Problem with Adaptive Hint

Tags: educator how-to

A problem with an adaptive hint evaluates a student’s response, then gives the student feedback or a hint based on that response so that the student is more likely to answer correctly on the next attempt. These problems can be text input problems or single select problems.

Create a Problem with an Adaptive Hint

To create the problem illustrated above, follow these steps.

1. In the unit where you want to create the problem, click Problem under Add New Component.

2. In the problem editor, select Advanced problem types. Then select Problem with Adaptive Hint.

3. In the advanced problem editor, replace the example code with the code below.

4. Click Save.

<problem>
        <text>
                <script type="text/python" system_path="python_lib">
def test_str(expect, ans):
  print(expect, ans)
  ans = ans.strip("'")
  ans = ans.strip('"')
  return expect == ans.lower()

def hint_fn(answer_ids, student_answers, new_cmap, old_cmap):
  aid = answer_ids[0]
  ans = str(student_answers[aid]).lower()
  print('hint_fn called, ans=', ans)
  hint = ''
  if '0.05' in ans:
     hint = 'Make sure you enter your answer in cents'

  if hint:
    hint = "&lt;font color='blue'&gt;Hint: {0}&lt;/font&gt;".format(hint)
    new_cmap.set_hint_and_mode(aid,hint,'always')
                </script>
                <p>If a bat and a ball cost $1.10 together, and the bat costs $1.00 more than the
                ball, how much does the ball cost? Enter your answer in cents, and include only
                the number (that is, do not include a $ or a ¢ sign).</p>
                <p>
                        <customresponse cfn="test_str" expect="5">
                                <textline correct_answer="5" label="How much does the ball cost?"/>
                                <hintgroup hintfn="hint_fn"/>
                        </customresponse>
                </p>
        </text>
</problem>
