in background)
Welcome to the Round Earth project at the University of Illinois at Chicago. Here in Illinois, the Earth looks pretty flat, and like most young children, young Illinois children believe the Earth IS flat. |

0:15 | The spherical Earth is a simple example of a 'deep idea' - a fundamental concept that lies underneath our extensive systems of domain knowledge and influences how experience and discourse are conceptualized. |

0.20 | The acquisition of deep ideas, deep learning, involves a paradox - while the intent is to replace the learner's existing ideas, those exisiting ideas are the learner's main tools for assimilating the new idea. The typical outcome of trying to replace these ideas with more fundamental ideas is distortion. |

0.25 | Because of this, deep learning may require
an alternative congitive starting point, where the new concept can be learned
independant of the conflicting prior experience. We are using Virtual Reality
to help generate this alternative starting point.
For learning about the sphericality of the Earth the children can start off on a small asteroid like this one. |

to investigate this approach.

0.25 | A pair of children collaborate in this learning activity on the asteroid.
Their mission is to collect enough fuel cells from the surface to allow
their stranded spaceship to leave. Neither child can complete the task
alone - they must cooperate.
One child acting as the astronaut explores the surface of the asteroid from the Immersadesk. |

0.20 | The second child acting as mission control
guides the first child from a stereo monitor.
This child sees the asteroid as a sphere with the astronaut and the fuel cells visible on its surface. The astronaut may be visibly 'upside down' to this child while the astronaut is always 'rightside up' at the immersadesk |

0.20 | Once the children have completed their mission,
bridging activities are used to relate this new experience on the asteroid
back to their everyday experience on the Earth
This structured dialogue prompts reflection on the VR experience using physical models of the asteroid and the Earth |

- montage of still images from tests? or use live footage from a pre or post-test? how about actual drawings from post test? | dissolve to this | 0.30 | The children are interviewed before and after
the experience. The questions probe their understanding of the shape of
the Earth and the implications of that fact such as the relativity of up
and down, occlusion by curvature, and circumnavigation
These questions are asked 3 ways: verbally, using 2 dimensional drawings, and using 3 dimensional playdoh, to minimize representational bias. |

0.15 | Our initial studies show significant improvement in the treatment group between the pre-test and the post-test, allowing them to catch up with their classmates who had acquired the concept. |
![]() grey version of logo or ??do another montage of the kids like in NICE video - maybe another mix of CG and live photos |

0.30 | Tele-Immersive virtual environments such
as this one have great potential for encouraging jigsawed collaboration
and enhancing understanding through multiple representations and viewpoints
We are continuing to focus on learning goals that meet 3 criteria - they be important. - they must be hard. - and they must be plausibly enhanced by immersive VR These environments must be informed by contemporary research in the learning sciences and educational practice, and will be built with the close cooperation of teachers |
