This concluding paper examines the contributions in this Guest Issue by locating them within the ongoing debates about the role and contribution of social science research, particularly through the production of journals. Set in the context of on-going attacks on the relevance of social science research and the failure to respond to major crises that affect us all, I argue that the field of educational leadership is an important site for showing the dangers of becoming relevant and accepting that a constructed crisis is a crisis. I argue for intellectual work within the field of educational leadership, and use the critical and socially critical traditions to illuminate this. The papers in this Guest Issue are located in these traditions, and so I examine the contribution made through problematising educational leadership, examining the realities of working lives in schools and conceptualising alternative ways of thinking about professional practice.  相似文献

ABSTRACT

A new methodology is proposed for qualitative discourse analysis (QDA) aimed at gaining enhanced insights into learning possibilities and indicators that arise during classroom group discussions. The constitution of this new methodology has two principle components: a discourse analysis approach that aims to identify the relationships between content and group dynamics; and a network analysis (NA) approach that uses the same data to identify meaning-related structural dynamics found in the data. The proposed methodology pairs these two components to create a supplementary iterative interchange that facilitates the attainment of greater analytic insights than are achievable by either of the two components individually. The critical aspects of the methodology are illustrated and discussed using real classroom data in ways that provide a procedural exemplar. The strengths and limitations of the proposed methodology are also discussed.  相似文献

我国农田土壤酸化调控的科学问题与技术措施   总被引:40,自引:0,他引:40  
我国南方日趋严重的农田土壤酸化不仅导致农作物大幅度减产甚至绝收,而且促进重金属等有害物质在农产品中吸收累积,威胁国家粮食安全和民众健康。但因酸性土壤分布详情不清,作物酸害阈值不明,土壤酸化预测的研究不足,酸化防治技术严重缺乏,红壤酸化没有得到有效控制。采取有效措施改良酸化农田土壤、遏制土壤的持续酸化,将热带和亚热带地区的土壤酸度维持在较低水平,对我国农业可持续发展和乡村振兴战略的实施具有重要意义。  相似文献

This paper constitutes an attempt to explore trends, issues and challenges that emerge when three different cohorts of pre-service teachers debate contemporary issues in science education at the University of Botswana. Apart from the author's experience of teaching the course, the impetus for this study also comes from a growing interest in the contemporary literature in the need for teachers who, in the context of globalization and knowledge economy, are ‘self-reforming’ through continually addressing the key issues of their profession. Unfortunately, the current situation is such that this burden of interrogation falls heaviest on teachers, despite their lack of skills in undertaking the task.  相似文献

In an ‘age of measurement’ where students’ qualification is a hot topic on the political agenda, it is of interest to ask what the function of qualification might implicate in relation to a complex issue as Education for Sustainable Development (ESD) and what function environmental and sustainability issues serve in science education. This paper deals with how secondary and upper secondary teachers in discussions with colleagues articulate qualification in relation to educational aims of ESD. With inspiration from discourse theory, the teachers’ articulations of qualification are analysed and put in relation to other functions of education (qualification, socialisation and subjectification). The results of this study show three discourses of qualification: scientific reasoning, awareness of complexity and to be critical. The discourse of ‘qualification as to be critical’ is articulated as a composite of differing epistemological views. In this discourse, the teachers undulate between rationalistic epistemological views and postmodern views, in a pragmatic way, to articulate a discourse of critical thinking which serves as a reflecting tool to bring about different ways of valuing issues of sustainability, which reformulates ‘matter of facts’ towards ‘matter of concerns’  相似文献

Given the prevailing spirit of teacher frustration regarding current educational policy, the authors perused frequently visited teacher blogs and discussion boards in the summer of 2009 to determine whether teachers are effectively using them to express professionally informed political dissent regarding educational policy. While many teachers are frustrated with educational policies, they are not particularly adept at voicing their dissent against such policies. Many downplay their professional knowledge, avoid overtly political postings, and feel isolated from others who share their views.  相似文献

Critical thinking and skills in defining problems have been among the goals of a computers and society course that had its credits reduced and student number increased. In an attempt to prevent worsening the students' learning, four measures were taken. The results actually improved from a failure rate of 21.5% to 0.7%. This was mainly due to tighter project structure and additional student work. Reduced course material and improved teacher preparation did not seem to have any effect, while more focused project teaching may have contributed to the decreased failure rate. Further improvements may be gained through time estimation in the problem definition process.  相似文献

The present article deals with the incidence of violence cases inTurkish schools. A review of research based on published research reports andunpublished M.Sc. and Ph.D. dissertations is presented and basic lines of researchare discussed. Special emphasis was placed upon culturally specific issues,besides the culturally determined attitudes of parents and teachers. The need for anationwide system for the prevention of violence and corporal punishment wasemphasized.  相似文献
