LON-CAPA Help

externalresponse is an advanced type of response tag that implements the ability to have an external program grade a response. It expects either a textline or textfield inside the tag. Possible attributes are:

• url: url to submit the answer form to. It does not need to be a LON-CAPA machine.

• answer: data to post in the form element LONCAPA_correct_answer to the remote site.

• form: hash variable name that will be submitted to the remote site as a HTTP form.

The form sent will consist of

• LONCAPA_student_response full text of what the student entered in the entry field

• LONCAPA_correct_answer contents of the answer attribute

• LONCAPA_language specified language encoding of the requesting resource

• all items in the form attribute if any of these clash with the above, the above values will overwite the value in the form attribute

The response of the remote server needs to be in XML as follows:

• loncapagrade: takes no attributes, but must surround the response.

• awarddetail: required. The delimited text inside must be one of the detailed results that appears in the data storage documentation. CVS:loncapa/doc/homework/datastorage, look for resource.partid.responseid.awarddetail.

• message: optional message to have shown to the student.

 <loncapagrade>
    <awarddetail>INCORRECT</awarddetail>
    <message>
A message to be shown to the students
    </message>
</loncapagrade>
