GIS professional development for teachers: lessons learned from high-needs schools

University faculty partners from the Departments of Geography and Instruction and Teacher Education at a large, public university collaborated with K-12 teachers and the leadership of a rural school district in order to investigate the crosscutting content of science, mathematics, and geography through the integration of web-based GIS technologies. The project explored the critical connections among technology, pedagogy, and content with a particular emphasis on developing technology-enhanced, inquiry-based lessons in which the teachers and their students used GIS technologies to analyze, visualize, and present data in real-world contexts. The findings highlight the importance of well-structured professional development that builds community, integrates diverse content and pedagogical expertise, provides feedback and coaching, and is of sufficient duration to effect change.     

基于交通网络空间权重的区域经济空间相关分析——以甘肃省为例

在区域经济中,交通是联系地理空间和区域经济活动的纽带,交通的发达程度决定了各地理单元空间相互作用的广度与深度.针对不同交通模式赋以不同的权重,基于最短加权交通网络,提出新的空间权重矩阵构建方法,构建了交通网络空间权重,与各种传统空间权重一起,对比研究甘肃省各县域单元之间的区域经济的空间相关性.研究结果表明,利用交通网络空间权重生成的空间权重矩阵,能更真实地反映区域间实际的空间过程;甘肃省的区域经济具有空间相关性但不显著,核心城市经济外溢现象不明显.     

中国海洋生态效率时空格局演变及影响要素分析

随着海洋环境问题的日益凸显,海洋经济与海洋生态保护如何协调发展已成为学术界的研究热点。本文使用C2NLS方法对2003-2016年中国沿海11个省区市海洋生态效率进行测度,使用SDE方法对海洋生态效率的时空演进特征进行分析,最后对影响海洋生态效率的因素进行实证探索。结果表明：(1)海洋生态效率整体呈上升趋势,但地区差距并未显著缩小,海洋生态效率的地区分布出现极化趋势。(2)海洋生态效率重心表现出西南向移动特征,东北-西南向的空间格局更加明显。(3)环境规制、海洋科技和对外开放可以有效提高海洋生态效率水平;产业结构效应不显著,可能是由于高污染行业同时具有高产出与高排放的特征导致;区位因素效应不显著,海洋生态效率与地区发展水平之间没有明显的二次型关系,与中国海洋经济整体发展仍处于“倒U”型曲线的上升通道情况相符,部分印证了“环境的库兹涅茨”曲线理论。     

干旱区城市环境与经济协调发展评价与对策研究——以乌鲁木齐市为例

以乌鲁木齐市为例,阐述了其经济与环境发展现状,通过构建乌鲁木齐市环境与经济评价的指标体系,利用协调发展的相关计算模型分析了乌鲁木齐市1985-2004年环境与经济协调发展度的变化及其类型,得出如下结论:乌鲁木齐市环境与经济发展的协调程度类型总体来看可归类于协调发展类型,从动态趋势而言,1985年基本上处于良好协调发展环境滞后型,1990年处于良好协调发展环境滞后衰退型,1995年处于良好协调发展环境滞后增长型,2000年以后一直处于优质协调发展环境滞后增长型。并在此基础上提出一些有利于环境与经济协调发展的对策与建议。     

Monitoring salmon aquaculture waste: The contribution of First Nations’ rights, knowledge, and practices in British Columbia, Canada

British Columbia's current approach to monitoring salmon aquaculture waste is disconnected from political and legal trends towards the recognition of Aboriginal rights in Canada. Drawing on insights from collaborative monitoring in northern Canada and interviews with 23 Kwakwaka’wakw clam-diggers and cultural specialists (2006–2007), preliminary directions for integrating First Nations’ values, knowledge and stewardship practices into marine environmental monitoring are identified. Kwakwaka’wakw monitoring practices include the use of qualitative individual, community and population scale indicators and the integration of traditional knowledge as baseline data about the healthy conditions of traditional food resources.     

Analysis of types and changes of village-level economy in rural Gongyi city,Henan Province since 1990

Based on the research on the rural living standard in China in terms of annual net income per capita, we define six types of village-level economy, i.e. ＂to be extremely poor＂, ＂to make a basic living＂, ＂to dress warmly and eat one＇s fill＂, ＂to try to enrich （to disengage poverty）＂, ＂to be well-off＂ and ＂to be affluent＂. The data of average annual net income of all the 292 villages between 1990 and 2004 in rural Gongyi City, Henan Province were collected, verified and classified. By using standard deviation, coefficient of variation and regression analysis, it is found that the Gongyi＇s rural economy has boosted up remarkably from the relative-poverty and absolute-poverty stages in 1990 to the well-off in 2004. However, the absolute differences between villages present a trend of enlargement, while the relative differences fluctuating. On the other hand, spatial analysis of village-level economy shows that most villages with relatively high economic development level were located along national expressway and most villages with absolute-poverty lay in remote mountainous areas in 1990. Since the 1990s, the rapid urbanization and industrialization have had strongly positive effects on rural economic growth. Initial economic foundation, natural resources and traditional techniques also contribute to village economy. From the perspective of geography, villages with location advantages, such as near urban center or industrial parks, have more chances for their economic development and the ＂core-periphery＂ economic structure has been presented in the process of rural development.

Time to talk knowledge

As part of the secondary school qualification repackaging, the Ministry of Education has requested the geography education community define what constitutes their “critical body of knowledge.” In this article, I discuss three knowledge‐oriented themes focused on: (a) recent assessment trends in geography; (b) the predictive value of NCEA Level 3 geography with 100‐level success and (c) the nature of knowledge as expressed by the New Zealand Curriculum and assessment. Taken together, these themes suggest a need for a serious conversation about knowledge in school geography, as a pre‐cursor to the re‐design of the geography standards matrix.
