I can't help inserting my $0.02 here 8)  LON-CAPA is not a homework 
system, it is an assessment and course delivery system (and learning 
content management system, etc...). One of the strengths of the system is 
that the questions can be used in any number of pedagogical situations - 
we don't sit there and dictate how everyone must define and deliver their 

For homework, agreed - the multiple attempts is a good thing and tries to 
be formative in its application.

Here I give reading quizzes that are not difficult at all, nor highly 
randomized. Students get a series of multiple choice questions, have a 
time limit on the folder, DO get multiple attempts (because of slips of 
the mouse primarily), but do not get the status returned. The point is not 
for them to get immediate feedback but for them to take an online quiz 
that prods them to read. The answers open up a half hour before class when 
the quiz closes.

If giving an online practice test, one would presumably do something 

I agree that an instructor needs to think carefully about the mode in 
which questions are delivered, but the power of LON-CAPA is that it can 
allow a great variety of delivery modes for variety of styles 
of assessment.
