试论“五四”女性新诗的书写特征

中国第一代女性新诗的作者诞生于"五四"启蒙时期,此时的女性自我一般都深受传统文化熏染,同时也接受新思想文化影响,开始与男性共同成为社会活动的积极参与者。同时,初涉于世的稚嫩、现实的复杂、以及对于白话语言的生疏,对其诗歌创作水平产生了较大限制,使这一时期的女性诗歌书写显示出较明显的过渡性特征。     

Practical considerations when supporting transitions for pupils with speech,language and communication needs

This article investigates the impact of transitions upon pupils aged 11–14 with speech, language and communication needs, including specific language impairment and autism. The aim is to identify stress factors, examine whether these affect any subgroups in particular and suggest practical strategies to support pupils through transitions. Stress factors discussed include homework, bullying, independent learning and social situations. The compared subgroups include pupils with diagnosis of SLI and autism, those receiving free school meals and those not, and pupils achieving at different National Curriculum levels. The sample is too small to be representative or generalisable but some recommendations for practice are given.     

Academic induction for teacher educators

This paper is a reflective exploration of major challenges facing new teacher educators as they make the transition into the academy, and of ways that best support them. The transition problems identified in the emerging body of literature about teacher educator career entry were offered for comment to a small group of new teacher educators in an Australian regional university. Their responses added complexity and nuance, suggesting a heterogeneity of entry pathways and experiences, as well as avenues for further inquiry. Consideration of the resulting issues leads to wider questions about the place of teacher education in the academy. In turn, this leads to question if the challenges faced by newly appointed teacher educators are distinctive from those experienced by all new academics. The paper argues for multidisciplinary cohorts for induction, and makes recommendations for systematic, inclusive induction programs for all new academics, including teacher educators. The paper concludes with two further recommendations. First, large‐scale research is required to inform us about the contemporary teacher education workforce. Little is currently known about entry and career pathways, nor of the impact of recent policy and funding changes such as research performativity measures and increasing employment of sessional staff. Second, induction must be seen as an organisational and professional responsibility shared by many, including new and experienced academics, faculties, departments, institutions and professional associations.     

电大开放教育中毕业作业的课程化转型初探

将毕业作业课程化是纠正开放教育毕业实践环节出现的形式化倾向的出路。电大开放教育毕业实践环节,在一定程度上存在着指导理念不严谨,运作模式不合理,资源系统不支持和管理机制不完善的弊端,"毕业作业课程化"在一定程度上、一定范围内可以解决由此带来的相关问题并以课程化的思路提出课程设计方案。

旅游开发视野下的少数民族文化重构

民族旅游的开发导致了少数民族文化的过度理性化、商品化以及少数民族文化分化等问题。同时,民族旅游的开发重塑了少数民族地区人民的民族意识、民族文化价值得以重新估量、少数民族地区人民的生活水平得到较大改善、传统手工艺得以重生与传承。在旅游开发过程中,少数民族文化变迁经历了解构再到重构的过程,实现了少数民族文化的再生产。     

论班主任在新课程改革背景下的角色转变

班主任不仅是班级发展的领导者、学校教育理念的推动者,而且也是家庭教育的深化者和得力助手。因此,班主任的角色定位对整个班级学生,乃至对学校教学活动具有极其重要的作用。传统教育模式下的班主任,更多的是扮演检查者、监督者、保姆和通讯员等不民主的角色。随着新课程改革的实施与推进,班主任角色必须发生如下变化:班主任应该是学生精神上的关怀者、学生学习上的引路人、学生生活上的知心朋友、学生在家校面前的代言人和学生班级中的设计师。
