This section includes information on using the web to teach
(meaning that the students will use the web rather then you, the instructor).
Some of the web demos (below) can
also be incorporated into web-based teaching.
can host a class website. After a brief tutorial, you can
have a site with discussion boards, student access to their grades, interactive
quizes (both graded for real and practice questions on specific material),
and your material with a lot of navigation tools (searches, next page, last
page, etc.). Graders can be given limited access to input grades. Material
can range from straight text chunks in different files to Shockwave, Flash,
- Virtual Earth (CU version--this
is a popular name). At present, an interactive minicourse on thermal convection.
Maintained by Shijie Zhong in Physics.
- Group or individual interactive homework could be developed from
some cgi scripts made for GEOL1020. With revised scripts in 2005, there
is now a description and how-to use these scripts .
Dan Mitchell or Craig Jones could help guide modifications; the existing
scripts use some simple text files to define students and passwords, put
them into groups, and show them information collected by their group. Students "ask" questions
from pulldown menus; answers get added to the group's knowledge base. For
the pre-2005 version, go through
this page and login as testXX with password being 000XX
and XX being between 1 and 25 (groups 1-21 are real student groups from
Spring 2001 or Spring 2003; 22-25 are empty). (This particular example had
each student "examine"
the characteristics of one formation; the group then pooled their answers
to write a geologic history. If somebody else hasn't tried, you can ask
a question through the pulldown menu and checkbox at the bottom of the page).
The 2005 scripts add requesting a topic question for each group and a report
writing capability at the end.
Stuff you might hook up a computer to the big screen to demonstrate
a point, or perhaps that you might add to your own web materials for a course
- "Virtual Structure rock"
(Craig Jones) is a rock that has been photographed and made into a virtual
object (QuickTime). You can spin it about (with more photos, you could roll
it up and down).
(Craig Jones) shows how changing the
thickness of the crust or mantle lid effects elevations. One
just shows the columns of rock, the
shows weight with depth to illustrate how the weights become the
same in the asthensophere. Shockwave plugin required.
- Magnetic field of the Earth
(Craig Jones) will show the orientation and intensity of the Earth's field
at the point where your cursor is; clicking reverses the field. Shockwave
- Modern day Plate Setting of Western U.S. (Craig Jones)
shows shaded topography. Clicking in checkboxes will turn on or off various
overlays (earthquakes, mantle buoyancy, potential energy, plate boundaries,
position of a "typical" fold and thrust).
- Paleogeography "movies" of the southwestern US and the
western hemisphere (Craig Jones) based upon maps made at Northern Arizona
by Ron Blakely. Paleozoic and Precambrian,
Mesozoic, and Cenozoic
pages are online; a single complete Director file is available from Craig.
(Warning: these are big files (several Mb) and require the Shockwave plugin).
- Animations/interactive webpages
of National Park geology (Interactive Geology
Project) has some developing animations of Colorado National Monument, Grand
Canyon, and other places.
movie of Rocky Mountain Cretaceous shorelines developed by
Educational Technology House for Paul Weimar.
Juans Volcanoes movie developed by Educational
Technology House for Paul Weimar.
- Interactive Photo safari shows
photo thumbnails on a schematic map of the western US at different times
in the geologic past. Note there is also a version which might load faster
to start but is slower to change ages.
- Receiver function analysis (Shockwave; Craig Jones) and a demo of how incidence angle effects Ps and reverberations differently.
- EarthBrowser software (shareware,
$20 PC and Mac) displays the globe in an orthographic view. It has fairly
good resolution satellite maps of the Earth as the base for its globe (the
high res stuff only available if you've bought the code) and updates recent
earthquakes, active volcanoes, clouds, and weather from the web. You can
have the globe rotating, can grab it and spin it to look at any part, zoom
in and out, etc. And clicking on an earthquake brings up the NEIC page on
that earthquake; clicking a volcano brings up the Volcano World page on
that volcano. Recently upgraded to 1 km resolution on the satellite image.
- ScienceProf.com (commercial)
has a large number of Earth-science computer and web-based animation/demonstration
materials with physical
geology, intro structure,
analysis and microfabric
Materials and ideas for demonstrations in the classroom of all
Stuff you could incorporate in class, either indices to resources
or local resources.
Any other information of use in teaching (might include lists
of other web sites that CU instructors have found very useful). Includes software
to be used by students.
