Using WeBWorK in CS1

1
Using WeBWorK in CS1

• Fall 2005 (Java)
• For in-class tests (multiple choice / matching)
• Spring 2006 (Python)
• For in-class tests (multiple choice)
• For homework exercises

Preparation

• More time upfront, less after (currently)
• Mitigating plagiarism random ordering of answers
  in multiple choice questions, parameterization of
  code in matching questions x out of y questions
• Importance of quality assurance
• Logistics - check clock synchronization, printing
  individual test papers

Students Perspective

• Positive
• Instant feedback self-assessment
• Issues questions
• Consequence of no hardcopy annotations, answer
  elimination?
• Matching questions text box size, multiple
  answers?
• Context complete, visibility of progress?
• Single attempt answer commitment (Shock to see
  results at the click of a button Where did I go
  wrong V so what?)
• Multiple attempts can lead to trial error (How
  assess?)
• Transfer of understanding between own programs
  variants demonstration of real understanding?

Lessons Professors Perspective

• Positive
• Class size (a helpful teaching assistant!)
• Can see who is attempting homework
• Quite straight forward to change questions to
  other programming languages
• Negative
• Going through solutions in class
• Granularity of feedback

5
Future

• Tailor questions dynamically to support specific
  student needs (to challenge or support)
• Compare mechanism for student learning
  references, hints, easier/harder questions
• Need more granular visual feedback on
  performance for students professors
• Possibility for alerts any common problems,
  trends?
