For instructors
Make a link for your class
Teach a subset of the structures? Uncheck the ones you don't cover, add your class name if you like, and share the link at the bottom of this page. The atlas, quiz, and glossary then show only what you left checked, and your selection follows students through every page.
A link looks like torryscott.github.io/lambda/?on=5777777777x7777773776py. That code spells out exactly which structures are in, so anything added to Lambda later stays out of your link until you make a new one. To change a link later, open this page from it: your selection and class name come back filled in.
Your class
Shown above the title on the home page and beside the logo on every other page, so students know whose link they're on.
Lambda's author also sees private counts of how each class link is used, quiz results included, listed under this name, and can send you your class's report. No cookies are used, and nothing that identifies a student is recorded.
