Computer science · Middle school through college

The adaptive CS platform that runs on your curriculum.

Teach from open textbooks, publisher titles, or your own material, in one class. Practice adapts to each student, and the grading is already done.

Free forever for open content

Every class you teach. No credit card.

Enable every student to reach mastery

A tutor gets one student there. Alps is built to get all thirty.

The average student with a personal tutor scores two standard deviations above the average student in a regular class.

One class, three groups

You don’t sort the class. Alps groups students from the work they have already done, and regroups them as the class moves.

Still building fluency 7 students

Parsons problems and worked examples on loops.

On track 17 students

The standard set, with hints and a stretch problem at the end.

Ready for more 6 students

Nifty Assignments and harder problems that use the same skill in new ways.

Signed data privacy agreements

We sign a data privacy agreement with the districts we work with, and we’re a member of the A4L Student Data Privacy Consortium. Two are public here; the rest live in districts’ own systems.

Who builds Alps

Alps is built by 2Sigma School, named for Bloom’s 2 Sigma Problem. We taught computer science ourselves, and wanted that mastery for every student in a full classroom. Our research and development has been supported by the Institute of Education Sciences (IES) at the U.S. Department of Education.
