<div>Regarding homework, I tend to agree with you. However, I am not
using this part of the system as homework. These question sets are used
for reviewing for our state assessment at the end of the year, or for
the midterm. <br>
<br>
1) At that point, the students "should" be able to answer the
questions, since we covered the unit previously. This is a "practice
exam" situation; as you say, an exam expects correct answers on the
first try.<br>
<br>
2) The points earned are accumulated by teams, so there is incentive
for students to work together to help their teammates improve. There
are goofy trophies at the end of the review period for the winning
teams; in addition, the student's score (with a component from the team
results) is used as a test score. I find that if there are no points,
high school students will not do the activity.<br>
<br>
3) Their points accumulate; I do not look at their average. Thus, if a
student is missing a lot of questions early on, they just need to learn
from their mistakes and get subsequent questions correct. The weaker
student needs to do more problems to achieve the same score as the
stronger student, but they have the opportunity to get a high grade by
doing more repetitions.<br>
<br>
So, the students are not really in homework mode; they are practicing
the pressure of the test on material they should already know.<br>
<br>
Thanks,<br>

Bad idea...in my opinion.=20
<br>
One of the attraction of LON-CAPA was that you could get a wrong
answer and still get full credit when you succeed in a solution.
<br>
Student are in school to learn, and making mistakes is part of that
process. If you expect them to get it right on the first try, why are
they taking your class and not a more advanced class? Homework is part
of the process of learning and needs to be encouraged, a formative type
of assessment. Exams take care of the 1 try situation.

<div>Last year I limited to 1 attempt per problem. The students
wanted some way to determine what the actual answer was, so this year I
will see what happens allowing 4 tries.=20
<br>
<br>
However, my scoring system only gives them credit for problems they
answer correctly on the first try. Incorrect answers, or correct
answers after 3 or more tries result in negative scores, so there is
incentive to get it right the first time. Also, unanswered questions on
a sheet where at least one problem has been attempted yield large
negative values, so students can't cherry pick the easy questions.

<div>I can then set up a series of problem sheets (say, 50 of
them). Each student then sees 50 sheets of 15 problems each, where the
problems have been randomly selected from the main pool of several
hundred problems. Each student sees different problems with different
randomizations.

<div>It works pretty well, although it unfortunately does not
allow statistics on the problems. I guess problems are indexed by their

<div>Last spring I had to have Guy manually move/rename stuff,
partly due to my learning curve and partly because I do not have the
access to do these operations. I am reluctant to keep bugging him for
my problem manipulations. He has lots of serious stuff to do. On the
other hand, I don't know if I have enough time in the day to do this
through the web interface... Only a few days now until school starts!

<div>

</div>
=20
<div>I expect to add more problems to the pool twice a year, a
couple of hundred each time. It is very awkward not having the ability
to do mass deletes, moves, renames, and so on.
Apparently people running their own servers have root access=
, so
they routinely go in and do things with shell scripts. I have the
knowledge & experience to do this, but do not have that access
since I am hosted on the educog machine. In addition, I am perhaps
unusual in my structure and overall number of problems.=20

I am not sure ... why "library"?
