Goal:
Make homework more effective and efficient.

It increases the effectiveness of traditional homework as a learning tool by:

• Providing students with immediate feedback on the validity of their answers and giving students the opportunity to correct mistakes while they are still thinking about the problem. As one student said, “I can fix my mistakes while [the] problem is fresh in my mind. ”
  
  
• Providing students with individualized versions of problems which means that instructors can encourage students to work together; yet each student must develop an answer to his or her own version of the problem.

It increases the efficiency of traditional homework by:

• Providing automatic grading of assignments.
