Scheme Resources

There are many Scheme implementations. We use PLT Scheme because it includes DrScheme, a student-friendly development environment.

To get help on Scheme, first check the Help Desk under the Help menu in DrScheme. The Help Desk has information on what's available in each language subset and each TeachPack. Some of these resources require being online, but many are local to your machine.

MacOS note: The first time you access the Help Desk, a dialog box about opening a downloaded web page may appear with several buttons. Choose Open not Show Web Page to get the Help Desk. This dialog only appears the first time.
