Discipline Specific Freeware

Below are links to some freeware that I have tested out and found potentially useful for classroom instruction. I do not provide complete sets of instructions on how to use the software, but only a brief description of what the software does and how it might be useful in the classroom. Should you find any dead links, or have any suggestions of software to add to the list please contact me. Also, if the link fails for you, most of these apps can easily be found by searching for them in Google or your favorite search engine.

Just a reminder: I have tested these applications on a MacBook Pro running OS 10.5.8 (Tiger), and there are no guarantees, and CTSS has no responsibility to install and support these applications. With that said, let me know if you have any questions, and I will be happy to do what I can to help you.

Celestia

Celestia is a 3-D astronomy program created by Chris Laurel. The program is based on the Hipparcos Catalogue (HIP) and allows users to travel through an extensive universe, modeled after reality, at any speed, in any direction and at any time in history. Celestia displays and interacts with objects ranging in scale from artificial satellites to entire galaxies in three dimensions using OpenGL, from perspectives which would not be possible from a classic planetarium or other ground based display.

R

R is a free software environment for statistical computing and graphics. It compiles and runs on a wide variety of UNIX platforms, Windows and MacOS.

GeoGebra

From their own website "GeoGebra is a free and multi-platform dynamic mathematics software for all levels of education that joins geometry, algebra, tables, graphing, statistics and calculus in one easy-to-use package." I have just begun playing around with it, myself, but have found that users make ample-use of wikis and discussion forums (links on the site) and provide a generous amount of content to use with the application.
