CrowdGrader lets students submit and collaboratively grade their solutions to homework assignments. 

Students learn better: 

• They can see how their peers solved the same problems and learn from it.
• They get useful feedback.
• They build motivation by comparing their work with that of the other students. 

Instructors benefit: 

• They can easily handle homework grading in large classes.
• They can read all feedback and discover any difficulties encountered by students.
• They are in full control of the grades. 

CrowdGrader is simple: 

No complicated full-course setup.  Just create an assignment, and add your students -- or share with them a URL where they can self-enroll. 

Why not see for yourself?
