In my last column, I argued that one’s senses, curiosity, and the spatial perspective are essential for understanding our world and for making the most out of field experiences. In this column I wish to make the case that these three things guide the questions you ask. And the questions that you ask are most important thing about any investigation, and about learning.
I also believe that you must be comfortable with the fact that in our complex world, some of the questions cannot be answered without additional investigation, and that some of the questions indeed may never be fully answered. In our world of instant information and standardized testing, quick and easy answers are difficult for many students—and sometimes, instructors—to accept.
Consider a recent video I made on the beach on the coast of the Caribbean Sea where I asked a series of geographic questions. I considered issues in physical geography including sediment transport along coasts, beach sand, storm surges, and hurricanes, and issues in cultural geography including the pros and cons of developing resorts along coasts. I could partly answer some questions I posed in a few minutes, while others I left open for students and instructors to discuss in class.
The questions you ask determine what data and information you will collect, what devices you require, and what methods you will use. We certainly have more means of collecting data than ever before. I believe that geographers from Eratosthenes to Davis would have been thrilled to have and use the tools we have today. We also have an expanding number of ways to map field-collected data. Some of these ways even allow for something that many of us have longed for years to be able to do—to collaboratively and simultaneously gather data in their real-world coordinates by a group of students while out in the field, and have that data automatically appear on a continuously updating map. These can be done using the Student Data Mapper or from shared Google spreadsheets as developed by my colleague Tom Baker, or via editable feature services using ArcGIS 10.1 and ArcGIS Online as shown in the image below.
Yet unless we are curious, using our senses, asking insightful, thoughtful questions, and using the spatial perspective, the effectiveness of even these tools will be limited. What are some of the means you have used to foster good questions to be grappled with?

A new book from Esri Press entitled Tribal GIS: Supporting Native American Decision Making, will be published in June 2012. In it, tribal leaders tell their stories about implementing and using GIS to address their unique challenges as sovereign Nations. The book covers applications in natural resources and the environment, transportation, cultural and historical preservation, economic development, health, public safety, agriculture, and perhaps most interesting to the GIS education community, two chapters on K-12 and higher education. Showing how tribal governments responsible for the stewardship of their land and resources and the health and well-being of their People use enterprise GIS to make decisions, Tribal GIS supports tribes new to GIS and those with GIS experience. It also will be useful for the general GIS community, showing the many scales and disciplines in which GIS can be applied.
It was an honor to work on this book with so many visionary people who are making a positive difference in the lives of people, in their communities and on their lands, and beyond. The book includes dozens of stories written by educators, scientists, administrators, managers, and others, showing the diversity of their backgrounds but also a common vision for the benefits that spatial analysis and GIS bring to their everyday decision making. Editors of the book include Anne Taylor, who coordinates Esri’s Tribal program, David Gadsden, who coordinates Esri’s nonprofit organization program, Joseph Kerski, who serves in Esri’s education program, and Heather Warren, who is the marketing coordinator for the federal government industry at Esri.
The education chapters include stories such as students at the Alamo Navajo School collecting water well location and water quality information for the tribal government, students at Santa Fe Indian School measuring soil erosion and analyzing land use, students at Haskell Indian Nations University researching the geology of Antarctica and developing an accessibility map for their own campus, and much more.
Space does not permit me to say too much here, but the stories speak for themselves. Pick up a copy of the book, read these stories, and share them with your students. How have the spatial perspective and GIS made a positive difference and aided with decision making? How might you be able to use these stories to generate ideas for your own GIS-based projects?

A few years ago a couple of Colorado chemistry teachers realized that they were spending incredible amounts of time preparing make-up work and documenting the day’s instruction for students who were out sick. To help curb this time problem, they began recording their instruction and placing instructional video (e.g. narrated PowerPoint), class exercises, interactive simulations and other materials online every day – as a regular component of their instructional preparations. What they found was that not only did the resources help the absent student but also students who attended class leveraged the online materials as an opportunity to review. Today, the art and practice of the flipped classroom has evolved. With the day’s instruction shifted to an online format for evening study by students, the 45-minute class period has opened up, allowing time for collaborative projects, deeper, open-ended investigations, or concentrated study of a particularly sticky topic. The Kahn Academy is one popular implementation of pre-built materials, potentially useful for a flipped learning environment.
With the advent of a variety of web GIS tools (like ArcGIS Online) and an explosion of existing instructional video on basic GIS activities (YouTube or ArcGIS videos), the flipped classroom may be a great approach.
While creating new instructional video can be very time-consuming, carefully plotting out the best way to explain a concept, the best examples, and the right formative assessment, the payoffs can be huge (best practices: meta-analysis and practical tips). Teachers using flipped models of instruction report having more time to spend directly responding to students, stronger levels of student engagement, and more time for projects. What a great opportunity to use GIS to launch a class wide investigation of any number of environmental issues or sociological studies. ArcGIS Online can be used to both teach basic concepts in the evening and serve as the collaborative focal point during the day. So whether you’re teaching a STEM subject, geography, or anything else, consider trying a flipped classroom – even for part of the instructional period and explore where you and GIS can take your students.

“How do I start?” That’s what people ask before beginning to take pictures, play a musical instrument, drive a new type of vehicle, swim, or use GIS in education. For the latter, my advice is simple: ArcGIS Online. Students and teachers alike can begin making interesting maps in seconds with ArcGIS Online. New options can be discovered and practiced easily, building thinking skills, technical capacity, and background knowledge.
When making a map, one’s first instinct is usually “Let me see where I live.” Imagery is a useful starting point, because it looks familiar, and ArcGIS Online offers two different imagery basemaps so, right away, one can explore and ask questions about differences in “look.” But imagery alone is insufficient; one needs to add landmarks, labels, and “thematic descriptors.” With ArcGIS Online, it is easy to engage professionally prepared reference and analytical data with which to enhance contemplation of a broad range of topics and questions.
Such mapmaking builds the most essential capacities for understanding the world: locational awareness, pattern recognition, and a sense of data. Being an effective baseball player is not simply a matter of throwing, catching, and hitting a round object; it requires a sense of the game, the landscape, the rules. Using GIS requires a sense of the world local to global, a grasp of diverse elements in different places, the ways these can be represented and melded, and how the data can be analyzed. But using GIS doesn’t just require these, it also fosters them. With ArcGIS Online, learners from elementary school on up can quickly merge basemaps, operational layers, and personal data to represent and analyze phenomena. The concepts supported by these skills are essential for doing any more technologically complex geographic analysis, such as working with ArcGIS Desktop.
Educators getting started have a special opportunity — a free short online class designed just for you! You can do it in an evening and have time left over to figure out how to modify the next day’s class. See “Teaching with GIS: Intro to Using GIS in the Classroom.”
For educators and mentors who want to help students use GIS, start with ArcGIS Online. Emphasize maps of personal relevance, and encourage analysis — classification, symbolization by attribute, selection by rule — to clarify patterns and relationships. Promote investment with projects requiring research; foster critical thinking via frequent construction and analysis of one’s own data; maximize feedback with collaborative work; and use presentation to peers and others for both instruction and inspiration.
When students — or educators — grasp the power of geographic thinking and careful analysis of spatial data, they have the fundamentals in place to support a move into more robust technologies. Getting a good start, with an appropriate first step, goes a long way to making any mission a success.

I’m always looking for good opportunities to teach my kids about GIS. Recently I was presented with a great opportunity to do just this when my daughter, Sarah, was selling Girl Scout cookies. Sarah was very excited to sell lots of cookies so we headed out in our coats to sell to our neighborhood. The first day we had some sales, some “no’s”, and many folks not home. The next day we were excited to get selling again but we had a problem. What if my wife was going to take Sarah out to sell cookies? How would I easily communicate to her which people declined and which were not home? This would get even more difficult if we didn’t get to everyone the next day. All we needed was a simple map where we could draw all the houses where people either bought or declined. I decided to see if we could use ArcGIS to solve this problem and teach Sarah a bit along the way.
Sarah helped by reading off the cookie names while I added them as fields to a geodatabase feature class. Each field would store a count of the number of cookies purchased at that location. I added a couple more fields for information like the sales girl (Sarah), customer name, total boxes sold, etc. I then created a simple map that showed sales in red and “no’s” in gray. Then I published the map with feature access to ArcGIS Server and added the resulting map services to a new web map in ArcGIS.com. Together we used the find feature in the ArcGIS.com map to find all the addresses from the day before and add all our sales to the map. The resulting map looked like this.
At this point Sarah started to understand how the places we walked the day before related to the map.
Before we headed out to sell cookies again I loaded this web map on my iPhone using the ArcGIS for iOS application. I showed Sarah how she could tap on any of the existing sales to see what was purchased there.
Then whenever we left a house, we took an extra minute to enter the new data. We used the data collection feature of the ArcGIS for iOS application to enter the GPS and sales information. I was really surprised at how quickly my seven year old daughter picked this up.
I showed her how to enter the first location and she basically took it from there. That is until her fingers got cold, then she delegated data entry to her father.
So Sarah got a good understanding of how to collect the data and how it could help her quickly find the houses that we still needed to visit. After all the orders came in, we used ArcGIS again to help deliver the cookies. We loaded the wagon and Sarah used the iPhone to tell us where to go and what to deliver.
Once we delivered cookies and received payment, she would take care of marking the customer as paid in the GIS. Since everyone wasn’t home the first time we went out, we then needed an easy way to quickly show where we needed to deliver cookies. To make this easy I opened the ArcGIS.com map in ArcGIS Explorer Online and built a query called “Needs Delivery”.
Sarah could then use the query in the ArcGIS for iOS application to see where we needed to go. This was a great teaching opportunity. Sarah learned that a GIS lets you ask the map questions.
Using ArcGIS.com and ArcGIS for iOS was a great way to teach my daughter about GIS. For Sarah I think her favorite part was the arrow that showed up on our GPS location showing our current direction on the map. For me I it was a fun use of the technology and a fun time with Sarah.

Educational research shows that students can learn both about content and about thinking strategies by working through what are known as “ill-structured” problems. The ill-structured problem is fundamental to problem-based learning (PBL), where students probe deeply into issues, searching for connections, grappling with uncertainty, and using knowledge to fashion solutions. As Stepien and Gallagher (1993) state, “As with real problems, students encountering ill-structured problems will not have most of the relevant information needed to solve the problem at the outset. Nor will they know exactly what actions are required for resolution. After they tackle the problem, the definition of the problem may change. And even after they propose a solution, the students will never be sure they have made the right decision. They will have had the experience of having to make the best possible decision based on the information at hand. They will also have had a stake in the problem.”
In my work with educators and students over the years, I have found that GIS is very well suited to the ill-structured problem. In fact, oftentimes, the best GIS problems are those that fit at least a few of the “ill-structured” criteria above. GIS was created to solve complex problems at multiple scales and from multiple viewpoints. Data in a GIS are imperfect, and are full of uncertainties, and students who work with them become critical consumers of data, an important 21st Century skill.
Students are often so used to a single “right” answer, and are initially baffled by PBL-based strategies and tools that engage those strategies such as GIS. Typically when I work with students using GIS, they ask me, “Is my map right?” In response, I ask them a question: “Does your map help you understand the problem or issue, and help you answer the questions being asked?” But, given time, they begin to understand that the issues they are grappling with are complex, and there might not be a single correct answer. Certainly, their final set of maps is not the end goal, but a means to an end in their inquiry-driven investigation.
For example, in the lesson that I created on analyzing the Hungary toxic flood of 2010 using ArcGIS Explorer, the environmental consequences of the flood are numerous, long-lasting, and occur at multiple scales. I ask the students to compare this incident with other toxic spills around the world, ending the lesson with asking students to analyze sources of toxins in their own community. Student answers will vary depending on where they live and how they judge the severity of different toxic spills around the world. If they can justify their answers, and back up their answers with data, including spatial data analyzed with their GIS tools, then I believe that their answers deserve high marks.
How can you design ill-structured problems using spatial analysis and GIS?

If kids in Arkansas ran our schools, EAST would head in all directions. “EAST” (originally “Environmental And Spatial Technologies”) is an educational project in about 180 schools in Arkansas, plus another handful beyond. It’s a high-tech, service-oriented, student-driven, interdisciplinary, project-based learning operation. It’s where school and life merge. It’s STEM plus social studies, CTE plus English/arts, service plus gym, all rolled into one, on steroids. And at EAST Conference last week, students from grades 4-12 showed what they can do when permitted to grab the reins. (See also the 2010 column, “Fun With GIS #40: GIS and EdReform.”)
Every year, looking at their projects, and watching the students during conference, I see how much kids want to learn, be involved in the community, be helpful, and make the world a better place. Students are charged with conceiving, designing, conducting, trouble-shooting, and assessing projects of significance, and presenting their work to the world. Juggling a buffet of technology, they need to figure out what questions to ask in order to learn what they need, and do what they must to accomplish their task. The adults are “facilitators”, in title and behavior; they monitor and ask questions, offer counsel and point out opportunities, but let each student “drive his or her own bus.” Kids get the chance to try, stumble, grapple, explore new routes, research and study online, seek help from other students over the Internet or even -gasp!- adults out in the real world, problem-solve, create, and innovate. Since all work aims to benefit others – in the school, the community, or halfway around the world – students push hard to succeed and help out.
Many students work with GIS … full ArcInfo 10 and extensions. They don’t know they “can’t do it;” they just learn it. They build and gather data, wrestle with the complexity of the world, manage a blizzard of toolbars and buttons with aplomb, and focus constantly on what will help them move down the road toward their goal. They learn uncommon volumes of life lessons which, independent research has shown, helps them both feel responsible for their own learning and seek extraordinarily to enhance it. In GIS projects, their methods can be haphazard, their strategies a bit unorthodox, their processes circuitous, and “operational efficiency” erratic, but they pursue their goals with unbridled zest and passion, building banks of related knowledge even at a young age.
I judged projects cataloguing local land use change, improving school bus routes, and constructing trail maps for the public. I listened to students new to GIS puzzle thru spatial queries to determine voting patterns when a local millage vote failed. I saw parcel maps highlighting irregularities in local funding. Students spoke of staying hours late to collaborate with peers from other classes, grades, and schools, or work solo in the wee hours before school. And I talked with EAST alums, including young men and women who had earned full-ride scholarships to college on the basis of their demonstrated competency, and heard them describe with maturity their studies, work, and life plans.
With a few minutes to speak at opening assembly, I told the 2000 students that I had spent the previous weekend listening to the nation’s governors struggling with how to “fix education” in their states. But these youth knew the answer. At the final banquet, Arkansas Commissioner of Education Dr. Tom Kimbrell asked the crowd “How many of you would like to see your other classes operate like EAST does?” The thunderous reply declared in no uncertain terms, that if students from Arkansas ran US schools, the light from EAST would shine out in all directions, developing strong kids, building communities, serving the country, and making the world a better place.

Last week I wrote about what several geographers consider to be the “grand challenges of Geographic Information Sciences.” But to grapple with these grand challenges, we need to have people moving into the field of GIScience in the first place. To do that, we must engage students in thinking about their community, region, country, and world in a geospatial context, beginning at young ages. How can we help students to see that every major current issue—from natural hazards, biodiversity, agriculture, energy, water quality and availability, human health, social justice, politics, migration, climate, crime, and many more—are inextricably linked to geographic processes that occur over space and time? Using GIS is one powerful way of seeing these patterns, processes, and connections.
Students using GIS apply scientific inquiry—ask a question, gather data, understand data, analyze data, draw conclusions, and develop a fuller understanding about a particular issue. One of my favorite aspects of using GIS in instruction is that it helps to understand change. Changes from human and natural causes occur all around us, and if students analyze why and how things change, then they can begin thinking on a deeper level: Should the Earth be changing in these ways? Is there anything that I could or should be doing about it? This captures not only the heart of spatial thinking, inquiry and problem-based learning, but also empowers students as they become decision-makers to make a difference in this changing world of ours. GIS has ties to many disciplines, but a natural home for GIS in education is in geography, which has not seen consistent and high support over the past century in American education. How can we change this?
I stated above that we must engage students in thinking spatially. But before that can happen, we must engage students, period. Too often, students are bored, viewing education as something that ends as soon as they graduate, instead of being a lifelong learning experience. We must allow them the freedom, support, and tools so that they can discover and pursue their interests. This may be the grandest challenge of all.
All of the topics raised here can be debated and expanded. I look forward to your thoughts.
