Your title here: PG Code Snippet


This code snippet shows the essential PG code to check student answers that are equations. Note that these are insertions, not a complete PG file. This code will have to be incorporated into the problem file on which you are working.

Problem Techniques Index

PG problem file Explanation
DOCUMENT();
loadMacros(
"PGstandard.pl",
"MathObjects.pl",
);
TEXT(beginproblem());

Initialization: To do ..(what you are doing)........., we don't have to change the tagging and documentation section of the problem file. In the initialization section, we need to include the macros file -------.pl.

Context(".....");
Define context and  variables for the questions

$expr = Formula("....");

Setup: We specify that the Context should be ......, and define the answer to be a formula.

Notes: on using this and related Contexts.

BEGIN_TEXT
...... question text ......
END_TEXT

Main Text: The problem text section of the file is as we'd expect.

$showPartialCorrectAnswers = 1;

ANS( $expr->cmp() );

ENDDOCUMENT();

Answer Evaluation: As is the answer.
