Answers Can Be Entered Into Answer Blanks in Any Order
This PG code shows how to allow students to enter their answers into several answer blanks in any order.
- File location in OPL: FortLewis/Authoring/Templates/Algebra/UnorderedAnswers1.pg
- PGML location in OPL: FortLewis/Authoring/Templates/Algebra/UnorderedAnswers1_PGML.pg
| PG problem file | Explanation |
|---|---|
|
Problem tagging: |
|
DOCUMENT(); loadMacros( "PGstandard.pl", "MathObjects.pl", "AnswerFormatHelp.pl", "unorderedAnswer.pl", ); TEXT(beginproblem()); |
Initialization:
We must load |
Context("Numeric")->variables->add(y=>"Real",z=>"Real");
$a = random(2,9,1);
$answer1 = Compute("x^$a");
$answer2 = Compute("y^$a");
$answer3 = Compute("z^$a");
|
Setup: |
Context()->texStrings;
BEGIN_TEXT
Rewrite the following expression without parentheses.
Simplify your answer as much as possible, and assume
that all variables are positive.
$BR
$BR
\( (xyz)^{$a} = \)
\{ ans_rule(5) \}
\( \cdot \)
\{ ans_rule(5) \}
\( \cdot \)
\{ ans_rule(5) \}
\{ AnswerFormatHelp("formulas") \}
END_TEXT
Context()->normalStrings;
|
Main Text: |
$showPartialCorrectAnswers = 1; UNORDERED_ANS( $answer1->cmp(), $answer2->cmp(), $answer3->cmp(), ); |
Answer Evaluation:
We use $showPartialCorrectAnswers = 0; install_problem_grader(~~&std_problem_grader); |
Context()->texStrings;
BEGIN_SOLUTION
${PAR}SOLUTION:${PAR}
Solution explanation goes here.
END_SOLUTION
Context()->normalStrings;
COMMENT('MathObject version.');
ENDDOCUMENT();
