form. Within the last few years considerable progress has also been made in acoustic holography.  相似文献
