How does blended learning, flipped classroom concepts and other newfangled education thinking work in GIS? Penn State's Alex Klippel provided some insights yesterday via a webinar. It was part of the University Consortium for Geographic Information Science (UCGIS) series and titled "Blended Learning in a GIScience Course: Lynda and Sketch-based Geo-spatial Learning Objects" but other terms mentioned included: flipped classroom, face-to-face time, cost, BOK, and sketch-based learning objects.
The course in question, spatial analysis (Geog 464) uses R and meets face to face regularly. Students are expected to work through material in an existing Lynda-hosted R course outside of class. That's the "blended/flipped classroom" idea; content learned outside of class is brought to class to be used. This vision of teaching and learning removes, for the most part, the dreaded lecture. The sketch-based learning objects are a second part of the flip. Best I can tell, they are short videos of an instructor creating and discussing a concept. It's what instructors used to do on blackboards, with chalk.
As Klippel discussed his experience with the hybrid implementation of the course he observed:
discussion in class was more active than non-flipped version
students seemed challenged by R (and/or learning R via Lynda; a previous version used ArcGIS)
getting rid of the lecture and only using short mini-lectures was the way to go
creating video material is hard and time consuming
The biggest takeaway for me was the importance and difficulty of planning activities to do in class. Part of the challenge is creating problems on-the-fly that can address questions/obstacles students had with the R assignments. Another part is finding or inventing activities that move students toward the learning goals that take advantage of being together in the classroom.
Klippel cited research by Harvard physics professor Eric Mazur (never heard of him? Check out this NPR piece) who flipped his physics course and has some valuable ideas for using that valuable in-class time for peer learning. One of his techniques is to ask the whole class a physics question with a utile choice answer (A, B, or C). He asks each student to reply (via a clicker or by holding up an A, B, or C card). The percentage of correct answers is typically rather low. Then he asks students to discuss the problem with their neighbor for two minutes. The question is repeated. The percentage getting the correct answer goes way up!
I tried that exact process at a session at the Esri Education GIS Conference. The question: Was a map I showed small or large scale? The original responses were 50/50. After a chat with a neighbor, 100% selected the correct answer.
The bottom line for me: Educators have the tough job of exploring new teaching and learning practices and then implementing them in their area of study. This is not for the faint of heart, but the rewards can be substantial.

In a blog post in the Harvard Business Review, Brian McCarthy, a managing director for Accenture, cautions corporations about drowning in "big data" overload that threatens their ability to prioritize and solve problems.The examples that McCarthy provides illustrate how location-based data is an inherent component to today's big data stream. As such location analytics plays an indespensible role in the problem-solving methodology. For example:
An upstream energy equipment manufacturer, for example, used this approach to better understand the amount of time production equipment sat idling. The company knew there was huge value in solving the idle problem, but it could not do so leveraging traditional technologies as the data volumes were too large (i.e. 300,000 locations, approximately 20 machines per location, 2-300 data points per machine, and 45 millisecond sensor sample rates). Using a Big Data Discovery platform and methodology, within 10 weeks the team was able to show more than $70M in savings from analysis from a subset of the locations and could analyze the data at high speeds (e.g. 13,500 sites, 20 TB, 15 seconds to render).
From this scenario, I believe that the energy company recognized it had a problem that involved a network allocation problem. Using a subset of the data, it was able to make some assumptions about where the equipment was located; how often was it being used; and possiby, could fewer locations be utilized and still maintain service level agreements. It's a fair guess that this was a location-allocation problem.
McCarthy's second example involved "machine learning" and applying predictive analytics and psychogramics:
Machine learning techniques can aid a company to: learn from past behavior and predict behavior of new customers (e.g. risk models to predict consumer risk to default), segment consumer behavior in an optimized, market friendly fashion (e.g. customer lifestyles modeled from geo-location data on cellphones), or conduct crowd simulation models where each customer’s response to a reward is modeled.
Recognizing how social media will become an even bigger part of determining consumer sentiment, the need to acquire and use the location component of real-time streams (e.g. Twitter Firehose) will increase. Therefore, spatial interaction models and spatial statistics become an even bigger part of the arsenal for product and brand managers to analyze these data. Brand managers, then, will need to understand that a significant aspect of their problem is inherently spatial. McCarthy's examples are an indication that many already do.

Health officials have mapped out the places in England which have the highest rates of people admitted to hospital as an emergency for alcohol-related liver disease.
The North West and the North East were pinpointed to be the places with the highest hospital admissions, according to the map [pdf] created by the Health and Social Care Information Centre (HSCIC).
Vaccine Mapping from Hollywood Reporter
The Hollywood Reporter has a great investigation for which it sought the vaccination records of elementary schools all over Los Angeles County. They found that vaccination rates in elite neighborhoods like Santa Monica and Beverly Hills have tanked, and the incidence of whooping cough there has skyrocketed.
The research was covered by The Atlantic.

New Orleans Schools on the Move
The Times Picayune continues to map the changes since Katrina.
With $1.8 billion of repairs and construction under way, New Orleans' public school programs are on the move. Here's the 2014-15 map. (Google Maps Engine, right) and here's a map of how many times a particular program has moved, created by Tulane's Cowen Institute using Tableau.
Bucknell in New Orleans
The school has a nice write-up of an integrated course many of us heard about at Ed UC.
To integrate such vast amounts of material into a compressed timeframe [a week in New Orleans], the trio turned to Janine Glathar, Bucknell's geographic information systems (GIS) specialist. "GIS is a tool that helps you synthesize vast quantities of information and put it into context, which is exactly what this course did with the city of New Orleans. It was a perfect fit," she said.
Mapping Cemeteries and Loving ArcGIS
Two University of Wisconsin-Platteville students are using special computer software to help map the East Side Cemetery in Dodgeville, as part of a summer internship with the Southwestern Wisconsin Regional Planning Commission in Platteville. The project will continue through the end of October.
I like this quote:
"I love working with the ArcGIS software because it is very straightforward to use and there are many ways to represent the data, depending on what the audience wants to see," said Wiederholt. "GIS is an amazing tool that can be useful to someone in any career."
I hope these students have touched other GIS software before they graduate.

Florida's Oil Spill Response
With a goal of more transparency, Florida Department of Environmental Protection, along with Florida Fish and Wildlife Conservation Commission, launched an interactive map complete with photos and descriptions of projects that have been completed, and those in the works or approved for funding, in the wake of the April 2010 [Deepwater Horizon] oil spill disaster.
It's in ArcGIS Online (image right).
Boston Solar Map
Boston Mayor Martin J. Walsh launched Solar System Boston last week. It shows a particular roof’s solar-gathering potential, as well as cost estimates for solar panel installation. The map was created in partnership with Mapdwell, a spinoff from the Massachusetts Institute of Technology, which created some open source tech for the estimates. The map is based nominally on Google Maps.
Tracking Urban Homeless Via GPS
Odense Council in Denmark gave 20 of its homeless GPS devices to carry for a week as part of a voluntary test project. Participants get hot meal tickets for their trouble.
The council wants to know where the homeless move about during the day so it can place coffee rooms and benches strategically and also let the council know where the socially vulnerable community can be found.
