The educational community has discovered open source tools in a big way.
Analysts predict that schools will spend up to $489.9 million on support and services for open source software by 2012, and that only includes charges related to operating systems and learning management systems.
Teachers, professors and home schoolers are using open source applications as part of their educational curriculum for a wide variety of subjects.
In addition, educators have created numerous organizations and Web sites dedicated to open source educational software, including SchoolForge, the Open Source Education Foundation (OSEF), OpenOptions, the National Center for Open Source and Education and FlossEd.org
For this list, we’ve collected educational apps from a variety of categories that can replace popular commercial software.
In many cases, the open source options listed here offer features that aren’t matched by their closed source counterparts. And while we limited our list to 50 apps, you can find many more on the Web.
