Sequentially Revealed (Scaffolded) Problems

Click to enlarge

This PG code shows how to create multi-part questions that hide from students parts that have not yet been answered correct.

PG problem file Explanation

Problem tagging data

Problem tagging: 

DOCUMENT();  
loadMacros(
"PGstandard.pl",
"MathObjects.pl",
"compoundProblem5.pl",
"PGcourse.pl",
);

TEXT(beginproblem());
$showPartialCorrectAnswers = 1;

$scaffold = Scaffold();
INITIALIZE_SCAFFOLD('$scaffold');

$isInstructor = 0; # = 0 when students use it

TEXT(MODES(
HTML=>'Clicking on a section opens it 
provided that you have answered previous sections correctly.',
TeX=>''));

Initialization: Use the compoundProblem5.pl macro to provide scaffolding (this macro may be renamed to Scaffolding.pl or sequentiallyRevealed.pl in the future). We initialize the scaffolding with the name $scaffold. Set $isInstructor = 0; when the problem is available to students, or set to 1 when debugging. Alternatively, we could set 

$isInstructor =  ($envir{effectivePermissionLevel} >= 
$envir{ALWAYS_SHOW_SOLUTION_PERMISSION_LEVEL});

to ensure that only users that always have permission to show correct answers can open all of the sections of the scaffolding without needing to enter correct answers. 

Context("Numeric");

$answer1a = Compute(11);
$answer1b = Compute(12);

Context()->texStrings;
DISPLAY_SECTION({  
    section=>1,
    name=>"1: Antiquated ideas (a descriptive title)", 
    canshow =>1,
    iscorrect=>$scaffold->requireCorrect(1,2), 
} , <<'END_SECTION'); 

Continue the pattern: 7, 8, 9, 10, 
\{SECTION_ANS($answer1a->cmp), $answer1a->ans_rule(3) \},
\{SECTION_ANS($answer1b->cmp), $answer1b->ans_rule(3)\}.

END_SECTION

SECTION_SOLUTION({section=>1},<<'END_SOLUTION');
$PAR
Put some text here for the solution to section 1.
END_SOLUTION
Context()->normalStrings;

Section 1: Use DISPLAY_SECTION to set the parameters for the first section. Use section=>1 to set the section number. Use name=>"1: Descriptive title" to give a title for the section. Since the first section should always be available to students, we set canshow=>1. Use iscorrect=>$scaffold->requireCorrect(1,2) to specify that this section will be marked all correct when the answers in answer boxes 1 and 2 are both correct.

The text that gets displayed to students starts at "Continue..."

Use SECTION_ANS() to record the correct weighted score into the grade book (i.e., database of scores). Note that we use SECTION_ANS($answer->cmp) before $answer->ans_rule(width), which is a bit different from how things are usually done.

It is also possible to provide a solution for each section. 

Context()->texStrings;
