Polyview-3DAdrenergic G-protein coupled receptorfunctionally solubilized by self-assemblyinto a 10 nm diameter Nanodisc. Normal transcription requires both theSteve Sligar - U of Illinois DNA-binding domain (BD) and the activation domain (AD) of a transcriptional activator (TA). Science Creative

  29. 29. The Conference brings together:• physical and biological scientists• graphics specialists• cognitive scientistsIn a forum for the critical examination of:• the uses of visual images in the physical and biological sciences and in mathematics• the tools used to create these images, and of• their effectiveness in conveying scientific information to specialist and novice audiences
  30. 30. Visualization in Science & EducationCognitive scientists’understanding of humanperception and cognition guides the research andeducational application of visualizations.Recent Conferences have been preceded byworkshop tutorials on evaluating and creating bettervisualizations.Small, peer-reviewed mini-grants have been awardedpost-Conference tofoster the multidisciplinaryresearch needed to create effective visualization.

  34. 34. 2005 GRC Speaker: Mary Hegarty, Psychology UC Santa Barbara“We are interested in how people make sense of thesecomplex visual-spatial displays and how they use them inlearning, reasoning and problem solving.”“Eye tracking provides an online measure of the informationthat a viewer is accessing while reasoning and solvingproblems with complex visual displays.”
  35. 35. 2003 & 2009 GRC Speaker Barbara Tversky, Psychology Stanford & Columbia University “Animation, Does it Facilitate Learning?” Space: Events:• Animations have not been proven more effective than equivalent static graphics.• Animations that are invented and used in exploring phenomena and data, often by experts in pursuit of understanding, may be effective.• Creating animations may confer benefits to the creators.• Expertise in the specific content and animation may make some animations effective.
  36. 36. 2005 GRC Speaker: Shaaron Ainsworth, Psychology University of NottinghamLearning with Visual & Multiple Representations and Interactive Technologies • examine how different combinations of representations influence learning • identify a set of design principles for successful multi-representational software • develop a model of how people learn with multiple representations

  44. 44. Chemical Reactions: Visualize & Reflect Jennifer Chiu How did making water molecules in Molecular Workbench relate to the balanced equation of 2H2+ O2 ->2H2O“They are related because in order to have no atoms leftover in the workbench, we had to get a certain amount ofoxygen atoms and hydrogen atoms. This number is thesame as the ratios in the balanced equation (2 H2, 1 O2,and you end up with 2H2O molecules).”
