High turnover rates of early care and education teachers reduce the quality of education; unsatisfied teachers, suffering from stress or emotional exhaustion, are less equipped to promote children’s development and more likely to leave the classroom. We used data from a national survey of US early childhood educators (n?=?1129) to examine associations between teachers’ working conditions, well-being, and motivation with professional commitment and turnover intentions to move, leave, or remain. Multiple regression analyses revealed that more intrinsically motivated teachers were more likely to report intentions to move over leave, emotionally exhausted teachers were more likely to report intentions to leave, and lower teacher-reported working conditions predicted intentions to move or leave the field over staying. The results suggest that teachers’ well-being and perceived working conditions relate with their intentions to remain at their job or within the field and to their commitment to the profession. 相似文献

This article describes a pilot project designed to encourage career interest by minority high school students in health professions in geriatrics and gerontology. This multifaceted educational program used a contextual training approach and was conducted over a five-week period. Program components included classroom sessions, group as well as independent activities and research, guided field trips, faculty lectures, and the development of a final report directed at health careers in gerontology. The majority of the students were planning or considering a career in geriatrics or gerontology at the completion of the program. Students' evaluative comments revealed a more positive attitude toward the elderly, significant interest in gerontology careers, and strong support for the program. A strategy for longterm follow-up of participants is presented, as well as lessons learned and plans for future programming. This program was implemented by the Rhode Island Geriatric Education Center, in collaboration with the University of Rhode Island Urban Field Center, in response to the "Kids Into Health Careers" initiative established by the U.S. Bureau of Health Professions. 相似文献

Rigoberta Menchú has become an icon for the struggles of oppressed peoples for justice and self-determination. For many academics and activists around the world, the accusations of lying made against Ms. Menchú by David Stoll brought into sharp focus the politics of "truthmaking" and the absolutist categories of fact and fiction. In this attempt to discredit Ms. Menchú, and through her, the Mayan experience of genocide by the Guatemalan military and its U.S. sponsors, important questions have been raised about how and when Third World women can speak, the conditions under which they will be heard, and the strategies used to silence them. In this paper, the author draws upon some of the lessons of the Rigoberta Menchú case to examine the politics of truth making in Canada in a recent controversy regarding a speech she made criticizing American foreign policy and urging the women's movement to mobilize against America's War on Terrorism. The highly personalized nature of the attacks on the author by political and media elites sought to accomplish a closing down of public space for informed debate about the realities of U.S. foreign policy and to silence dissent. Repeatedly emphasizing her status as an immigrant outsider, this controversy also contributed to the (ongoing) racialization of people of color as a treacherous "enemy" within the nation's geographical borders, against whom "Canadians" had to be mobilized. 相似文献

This commentary on Zins and Illback's (1995) article, Consultation to Facilitate Planned Organizational Change in Schools, argues that the authors provided a solid foundation for well-planned, proactive, sustainable, internally-driven systemic change in schools that has yet to be widely realized. Their school organizational change model and more recent change models provide guidance for realizing a change from an individual, remedial focus to a population-based and preventative practice. 相似文献

A group of 633 college students at a large midwestern public university was asked fifteen questions pertaining to personal long-term course planning. The results indicated that only 48% of the students sketched out a tentative listing of at least two courses per term for one or more subsequent semesters when first planning courses for the current semester. Long-range planning was positively correlated with the number of years students had already spent in college and with students' perception of the following factors: course planning utility, degree of certainty about pursuing one's current first choice of career, and degree of commitment in using college coursework as a means of achieving a career goal (all p < 0.001). Long-range planning was negatively correlated with the anticipation of a possible change in academic interests. Such planning was not significantly correlated with students' entrance examination aptitude scores or grade point averages. Thus, students' long-range planning of courses was associated more strongly with career commitment than with recent academic performance or aptitude. 相似文献
