在这个活动中，需要一到两个课时，可以在高中和高等教育中使用，你有机会通过创建和解释图表和绘制决定系数来提高你的数学知识。在ArcGIS Online中打开以下网络地图:https://www.arcgis.com/apps/mapviewer/index.html?webmap=4168c7a43f6d423dad872796af9f9c9e该地图在一定程度上显示了美国科罗拉多州，可见两层:科罗拉多州14ers(海拔超过14000英尺的山峰)和ACS(美国社区调查)来自美国人口普查局的县级住房和收入数据。在地图的左边，使用层>关闭ACS层>，这样只有山峰是可见的。如果打开该层后面的数据表，您将看到存在58条记录，对应于满足该海拔高度的峰值数量。你还会注意到存在一个名为Elevation的字段和另一个名为Difficulty的字段。难度从1(最难)到58(最不难)进行排序。生成难度的标准包括(1)攀登持续时间和徒步旅行中固有的挑战，(2)地形稳定性，(3)悬崖暴露，(4)是否有步道，(5)海拔增加，以及(6)往返徒步旅行的总距离。因此，困难实际上是一个包含6个不同标准的指数。海拔和难度之间有关系吗?为了找到答案，您将创建一个图表，并创建适合该图表的决定系数。 To the right of the map > Configure Chart > Add Chart > Scatter Plot > Data > X-axis: Difficulty. Y-axis: Elevation > Show Linear Trend (the coefficient of determinations) > observe your chart (shown here). Hover your touchpad or mouse over some of the points on the scatter plot to observe their values (elevation and difficulty). Based on what you learned in this book about the R squared value, is there a relationship between difficulty and elevation? How strong or weak is it? Why do you suppose this is the case? Next, turn on the layer ACS Household Income Distribution Variables > Expand > County > Configure Charts > Add Chart > Scatter Plot > X-axis: Median Home Value for owner-occupied units. Y-axis: Median Household income in past 12 months > Show linear trend (shown here). Based on what you learned in your courses about the meaning of the R squared value, is there a relationship between median home value and median household income? How strong or weak is it? Why do you suppose this is the case? Do you think the same relationship would exist for other states? Note the presence of mountains in Colorado from the presence of 14-ers and the shaded relief base map that is in use. Traditionally, it has been more expensive to build homes in the mountains and to be able to afford to live there. Use your mouse or touchpad to click on a point in the scatterplot where the home value is high and the household income is high. Use the shift key to select additional points (or use shift-and-band an area on the scatterplot to do so). Use the “lower” symbol to minimize the area occupied by the table so you can see the map. Where in Colorado are these higher income and higher home value areas? Do they correspond with the most mountainous areas of the state? Conversely, repeat this procedure for the lower income and lower home value areas in the state, noting any geographic region(s) in the state in which these are concentrated. Do these areas correspond to the Great Plains region of Colorado to the east and the canyons and high plateaus of the northwest part of the state? Note that the above activity does not require you to sign in to ArcGIS Online to work through it. This is one of the instructionally appealing aspects to modern GIS as evidenced in ArcGIS Online: You and your students can engage with it in a variety of ways; here, without signing in. To save your work, however, and to explore additional functionality, you would need to sign in as a named user using your school, college, university, or other account. For more activities that bridge the boundaries between geography, GIS, and mathematics, see the book that Dr Sandra Lach Arlinghaus and I authored, Spatial Mathematics. I look forward to hearing your reactions to the above short lesson. --Joseph Kerski ．.．查看更多

我希望借此机会告诉GIS教育界，你们正在做着重要而崇高的工作。许多人梦想着改变世界——你真的在做!你播下的种子将长成森林;你的学生将成为一系列学科的积极变革推动者，他们的工具带着空间思维和地球技术。在你正在做的所有工作中，不要忘记保持活跃——保持运动和保持洗涤——以一种空间的方式!看我的地理拉伸视频——弯曲你的芬兰!提升你的赤道!https://youtu.be/jws9WGqRwkU也要继续洗!这是我在洗手时保持空间聚焦的想法:https://youtu.be/nOvBrtDeIqg我的洗手视频以五大湖为框架，但你可以使用任何一组5——以a开头的城市，世界上最大的五个湖泊，地貌，生物群落，海洋，大陆，内陆国家，5个地理主题，或其他东西。在你自己的教室里尝试一下，让它生动、有趣、有空间! --Joseph Kerski ．.．查看更多

将GIS工具纳入核心学科的资源需求越来越大。这篇文章回顾了这样一种资源，一本名为《用GIS导航世界:世界区域地理的伴侣》的书。我相信这本书对教师和学生非常有用，他们不仅要培养GIS技能，还要培养核心内容的学习，培养空间思维技能，培养批判性思维和解决问题的能力。在过去几十年支持教育界的工作中，我遇到了许多富有创新精神的教师、教授、学生、研究人员、院长、设施经理、图书管理员和许多其他人。我认识的最有创新精神的两位教师是在德克萨斯基督教大学教书的肖恩·克罗蒂和凯尔·沃克。这些教师不仅教授地理信息系统，而且他们还非常积极地将地理信息系统和空间思维作为一种方法论和方法推广到几个不同的学科，包括商业和地理。我们Esri与TCU一直保持着合作关系，例如在商业位置分析领域。在同一份工作中，我遇到了几十个出版商，我一直非常尊重这本书的出版商肯德尔·亨特，以及他们在包括地理学在内的许多学科上的创新作品。这本书可以用于地球和环境科学，甚至社会学，但在地理学中，这本书真正最闪耀，最有用。《用GIS导航世界:世界区域地理的伴侣》名副其实——它是世界区域地理核心概念的伴侣，并以其为基础——规模、文化和物理区域、空间和时间的变化、流动和网络、人类对景观的修改等等。 It does so thoughtfully, with a proper balance between focusing on how to use tools and data and the bigger questions that must be asked and grappled with as the tools and data are being used. The authors thankfully do not attempt to deal with every aspect of geography in the book, but rather, take case studies and problems that highlight specific aspects of our world, such as the geography of a global sporting event, such as the World Cup, or maritime disputes. I think that is the right approach to take in any massive subject such as geography, chemistry, history, and others--as educators we must inspire students' interest in the topic and not drown them in a content deluge. I believe the most useful aspect of the book is its focus on ArcGIS Online as a learning and investigative tool: ArcGIS Online provides enough power and functionality without requiring any software to install and without overwhelming students with too many tools. ArcGIS Online can run on any device, anytime, and contains tools to map, analyze, visualize, and communicate the results of any investigation from local to global scale. The labs demonstrate the power that GIS to solve problems in society: It will be clear to the students that GIS is not just being used to teach with and learn from--that it is used in nonprofits, industry, government, and academia to make smarter decisions. This is the same tool and my approach with many courses I have developed and placed online recently, including this environmental science course . The book can be used as a companion to core readings and lectures in geography in its entirety, or parts of the book can be used to lend an active learning component to, for example, economic inequality, health, or demographic change. The book can be used at the community college or university level and even in upper secondary schools. This book has been around for several years, and indeed, when I talked with the authors about the fact that I intended to write this review, I could imagine what was going through their minds. Writing curricular items tied to any technology as rapidly advancing as GIS is bound to show some screenshots that are out of date and data sets that have moved. That's the case with this book but I believe it does stand up very well to the test of time. Thus I believe it merits attention in the library of relevant teaching materials based on GIS available today. Other resources include Chris Carter's Esri Press book Introduction to Human Geography using ArcGIS Online and my own environmental science course mentioned above and this complete course in modern GIS. As an instructor, you have a wonderful array of teaching resources, geospatial tools, and rich data sources at your fingertips to share with your students, and Crotty and Walker's book is an excellent resource. ．.．查看更多

我在《方向》杂志的同事芭芭莉·杜克和我写了一篇题为《2022年日常生活中的地理:地理如何嵌入我们的日常生活》的文章。我们这么做的兴趣来自于我们多年来对地理思想和地理技术的推广和支持，也来自于我们对Reg Golledge博士及其2000年的文章的长期尊重，他在文章中提出了几个类似的主题。在我们的文章中，我们:讨论在地理教育和地理信息系统技术方面，2022年和2000年有什么变化和什么相同。创建了一个日常生活中的地理信息图。通过Survey123和仪表板创建了一个调查，其中有几个简短的问题，关于你在白天如何思考空间，以及如何使用地理工具和地图。该调查是开放和可共享的。文章在这里:https://www.directionsmag.com/article/11897欢迎参与调查，检查结果的信息图表，并分享!——约瑟夫Kerski ．.．查看更多
