1. Deep, Round, and Flat: Reaching your Inner Geek Through Visualization Paul Morin Antarctic Geospatial Information Center University of Minnesota Stephen Reynolds School of Earth and Space Exploration Arizona State University

2. If you just got rid of maps, rocks and minerals, geology would be a great course. -Student in the University of Minnesota introductory geology course

3. Visualization is the Primary Barrier to Entry in the Earth Sciences

4. Four Major Display Issues in Earth Science Visualization Depth Map Projection Real Estate Time

5. GeoWall Stereo Projection in the classroom, office and lab Computer hardware from Best Buy Passive stereo 20+ people at a time (220 at a time at ASU) Under $10,000 Small and Portable

6. Assessment: AstroWall

7. Lunar Phase Concept Inventory 20 multiple choice questions Covers only lunar phases Pre-test showed UT El Paso students starting at a disadvantage relative to other universities in the US

8. Lecture Plus GeoWall Using the Lunar Phase Concept Inventory Significant improvements on: Notion of month (97% vs. 76%) CCW orbit (95% vs. 84%) Cause of phases (71% vs 52%) Eclipses (63% vs. 37%) Diff Earth locations (89% vs. 50%) Moon sets in west (66% vs. 47%) Place Moon in 2D orbit (82% vs. 46%) Month between phases (82% vs. 58%) (Turner et al 2003)

9. Topics with Little or no Differences Moonrise/set times Time between different phases Frequency of a phase Rise/set direction (Turner et al 2003)

10. Topography without contours No crashing Inexpensive Will work next year Can be used in the field Anaglyph Maps

11. Student Attitudes Middle school student responses to the statement: "I learned how to understand the maps quickly." Strongly Agree Agree Neutral Disagree Strongly Disagree Murphy, et. al. In press

25. Use Visualizations for Visual Topics, like Topographic Contours

26. Topographic Profiles Via Slices

27. Subsurface Architecture

28. Interaction of Layers and Topography

29. Reading and Interpreting 3D Geologic Maps

30. Reading and Interpreting Other Types of Geologic Information

31. Visualizations on Globes for Atmospheric/Oceanic/Climate data

32. More of Same

33. Use 3D Visualization if 3D is Essential

34. How Do We Use Visualizations? In classroom (controlled by instructor) Students use in lab Student controlled versus automatically plays Importance of peer discussion, multiple representations, and the “mouse effect” Students use online without Instructor Infused into textbooks and other instructional materials Used during assessment

35. Let Students Explore Visual Data Caracas 15.00.a Landslide scars Caracas airport Alluvial fan Caribbean Sea

36. Animas River Let Students Explore Visual Data

37. Implications from Cognitiveand Educational Research • We have two processing systems, each with limited working memory • We use some capacity to reconcile images and words

38. Research Supports Integrating Text into Figures or Using Narration • Two situations • Students using imbedded text retained more and better at transfer (applying knowledge)

39. Research Supports Limiting Redundancy • Two situations • Figure w/ lengthy explanation • Annotated figure only • Students using only annotated figure retained more and were better at transfer

40. Integrating Text and Figures in Instruction, Student Learning, and Assessment

41. Integrating Text and Figures in a Book

42. Integrating Multiple Representations

43. Specifically Teach Students What Each Type of Representation Shows

44. Class Tests of Integrated Visuals and Text Out of 5 possible (average of 8 classes)
