** Using WeBWorK **

I have just edited a problem on an active homework set. The problem had twelve blanks within it so that a student could get anywhere from 0/12 to 12/12 on the problem. The students (most of them) did not know how to do the last four blanks in the problem.

So I edited the problem to remove the last four parts of the question. The homework set was just assigned a couple of days ago so many students had not tried the problem yet. However, for the few that did, many of them have scores of 8/12. After I have removed the last four blanks in the problem, they should now have 8/8 or C.

My question: Can I have webwork reevaluate all students on this particular question (or even on the whole set) based upon what the problem now says and what they have entered? In this way, I could manually instruct ww to go through all answers that are given and the students that have 8/12 would then be correctly given C for having completed the problem.

I suspect that the "scoring tools" may hold the answer to this but it is not obvious to me. Thanks in advance for any feedback about this.

Are their other situations where people would want the instructor to be able to submit answers for students?

By the way, I just added the option

record_answers_when_acting_as_student => $professor,

to my course.conf and nothing seems to have changed. I also tried it in the global.conf with same (non) result.

record_answers_after_open_date_without_attempts => "professor",
record_answers_after_due_date                   => "professor",
record_answers_after_answer_date                => "professor",

I simply copied the whole

%permissionLevels=

For this particular parameter it's safest to use John Jones suggestion and set this parameter from the web interface -- that way you don't have to worry about syntax.

The web interface adds the statement:

$permissionLevels{record_answers_when_acting_as_student} = 'professor';

to the file simple.conf.

In general when modifying permissions in a course it is probably best to use the complete description of the hash variable, in the form $permissionLevels{....} otherwise you risk unsetting other parameters.

(This adapts mike's suggestion since 'professor' has to be a number in this file.)
