DraggableProofs
Using Draggable Statements
This PG code shows how to apply a javascript-enabled collection of drag and drop statements.
| PG problem file | Explanation |
|---|---|
DOCUMENT(); loadMacros( "PGstandard.pl", "MathObjects.pl", "draggableProof.pl", ); |
The draggableProof.pl macro can be found in [OpenProblemLibrary/macros/MC/draggableProof.pl]. It is not yet part of the standard WeBWorK macros, so you have to place the file in your local macros directory for this to work. |
TEXT(beginproblem()); $CorrectProof = DraggableProof([ "Jason Aubrey", "Someone better than Jason but less than everyone else", "John Travis" ], [ "Don't complain about it", "\(x^2\)" ], SourceLabel => "Choose from these", TargetLabel => "Place the people in order of increasing usefulness.", ); |
Notice the format is: [ list of correct statements in order], [ list of incorrect statements in order], options |
Context()->texStrings;
BEGIN_TEXT
Select \{ $CorrectProof->numNeeded \} of the following.
$PAR
\{ $CorrectProof->Print \}
END_TEXT
Context()->normalStrings;
# Answer Evaluation
ANS($CorrectProof->cmp);
ENDDOCUMENT();
|
Notice, $CorrectProof->numNeeded returns the actual number of correct statements provided in the first list from above. |
