Visualization at The King’s University College

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!...

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

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

First … a fast breaking news story

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

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.

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.”
