基于文化感知的宝鸡旅游资源分区及线路开发研究

传统旅游资源分区主要考虑行政区划和地理位置因素,这在一定程度上割裂了旅游资源的文化完整性。旅游资源分区与线路开发应当参考资源的文化特征,从而为旅游者形成完整的旅游文化感知。文章以宝鸡为例,探讨了基于文化感知的旅游资源分区及线路开发的具体方法。     

马克思社会批判的理论维度

现实生活是马克思社会批判的理论基点,它确立了马克思社会批判理论的基本前提,使马克思社会批判理论与其他社会理论的本质性分野得以明证;社会分工是认识社会历史的钥匙,是马克思对资本主义社会展开深度批判的理论支柱,它透析了马克思社会批判的理论架构;马克思对历史之谜的全部解答是对历史构成的整体揭示,奠基了马克思社会批判理论的历史视野,确定了社会批判的理论内涵。

分布式认知视角下促进元认知发展研究——基于多媒体环境

分布式认知理论的提出,为研究认知活动提供了全新的视角,也为元认知培养方式提供了新的可能性。分布式认知理论强调媒体的作用,多媒体环境不仅能为外部表征提供多种辅助手段,还能为认知活动提供具体情境。在多媒体环境下,直观的外部表征、可视化的知识交流和实时线索的提供为元认知培养提供了全新的视角。     

From school leader to educational leader

ABSTRACT

This study builds on research which contends that just as effective principals must lead across a broad purview of responsibilities in order to build successful schools, so too must middle leaders. Decentralisation of school management has resulted in an expansion of school principals’ responsibilities, contributing to a further distribution of leadership responsibility to middle leaders. This conception of middle leadership requires a shift in understanding of the nature of middle leaders’ work. There is vast potential for middle leaders to contribute to their schools beyond subject administration, yet the research base yields limited insight on such work and on how middle leaders can be supported to accomplish it. This research finds that middle leaders who expand their leadership responsibilities do so in contexts that utilise school mission, policy enactment and organisational design as platforms for enhanced middle leadership.     

School teachers' perception about distributed leadership practices for inclusive education in primary schools in Bangladesh

This article reports on the third phase of a larger study that explored the perceptions of teachers about distributed leadership practices for inclusive education (IE) in primary schools involved in IE reform in Bangladesh. The Distributed Leadership Practice for Inclusive Education scale was developed specifically for this study to collect data. Participants for the present study were head teachers and teachers from 308 public primary schools. The results of this study indicate that teachers perceived that distributed leadership practices for IE were present in primary schools in Bangladesh. The findings indicate that teachers' perceptions about distributed leadership practices for IE have a significant positive correlation with their satisfaction about the implementation of IE policy.     

Teacher appraisal*

At the heart of the teachers' dispute is not money but management . . . This dispute is about resistance to change in working practices. The essence of education is discipline . . . By resisting the discipline of assessment of their own performance, the teachers stand opposed to the renovation of Britain. That is why in this dispute management must win ‐ and there is the beginning and end of the lazy comparison that some people have been tempted to make with the coal strike.
