50 Open Source Applications for Sci-Tech Education

You don’t have to search very hard to find educators and policy makers worried about the current condition of science, technology, engineering and mathematics (STEM) education in the United States.

There’s a STEM Education Coalition, a National Science Board STEM Education Commission, a Journal of STEM Education and even a STEMEd Caucus in Congress dedicated to passing legislation that increases funding for STEM education.

Organizations like these frequently cite statistics which show that American students lag behind their international counterparts.

For example, in the 2007 Trends in International Science and Math Study (TIMS), U.S. fourth graders placed eleventh in math and eighth in science, while U.S. eighth graders ranked ninth in math and eleventh in science.

Falling behind in these areas could eventually lead to a decline in American innovation, with drastic effects on the economy.

As a result, groups have recently taken a number of steps on local, regional, and national levels to improve interest and achievement in science and mathematics.

The open source community is also doing its part to improve STEM education.

They’ve created dozens of quality open source apps that aid both teachers and researchers, raising the bar for STEM education.

In addition, a number of universities and other organizations have “open sourced” the content of their curriculum, making course materials available online.

This “OpenCourseWare” is becoming increasingly popular. In fact, MIT’s OpenCourseWare project alone had 9.6 million visitors in 2010, most of whom weren’t otherwise associated with the university.

For this list, we collected 50 open source tools – both software and other types of open source projects – that are helping to improve STEM education.

As always, feel free to note any significant projects we might have missed in the comments section below.

Open Source: Astronomy and Space Exploration

1.) Celestia

A perennial favorite, Celestia allows users to view the night skies from any point on earth at any time or to see how the sky would look from any point in the known universe.

The interface is simple to use, and it uses real telescope imagery of stars, planets, asteroids, and other objects in space whenever possible. Operating System: Windows, Linux, OS X.

2.) Stellarium

Stellarium is like having your own personal planetarium on your computer.

In fact, it’s such an accurate depiction of the night sky seen with the naked eye or simple binoculars that it’s used by many planetariums. Operating System: Windows, Linux, OS X.

3.) KStars

KStars offers the same functionality as Stellarium, plus some tools for amateur astronomers, like an observing list, FOV editor, altitude vs. time tool, and more.

It comes with a default catalog of all stars up to magnitude 8, but you can expand it with a catalog of stars up to magnitude 16. Operating System: Windows, Linux.

4.) PP3

An excellent tool for teachers, PP3 creates star charts that are detailed enough for use in PowerPoint presentations or books. Note that in order to use it, you will also need LaTeX. Operating System: Windows, Linux.

5.) Cartes du Ciel (Skycharts)

Another option for creating star charts, Cartes du Ciel uses data from 16 different catalogs.

Don’t let the French name scare you off—there’s plenty of English documentation. Operating System: Windows, Linux, OS X.
