The Browse mode enables you to find features and principles using any combination
between: a) the search option, b) the filters, and c) connections between features
and principles. The Browse mode also provides opportunities for online
discussions about each of the entries to the database. There is no need to register
and login to act in the Browse mode.
Using the Search option
The easiest way to find features and principles which interest you is by using
the Search option (on the Browse Mode menu). For instance, if you are looking
for features that illustrate the Rock Cycle system, Just type "Rock cycle"
in the search window and click "go".
If you want to be less specific than in the previous example, you might want
to use the "Subject" filter to find all features in earth science.
If that's too general you can continue and filter the results by using the "Audience"
filter to find those features that are earth science middle school, and continue
with the "Category" filter to reduce the list to features that are
visualization tools for middle school earth science.
Browsing through connections between features and principles
After finding a feature you are interested in, and viewing its details, you
can click on one of the Pragmatic Principles connected to it, and learn more
about the general rationale which guided the design of this feature. For instance,
if you click Manipulative
animated 3D illustrations in Geo3D, you'll see that it is connected to a
few Pragmatic Principles. One of them is Reduce
visual complexity to help learners recognize salient information. Clicking
on this link would show the details of this design principle, and would also
show other features connected with this pragmatic principle. Many times viewing
other features related to a principle helps understand the scope and meaning
of the principle.
