Reform of Teacher Education: An Opportunity for Geographers

Abstract

This paper focuses on the context and major efforts designed to reform teacher education in the nation's universities. An overview of systems governing and impacting teacher education is provided, with focus on the issues and conflicting forces that form the context within which teacher education-and geography education—find themselves. The paper concludes with a discussion of general trends in education reform and renewal and leadership opportunities open to geographers.     

基于网络分析的区域铁路公司建构方法与实证

区域铁路公司是铁路运输市场组织的重要模式之一, 也是铁路改革中的焦点问题之一。 基于经济地理学功能区(结节区)的网络分析方法, 对1991～2005年我国城际铁路货流的空 间组织特征进行了系统分析, 发现我国铁路货物运输联系形成了较为稳定的功能区划, 形成 北京、广州、上海等城市枢纽节点。基于合理运输组织和减少交易成本的组织理念, 提出建 立东北、华北、西北、华中、华东、中南和西南7大区域铁路公司。该研究可以为铁路市场 化改革提供决策支持。

Acoustic-Gravity Waves from Bolide Sources

We have developed a new approach to modeling the acoustic-gravity wave (AGW) radiation from bolide sources. This first effort involves entry modeling of bolide sources that have available satellite data through procedures developed in ReVelle (Earth Moon Planets 95, 441–476, 2004a; in: A. Milani, G. Valsecchi, D. Vokrouhlicky (eds) NEO Fireball Diversity: Energetics-based Entry Modeling and Analysis Techniques, Near-earth Objects: Our Celestial Neighbors (IAU S236), 2007b). Results from the entry modeling are directly coupled to AGW production through line source blast wave theory for the initial wave amplitude and period at (at 10 blast wave radii and perpendicular to the trajectory). The second effort involves the prediction of the formation and or dominance of the propagation of the atmospheric Lamb, edge-wave composite mode in a viscous fluid (Pierce, J. Acoust. Soc. Amer. 35, 1798–1807, 1963) as a function of the source energy, horizontal range and source altitude using the Lamb wave frequency that was deduced directly during the entry modeling and that is used as a surrogate for the source energy. We have also determined that Lamb wave production by bolides at close range decreases dramatically as either the source energy decreases or the source altitude increases. Finally using procedures in Gill (Atmospheric-Ocean Dynamics, 1982) and in Tolstoy (Wave Propagation, 1973), we have analyzed two simple dispersion relationships and have calculated the expected dispersion for the Lamb edge-wave mode and for the excited, propagating internal acoustic waves. Finally, we have used the above formalism to fully evaluate these techniques for four large bolides, namely: the Tunguska bolide of June 30, 1908; the Revelstoke bolide of March 31, 1965; the Crete bolide of June 6, 2002 and the Antarctic bolide of September 3, 2004. Due to page limitations, we will only present results in detail for the Revelstoke bolide.     

浅谈如何提高测绘工程专业学生对遥感原理与方法课程学习的兴趣

结合笔者在中南大学为期9年的遥感原理与方法课程教学实践,分析了中南大学测绘工程专业学生在该课程教学方面的学习态度和课程认识方面的现状,提出在教学过程初期加强学生对遥感历史文化及名人传记的学习,在课程教学期间自己查询专业应用前景及专业最新动态新闻,在上课期间主动向老师提问3种方法,以考核方式计入学生平时成绩,以期增强学生对该课程的学习兴趣和主动学习能力及独立思考能力,为后续遥感专业相关课程的学习奠定一定的基础。在近几年的教学实践过程中,发现该方法有效地提高了学生对该专业课的学习兴趣,学习效果超越往届学生,实践结果充分证明了该方法的有效性。

Exploring Obstacles toEducational Reform: Observations from Finding a Way

This paper examines teachers' expressions of concerns and resistance to the idea of making their classrooms gender equitable. The observations made here arose in the context of the National Science Foundation-funded National Council for Geographic Education Finding A Way project. During Finding A Way summer institutes, teachers were asked to look critically at themselves and reflect on their classroom practices. From their journal entries and personal narratives, it was found that teachers frequently experience powerful emotional responses and cognitive dissonance when asked to address issues of equity in their classrooms. Dissonance, ambivalence, and resistance surfaced most often over the “request” that they become proactive. We found that Finding A Way was most successful with those teachers who were willing to assume the role of “change agents” and who were personally invested in the outcome. Heretofore, professional development research in geography has been remarkably silent on the issue of teacher resistance to educational reform initiatives.
