Extended Multiple Choice

Extended multiple choice questions are known as Checkbox Questions within EdX. 

The basic structure of a checkbox question in EdX is a scenario prompt, the question text in a <label> tag, then a <checkboxgroup> that includes all the possible answer options.

<p>The nurse is preparing to speak with the physician about the client’s plan of care.</p>
<label>Which of the following diagnostic procedures should the nurse anticipate the physician would order? Select all that apply.</label>
<checkboxgroup> 
<choice correct="true">barium enema</choice>
 <choice correct="false">abdominal x-ray</choice>
<choice correct="false">abdominal ultrasound</choice>
<choice correct="true">complete metabolic panel</choice>
<choice correct="false">esophagogastroduodenoscopy (EGD)</choice>
</checkboxgroup>


Edit the grading scheme:  For Extended Multiple Choice questions, the most common grading scheme is partial credit. In EdX that shows up as the <choiceresponse> tag.  If you want partial credit, you will add partial_credit=“EDC” which means “every decision counts.” 

<choiceresponse partial_credit="EDC">
<checkboxgroup>
<choice correct="true">barium enema</choice>


Add or delete checkboxes: Each checkbox is noted by a <choice> html tag. The text for that checkbox, if any, is between the <choice> and </choice> tags.

<choice correct="true">barium enema</choice>
<choice correct="false">abdominal x-ray</choice>

Change correct/incorrect answers: If you change a checkbox answer, you will also need to update the correctness of that answer. Correctness is noted as correct=“true” or correct=“false” within each checkbox html.

<choice correct="true">barium enema</choice>
<choice correct="false">abdominal x-ray</choice>
