Geochemistry

Box models

Introductory level

Crystallization of magmas

  • Fractional crystallization
  • Reverse analysis from rock to magma

Old films

  • Britannica
  • What happens to atoms
  • Old animations - convert / update to QuickTime
  • Crystallization of metals
  • Water tank
  • Gravity vs. magnetism
  • Metamorphism

Geologic time

  • Radioactive decay / absolute age determinations

Cognitive levels/experiments
Different versions of a single process to test reliability/viability

Timescales

  • Magnitude of time / space
  • Convey the importance of time and space
  • Move beyond the material
  • Scaling issues
  • Temporal scale - dynamic representation
  • Duration of process in proportion to time
  • Log scaling

Geologic time given a sequence - sort it out and define a chronology of relative time.

Why is time important in earth processes?

Cognitive research questions.

Members: David Rapp, Barbara Tversky, Steve Reynolds, Janice Gobert, Ramon Lopez, Mark Abolins, Kirsten Butcher

What can we do to identify and revise student misconceptions in geosciences?

Mental models: what is the state of geologists and their students?

How do the knowledge structure in experts and novices differ?

Bridging gap between experts and novices- can you use visualizations to bridge that?

How can we develop alternative representations to test empirically. e.g. Difficulties with interactions of layers and topography.

How students are linking multiple representations?

Need to develop a questionnaire for intro geology students.

Collections on the website.

Learning what students see in visualizations.

Members: Cathy Manduca, David Uttal, Basil Tikoff, Kim Kastens

Technology platforms and interoperability.
