Managing keywords and negations

Background

Keywords and negations are powerful tools to support a grading in the grading process:

  • assessmentQ can give an automatic score to answers to open questions based on the keywords it contains. 
  • The author can also work with linked keywords, i.e. keywords that need to appear together within a certain word range of each other before the candidate gets a score. 
  • Further, the author can work with bonus keywords, i.e. keywords that result in extra points when they appear within a certain range of another keyword. 
  • assessmentQ also takes into account negations within a certain range of keywords. For instance, when a keyword appears, but is preceded by not or no, the candidate will not get any points for the keyword. Negations can be defined by the author and depend on the language of the answer. 

When a grader starts grading the answer of a question that contains keywords, he will see which keywords are there, which are missing, and which are considered incorrect because of a negation. This is already a big help when evaluating answers. 

Further, the grader can add, edit or delete keywords and negations to further optimise the grading process. 

Warning: When a grader adds, edits or deletes keywords and negations,

  • the maximum score of the question will never change, as the maximum score was defined by the author.
  • the automatic score will be recalculated. For instance, 
    • a question contains 3 keywords, each worth 1 point
    • an answer contains 1 of these keywords, so the automatic score is 1 out of 3.
    • the grader adds a new keyword he found in this answer. 
    • Result: the answer contains 2 out of 4 keywords, but its maximum score remains 3. So the automatic score becomes 1.5 out of 3.
  • The final grade assigned by a grader will not change anymore, even if additional keywords were found in the answer afterwards.

  4. Click OK.
    Result: A window will appear listing all the answers where this keyword is present. When an answer already received a final grade, a warning icon is displayed next to it. You may want to review this answer and the grade you assigned to it. The automatic score is recalculated for all answers where this keyword is present, however, the final grade that was assigned does not change.
