EPE Release 2 IOC Review August 7, 2012 What is “Visualization”? Visual Analysis Bioinformatics Information Visualization (InfoVis) Charting Graphing Data Visualization Data Art Visual Analytics “Visual analysis is not primarily about the pictures, but about finding ways to use our powerful visual systems to analyze data. It's analysis done in a visual way. It's visual exploration, visual data analysis, and visual presentation of results.” Robert Kosara, eagereyes.org Explorative Visualization Information Art Information Design Infographics Info Aesthetics Pragmatic Visualization Artistic Visualization Visualization Mapping Cartography Infoporn Chart Junk Scientific Illustration

EPE Release 2 IOC Review August 7, 2012 What Do Educators Want? Top requested features: Data visualization tools (ability to graph, map, chart data) Inquiry-based lessons/activities Lesson plans for teaching science concepts with RTD Locally relevant data sets Map interfaces Stories or case studies that show how scientists use real-time data. Middle-school teachers were more likely to have students use: Computers at school as part of their lessons The Internet/websites at school as part of their lessons Real-time data (mostly student-collected data) as part of their lessons NERRS Real-Time Data Needs Assessment 2006 COSEE NOW Educator Survey 2008

EPE Release 2 IOC Review August 7, 2012 A Scientist’s Glider Visualization Tool Audience Needs: Raw data, Advanced viz & processing tools Challenges: Storage, Processing power, Metadata, Flexibility

EPE Release 2 IOC Review August 7, 2012 And Educator’s Visualization Tool Driving Questions: This tool will allow students to analyze single glider profiles (also called casts) to investigate the following questions: How do measurements vary over the depth of the water column? How does the shape of a particular measurement's profile vary over time and/or location?

EPE Release 2 IOC Review August 7, 2012 EPE Design Philosophy EPE Visualization Tools are designed to be: Customizable –Adapt them to fit your learning goals Embeddable –Place them in context within your lessons Focused –Learning outcome driven not data driven (I.e. these are not your typical comprehensive tool) Simple –Intuitive & easy to use Educational –Primary goal is to aid analysis and understanding of scientific processes, not dealing with data formats and graphing 19

EPE Release 2 IOC Review August 7, 2012 Students use two different properties measured by Slocum gliders to find a water mass with a particular “fingerprint”. Ross Sea, Antarctica “fingerprint:” Temperature = 1.3°C Oxygen concentration = 6.5ml/L Students are guided through the process: 1)Identify where each “fingerprint” property is on the associated data visualization. 2)Identify where the two properties overlap ( m depth, ~600km along segment distance). 3)Use the map of the glider track (not shown) to find the latitude and longitude of that point along the segment. Data lesson: Find your water mass

EPE Release 2 IOC Review August 7, 2012 Version 1: raw glider dataVersion 2: simplified data Most students are lacking data skills: Data orientation (using titles, axes, scales, labels) Identifying trends Map reading; latitude and longitude Including units Students had difficulty -choosing the correct color from the scale -outlining the appropriate color on the data plot. Reduced number of shades on the color scale -Cearly defined boundaries between shades, for both scale bar and data plot Strategies: Model data orientation skills Break analysis into steps Clearly label/bold relevant information Simplify data to make trends stand out LSC: Lessons Learned
