Researchers have highlighted developmental mentoring as being beneficial and judgmental mentoring as hampering the potential positive outcomes of mentoring. We introduce the construct clear mentoring as a beneficial form of mentoring. The findings suggest that newly qualified teachers who perceive higher levels of mentoring characterized by mentees’ opportunities to reflect upon their own practice, openness to different approaches to being a teacher, and an atmosphere of relational trust are more likely to report lower levels of self-efficacy. In contrast, mentees who perceive higher levels of mentoring characterized by clear communication of feedback and advice are more likely to report higher levels of self-efficacy and lower levels of intention to quit. This study contributes to the field of mentoring by illuminating how mentors’ communication of evaluations, advice, and feedback can positively affect mentees, and how mentoring dominated by mentees’ perspectives can negatively affects mentees.  相似文献

In Europe, universal service developed within a public-service-oriented institutional framework. The historical conflicts that produced these institutional arrangements are still important for national policymaking. Furthermore, the level of technological development and integration in the European Union forms the context in which decisions concerning universal service are made. Our analysis of telecommunications policies in three small European countries - Denmark, the Netherlands, and Norway - shows that business actors are well networked and press for a minimal definition of universal services, whereas those actors promoting an extended definition seem to be less coordinated and therefore less successful. Hence it is unlikely that universal services will be defined more extensively in the future.  相似文献

The legal definition of “emotional disturbance” proposed by the Federal Government under PL 94–142 is Bower's 1957 definition with some modifications. The modifications do serious damage to the integrity of the research and conceptual base from which the definition is drawn. The difficulties inherent in a definition of this type of handicapped are delineated. It is suggested that where policy makers and researchers join together, such relationships are best enhanced when each respects the assumptions and concepts of the other.  相似文献

In this study we explored how dramatic enactments of scientific phenomena and concepts mediate children's learning of scientific meanings along material, social, and representational dimensions. These drama activities were part of two integrated science‐literacy units, Matter and Forest, which we developed and implemented in six urban primary‐school (grades 1st–3rd) classrooms. We examine and discuss the possibilities and challenges that arise as children and teachers engaged in scientific knowing through such experiences. We use Halliday's (1978. Language as social semiotic: The social interpretation of language and meaning. Baltimore, MD: University Park Press) three metafunctions of communicative activity—ideational, interpersonal, and textual—to map out the place of the multimodal drama genre in elementary urban school science classrooms of young children. As the children talked, moved, gestured, and positioned themselves in space, they constructed and shared meanings with their peers and their teachers as they enacted their roles. Through their bodies they negotiated ambiguity and re‐articulated understandings, thus marking this embodied meaning making as a powerful way to engage with science. Furthermore, children's whole bodies became central, explicit tools used to accomplish the goal of representing this imaginary scientific world, as their teachers helped them differentiate it from the real world of the model they were enacting. Their bodies operated on multiple mediated levels: as material objects that moved through space, as social objects that negotiated classroom relationships and rules, and as metaphorical entities that stood for water molecules in different states of matter or for plants, animals, or non‐living entities in a forest food web. Children simultaneously negotiated meanings across all of these levels, and in doing so, acted out improvisational drama as they thought and talked science. © 2009 Wiley Periodicals, Inc.

In this paper, we aim to contribute to ongoing work to uncover the ways in which settler colonialism is entrenched and reified in educational environments and explore lessons learned from an urban Indigenous land-based education project. In this project, we worked to re-center our perceptual habits in Indigenous cosmologies, or land-based perspectives, and came to see land re-becoming itself. Through this recentering, we unearthed some ways in which settler colonialism quietly operates in teaching and learning environments and implicitly and explicitly undermines Indigenous agency and futurity by maintaining and reifying core dimensions of settler colonial relations to land. We describe examples in which teachers and community members explicitly re-engaged land-based perspectives in the design and implementation of a land-based environmental science education that enabled epistemological and ontological centering that significantly impacted learning, agency, and resilience for urban Indigenous youth and families. In this paper, we explore the significance of naming and the ways in which knowledge systems are mobilized in teaching and learning environments in the service of settler futurity. However, we suggest working through these layers of teaching and learning by engaging in land-based pedagogies is necessary to extend and transform the possibilities and impacts of environmental education.  相似文献
