School's out for summer, but that doesn't mean the learning ends for teachers or students. Open source education applications offer a great option for students who are looking to get ahead or catch up over the summer. And summer is an ideal time for educators to find out more about some of the free open source tools available to help them in the classroom.

There are several good reasons why educators should try open source software, most notably financial savings. Many, many schools are facing budget cuts in the coming year, and those schools could realize significant savings by switching from proprietary to open source software. In addition, schools with knowledgeable IT staff can adapt open source software so that it meets their needs exactly –something that's all but impossible with closed source software.

Last June, we published a list of 55 Open Source Tools that Replace Popular Education Apps. This year, we've updated the list and added several new applications. If you're a teacher, student or parent, we hope you'll find at least a few apps on the list that will be useful. And as always, if we've missed any open source education apps that you think we should have included, feel free to add them in the comments section below.
