Library leaders must resist the pressures of hierarchical thinking to focus on how they can best enable staff to grow in knowledge and commitment to librarianship. Empowering leadership serves the work-related needs of all employees by ensuring that they understand the significance of their tasks, have sufficient knowledge to perform well, possess a measure of control over their own work, and participate in planning and decision making.  相似文献

Black children generally receive poorer sociometric nominations compared with Whites. This effect is not fully understood because Black children rarely hold a classroom majority and teachers' race is rarely investigated. Research from a person-environment perspective suggests that the effects of children's race depend on the racial composition of the classroom and society's racial attitudes. Sociometric nominations were obtained from 1,268 5th graders, between 9 and 11 years old (53% Black), across 57 classrooms (3-95% Black students). Half of the teachers were Black. The results indicated that ratings of Black children were more influenced by the racial context of classrooms than were ratings of White children. The implications of this study are discussed in relation to group dynamics and racial discrimination.  相似文献

Improving mathematics education in the United States has taken many forms. Our work has focused on two aspects: the content knowledge of teachers and a well-articulated coherent curriculum. Our aim was teacher “capacity building” that is enabling teachers to teach to coherent and significant mathematical curricular goals and describe the implementation in a large-scale project based at Michigan State University. We highlight the design, structure and use of mathematics teacher learning tasks that were intended to improve teachers’ capacity to teach to these goals and note how the teachers’ perceptions of the structure and sequencing of mathematics itself affect the ways they organize mathematics in their teaching and the ways they teach.  相似文献

This account tells the story of the development of an action learning culture in the BBC between 2002 and 2007. From its early beginnings as a sporadic, unsystematic intervention with a small number of leaders scattered throughout the organisation, action learning has now become embedded in our approach to the way we develop our leaders. In this paper we look at the organisational context in which we were developing action learning, the way it became an integral part of a systemic change intervention, the barriers we had to overcome on the way, how we built an internal resource capability and how action learning evolved. We evaluate the impact it has had on the organisation and on our practice, exploring lessons learned during this time and offering ideas for the way ahead.  相似文献
