PG problem file Explanation

Problem tagging data

Problem tagging:

DOCUMENT();

loadMacros(
"PGstandard.pl",
"MathObjects.pl",
"parserPopUp.pl",
);

TEXT(beginproblem());

Initialization: We need parserPopUp.pl

Context("Numeric");

$popup = PopUp(
  ["?","Red","Blue","Green"],
  "Blue",
);

Setup: To create a radio object, use $popup = PopUp([choices,...],correct); For details, see parserPopUp.pl.html The context is not really necessary, but multiple choice questions are often follow-up questions, so we leave it in.

Context()->texStrings;
BEGIN_TEXT
Is my favorite color red, blue, or green?
\{ $popup->menu() \}
END_TEXT
Context()->normalStrings;

Main Text: Since popup menus hide their choices, we write the entire list of choices into the question. It is essential to do this, otherwise a student who is working from a PDF copy of their homework won't know what the options are and won't be able to answer the question.

install_problem_grader(~~&std_problem_grader);

$showPartialCorrectAnswers = 0;

ANS( $popup->cmp() );

Answer Evaluation: We withhold feedback by choosing not to show partially correct answers. We use the standard problem grader, which gives full credit or no credit. For other graders, see weighted graders

Context()->texStrings;
BEGIN_SOLUTION
${PAR}SOLUTION:$PAR
The correct answer is \{ $popup->correct_ans() \}
END_SOLUTION
Context()->normalStrings;

COMMENT('MathObject version.');

ENDDOCUMENT();
