Hi,

The image may have gotten stuck in the browser cache of the student. Shift-Reload in the browser would fix that.

In a few instances, the graph only had one clear point that the student could identify.  I changed the script to graph a larger range in both x and y, and I also changed the problem script to choose a smaller range of random integers as possible values for the slope = random1/random2.

The students who were having difficulties reported that they were still seeing the same version of the problem that they had originally had.  Some of them had run out of available tries for the problem, but I had increased the number of tries available for those students.

Did you mean that the revisions to the problem are not evident in your course, or that you want to force a new individual randomization of this problem for those students who had not yet received credit?
>> 
>> Gerd's comment refers to the former and all students should see the new version of the problem, unless you had specifically imported a specified version of the problem in your course.  e.g. "myproblem.12.problem" as opposed to merely "myproblem.problem"

>> If you were wanting students to receive a different individual radomization of the problem, there are ways, but to do it globally for only those students who had not already received credit could be rather tricky.....

>> I've done this before with customresponse questions so know I can resort to that if needed, but I'm curious about the new numericalresponse preprocessing capabilities. I have a part consisting of two numericalresponses. The only criteria for the second response is that it has to be greater than the first. The template for numericalresponse with preprocessing is at the level of the numericalresponse itself, not at the level of the part. So what I'm wondering is, can I access the answer of the first numericalresponse to verify that the second is larger than it via preprocessing (and if so, how?) or should I just stick with customresponse for this?  Thank you!
