The orgininal problem may be viewed at

.
A ball with velocity vectors and components attached undergoes projectile motion. The question asks for the speed of the ball at a particular (random) time.

The modification utilizes the random parameter feature of the WebCT
calculated question format. The advantage here is that you can allow unlimited
attempts and encourage collaboration. Since the parameters are
re-randomized on each attempt, it is appropriate to report the correct answer after an incorrect submission.


The WebCT version of this question is at

http://webhw.unca.edu/bennett/WebCT/physlet_2d_1.zip
.
Download and unzip the file, and import into WebCT. A question database
category will be created called physlet_problems (if it does not already
exist).



Once you have the problem working, create a quiz that uses it. The quiz
settings that I find most effective for this problem are



  • Unlimited attempts

  • Highest score determines grade

  • Release the score once the quiz has been submitted

  • Show the student's response for each question

  • Show the correct answer for each question
