We discuss an investigation into the understandings of trainee teachers about government policy, using, as an example, the UK government's ‘Every Child Matters’ (ECM). We discuss the research methods used to gather and analyse data from 197 initial teacher education trainees in three institutions in England drawn from six subject areas. The project focussed on trainees' reactions to the anticipated outcomes of ECM and their confidence to help implement the initiative in their roles as form tutors (home room teachers) and subject teachers. Trainees react positively to ECM but reveal uncertainty about its precise meaning and about the roles they would need to adopt as teachers. We suggest that it is problematic for governments to expect teacher education communities to assist with the implementation of policies that have been inadequately characterised. We make recommendations about the role of initial teacher education in the further development of ECM. 相似文献

“学会共处”作为教育的四大支柱之一,已成为21世纪重要的学习需求。“学会共处”作为学前教育课程的新取向对“文明交往”的同伴共处、“和谐共处”的师幼互动的形成,“关关与共”的幼儿园文化的营造具有积极意义;其价值取向主要在于培养儿童的自我意识、他者意识、群体意识;“学会共处”作为学前教育课程的建设,以弹性的游戏课程的设计、基于教师指导的课程实施和以园本课程制度为依托的课程运行为主要方向。 相似文献

This study examined the extent to which kindergarten children’s academic pre‐skills are associated with their teachers’ subsequent teaching practices. The pre‐skills in reading and math of 1268 children (655 boys, 613 girls) were measured in kindergarten in the fall. A pair of trained observers used the Classroom Assessment Scoring System instrument to observe 49 kindergarten teachers on their emotional support, classroom organisation and instructional support in kindergarten in the spring. The results of the multilevel modelling showed that low levels of academic pre‐skills in kindergarten classrooms in the fall predicted high classroom quality in the classrooms later on. The results suggest that the overall level of children’s academic pre‐skills in the classroom plays an important role in the ways in which teachers adapt their instructional practices to the needs of a particular classroom. 相似文献

ABSTRACTSince the 1990s, the low number of students choosing to study science and technology in higher education has been on the societal agenda and many initiatives have been launched to promote awareness regarding career options. The initiatives particularly focus on increasing enrolment in the engineering programmes. This article describes and compares eight European initiatives that have been established and operated by universities (and in some cases through collaboration with other actors in society). Each initiative is summarised in a short essay that discusses motivation, organisation, pedagogical approach, and activities. The initiatives are characterised by comparing the driving forces behind their creation, how the initiative activities relate to the activities at the university, size based on the number of participants and cost per participant and pedagogical framework. There seem to be two main tracks for building outreach activities, one where outreach activities are based on the university's normal activities, and one where outreach activities are designed specifically for the visiting students. 相似文献
