GeoGebra resources on the web
This is a collection of web pages that give some resources for
GeoGebra. Since we are not assured of web access for the
minicourse, these pages are downloaded to the CD.
The place to start is the home
page of GeoGebra, at http://www.geogebra.org/cms/index.php .
As mentioned earlier, one of the links from this page is the download page where you can
download GeoGebra directly. There is also a link to a list of example applets.
The Help function in GeoGebra links to a website. The Help link from the main site
provides a number of options, including downloading the help
information in a pdf file.
Another nice reference is the GeoGebra user forum.
It is an active wiki where you can ask questions and get them
answered. The roughly 2500 participants have made about 20,000
posts.
Besides the forum, there are a number of wiki's associated to GeoGebra
for finding more information.
- Perhaps the most important is the GeoGebra wiki, or at
least the English page.
It is a collection of GeoGebra files and applets so that you can see
what other people have done with the program.
- The Know How
Wiki is a collection of pages addressing how to make things work.
Since GeoGebra is open source with an active community, it continues to
develop. The current stable release is 3.0.4. The next main
release is 3.2.0. The pre-release version is currently at
3.1.205. The Pre-Release
release notes give you an idea of what will be in the next
version. Two technical pages that follow up on issues mentioned
in the workshop - There are pages detailing the applet parameters
and the javascript methods
of Geogebra.
My collection of applets is
at http://www.slu.edu/classes/maymk/GeoGebra/.
Since we are looking at web pages with GeoGebra, it is worthwhile to
discuss html and javascript, two programming languages that are used in
web pages.
- There are a number of html
tutorials available on the web. For the most part you should
be able to avoid learning html by using a WYSIWYG editor, but at some
point you will want to tweak a page and it is good to be able to do
that.
- Javascript is a scripting language that can be used to make web
pages dynamic. We are interested in it because GeoGebra is
Javascript aware. In other words, it can be used to send commands
to applets and to get information back out of the applet. Once
again, there are javascript
tutorials available when you have questions.
