[LON-CAPA-users] How to mark certain responses to be hand-graded?

Hi Gene

Thank you for the quick response and the good idea.
I implemented it in a way that is demonstrated by the enclosed minimal example.
(The use of 'ASSIGNED_SCORE' I grabbed from the author guide page 48.)

Is this the way to go?
And a follow-up question --
To confirm the assignment of the score do I have to publish the problem and import it into a course?
Or, is there a way to show it in author space?

Thanks!
Itay

Minimal example follows:

<problem>
  <startouttext />
  Write down a solution to the quadratic equation <algebra>x^2 + 2x + 3 = 0</algebra>.  <br />
  Write the string 'NA' in case there is no solution.
  <endouttext />
  <customresponse id="11">
    <answer type="loncapa/perl">
      if ($submission =~ /^\s*NA\s*$/)        { return('ASSIGNED_SCORE', 150); }
      # Here, in a full problem, would go code that handles the other cases.
      return 'INCORRECT';
    </answer>
    <textline readonly="no" />
  </customresponse>
</problem>

I just tried, and was not able to “force” the Hand Grade parameter to show up for one of my quiz questions, so I’m not sure if it is possible.

When you download the grades to a spreadsheet you could sort them by score. Any 150’s would be at the top so you would know which ones to hand grade. This is not a great solution, and hopefully someone will have a better idea, but if not, since they are rare perhaps something like that could work…
