DNA Replication - Simple vs. Rich
Representations
DNA replication is often a difficult scientific concept for students to
visualize. Middle school students with a diverse science background were
eye tracked looking at the steps of DNA replication. Half of the students
were given simple 2-D representations and then their 3-D rich equivalent
image while others were given the rich image and then the simple. |

Topographic
Map Reading
The terrain study was conducted in conjunction with the Distance Education
study using the same subject pool. Debbie Savage, a graduate student in
the College of Natural Resources at NC State created an interactive 3-D
vs. 2-D landform quiz. Using her quiz we were able to eye- track subjects
answering the same questions, but given either a 2-D or a 3-D representation.

Multi-media
in Distance Education
Distance Education is a growing trend among universities and
high school systems. They way information is conveyed in a distance education
curriculum varies greatly from class to class. Building upon previous
research by Dr. Len Annetta and using the eye-tracking lab, three major
styles of teaching via the internet were studied.

3-D Stereo Visualization
An important technological trend in the last five years has
been the reduction in cost of Virtual Reality (VR) technologies. Once
only seen in research labs and military applications, these technologies
are rapidly being integrated into desktop entertainment systems and
will soon be seen in classroom settings. One particular component of
this technology that has garnered particularly strong interest is passive
3D stereo displays. The project team is constructing a prototype 3D
stereo system that will support the display of the kinds of materials
that might be seen in classrooms in the near future, allowing us to
move beyond traditional desktop computer monitors and screen projection
systems. This system will allow us to test our visual materials in an
even broader range of contexts.
For more details on 3-D please see our 3-D stereo projection page here.

Remote
Evaluations of Curricular Material
The Vise project is committed to creating curricular material
to be disseminated throughout the state of North Carolina. We have established
a PolyCom system to allow for teachers to communicate via a web camera
to the researchers as well as provide a setting for observations over
long distances. Please visit our Video Conferencing site developed in conjunction with the Learning Technologies Resource Center, Studio in the College of Education. |
