Presentation Transcript

  1. Visualization at The King’s University College Peter Mahaffy Brian Martin

  2. Visualization is an integral part of learning: • Seeing and perception • Seeing in the “Minds Eye” • Visualization as metaphor for perceiving • Visualization plays a critical role in understanding – both the understanding of the student as well as the understanding of the researcher • Use of visualizations at King’s plays a vital role in our work with science students… BUT!...

  3. The Myth of Visualization as “Seeing is Believing” • A Simple Task… • Watch the white team and count the exact number of times the white team passes the ball back and forth

  4. The King’s Center for Visualization in Science (KCVS) • Explore ways in which visualization (not just computer based) can be used to enhance understanding: • Among students • Among researchers • Explore ways to implement visualizations into teaching at both secondary and post secondary levels • To work within international communities of scholars researching topics related to visualization

  5. First … a fast breaking news story 3D Visualization at an Affordable Price! The Geowall

  6. Geowall – Technical Considerations Left-channel image Right-channel image Left channel image is projected through the left channel DLP projector and is plane-polarized as shown Right channel image is projected through the right channel DLP projector and is plane-polarized as shown

  7. More on Creating Stereo Images • 3D Image rendering software • Blender – freeware (outstanding package but steep learning curve) • Bryce (more accessible but not free) • Either offset “camera” or scene and render both L and R channel images.

  8. KCVS: Past, Present, Future • Modular Approach to Physics Project (MAP) 1997 – 2004 • Gordon Research Conferences • Centres for Research in Youth, Science Teaching and Learning - CRYSTALS

  9. King’s, KCVS and CRYSTALS • 5 year, 200K/a, Mahaffy (co-PI), Martin (management team &co-PI) • Project involves U of A, King’s, 3 other post-secondaries, Edmonton Schools, Telus World of Science and others • Current projects KCVS will play a role in: • Visualizing Global Climate Change (with NSF) • Ethical Use of Chemicals (with IUPAC)

  10. Applets that Help the Student Visualize Complex Phenomena • Car on a banked roadway

  11. Applets that Help the Student Visualize Complex Phenomena • Thin Film Interference

  12. Visualizing the World Too Small To See: Small Matters Christina deMatteis, University of Nottingham

  13. The Importance of Multiple Representations at the Molecular LevelRoy Tasker, Univ. Western SydneyModels in Chemistry “The most powerful thing you can do when you’re learning chemistry is to zoom down, in your mind’s eye, to the molecular level and try to imagine what is going on and in a sense, try to understand the personalities of the reactants and products… Having each type of model show a different aspect is ideal. Because then students don’t look at a particular model and say: that’s reality.”

  14. "Since garlic hath powers to save from death, bear with it though it makes unsavory breath"Robert of Normandy, 1100 AD • Literature Reports • Allium sativum • Broad spectrum antibacterial activity, including Helicobacter pylori • Antifungal activity • Antiviral activity • Normalization of plasma lipid levels • Stimulates lymphocytes and elicits anti-tumor effects • Anti-hypertensive effects • Bacillus anthracis inhibition?

  15. Several compounds inhibit Bacillus subtilis growth 2D TLC of dichloromethane garlic extract 2nd Dimension–More Polar Solvent 1st Dimension – Less Polar Solvent Initial Spot

  16. Allicin Allicin BioactiveCompound: Allicin E. Block.Agnew. Chem. Int. Ed. Engl. 1992, 31, 1135-1178

  17. Mode of Action of Allicin • Blocks the active site on sulfhydryl enzymes • Interferes with microbial cellular function • DNA & RNA synthesis • Signal transduction & apoptosis

  18. Investigative laboratories For majors and non-majors

  19. Gordon Research Conference on Visualization in Science & Education, Oxford, July 2005 Mahaffy (Chair) Martin (Workshop Leader) Flowing water in SE Jordan NASA Satellite Image

  20. New emphases • Visualization in nanotechnology • Best practices in production and dissemination of educational visualizations • Visualization in genomics and systems biology • Computer graphics / cognitive science interface • Visualization for public understanding of science • Physical models and touch in forming mental models • Geo-Wall 3D visualization applied to other disciplines http://www.grc.org/
